ReticulOS is a desktop notes app that keeps what you save from any app in one place, then answers your questions about it and shows you exactly where each answer came from.

  • Free to use
  • Encrypted on your computer
  • Mac, Linux and Windows

Your life is spread across a dozen apps.

ReticulOS keeps it in one.

How ReticulOS works

  1. 1

    Save it.

    Anything, from any app. One shortcut.
  2. 2

    Ask it.

    In your own words.
  3. 3

    Get the answer.

    With a link to where it came from.

Nobody needs another app. You need one that stays with you, keeps what matters, and works with every other app you use.

That's the idea behind ReticulOS.

One app for everything you keep.

Notes, links, pictures, PDFs and recordings, in collections you shape.

Notes that take shape

Write the way you think. Lists, to‑dos and headings tidy themselves as you type.

A place for every part of life

A trip, a thesis, a home. Everything lands where it belongs.

PDFs, page by page

Ask “when is rent due?” and get the page of the lease that says so.Pro

Recordings in one click

Record a lecture or a call. Find the moment later by describing it.Pro

A day book that carries forward

Didn’t finish something yesterday? Carry it to today with one click.

A vault for passwords

Locked with its own password. Never searched, never sent to any AI.

Works with the AI you already use.

Connect Claude, Cursor or any app that supports MCP, free. They can read what you've saved, and they only add to it when you say yes. Or sign in with ChatGPT and Ret answers from the plan you already pay for. Here's how to set it up.

Coming from NotebookLM, Obsidian, Notion or a clipboard manager? See how they compare.

Yours, and only yours.

Locked on your computer.

What you save is kept on your own machine, encrypted.

Search works offline.

Finding things runs on your computer, so it works on a plane, on a train, or when the Wi-Fi gives up.

Take it all with you.

Export everything to ordinary files whenever you like. Leaving should never be hard.

Nothing changes without a yes.

AI apps can suggest new notes. Nothing is added or edited until you approve it.

Exactly where your notes live, and what can leave your computer: how your notes stay private.

Or watch the whole story in a minute.

Saving and asking are in the beta today. Some features shown, like filling in forms, are coming soon.

Your work lives everywhere. Tabs, files, chats, code.

ReticulOS keeps the thread. Select a line, press one shortcut, and it's captured where you're working.

Coming next: that sign-up form asking for everything? Filled in one click, from details you've already saved.

The right résumé. The right link. Prepared for you to check, before anything is sent.

ReticulOS connects to your coding agent, so the latest updates land right in the app.

Ask for a reply, and it's written for you, ready to send.

And today, AI Mode turns what you've saved into a brief, with citations back to your notes.

Now think of every form you fill, every file you hunt for, every reply you owe.

What will you use it for?

ReticulOS. Your computer, with context.
