Your handwriting,
linked.
Obsilide is a handwriting-first notebook for Android. Circle a word you wrote, and it becomes a link to a new note.
One email when the first build is ready. No list, no noise.

How it works
Typing files things away.
Handwriting is where you think.
So Obsilide doesn’t ask you to type your notes back out to make them useful. The link lives on the ink itself — the strokes stay exactly as you drew them.
01
Write
Ink goes down under the nib, not a frame behind it. Rest your hand on the glass — palm rejection handles it.
02
Select a slice
Lasso it, drag along the line, or tap a word. Selection lands on part of a stroke, so it works on cursive.
03
It becomes a link
Tap it later and you’re in a new note. Its cover is the handwriting you selected — nothing to name, nothing to type.
Built for the pen
Fast where it counts.
Front-buffered ink
Wet strokes render straight to the front buffer — the same technique Samsung Notes uses — with motion prediction and full digitizer sampling on top.
Plain files you own
One folder per note: a Markdown file with the links, an ink sidecar with the strokes. Readable in any editor, backed up like anything else.
Canvas that keeps going
Keep writing and the page extends under you. Pinch to zoom in on small handwriting; two fingers to move around.
Palm rejection that trusts the pen
Once the stylus is in play, your hand stops drawing. Pick the pen up and touch scrolls again. The window is yours to tune.
A graph you drew
Links go both ways: every note knows what points at it. Notebooks are covers, not filenames — you recognise your own handwriting faster than any title.
Offline by construction
No account, no telemetry, no sync. Your notes never leave the device — the only request the app can make is a one-time license activation.
Your notes, your disk
No account. Your notes never leave.
Handwriting is the most personal thing you can put in an app. So Obsilide keeps it in plain files on your device and asks for nothing else — one permission, used once, to activate a license if you ever buy one.
- Links live in the Markdown as
[[wiki-links]]— the graph rebuilds from text alone - Saves are atomic and fsynced; a killed app never leaves a half-written page
- An unreadable file is quarantined, never deleted — handwriting doesn’t get thrown away quietly
