Addendo
Addendo for your browser

Keep the good parts of the web.

The Addendo plugin puts a small button beside your address bar. Click it once and the page you are viewing is saved to your library—or straight into a collection you choose.

What is a plugin?

A shortcut between your browser and Addendo.

A browser plugin is a tiny helper you add to your browser. Addendo's does one focused job: it sends the address and title of the current page to your account when you ask it to. It does not watch the pages you visit.

Quiet by design

It waits for you.

  • The plugin receives the current URL and title only when you click its button.
  • Its account token can save links but cannot read your password or browse your Addendo account.
  • Collection names are loaded only when you connect or press Refresh—not as pages load.

Save the next thing worth keeping.

Create your Addendo library, then connect the browser you use every day.
