# Use the browser extension

> Clip the page you are reading without opening a second workflow.

The Tuck browser extension is a capture tool, not a second Tuck app.

It supports Chromium browsers such as Chrome, Edge, Arc, and Brave, plus Firefox.

## Clip a page

Open the extension or press `Alt+Shift+T`.

If text is selected, Tuck captures the selection and the page URL. If nothing is selected, it captures the URL.

Before you tuck it, you can add a brain, tags, people, a todo, or a calendar date.

## If the page already exists in Tuck

The extension can show thoughts that already mention the same page so you can open them instead of creating a duplicate.

## When the vault is locked

Keep Tuck unlocked in a browser tab when you want clips sealed immediately. If Tuck is locked or closed, the extension queues the clip locally until Tuck is available again.

The badge shows how many clips are waiting.
