InfinitiCanvas is a buttery-smooth, pen-first digital whiteboard that runs natively on your Windows computer — for teaching a lesson, taking maths notes, sketching an idea, recording an explainer or mapping out a plan. Try every feature free for 14 days — no card, no signup. Buy only if you love it.
InfinitiCanvas
Built by a teacher and proven in over 1,200 hours of live online instruction — and just as handy for notes, sketches, videos and plans.
InfinitiCanvas — Geometry / Pythagorean Theorem
✓ LICENSED
The last three releases added the tools teachers kept asking for: lasso-select to move groups of ink and images together, group resize & rotate, pencil / highlighter / ballpoint / typed-text, straighten-shapes recognition, ruled / grid / dot-grid page templates, and real stylus palm rejection for touchscreen convertibles. All of it still runs locally on your Windows machine — no account, no cloud, no telemetry.
See what’s new in detail →No bloat. No cloud lock-in. Just the tools you reach for ten times an hour, polished until they disappear.
Pan, zoom, and write across a 100,000-pixel surface. Never run out of room mid-derivation again.
Pen, eraser, and pan with frame-accurate stroke smoothing. Your handwriting looks like itself, not zigzag-vector-art.
Tab through warm-ups, examples, practice, and homework — each on its own page with a custom name.
Switch instantly between Infinite, Desktop 16:9, Tablet 4:3, and Mobile 9:16 framing for shorts and reels.
Auto-saves every stroke and restores everything on next launch — pages, colours, view, all of it. Unlimited undo/redo the rest of the time. Close the app mid-thought without a second thought.
Drop today's working into Notion, an LMS, or an email in seconds. Files save as native .infiniticanvas projects, too.
Full light/dark UI toggle that follows your Windows theme automatically. Twelve canvas background presets, and right-click any colour swatch to set your own — save your two or three teaching colours to the toolbar so you never dig through a picker mid-lesson.
Drag a virtual ruler onto the canvas, rotate it to any angle, and the pen snaps to its edge — geometry proofs and vector diagrams the way you'd draw them on a real board. Or press L for a quick one-off straight line with Shift-to-snap.
Native desktop app. After activation, InfinitiCanvas never phones home. No accounts, no cloud, no internet required.
The same endless, pen-first page works for lessons, notes, sketches, videos and plans.
Write worked examples live on a projector or over Zoom, Teams and Meet, then send the board as a PNG.

InfinitiCanvas — Algebra II / Lesson 9
The latest release adds lasso-select, group resize & rotate, straighten-shapes, three new pen types, typed text, page templates, palm rejection, and more — all included in every license, including the limited-time $20.
Drop the virtual ruler on your board, drag it into place, and rotate it to any angle. The pen tip snaps to its edge as you draw — every line comes out straight, even on a fidgety day. Tap the R key to hide it just as fast.
Ctrl + V drops any image straight onto your canvas — a textbook clipping, a screenshot from a PDF, a photo you snapped. Annotate with the pen, move it around with the Select tool. The eraser only removes your ink; the image stays intact.
new in 1.3On a touch-screen convertible (Surface, HP Pavilion x360, ThinkPad Yoga), your palm no longer confuses the pen. Only the stylus's strokes count — your wrist can sit on the glass while you write close and small. Fixed in 1.3.0 after a Wacom Bamboo report from a working teacher.
new in 1.3Warm-up, examples, practice, homework — keep the whole lesson organised across pages inside a single session. Everything auto-saves as you go, and opens right where you left off next time you launch the app.

Either works and both start the same 14-day free trial. Microsoft Store is the easier path for most people — one click, auto-updates, no "unrecognised app" warnings. The direct .exe download is there for people who can't use the Store (some school-IT policies block it) or want an offline installer they can copy to another machine. If Windows shows a "Windows protected your PC" screen when running the direct installer, click More info → Run anyway — that's standard for new independent Windows apps.
