About Contextual

A local-first AI context engine with semantic search, temporal recall, and on-device indexing. A context engine that runs entirely on your machine, indexed, queryable, and aware of how your repository changed over time. ▸ nexus_search (query="why did we switch the webhook signer to HMAC-SHA512?", intent="mixed") . Contextual is engineered around the smallest set of ideas that make a codebase searchable through time, on a single laptop, without sending anything out. Ask "what did this file mean last quarter?" and walk the answer backwards.
