Overview

FactGuard checks claims, headlines, or URLs and returns a verdict with reasoning and cited sources. It offers Quick, Thorough, and Private verification modes, with a confidence score from 0 to 100 and analysis of framing and potential bias. The web app limits submissions to 1,000 characters; its free tier uses Quick mode and displays the 30 most recent checks. The free plan costs 0.00 USD per free, billed forever, and includes three checks per day. Pro includes unlimited checks and history, Thorough verification, all modes, shareable verdict cards, and bulk export, but its listed plans are marked coming soon. FactGuard also describes an early-access MCP server and a Fact-Check API with a stated free tier of 100 calls per day; API access and team pricing are under development. The privacy policy says claims sent to the backend are not stored per user on FactGuard's servers. Optional on-device verification is not transmitted to FactGuard or third-party processing providers. FactGuard cautions that automated verdicts can be inaccurate, incomplete, or out of date and advises checking cited sources.
