What's new

Added

• Alignment guides: while you drag shapes, blocks, notes or parts, construction lines show where an edge (dashed) or the centre (a chain line, like the axis of a technical drawing) lines up with something else on the screen, with a small cross on each box, and the move sticks to it. Shapes line up even off the grid; parts stay on it. Hold Alt to move without the guides.
• Zoomed out, the sheet reads like a map: frame names and block titles stay readable, while the names of pins, the references and values of parts, net labels, port names and small texts make way. Far out, junction dots stay visible, the grid changes scale and the badges make way. Zoom in and everything comes back.
• Paste text from ChatGPT or a web page with Ctrl+V: it becomes a text at the pointer, with its bold words, bullets and formulas. ChatGPT’s \( … \) and \[ … \] become LaTeX (a formula set apart is drawn large, alone on its line), and prices like $5 stay dollars. A long text wraps; one Ctrl+Z takes it back.
• A web address pasted alone becomes a link button named after its site.
• Pasted while you write a text, a note or a name, text goes at the caret, cleaned the same way (a name stays on one line).
• Bold and italic words: write **bold** and *italic* in a text, a sticky note, a shape or on an arrow. The stars are not drawn; R* or a * b stay as typed. The exports and CircuiTikZ follow. A dollar sign that is not a formula is written \$.
• A formula alone on its line is drawn large, also inside a longer text.
• Connectors that cross get a small bridge, like wires: the horizontal one jumps over the other (a curve or a hand-drawn line never jumps: the one crossing it does). The CircuiTikZ export draws the same bridges.
• A selected line or arrow gets a soft halo that follows it, instead of a large grey frame around it.
• Crop an image: double-click it, move the frame, pick a ratio (free, 1:1, 4:3, 16:9).
• Remove the background of an image: a plain background, a photographed page, or the subject of a photo found by an AI that runs in your browser (downloaded once, about 46 MB).
• Images get rounded corners, an opacity, a border, Replace image… and Original size.
• Give a project a cover: a picture framed 16:10, or another of its sheets (Change cover… in its menu, or in the editor when nothing is selected). A shared project’s cover is changed by its editors and seen by everyone in it.
• Tables: the Table tool (Shift+T) puts a table on the sheet; write in its cells in place, Tab for the next cell, Enter for the one below. Text and LaTeX in every cell.
• Paste cells from Excel, Google Sheets, a web page, ChatGPT or a markdown table: they become a table. A .csv file dropped on the sheet does too.
• The Table panel adds and removes rows and columns, aligns columns, and copies the table for Excel or as a LaTeX tabular.
• Task boards: a kanban on the sheet (Shift+K) with To do, Doing and Done. Add a card in place, drag it to another column, double-click to rewrite it.
• Give a card to the people of the project: their initials show on it in their colour. Tick it done. The status bar tells you how many tasks are yours.
• Rename, add and remove the columns of a board in its panel.
• Tables work like a spreadsheet: a click picks a cell, Shift a rectangle, Ctrl one more cell; type to write, arrows to move, Delete to empty. The table moves by its border.
• Each cell can have its own paper, bold, italic, colour and alignment, set for all the cells picked at once; they show in the exports and in LaTeX.
• Task boards: a click picks a card, Ctrl picks several; give them to someone, tick them done, move or delete them together. The column a dragged card lands in lights up.
• Shadows like draw.io: tick Shadows in the project’s Drawing style for a soft shadow under shapes, sticky notes, framed texts, images, blocks, tables and task boards, on screen and in every export.
• Ctrl+V pastes what you copied right under the mouse pointer, parts and wires still on the grid. Pasted again without moving, each copy lands a step further, so they do not hide one another. The same in the symbol editor.
• Double-click an empty spot of the sheet, inside a frame too, to write a text right there.
• Defaults for new elements (View menu): the font, size and weight of new texts, hand-drawn shapes and their fill, hand-drawn lines and arrows, the paper of new sticky notes. They are yours, for all your projects; what is already drawn keeps its look. “Use as default” under a selected text, shape, arrow or sticky note.
• The right panel is tidier: Arrange, Text, Style, Link, Visibility and Animation start folded, with their values on the heading. A section you open stays open.
• Fill a shape or a text plain, in coloured pencil, or with a highlighter that passes behind the words. The same in the exports.
• Name a pin in the symbol editor and the name is drawn beside it: inside or outside the body, along or across the pin, with its number and a dot if you want.
• Texts of the symbol editor turn and align left, centre or right; hold Alt to place anything off the grid.
• Turned parts turn their pin names with them, always readable: no more names running into each other.
