Gemini Executive Synthesis

LLMnesia, a Chrome extension for local, cross-platform search of LLM chats (ChatGPT, Claude, Gemini).

Technical Positioning

Solves the problem of losing track of useful answers across multiple LLM platforms by providing a unified, instant, local search capability.

SaaS Insight & Market Implications

The rapid adoption of multiple LLM platforms (ChatGPT, Claude, Gemini) creates a significant user pain point: fragmented knowledge recall. LLMnesia directly addresses this by offering a local, instant, cross-platform search solution for chat histories via a Chrome extension. This product capitalizes on the growing reliance on AI assistants for information, highlighting a critical need for effective knowledge management within the LLM ecosystem. The "fragile" nature due to changing UIs underscores the inherent instability of building on rapidly evolving third-party platforms. This solution indicates a nascent market for tools that aggregate and organize AI-generated content, enhancing user productivity and reducing redundant effort.

Show HN: LLMnesia – search across ChatGPT, Claude, Gemini chats locally

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.
