Summary

FactGuard checks claims, headlines, statements, and URLs, then returns a verdict with reasoning and cited sources. Its verdicts include a confidence score from 0 to 100, and the service says it surfaces framing and potential bias. Users can choose Quick, Thorough, or Private verification modes. The free web tier uses Quick mode, limits submitted claims to 1,000 characters, and provides three checks per day; its history shows the 30 most recent checks. FactGuard supports text and images as well as written claims. Pro plans are listed as coming soon: the annual option is 36.99 USD per year, billed yearly, equivalent to $3.08/mo, and includes unlimited checks and history, all modes, shareable verdict cards, and bulk export. Pro image checks are offered; provenance, metadata, and first-seen checks stay on-device. FactGuard also describes an early-access MCP server and a Fact-Check API with a stated free tier of 100 calls per day. Its privacy policy says backend submissions are not stored per user on FactGuard’s servers; optional on-device verification is not transmitted to FactGuard or third-party processing providers.