• Symbols of a shared project keep their author: choose whether the others can only place yours or also change it. Someone else’s symbol opens read only, with a button to duplicate it. The library shows who made a symbol and finds symbols by their author.
• Pull the end of a wire or a signal line: select it and drag the small square on one of its ends to make it longer or shorter, or to take it off its pin and drop it on another pin, a point of a shape or a wire. What is connected along it stays on it, and its last corners stay square, clear of the other pins and of the parts.
• A selected wire has a small bar in the middle of each piece: drag it to move that piece, without clicking the wire twice first.
• Draw an arrow from a shape: with the select tool, hover a shape, a sticky note, an image, a table or a task board, press on one of its points and drag to another element. It is drawn like the line tool draws, attached at both ends.
• Shapes, sticky notes, images, texts, tables and task boards have 16 connection points instead of 8: the corners, the middle of each side and a quarter of the way along it. Wires hold on to all of them; an arrow can also attach anywhere along the outline (on the grid; Alt: exactly there) and stays at that place when the shape moves or grows.
• Defaults for new elements: the ends of new lines (line, arrow, double arrow, dashed) and their route, the ink of new wires and of new signal lines, the arrows and dashes of new signal lines. “Use as default” under a selected wire or signal line.
• Drag from a pin and let go on another pin or a wire: the wire is done. A pin lights up from about 10 px away, with a wire pointer.
• Wires find their own way around the other pins, wires and parts: no more hidden shorts along a column of pins.
• A part with both pins on the same net is ringed in red, and the status bar says “R1 is shorted”.
• Let go on a part away from its pins, or draw a second wire between joined points: the status bar says why nothing happened.
• Search the library in your own words: “arduino”, “12 V source”, “RC filter”, “op-amp”, “10k” or “R” find the right part first, names before keywords.
• Arduino Uno, Arduino Nano and ESP32 DevKit in the library, with their pins named as on the board.
• Five starter circuits in the Templates tab: voltage divider, RC low-pass filter, LED and resistor, non-inverting amplifier, Arduino and LED. A library search shows them too.
• A plain Block for system diagrams: its name is ordinary text (“LoRa radio” keeps its space), with 0 to 6 inputs and outputs.
• New projects start with an empty name field; “Untitled project” is only a hint.
• Names typed in a block are written as plain text, not maths (“LoRa radio” keeps its space).
• Export: “PDF” instead of “Smart PDF”, “Copy as image” second; CircuiTikZ loads hyperref only when there are links.
• Task boards: Ctrl+Enter writes the next card, letters typed on a card go into it, and “Share the project” shows the way to your group.
• “Create an account” in the top bar of a project kept in this browser.
• Pasted texts, tables and pictures land in a free, visible spot; “Zoom to fit” ignores what covers the sheet.
• A bare value such as “10k” is shown with its unit (10kΩ); what you typed is kept.
• “Change cover…” is also in the project menu next to its name, and offers the pictures already in the project.
• Invite people by e-mail or @username, with a role, right from the Share button. An e-mail invitation works once, for that address only, for 7 days; the people you invite see it on their projects page.
• Invite links are for one person by default; “Anyone with the link” is still there.
• New role “Can view, no export”: look and present, but no export, download or copy (it cannot stop a screenshot).
• Access per sheet shows as soon as a project is on the server.
• The Share dialog says where your projects are stored: in the EU (Germany), behind Cloudflare.
• The Export window shows a preview of the image, redrawn when you change the colours, the background, the format or the margin.
• Square 1:1, Portrait 4:5 and Landscape 16:9 images (PNG, SVG, Copy as image) with the drawing in the middle, for a post or a slide.
• CircuiTikZ: resistors, capacitors, inductors and diodes carry their name and value (l=$R_1$, a=…), even when turned.
• Words of the notebook: rest the pointer on a tool or a part whose name is jargon (hierarchical block, sheet port, net label, signal line, frame, generic block G(s), junction dot…) and a small card says what it is for, with a tiny drawing. The first time you use one of these tools, the status bar says it too; the manual has the same list.
• Keep my notes: at the end of a presentation, put what the pen wrote on every slide on the sheet in red pencil, in one undo step, or download the annotated slides as a PNG.
• A blackboard beside the slide (Shift+B): the slide on one half, the board on the other; those who follow you see the same.
• Esc puts away the blackboard, then the pen or the laser, then ends the presentation.
• Every tool, the sections of the right panel and the buttons of the presentation bar show the small card with what they are for, a tiny drawing and their key; the manual’s Words of the notebook lists them all, in four parts.

