Public knowledge experience

Provenance-backed AI history

Intercal is an open, provenance-backed temporal knowledge substrate for agents and LLM apps. It turns source documents into claims, resolved entities, typed temporal relationships, and append-only bitemporal fact versions. Use it to ask what changed after a cutoff date, verify a claim as of a date, inspect provenance, and connect agents over same-origin MCP and REST. Public coverage is bounded by the reviewed AI-history corpus gates and every surfaced fact must cite evidence or show an explicit coverage state.

Cited substrate

Public coverage stays bounded by the reviewed AI-history corpus gates. Every surfaced fact cites evidence or shows an explicit coverage state.

What the public surface answers

Cutoff deltas: Ask what changed about a topic after a date with cited changed claims.
Claim verification: Check whether a claim was supported or contradicted as of a date.
Provenance: Public pages cite source-document paths or display explicit coverage states.
