Quad by Quad Labs Technologies

Quad brings AI chat into your Firefox sidebar. Ask questions about the page you are reading, summarize articles, pull out key points, explain difficult text, or draft a reply without leaving the tab.

Choose how much intelligence Smart brings to each message. Sign in to use your Quad account and plan. Browser chats are private by default; you can choose to save them to your Quad chats.

The optional browser Agent can carry out supported browser tasks and asks before consequential actions. Agent requires Pro or above. A Quad account and available credits are required for AI features; free and paid plans are available.

Page content is shared with Quad only when requested. Page access is optional. Quad Home, the new-tab extension, is available separately.
