Keep what you think.
Find the thread later.

Notations is a notebook for everything worth keeping: ideas, articles, recordings, research, plans, and unfinished thoughts. Find things again, connect what belongs together, work on them with AI, and decide what happens to them.

Start writing

Fast. Offline-ready. Markdown underneath. Yours to take with you.

The Notations home screen: a clean list of notes with folders, tags, and pin, share, and publish status.
Catch it

Put it somewhere you’ll actually find it again.

A thought mid-day. An article worth remembering. A recording from a walk. A project note that isn’t finished yet.

Drop it into Notations without deciding what it will become. Folders and tags are there when they’re useful—they don’t have to be the reason you can find something later.

Ways to capture

Write directly, clip from the web, import Markdown, bring in recordings from Plaud, import from Notion & Obsidian, paste images, or mirror a plain folder of files on your Mac.

Find it again

You remember the idea, not the words.

You don’t have to remember where you put it.

Search for the words you used, or describe what you’re trying to remember. Notations finds the exact note, the related ones, or the idea scattered across several of them.

Search by words when you know them. Search by meaning when you don’t.

Notations running a hybrid semantic-and-keyword search to find notes by meaning, not just matching words.
See the connection

You’ve written about this before. You just don’t know where.

Sometimes the answer isn’t in one note.

Something you wrote last month may explain a decision you’re making today. A pattern may only become visible after you’ve repeated it five times. Ask across the whole notebook—AI reads the connections, not just one chat’s worth of context.

Works with Claude and other MCP-compatible assistants.

Take it somewhere new

This version is better. The old one still matters.

A new version doesn’t have to erase the old one.

Rewrite something. Challenge it. Make a shorter version. Ask AI to synthesize five related notes into a spec. Notations keeps the new thing connected to what it came from.

Keep revisions, alternatives, and derivatives together—without collapsing them into one endlessly edited document.

One note kept as several iterations — Draft, Tightened, Playful, and Social blurb — as tabs across the top of the post.
Keep control

Some notes are ready for someone else.

Keep it to yourself. Share it. Publish it. Take it with you.

Most notes stay private. Some belong with one other person. Some become worth publishing. And none should become inaccessible because you chose the wrong app five years ago.

Private by default. Portable by design.

AI is a tool, not the repository

Your AI doesn’t need to become your notebook.

Chat is great for thinking. It’s a terrible place to keep your thinking. Connect Claude or another compatible assistant to Notations: it can search what you’ve written, read related notes, create something new, and save the result back where it belongs. Change AI tools later. Your notebook stays put.

Your notebook lives on your device too. Reading and writing stay fast and work offline.
Plain Markdown
Your writing stays usable outside Notations—no proprietary format.
Bring your own AI
Use the models and providers you choose. Nothing runs unless you turn it on.
Private by default
Sharing and publishing are explicit decisions, note by note.

Made for people whose notes turn into things.

  • An article becomes research.
  • Research becomes an argument.
  • A meeting becomes a decision.
  • A journal entry becomes a pattern.
  • A rough thought becomes a product spec.
  • A note becomes something worth sharing.

Your thoughts are already connected.
Give them somewhere they can stay that way.
