Map Which Sources Actually Back Which Claim — Free
List the claims in your draft and mark which of your sources support each one, so the unsupported claim shows up before a marker finds it. The free tier is the whole card: every field, every state, and the state link. Nothing is withheld behind the optional one-time tier.

Data note: Everything is computed in this browser tab. Nothing you type is uploaded, and nothing is stored on our servers. Redact names and identifying details before you paste anything sensitive, and check the output against the named source before you act on it.
2 · Read the coverage grid
GratisAI mapped my draft's claims against the sources behind them — the unsupported rows were boxed before submission.
Boundary: This maps your own claims against your own sources; it does not check whether a source is reliable, current or correctly cited. Follow your institution's referencing rules and read what you cite.
Free core · $4 one-time
Every claim, the source count and the unsupported-row check stay free. The one-time tier adds the printable matrix plus the saved drafts behind it.
