FactGuard

Overview

FactGuard automatically detects claims and returns verdicts supported by links to web sources. A 0–100 confidence score and analysis of framing and potential bias offer useful context, but neither guarantees a correct conclusion: FactGuard cautions that automated results may be inaccurate, incomplete or out of date. Readers should assess the cited evidence before relying on a verdict.

The web app caps submitted claims at 1,000 characters, a practical fit for short statements rather than lengthy material. Images are supported, but image checks are a Pro feature. Free web checks use Quick mode.

Key features

Checks with context

Quick, Thorough and Private modes give users different approaches to verification. Free includes Quick checks and Private on-device mode; Pro is described as adding Thorough verification and all modes. Reasoning and citations make a verdict easier to scrutinize, while the confidence score and bias analysis help signal uncertainty and framing rather than replacing judgment.

Privacy and security

Claims submitted for standard checks are sent to FactGuard’s backend, though its privacy policy says they 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 clearest choice for claims a reader wants to keep off external processing systems.

The policy cites TLS for data in transit, Firebase App Check, cryptographic nonces for Sign in with Apple and password hashing by its authentication provider. Email support typically responds within 1–2 business days.

For developers and teams

FactGuard describes an early-access MCP server for Claude, Cursor or another MCP host, plus a Fact-Check API with a free tier of 100 calls per day. Its newsroom page says API access and team pricing are under development, so teams needing established API or team arrangements should not assume those are ready. The 100-call API tier is distinct from the consumer Free plan’s three daily checks.

Pricing

FactGuard uses a freemium model. Free costs 0.00 USD per free, billed forever, and includes three fact-checks per day, Quick checks, Private on-device mode and Fact Feed access. It is suited to occasional individual use; the daily quota and Quick-only web mode are meaningful constraints for frequent or deeper checking. The web app also limits free history to the 30 most recent checks.

FactGuard Pro, Annual costs 36.99 USD per year, billed per year, equivalent to $3.08/mo. It includes unlimited fact-checks, Thorough verification and all modes, shareable verdict cards, full Fact Feed access and priority new features, with a 1-week free trial. Pro also includes unlimited history, bulk export and image checks. This is the more suitable plan for regular users who need those capabilities, though the plan is marked coming soon.

FactGuard Pro, Monthly costs 4.99 USD per month, billed per month, and includes the same stated Pro features and a 1-week free trial; it is also marked coming soon. Monthly billing suits readers who prefer not to commit annually, at a higher stated monthly rate than the annual equivalent. Both paid plans are presented as coming soon, so they are not a dependable immediate upgrade path.

Platforms

FactGuard is available on web and iOS, and offers API access. Its Private mode is described as on-device verification; its stated privacy distinction is that this optional mode is not transmitted for third-party processing.

Who it's for

FactGuard is a sensible fit for readers who want short claims checked with citations, reasoning and a confidence signal, especially if they value the option of on-device verification. Free is enough for light daily use. People who need longer submissions, frequent checks, image analysis, extensive history or bulk export have reason to consider Pro, but should account for its coming-soon status. It is less suitable as a final authority or as a ready-made team fact-checking system.

Pros and cons

• Pros: Verdicts include reasoning and citations, so readers can inspect supporting web evidence.
• Pros: Private on-device mode is included in Free and is not transmitted to FactGuard or third-party processing providers.
• Pros: Pro is described as removing check and history limits and adding image checks and bulk export.
• Cons: Free allows only three checks per day, uses Quick mode on web and retains only 30 recent checks.
• Cons: Web submissions are limited to 1,000 characters, restricting use with longer text.
• Cons: Paid plans are marked coming soon, and automated verdicts may be inaccurate, incomplete or out of date.

Alternatives

AI Fact-Checking Tools is a broader directory for readers comparing tools across the category.

Choose VerumVerify if Android support matters or a weekly allowance of three checks and a global news feed better fit your use; its free plan also limits Rumor Mailbox to verdict-only and excludes Document Scanner.

Avancer Document Fact-Checker is a better match for someone prioritizing image, audio and document scans, with one free scan and no credit card required.

Crowdee fits users focused on image verification: its free tier provides one image verification per IP every 24 hours, with uploads up to 10 MB and a verdict, confidence score and supporting indicators.

Factward may suit readers who need URL and PDF checks, up to five claims per check and shareable reports in its free plan, rather than FactGuard’s 1,000-character web limit.

FAXTR is worth considering for API use: its free plan provides 1,000 API calls per month, 10 requests per minute and community support.

Groundery is the more relevant alternative for live, recorded or transcript fact-checking and Chrome extension use; its free plan includes three hours of checking and ten instant text checks per month.

Trusul offers basic text and URL analysis with limited daily analyses and saved history on its free plan, for readers who want a web-only option.

Veritier is aimed at readers needing explicit API quotas: its free tier includes 25 verifications, 100 extractions and five authenticity scans per month, plus two API keys.

Verdict

Choose FactGuard for short, cited checks with a confidence score, framing analysis and a private on-device option. Its free tier is useful for light use, but the three-check daily allowance and Quick-only web mode constrain regular work, while Pro’s stronger tools are marked coming soon. If you need a dependable paid workflow now, deeper verification or an established team/API setup, look elsewhere; in any case, treat its verdict as a prompt to examine the cited evidence, not the last word.
