Temporary personal whiteboard
A temporary whiteboard without the meeting software
Use TempCanvas for a quick explanation, lesson, or diagram without creating an account or a permanent cloud project. Work privately in your browser, then choose a PNG export or a live audience when you need to share.
Explain an idea quickly
Draw a process, map a relationship, or work through a calculation during a call. Pens, shapes, text, and image paste cover common one-person whiteboard tasks.
A local canvas you can recover
Ordinary drawing is saved in this browser for recovery after a refresh. It is not automatically sent to a presentation room. Export a PNG for a lasting copy; browser storage can be cleared, so local recovery is not a backup.
A temporary session for your audience
Live presentations (Beta) give up to 100 viewers a read-only view for up to two hours. Share an 8-character access code, invitation link, or QR code. Automatic admission is on by default; turn it off if you want to approve viewers manually. Keep the presenter page open while presenting.
Share the whole whiteboard intentionally
Starting a presentation sends the entire canvas, including content outside the current screen, through an encrypted Cloudflare relay. Viewers follow your center and zoom by default, with free viewing available at your choice. The relay does not persist the canvas, and there is no session replay.
Works with the input you have
Use a mouse, trackpad, touch screen, or compatible stylus. The same canvas adapts to desktop, tablet, and mobile screens.
Does a temporary whiteboard disappear when I refresh?
The current canvas is saved locally for recovery in the same browser. Download a PNG if you need a copy you can keep independently of browser storage.
Can I invite people without creating an account?
Yes. Live presentations (Beta) use an access code, invitation link, or QR code. The presenter edits; viewers watch without an account.
How long does a live whiteboard session last?
A session supports up to 100 viewers and expires after two hours. It also ends when you stop presenting; keep the presenter page open during the session.
