I got tired of losing my place while learning with Claude, so I built SubChat. Here's the problem: Claude gives a great answer -> One sentence confuses you -> You want to ask a quick follow-up But if you ask in the main chat, the entire conversation moves forward, and now you’re scrolling up and down trying to connect everything again. So I built SubChat. SubChat lets you highlight any part of a Claude answer and ask a focused follow-up in a small side-chat, right there on the page. You can: - highlight a line and click Ask (any page on google, not just claude) - get a streamed answer in a draggable side widget - open multiple independent side-chats -copy answers/code quickly - keep learning without breaking the main thread It runs on your existing Claude session, so there’s no API key to add. No servers, no analytics, no tracking. Basically: side quests for Claude conversations. I built this because AI chats are becoming less like “search” and more like actual learning environments. But the interface is still mostly one long scroll. Would love feedback, especially from people who use Claude for studying, coding, research, or deep dives.
