About deja-vu

Your agents already solved this. deja finds it.Memory tools start empty and record forward. deja starts full: it indexes the sessions your coding agents already wrote to disk — months of history from before you installed it — searches 3.3 GB in 1 ms, serves it back to any agent over MCP, and moves with you between machines over SSH. One zero-dependency binary, fully local. 84.9% hit@1 on LongMemEval-S retrieval — no LLM, no embeddings, no API key.
