Install the Misir extension

Misir captures what you read and ask AI, and works out which of your decisions it belongs to — on your machine. The extension is how it sees any of that.

Download for Chrome — 7.3 MB

Chrome, Edge, Brave, or any Chromium browser.

  1. 1

    Download and unzip

    Unzip it somewhere permanent — Chrome loads the extension from this folder every time it starts, so don't delete it or use a temp folder.

  2. 2

    Open chrome://extensions

    Paste chrome://extensions into your address bar and press Enter. Links can't open it for you — Chrome blocks that.

  3. 3

    Turn on Developer mode

    Top-right of that page. Unpacked extensions only load with it on.

  4. 4

    Click "Load unpacked"

    Top-left. Select the folder you unzipped — the one containing manifest.json.

  5. 5

    Sign in, then pin it

    Sign in to Misir in this browser — the extension reads your session from the site. Then pin it from the puzzle-piece menu so it's one click away.

First capture is slow.The extension downloads its ~140 MB language model once, from Hugging Face, and caches it in your browser. That model is what reads pages on your device — nothing you don't save is ever uploaded.

Updates are manual for now.While we're unlisted, Chrome won't auto-update it. We'll tell you when there's a new build — download again and hit Reload on the extensions page.

"Disable developer mode extensions"? Chrome warns about anything not installed from its store. Dismiss it — the extension keeps working.

Capture is off until you turn it on, per purpose. See how we handle your data.
