FactGuard

FactGuard is an automatic claim-checking service for readers who want a reasoned verdict, citations and context about framing. It suits people checking short claims and headlines; its free tier is a useful starting point, though daily limits and Pro features constrain sustained use.

Overview

FactGuard checks claims, headlines and URLs and returns a verdict with reasoning and web citations. A calibrated confidence score from 0 to 100 and analysis of potential bias add context to the result, but neither replaces examining the cited evidence. The service cautions that automated verdicts may be inaccurate, incomplete or out of date.

The web app caps submitted claims at 1,000 characters, and free web checks use Quick mode. That makes it better suited to focused questions than lengthy material. Images are supported, but image checks are a Pro feature.

Key features

Modes, citations and context

Quick, Thorough and Private modes give users different verification options. Free users get Quick checks and Private on-device mode; Pro is described as including Thorough verification and all modes. Citations make it possible to follow the reasoning back to web sources, while bias analysis can prompt closer attention to how a claim is framed.

Privacy and security

Submitted claims are sent to FactGuard’s backend and, according to its privacy policy, are not stored per user on its servers. Optional on-device verification is not transmitted to FactGuard or third-party processing providers, making it the more privacy-conscious choice for users who want to avoid sending a check off-device. The policy also cites TLS in transit, Firebase App Check, cryptographic nonces for Sign in with Apple and password hashing by its authentication provider.

History, images and integrations

The free web plan shows the 30 most recent checks; Pro is described as offering unlimited history and bulk export. Pro image checks include provenance, metadata and first-seen checks that stay on-device. FactGuard also describes an early-access MCP server for Claude, Cursor or another MCP host, and a Fact-Check API with 100 calls per day on its stated free tier. API access and team pricing are under development on the newsroom page, so teams needing those offerings now should look elsewhere. Email support typically responds within 1–2 business days.

Pricing

The free plan is the sensible fit for occasional checks: it costs nothing but caps use at three checks a day and limits history. Pro’s unlimited checks and deeper modes target regular users, while its annual term lowers the stated monthly equivalent compared with paying monthly. Both paid plans are marked coming soon, so they are not an immediate upgrade option.

Platforms

FactGuard is available on web and iOS, with API access also listed. Its web app has the 1,000-character claim cap; the product also describes the API’s free tier as 100 calls per day.

Who it's for

FactGuard is a good fit for individuals who want a quick, cited check of a short claim and appreciate a confidence score, framing analysis or a private on-device option. Researchers who need frequent checks, complete history or image verification have reasons to consider Pro, but should note that the paid plans are coming soon. It is not a substitute for checking sources, especially when a verdict matters.

Pros and cons

• Pro: Verdict reasoning, web citations, confidence scoring and bias analysis give readers several useful ways to assess a claim.
• Pro: Private on-device verification is not transmitted to FactGuard or third-party processing providers.
• Con: Free use is limited to three daily checks, Quick mode and the 30 most recent web checks; the 1,000-character web cap also rules out longer submissions.
• Con: Image checking and the unlimited history and bulk export described for Pro require a paid plan that is marked coming soon.
• Con: Automated verdicts can be inaccurate, incomplete or out of date, so readers must review citations rather than treat a score as a guarantee.

Alternatives

For a broader category comparison, see AI Fact-Checking Tools.

• VerumVerify is worth comparing if Android support or a weekly rather than daily free-check allowance better suits your routine; its free plan includes three checks per week.
• Crowdee is the alternative to consider for a self-hosted option or a focused image-verification workflow; its free plan allows one image verification per IP per 24 hours.
• FAXTR is worth considering for API use: its free plan includes 1,000 API calls per month and community support.
• Trusul is another web-based option, with a free plan for limited daily text and URL analyses and limited saved history.
• Avancer Document Fact-Checker may suit users seeking image, audio and document checks, with one free scan and no credit card required.
• Factward is a web and extension alternative whose free plan allows two verifications per day and includes URL and PDF checks.
• Groundery is another option to compare.
• Veritier is another option to compare.

Verdict

Choose FactGuard if you want short, citation-backed checks with confidence and framing context, and especially if private on-device verification matters. Its free tier covers occasional use, but the daily cap is restrictive for regular research, and readers who need dependable long-term access to Pro features should look elsewhere until those plans are available.