Yes. Download, install, and use every feature for 14 days without giving us a card or an email. The trial counter starts on first launch and runs entirely on your machine. Only after the trial ends does the app ask for a license key.
Yes. $20 one-time during the current limited-time window (regular price $49), no renewals, no surprise charges. Whatever you pay once, you keep forever — including every future update. Buyers at this price get all future features at no extra cost.
Until InfinitiCanvas hits a milestone number of lifetime licenses sold, after which the price steps up toward the regular $49. There’s no fake countdown timer — just a straight-forward "it goes up when it goes up." If you’re interested, buy now at $20 and skip the question. Anyone who buys at $20 keeps their license forever at that price, including every future update.
Yes. Both during the trial and after activation, InfinitiCanvas runs entirely offline. It does not phone home, does not upload your work, and does not require an account.
Every stroke you draw is auto-saved to your computer within a couple of seconds. When you reopen the app, your pages, colours, view, and canvas mode all come back exactly as you left them — no "recover unsaved work" dialogs, no lost lessons. The file lives in your user folder, not the install folder, so it survives updates and reinstalls too. If you ever want to start from a blank canvas, there's a New Session button in the toolbar that resets everything with a confirm prompt.
Yes. There's a sun/moon button at the top-right of the toolbar that flips the whole UI between light and dark. On first launch the app also follows your Windows theme automatically — if you're already using Windows in light mode, InfinitiCanvas opens in light mode with no clicks needed. Your choice is remembered across restarts.
Yes. Press R or click the ruler button in the toolbar and a virtual ruler with tick marks appears on the canvas. Drag its body to move it, drag the round knob at the right end to rotate to any angle. When your pen comes near its top edge, strokes snap to it — perfect for geometry proofs, vector diagrams, engineering statics, anything where you'd reach for a physical straight-edge. For quick one-off diagonals without the ruler on screen, there's also a straight-line tool (L) with Shift-to-snap constraints.
Right-click any colour swatch in the toolbar to change that slot to any colour you want. Your palette is remembered forever, so you can set your two or three teaching colours once and stop reaching for the picker mid-lesson. Right-click the dashed "+" slot if you ever want the original seven back.
Yes. Take a screenshot with the Windows Snipping Tool (Win+Shift+S) or any other tool that copies to the clipboard, then press Ctrl+V on the InfinitiCanvas canvas — the image drops onto the centre of your current view. Draw and annotate on top of it with the pen tool. To rearrange it, resize it, or delete it, switch to the Select tool (keyboard shortcut V) — click the image to select, drag its body to move, drag the corner handles to resize (hold Shift for free aspect ratio), and press Delete to remove it. You can paste and arrange several images side-by-side to build a lesson, then switch back to the pen to annotate. Everything's saved with your session and included in PNG exports.
Click the Licensed button in the top-right of the toolbar of any activated install — the modal shows your key with a Copy Key button. Paste it on the new machine's License screen. The license covers up to 3 of your personal computers.
InfinitiCanvas is built for stylus input on Windows desktops and laptops. It works smoothly with Wacom, Huion, XP-Pen, Surface Pen, and any tablet that emulates a pen on Windows.
Your license key is tied to you, not your hardware. Just paste the same key on the new machine — you can copy it out of the Licensed modal on any working install. The license covers up to 3 of your personal computers.
Because the full app is free for 14 days with every feature unlocked, purchases are non-refundable once made — you've already had two weeks to decide whether it fits how you teach, on your own hardware, with your own lessons. If the trial didn't convince you, please don't buy. If it did, thank you, and enjoy the licence forever. Genuine exceptions (billing errors, wrong product bought by mistake, technical issues that prevented you from using the trial fairly) are always handled personally — email hello@infiniticanvas.com and we'll sort it out.
The Windows version is shipping today. Mac and Linux builds are in progress — your license key will work on those when they launch, no extra charge.
Email hello@infiniticanvas.com. You'll hear back from a human (the developer) within a day or two.
