Personal Knowledge Base from LLM Conversations

A system that automatically converts your LLM chat histories and markdown notes into a searchable, browsable knowledge base. Users can organize insights from Claude, ChatGPT, etc. into a personal wiki they can query and build upon over time.

LLM usage has exploded since late 2022, and power users now have years of chat history they can't effectively search or reuse — that pain is real and growing. Notion AI and Obsidian with various plugins are the closest substitutes, but neither is purpose-built around ingesting and structuring LLM conversation exports specifically. At $200–1k/month, this lives in the "useful side project" tier rather than a fundable business, which is fine if built lean, but it implies a small addressable niche of productivity-obsessed users willing to pay for something they could approximate with free tools. The biggest risk is that OpenAI, Anthropic, and Google simply ship native memory and search features into their own products, which they're already doing, making the core value prop obsolete before meaningful traction is reached.