Fixed

• In a line with a formula, accented letters (é, è, à, ê, ç…) no longer leave a gap after them, and their accents are drawn in the LaTeX font.
• Only the editors and the owner of a shared project can rename it: for the others its name is shown but cannot be written in. Rename is also in the project menu of the editor, next to Change cover…, and in the menu of a shared project’s card.
• A tap on the hidden control bar of a presentation brings it back instead of drawing on the slide: “End the presentation” works the first time.
• Pasting text copied outside the app no longer pastes again the elements copied earlier in the app.
• On a turned shape, the resize handles turn with it, and the pointer shows the way each one really pulls.
• A selection zone drawn right to left inside a slide no longer selects the slide: a frame is taken only when the zone crosses its border or its name tab.
• Inside a frame with a fill, dragging on an empty spot draws a selection zone, as in any frame.
• A formula or a word too wide for its table column is set smaller to fit, never drawn over the next cell. The people on a task card sit side by side.
• Handwritten texts are measured again once their font has arrived: their frames and fills fit the words.
• The Signal line tool says what it is for: joining the blocks of the library (Control). Between shapes, the Line / arrow tool (Shift+L) is the one: its arrows hold on to the shapes and go around them. The manual says it too.
• The line tool’s choice of line, arrow, double arrow or dashed line is kept for next time.
• Typing fast on a picked cell of a table no longer loses the first letters: what is typed before the cell is ready to be written in comes first.

Added

• Names are written where they are drawn: the name of a new block, port or net label, a frame and the text of a link button, in their own font and size, with nothing around them; what is proposed ("Block 1", "net") is selected, so you type over it. Zoomed far out, a small card above the element says what you are naming (and no longer covers it).
• The title of a hierarchical block takes a font (LaTeX or handwriting), a size, bold, italic and a colour, in the Text section of the right panel; a title too long for its block gets smaller to fit. "Hand-drawn" draws the block with a pencil.
• A sticky note or a link button is drawn at its size: drag with the tool, or click for the usual size.
• A line with right angles moves segment by segment, like a wire: click one of its segments to pick it, then drag it (or drag the small bar in its middle). Moving the first or the last segment adds a little jog, so the end stays on its shape. The segments keep their places when the shapes move; "Automatic route", in the right panel, lets the route find its own way again.
• A straight line or arrow turns with the mouse: drag the round handle beside its middle (it sticks to steps of 45°; Shift: 15°). It turns around its middle, or around its end attached to a shape, which stays attached.
• A pencil stroke alone gets the frame of a selection: its corners make it bigger or smaller, its round handle turns it.

Fixed

• With the pencil (or a line, a shape, the text tool…), what is under the pointer no longer lights up: only the select tool and the eraser show it.
• Right angles, chosen in the options of the line tool, only applied to a line between two shapes: drawn anywhere else, the line came out straight, and dragging its middle curved it. Right angles now apply to every line, and the line shows them while you draw it.

