I kept running into this annoying problem:I’d remember a really useful answer, but not where it was.ChatGPT? Claude? Gemini? No idea. So I’d end up digging through all of them or just rewriting the prompt.Built this to fix that.It’s a Chrome extension that indexes chats locally and lets you search across them all in one place. Once it’s indexed, search is basically instant.Still early. UIs change and break things sometimes, so it’s a bit fragile in places.Curious if other people have the same issue or if it’s just me jumping between tools too much.
