The extension (it appears in Chrome as Web Capture) captures the page you’re on, and you can add a note to each capture.
Install
Get the folder
Download the extension folder and unzip it somewhere you’ll keep it. Chrome reads it from there, so don’t delete it afterwards.
Open the extensions page
In Chrome, go to chrome://extensions and turn on Developer mode (top right).
Load it
Click Load unpacked and choose the folder.
Pin it
Open the puzzle-piece menu in Chrome’s toolbar and pin Web Capture, so the button is always in reach.
Sign in
The extension doesn’t know Typemark’s address yet, so open its settings and set Server URL to:
https://app.typemark.ai
Then sign in from the extension. The sign-in opens in your browser, so there is no key to paste. The first time, you’re asked to allow the extension once. Access is by invitation; sign in with the address that was invited.
You can disconnect the extension at any time from the connected apps section of your account page.
