Threadlane tekijä Threadlane

Keep your feedback beside the passage it refers to, and prepare follow-up messages while an AI response is still arriving.

Threadlane works inside ChatGPT, Claude, and Gemini:

• Highlight part of an assistant response and add an inline note.
• Insert a revision prompt built from your notes into the native composer. Saved notes remain until you delete them.
• Queue text follow-ups while a response is running. They send in order after the previous response finishes and the composer is ready.
• Drag to reorder, edit a message in its original position, delete it, or pause and resume the queue.
• Use Send now to stop the current response, if necessary, and send a selected queued message.
• Share saved notes and queue state between tabs of the same conversation in your Firefox profile.

Notes and queues are stored locally in the extension, with no publisher analytics, advertising, telemetry, or cloud storage. Queued messages and annotations you submit go to the AI provider through its normal composer. They do not sync between browsers, profiles, or devices.

Automatic sending requires a visible conversation tab with an empty, ready composer. Existing drafts and attachments hold delivery in that tab. The queue supports text only. If a send cannot be confirmed, Threadlane holds the queue for your review; check the chat before retrying.

Requires desktop Firefox 140 or later and access to the supported provider’s normal chat interface. Private browsing is not supported. Threadlane is free and does not include an AI-provider subscription. This is an early beta; provider website changes may affect compatibility.
