> Search that self-improves. Fast, accurate product and file search. Offload tuning without losing control. Always in sync with your sources.
Captain is one platform: a managed file search API (v3), the `captain_eval` MCP tool (which writes evals from your own files and tunes retrieval toward the accuracy or latency target you set), Captain Sync for event-driven bucket sync (S3, R2, GCS, Supabase, Backblaze), an open source MCP server, and opt-in PII masking at index time. Free tier: 500 indexing credits a month, then $0.02 a credit. Docs at https://docs.captain.dev. Support: humans@captain.dev. Full site text: https://captain.dev/llms-full.txt.
