FOIA search is fragmented and keyword-only. DeclassDB unifies seven federal archives — CIA CREST, FBI Vault, NSA, State, NARA, DoD, NSArchive — and adds AI semantic search, so you can find what you mean, not just what you typed.
AI semantic search
Find by meaning across 309,708 CREST documents (1.05M pages, full-text). The embedding model runs in your browser — no cloud round-trip. Pro & Researcher.
One query, every agency
Unified, blended, de-duplicated across seven federal sources. CIA / FBI / State always free; NSA / NARA / DoD / NSArchive unlocked on Pro.
Privacy-first by design
Vectors, AI summaries, and entity extraction all run on your device. No cloud, no search logs, no third-party trackers. Air-gappable for federal use.