Added

• Texts are written like on paper: a click with the text tool and you type right there, in the text's own font, size and colour, with nothing around it. A new text starts empty (no "Text" to erase); Escape or a click elsewhere ends it and keeps it; a text left empty leaves nothing, and a text emptied is removed.
• A box drawn with the text tool sets the width the text wraps at, and the two small handles on the sides of a selected text change it.
• A formula alone is drawn large, as in a textbook (fractions at full size), and the box of every text now fits what is drawn.
• While you write, the LaTeX help sits in the top right corner of the sheet, with the formula as it will look. New: matrices (in parentheses or brackets, 3×3, a determinant, a column vector), systems with { and equations aligned on =.
• Typing sounds clearer: a soft key tap, lower for the space bar and lighter for the back key.
• The top bar is lighter: the grid, the animations, the sounds, the two panels and the theme are in one "View" menu; the shortcuts and tips, the shortcuts to change, what is new and the manual are in the "?" menu.
• With nothing selected, the right panel says only what you need: the name of the sheet, whether it goes in the presentation and the PDF, and the drawing style of the project, folded (it is set once). Its explanations are in a small (i) you can point at.
• What the sheet holds (its parts, wires, blocks and ports) is in the status bar, at the bottom.
• On a blank sheet, the right panel reminds you that A adds a part.

Fixed

• The frame of a selected formula was much wider than the formula: it was measured on its LaTeX code, not on its drawing.
• A text typed in a box drawn with the text tool wrapped while it was typed, then spread over one long line once done.
• Escape used to throw away what had just been typed in a text: it now keeps it.
• Escape closing a menu of the top bar no longer also takes you up out of the sheet.
• The "Day and night" slide of the night pumpkin said the base reaches 8 V at night: it is held at 0.7 V.
• The right panel no longer repeats the drawing standard (EU / US is in the top bar) nor says "Can edit" when you can.

Added

• Sheets from the Sheets tab: "New sheet" adds one to the project, the + of a sheet adds one inside it (a sheet can hold others, as deep as you like), the bin deletes a sheet with the sheets inside it (Ctrl+Z brings them back), and a double-click on a name renames it. Each new sheet is also a block on the sheet above it, placed under what is already there.
• The pencil draws like a good pen: the thick and thin parts of a line come from the speed of your hand (a slow line is pressed, a quick one light) and both ends taper. With a stylus, its pressure still decides.
• Chalk looks more like chalk: a finer grain that keeps its size at every zoom, a stroke that covers better, and a little powder around it.
• The edges of the side panels have a grip in their middle: it shows where to drag them to make a panel wider or narrower.

Fixed

• A line drawn zoomed in came out much thicker and blurrier than the same line drawn zoomed out (up to three times as thick). It is now the same at every zoom, and as precise zoomed in as out. The lines drawn before keep their look.

Added

• A profile picture: in your account menu, "Edit my profile". Choose a picture, drag and zoom it to frame it in the circle. It shows in your account button, to your friends and teams, to the people of your projects and next to your cursor when you work together. Your name and your colour are there too.
• Themes are behind one button now: it opens the list of themes, each with a preview and a few words.
• A new theme, Slate: the darkest one, a slate board in chalk, for a dark room or a projector.
• Chalk, next to the highlighter in the options of the pencil: grainy strokes of even width, white on a dark board and black on paper (or any colour you pick). A little chalk dust falls while you draw. Change the look of a stroke later in the right panel (pencil, highlighter, chalk).
• The blackboard of the presentations (B) is drawn in chalk too.
• Soft sounds: a pencil or chalk on the board while you draw, a light tap for each letter you type on the sheet, a click when a wire lands on a pin, a pop for a new part, a whoosh when you delete, and small notes for undo, redo and the steps of a presentation. They are quiet and in tune with each other. Turn them off with the speaker button, next to the animations one (on a phone: in More).

Added

• Presenting is clearer: next and back go through the frames of the sheet on screen only. The slides of a hierarchical block are no longer added after those of the main sheet: click the block to go in, and after its last slide the next click takes you back out, where you were (same slide, same click).
• F5 starts on the main sheet (or on the first sheet that has something to show). Shift+F5, or Shift-click on Present, starts on the sheet you are on.
• Going back out of a block, the camera rises from the block, as it dived into it. A button linking back to the sheet you came from does the same.

Fixed

• The sheets of the blocks came after the frames of the main sheet, in an order you could not choose.

