WhyTho
Open the app

Install the extension

Two minutes. It puts a WhyTho button on your browser toolbar, so any page is one click from being annotated.

Download whytho-extension.zip

Works in Chrome, Edge, Brave and Arc. Firefox and Safari need their own builds, so use the bookmarklet there.

Install it

  1. Download the file above, then double-click it to unzip. You get a folder called whytho-extension.
  2. Move that folder somewhere permanent, like your Documents. Chrome reads it from disk every time it starts, so it cannot live in a Downloads folder you clear out.
  3. Open a new tab and go to chrome://extensions. In Edge use edge://extensions, in Brave brave://extensions.
  4. Turn on Developer mode with the switch in the top right.
  5. Click Load unpacked and choose the folder. Pick the folder itself, not the zip, and not a file inside it.
  6. Click the puzzle piece in your toolbar and pin WhyTho so the icon stays visible.

Connect your account

  1. Open whytho.jakelabate.com and sign in, with GitHub or an email link.
  2. Go to Setup. The first card will say the extension is installed.
  3. Press Connect this account. It hands the extension your annotator token, and nothing else.

Until you do that, the extension still works, but notes stay in that browser instead of saving to your account.
