— A small, opinionated notes app —

Quiet notes for thinking out loud.

Markdown by default, encrypted before it leaves your laptop, and finally — no AI button you didn't ask for. Margin is a notes app for people who already know how they want to write.

Quarterly review prep

#ops#q2

Three things to surface for Friday:

1. Migration milestones — keep it short, link the dashboard.

2. The hiring lag and what we did about it.

3. One unresolved question to put to the room.

Don't over-deck this. The room reads slides faster than I can present them.

Built for people
who don't like apps that try too hard.

Six things Margin does well. Most of the others, we don't do at all — on purpose.

01 · Local-first

Your laptop is the source of truth

Notes live as plain Markdown files in a folder you choose. Sync if you want; don't if you don't.

02 · End-to-end

Encrypted before it leaves you

If you turn on sync, everything is encrypted with your passphrase. We can't read your notes. Neither can the cloud.

03 · Markdown

Real Markdown, not Markdown-ish

CommonMark plus footnotes, tables, callouts, and math. Renders in any other editor without surprise.

04 · Search

Search that just works

Full-text, fuzzy, instant. Across folders, tags, and bodies. No indexing screen on launch.

05 · Quiet

No AI you didn't ask for

No sidebar suggestions. No autocomplete that finishes your thought wrong. The app shuts up and lets you write.

06 · Portable

One folder, three platforms

Native macOS, native Linux, web app for Windows. Same files, no migration step.

Pricing without funnel tricks.

Free does what 90% of people need. Pay only if you want the cloud sync.