Added

• B now shows a blackboard: draw on it in chalk with the left or the right button, point with the laser (L), wipe it with C. Only B or its button takes it away, and what you drew is still there the next time.
• Those who follow your presentation see the blackboard and your chalk too.

Fixed

• On the black screen nothing worked: a click closed it, the right button went back one slide without showing it, and the laser could not be seen.
• With the pen, the right button drew and went back one slide at the same time (losing the stroke).
• Following someone, a click or an arrow key moved your own slides away from theirs.

Added

• Drag the name of a pin of a hierarchical block to move the pin along the edges, or to another edge. The wires on it follow. The other pins still spread out on their own; "Spread the pins again" in the right panel puts them all back.
• Pin names on the top or bottom edge of a block are written upwards when they would run into each other.
• Drag the reference and the value of a part (R1, 10 kΩ) to another place. They follow the part when it moves or turns; "Labels back in place" puts them back.
• Bridges: where two wires cross without a junction dot, the horizontal one jumps over the other with a small hop, as on a classic schematic. Also in the exports and in CircuiTikZ. Turn it off with "Bridges where wires cross", next to the line thickness (right panel, nothing selected).
• Delete a domain or a category of your own symbols, or a category of your templates (the bin on its header): keep what it holds, or delete it too.
• Drag one of your own symbols onto a domain or a category of the component list to move it there (built-in symbols stay where they are).
• Watching someone present: you now see their mouse, their laser pointer and what their pen draws. Pen strokes stay on the slide (they move with it).

Fixed

• A block could not be clicked under a shape or an image, even sent to the back: blocks were always drawn behind everything. They now follow the drawing order like the rest (only frames stay behind).
• The round handle that turns a part was very far for some symbols (bridges, three-phase inverters, ICs). It now sits just above the part and its labels.
• Undo after changing a port inside a sub-sheet could remove the whole sub-sheet. Undo now only takes back that change.
• With a comment open, the keys of a presentation (L laser, P pen, B blank) went to the comment, and Delete could remove it.

Added

• Drop a part or a block on a wire: when both its pins land on it, the wire under it goes and the part takes its place. A loose wire end right next to a pin joins it. Green rings show it while you drag; Ctrl+Z puts the wire back.
• A graph editor (double-click a graph): a large preview, the curves in a list, signals and presets sorted by type.
• Bode plots (magnitude and phase, asymptotes) and pole-zero maps in the s-plane or the z-plane, from a first order, a second order, an integrator, a lead-lag or your own poles and zeros.
• New signals: ramp, damped sine, square wave with levels ±1, triangle with any rising part (a sawtooth at the end).
• Animation "Change a curve": on a click, the phase, frequency, amplitude, duty cycle, damping or gain of a curve glides to a new value. Leave From empty to chain steps (0° → 90° → 180°); "Keep going" turns the phase forever.
• Shapes, images, graphs, sticky notes, texts and buttons turn to any angle with the round handle above them (Shift: steps of 15°); R still turns by 90°. An Angle field in the right panel.
• Parts turn to any angle with their round handle and take any size from their corners; R keeps the quarter turns and the Size list its ×1.5, ×2, ×3.
• Several things selected, or a group: one frame around them, whose corners make them bigger or smaller together and whose round handle turns them together.
• The symbol editor takes the whole window: zoom and pan, several things selected at once (Shift+click, a zone), handles to move points, resize and turn, R / X / Y, copy and duplicate, a polyline that ends with a double-click, built-in symbols sorted by domain, and domains of your own.
• Hierarchical blocks get a subtitle, and an illustration in their middle: a symbol of the library, a shape or an image.
• The LaTeX bar ($…$, fractions, Greek letters…) on every field that takes LaTeX: block titles, values, port and net names, labels of arrows and graphs.
• Underline, next to bold and italic, for texts, shapes, notes and arrow labels.
• Your symbols and your templates are exported as two files, from their own tab.
• Shape menu by group (Basic, Lines, Flowchart) with larger drawings and their names; plain lines, arrows, double arrows and dashed lines.
• A Graphs domain in the library: axes with one, two or four quadrants, the complex plane (with the unit circle) and 3D axes.

