Comparison
Athena Index vs Webcite
Webcite checks whether a statement is supported right now. Athena checks whether a person has been worth believing over years. One is verification, the other is a track record.
Athena Index
Longitudinal credibility. Scores a named person across their full claim history, including what they did after being wrong.
Webcite
Single-claim verification. A verification API that checks LLM output against sources and returns citations with confidence scores.
The difference in one paragraph
Webcite answers is this statement supported. That is a per-claim question with a per-claim answer, and it is the right tool if you are grounding model output in citations at request time.
Athena answers a different question: given everything this person has claimed, how much weight should their next claim carry. That requires a history, not a lookup, which is why the score moves on outcome alignment, specificity, consistency, transparency, accountability and calibration rather than on whether one sentence checks out.
The accountability pillar is the clearest split. Athena records what happened after a claim failed, including deletions, quiet edits and corrections. A verification API has no view of that, because by then the claim is no longer the thing being checked.

When Webcite is the better choice
If you are building an AI application and need citations attached to generated text at request time, a verification API is the correct primitive and Athena is not a substitute. Athena is for diligence on people, not for grounding model output.
Common questions
Can Athena Index verify a single claim like Webcite does?
Not as a request-time API for arbitrary text. Athena verifies claims it has already extracted and indexed from tracked sources, and checks the outcome once the claim's deadline has passed rather than immediately.
Why does Athena wait for a deadline instead of scoring right away?
A forecast is not right or wrong until the window it named has closed. Scoring it earlier would measure how plausible it sounds rather than what happened, which is the failure mode the product exists to correct.
Could a team use both?
Yes, and they solve adjacent problems. Webcite grounds generated text in citations. Athena tells you whether the human who made a claim has a record of standing behind their claims.
How much does Athena Index cost?
The public index is free with no account. The Claim Ledger Pilot is scoped and priced per engagement. See the pricing page for what is in each tier.
