About Claude Session Key

This extension copies the session key of your claude.ai login to the clipboard, so you can paste it into any tool that needs it. It was written as a companion for Claude Usage Widget, a Windows app that shows your Claude usage limits on the desktop without opening claude.ai to check. The widget's setup screen asks for exactly this key. How to use it with the widget: 1. Log in to claude.ai 2. Click the extension icon 3. Click "Copy to Clipboard" 4. Paste the key into the widget's setup screen The key is a cookie. The extension reads it on your machine and writes it to your clipboard when you click the button; it is sent nowhere. No telemetry, no remote code.