Fixed

• Some fields rewrote what you typed: you could not add points to a custom curve, nor type a size, a duration or a period freely. They now keep the text while you type and tidy it when you leave the field.
• Labels of curves ending at the same place overlapped: they now spread apart, with a thin line to their curve.
• A turned shape was stretched instead of turned; four quarter turns no longer make it drift.
• Mirror really flips shapes, in place; sticky notes, buttons and images no longer jump when they turn alone.
• Changing the alignment of a framed text moved its frame.
• Arrows attached to a turned shape stay on the same side of it.
• Shapes that looked the same are now one each (a data shape is a parallelogram, a database a cylinder…).
• CircuiTikZ export: turned shapes, dashed curves, the grid and the labels of graphs.

Added

• Line thickness of the project (right panel, with nothing selected): one for wires, one for parts, one for drawings. Everything left on Default follows it, also in the exports and for everyone working on the project.
• Junction dots grow with thick wires, so they stay visible.

Fixed

• A wire started on a shape is often off the grid; a wire branched off it stopped a few px short, with a loose end and no junction. It now lands exactly on it. Same for net labels and animated currents.

Added

• Wires and arrows attach to 8 points of shapes, texts, sticky notes, images and frames (the middle of each side and the corners), and follow them when they move or change size.
• A Text section for texts and for the text of shapes, notes and arrows: size, bold, italic, alignment, colour.
• Handwriting: a font that writes like a pencil note, for any text; hand-drawn shapes use it.
• Text in shapes on several lines, edited right where it is drawn.
• The component list folds by domain (Electronics, Control, Other) and category, and remembers what you opened; the best search match comes first.
• Symbol editor: undo and redo, every category in a list, a domain for your own symbols.
• Template categories fold; drag a template onto another category to move it, rename a category.
• Sign in with Google (when the server offers it).
• The history of a project shows how full it is; delete the saved versions you no longer need.
• On a phone, tap the left third of the screen to go back in a presentation, anywhere else to go on.

Fixed

• Thyristor family: TRIAC and DIAC with proper triangles, clearer GTO and IGCT gates.
• IEC logic gates: their sign (&, ≥1, =1) centred in the box, and printed in PDF exports.
• ADC and DAC redrawn, centred (IEC square, US arrow). Check the wires on their pins in older drawings.
• Hand-drawn shapes look like a steady pencil: real curves, corners that meet, plain fill, dashes and rounded corners kept.
• The category field of the symbol editor only offered the category already typed.
• Escape closed the symbol editor and lost the drawing.
• Library import checks the file: a damaged entry no longer breaks the panel.
• Arrows now follow a text box whose size or text changes, and let go of a deleted shape.
• The presentation bar fits a phone screen, and turning a tablet no longer restarts it.
• Versions saved by hand had no limit: the history of a project now has a ceiling (20 MB, 30 saved versions by default).

Added

• Hierarchical schematic editor: blocks, sheets and ports; IEC and US symbol libraries; wires with automatic junction dots.
• Wires that follow what they are attached to; click a selected wire again to pick one piece (cut at the junctions), then drag it or delete it.
• Text and LaTeX everywhere, with a math bar ($…$, fractions, indices, Greek letters…).
• Whiteboard tools: shapes and flowcharts, arrows, sticky notes, pencil, images, waveforms and frames.
• Your own symbols, templates and a personal library.
• Presentation mode with animations (appear, emphasis, colour, move, change state, animated waveforms, typed text), transitions and slide order per frame, laser pointer and pen.
• Animated currents: dots, electrons, arrows or comets flowing through the selected wires in the presentation, with DC, AC, ramps, ripple or PWM currents that can reverse.
• Overview, then zooms: frames inside a frame each build up their own part; coming back from a block or a link returns to the same click.
• Exports: smart PDF, PNG, SVG and CircuiTikZ for LaTeX.
• Working together: accounts, sharing with people and teams, rights per sheet, live presence, comments and history.
• An example project that walks through all of it, as a presentation.
• Accounts confirm their e-mail with a code, and a forgotten password can be changed the same way.
• Folders for your projects (with an account): any colour, one inside another, by drag and drop.
• A phone version, a user manual, and this list of versions.
