Every quote, checked against the source

Deterministic, not statistical

Verification is a sliding-window match against the source text with a high similarity threshold. There's no model deciding whether a quote is "close enough" — either the words appear in the source or they don't. Mismatches get removed and the model is asked to retry against what it actually has.

Refuses to fabricate

If the model can't find supporting text in the source, the claim doesn't ship. That refusal step is what makes this safer than a general AI assistant for work that has to be cited.

Verified citations FAQ

What counts as a verified quote?

Text that closely matches a passage in the cited source, ignoring trivial whitespace and quote-style differences. The threshold is calibrated to accept near-exact matches and reject paraphrases.

What happens to unverified text?

Quotes that fail verification are removed before the answer is shown. The model is then re-prompted to produce a verifiable claim or to acknowledge that the answer isn't in the source.

Does verification slow things down?

Not meaningfully. The verification step runs against the retrieved passages, not the whole document, and is fast string work.

What does it cost?

Verified citations are part of every plan, including Free. See pricing.
