Ideas deserve rough edges.

Smudge is a sketchbook app for unfinished thinking — scribble, tape things down, cross stuff out. No gradients, no gloss, just honest progress.

~ yes, it's really supposed to look like this ~

What's in the tin

Three honest tools and one very forgiving eraser. Everything looks hand-made, because a human made it.

Sketchy by design

Wobbly borders, torn tape and paper grain baked right in. Your drafts look like drafts — because they are.

Tape everything down

Pin fragments, screenshots and half-thoughts onto one messy board. Nothing has to be finished to be useful.

Keep the ugly drafts

Every version stays, smudges included. Look back at where an idea came from, not just where it landed.

How it works

Three steps. Zero cleanup crew.

  1. Scribble

    Open a page and make a mess. No templates, no onboarding parade.

  2. Smudge

    Rearrange, tape over, cross out. Smudge never tidies up behind you.

  3. Ship it rough

    Share the unfinished thing. Feedback lands on real work, not on polish.

Notes from the margin

I stopped agonizing over blank canvases. Smudge gives you permission to be bad on purpose — and somehow that's freeing.
Ren Okafor — illustrator
Our best idea this year started as a taped-up napkin scan in here. Still ugly. Still shipped.
Mara Voss — product lead
It feels like my desk, not like software. My zine layouts have never been this happily disorganized.

Questions, answered roughly

Yes. Every wobble, tape mark and coffee ring is on purpose. We think a tool should look like the messy process it holds, not like a magazine ad.
