FaceFact
A Chrome extension that adds AI-powered fact-checking to Facebook posts. One click runs an agentic pipeline that summarizes the post, extracts the factual claims, searches the web for evidence, and returns a verdict with sources — all streamed in real time.
Features
- One-click "Verify" button injected next to every Facebook post
- Real-time streaming pipeline: summarize → categorize → extract claims → verify
- Claim-by-claim verdicts with confidence scores and source links
- Smart skipping for opinions, humor, and personal posts so fact-checks are not wasted
- Evidence gathered via live web search — no stale or cherry-picked sources
- Results cached locally for 24 hours so re-checks are instant
- Works on Vietnamese and English posts
- Open source — Chrome Manifest V3, shadow-DOM-isolated UI
How It Works
- Summarize — Condenses the post to its core message.
- Categorize — Classifies as news, claim, opinion, personal, humor, or promotion — non-verifiable categories short-circuit the pipeline.
- Extract Claims — Pulls individual factual claims and generates targeted search queries.
- Verify — Searches the web and evaluates each claim against evidence, returning a verdict with sources.
