Build a local-first browser extension that records AI conversations, creates structured project memories, tracks usage limits, and exports compressed context bundles. The first product surface can be a sidebar inside supported AI chat sites with buttons for save memory, resume elsewhere, compress context, export Markdown/PDF^?, and queue next prompts after reset. Start with Claude, ChatGPT, and Gemini support, using DOM capture plus local browser storage before adding team sync or paid cloud features.

AI chat is becoming a daily work environment, but model limits, fragmented tools, and long-running projects make continuity painful. Multiple recent extensions gaining organic traction suggest the buyer workflow is urgent and under-served by the AI platforms themselves.
