Claim-Level Verification

Green means verified. Amber means caution. Red means flagged. Every claim, every time.

THE PIPELINE

Three Stages. Zero Guesswork.

After generation, every claim passes through extraction, resolution, and verification.

Stage 1

Claim Extraction

Every factual assertion is identified and isolated from the generated report.

Stage 2

Source Resolution

Each claim is matched to its cited source. The actual text is retrieved.

Stage 3

Three-Check Verification

Relevance. Support. Faithfulness. Three checks per claim, every time.

THE THREE CHECKS

R · S · F

Relevance. Support. Faithfulness. Three questions every claim must answer.

R — Relevance
Is this source actually about the claim?

Filters out sources that mention related topics but don't address the specific assertion.

S — Support
Does the source support this claim?

Determines whether the source text actually backs up what the report says.

F — Faithfulness
Does the claim accurately represent the source?

Catches exaggeration, misquotation, and subtle distortion.
