The best ideas live in the margins.

Margin is where your best ideas go — quick, quiet, always within reach. A note-taking companion that lives alongside everything you do.

Three seconds. That's all.

No folders, no friction. Just you and your thoughts.

01

Open Margin

Press ⌘ + M from anywhere. The margin panel slides in beside what you're doing — no context switch required.

02

Type your thought

No title required. A thought, a quote, a reminder — just write. Tags and links are there when you need them.

03

Close and move on

Hit Esc. It's saved. Your margin stays with you, ready for the next thought. Zero ceremony.

Designed for thought.

Everything about Margin is built to capture ideas — not manage them.

Quick Capture

Open Margin from anywhere with a shortcut. Type your thought, tag it, and move on. No folders, no friction.

Side-by-Side

A panel, not a page. Margin sits alongside your browser, your editor, your docs — always there when inspiration strikes.

Everywhere You Are

Desktop, mobile, tablet — your notes follow you. Start a thought on your phone, finish it on your laptop. It just works.

Private by Design

End-to-end encrypted, zero-knowledge architecture. Your thoughts belong to you — full stop.

🛡️

Your thoughts belong to you.

Margin is built on a zero-knowledge architecture with end-to-end encryption. We cannot read your notes, and neither can anyone else. Privacy isn't a feature — it's the foundation.
