The Verifier: An Evidence‑First Research Assistant for Public Claims

Description and use

The Verifier lets users verify public claims by displaying supporting and contradicting evidence, comparing dates, and requiring human approval before saving results.

Problem

AI can produce answers that were once correct but are now outdated, leading to misinformation in reports and decisions.

Outcome

The Verifier enables users to see both supporting and contradicting evidence, compare dates, and make informed decisions, reducing the risk of relying on outdated AI answers.

Workflow

• 1. User enters a claim (e.g., "Brian Niccol is the CEO of Starbucks").
• 2. The system searches for evidence supporting the claim.
• 3. Simultaneously, it searches for credible evidence contradicting the claim.
• 4. It extracts machine‑readable dates from each source and normalizes them to UTC.
• 5. Sources are displayed in separate lanes with role, URL, statement, and date information.
• 6. The system compares dates to determine which evidence is newer.
• 7. It presents a transparent explanation of how the conclusion was reached.
• 8. The user reviews the evidence and decides whether to approve saving the dossier.
• 9. Upon approval, the server stores the dossier and allows export; otherwise, nothing is saved.

Evidence

The Verifier extracts machine-readable dates from every source. It records which metadata field was used, preserves the original value, and normalizes the date to UTC.

Source

The system can compare evidence deterministically. It does not choose a source because it sounds more confident.

Source

After completing the investigation, The Verifier does not automatically store the result. It asks the user for approval.
