Yes. Sketching, designing and playing are free and need no account. Saving to your account uses credits, and you get free ones every day you sign in.

Do I need to install anything?

No. JotJam runs in the browser — Chrome, Safari, Edge or Firefox — on a phone, a tablet or a computer.

Does it work on an iPad with Apple Pencil?

Yes. The sketch pad reads pencil pressure, and once you draw with the pencil, your fingers only move and zoom the page, so you can rest your palm on the screen.

Which files can I download?

Sketches as PNG. Designs as PNG and SVG, plus a scale PDF or a DXF for a few credits. Riffs as MIDI and WAV, plus sheet music (PDF or MusicXML) for a few credits. Symbols from the library as SVG and PNG, free and without signing in.

Architecture and design students, designers, and anyone who sketches or plays music for fun and wants to catch an idea before it's gone.

How saving works

Everything is free to use. While you work, your latest changes are kept as a draft in this browser. When something is worth keeping, sign in with Google and save it to your account — it's then there on every phone, tablet and computer you sign in on.

Saving uses a couple of credits, and you get free credits every day you sign in. Only saved work can be downloaded.
