Tangent – Threaded Chat for ChatGPT & Claude

The Chrome extension that adds parallel threads and split-screen chat to ChatGPT and Claude.

You're in a ChatGPT or Claude conversation and it finally clicks — the AI just gave you the clearest explanation you've ever read on a topic. Then you have a follow-up question. You type it. The thread grows. You scroll back up to re-read the original. Then another question. More scrolling. More noise. The insight you were building on is now buried, and your concentration is gone.

Tangent is the ChatGPT and Claude extension that solves this. Open a parallel chat thread — right next to your main conversation — without leaving the page, opening a new tab, or losing your place.

What Tangent gives you on ChatGPT and Claude:

Branch off from any message. Run parallel conversations simultaneously. Keep your main thread clean while you explore sub-topics, chase rabbit holes, and ask follow-up questions in dedicated side threads. When you're done, close the thread or minimize it to a tab and jump right back — the original text flashes to remind you exactly where you branched off.
