Sidekick AI wót woojooin

Ask AI about the page you're viewing—right in the Firefox sidebar.

Sidekick AI keeps up with the page in your active tab. Ask questions like "Summarize this article" or "What does this page say about X?" without copying and pasting text yourself.

Two ways to chat

Web mode
Embed the official web UIs for ChatGPT, Claude, Gemini, and Microsoft Copilot in the sidebar. Sign in with your existing account—no API key required.

• Click Summarize page to copy the current page context to your clipboard
• Paste it into the chat input on the service you choose

API mode (advanced)
Bring your own API key for OpenAI, Google Gemini, Anthropic, or Groq.
- Requests go directly to the provider over HTTPS
- Enables the AI to search the live web and provide up-to-date responses
- Your key and settings stay on your device
- Page title, URL, and extracted body text are included automatically when you send a message

Sidekick AI uses a [BYOK] model.
