What it is

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 nothing, 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 FactGuard cautions that automated verdicts can be inaccurate, incomplete, or out of date and advises checking cited sources.

FactGuard in depth

Read the full write-up

FactGuard is an automatic fact-checking service for claims, headlines, statements, URLs and images. It best suits readers who want a cited first assessment of a short claim, with a private on-device option when privacy matters. The free tier is useful for occasional checks, but its caps and the Pro plans’ coming-soon status make it a poor fit for dependable, high-volume research today.

Overview

Each check returns a verdict, reasoning and links to web sources, alongside a confidence score from 0 to 100 and analysis of framing and potential bias. That is a helpful package for deciding what to investigate further: the citations expose the basis for a result, while the score and bias analysis add context. Neither makes the verdict conclusive. FactGuard warns that automated checks can be inaccurate, incomplete or out of date, so readers should assess the cited evidence themselves.

The web app accepts claims up to 1,000 characters. That favors short claims over long articles or documents, and its free tier is restricted to Quick mode. Images are supported, but image checks are a Pro feature.

Key features

Modes, history and image checks

FactGuard describes Quick, Thorough and Private verification. The free plan includes Quick checks and a private on-device mode; Pro is described as adding Thorough verification and all modes. Free web users can see only their 30 most recent checks, while Pro includes unlimited history and bulk export. Those Pro features would better suit regular research, but they depend on a paid plan that is marked as coming soon.

Pro image checks include provenance, metadata and first-seen checks that stay on the device. That local processing is a meaningful privacy distinction for image investigation, though it is not part of the free tier.

Privacy, security and integrations

Claims submitted for checking are sent to FactGuard’s backend, but the privacy policy says they are not stored per user on its servers. Optional on-device verification is not sent to FactGuard or third-party processing providers. The policy also names TLS in transit, Firebase App Check, cryptographic nonces for Sign in with Apple and password hashing by its authentication provider as security measures.

An early-access MCP server is intended for Claude, Cursor and other MCP hosts. FactGuard also describes a Fact-Check API with 100 free calls per day, although API access and team pricing are under development. These offerings are not yet a basis for teams to plan a production workflow. Email support typically responds within 1–2 business days.

Pricing

FactGuard uses a freemium model. The Free plan costs nothing, billed forever, and provides three fact-checks per day, Quick checks, private on-device mode and Fact Feed access. That is enough for occasional personal checks, but the daily allowance, Quick-only web mode and 30-check web history constrain sustained research.

FactGuard Pro, Monthly is $4.99 a month, billed per month; FactGuard Pro, Annual is $36.99 a year, billed per year, equivalent to $3.08/mo. Both are described as including 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. Both are coming soon, so neither is a currently usable upgrade. The annual plan has the lower stated monthly equivalent, but its yearly billing is less flexible than the monthly option. No seat allowance is stated, so the listed per-user rate should not be treated as a team price.

Platforms

FactGuard is offered on web and iOS, with API access also part of its platform offering. The web app is the clearest fit for occasional browser-based checks; API and team availability remain under development. The MCP server is described as early access.

Who it's for

FactGuard is a sensible choice for individuals who want a quick, cited check of a short claim and are willing to verify the evidence rather than accept an automated verdict outright. Its free daily allowance is also useful for trying the service without a subscription. Readers checking long passages, needing frequent Thorough checks, or relying on unlimited history should look elsewhere until Pro is available.

Pros and cons

Pros: Verdicts include reasoning, linked web sources, a confidence score and framing analysis, giving readers several angles for evaluating a claim.

Pros: Optional on-device verification is not transmitted to FactGuard or third-party providers, which gives privacy-conscious users a distinct checking option.

Cons: The web app’s 1,000-character limit and free tier’s three checks per day and Quick-only mode limit what occasional users can do.

Cons: Pro image checks, unlimited history and bulk export are tied to plans marked as coming soon, leaving frequent users without those upgrades for now.

Cons: FactGuard itself cautions that results may be inaccurate, incomplete or out of date, so it cannot replace review of the cited sources.

Alternatives

AI Fact-Checking Tools is a useful place to compare more options. Choose VerumVerify if Android support matters; its free plan allows three checks per week and includes a basic credibility score and global news feed, a smaller allowance than FactGuard’s daily quota. Consider Avancer Document Fact-Checker if you need image, audio and document checks through web, API or self-hosted platforms; its free plan is one scan, while FactGuard’s free web app is capped at 1,000 characters.

Omniscient AI may suit API users who prefer pay-per-request pricing: its metered plan has a $0 /mo base and charges $0.005 per fact-check request, rather than FactGuard’s daily free allowance. For more generous daily use and URL or PDF checks, Factward offers two verifications per day, 10,000 characters and up to five claims per check on its free plan. Trusul, Crowdee, FAXTR and Eustace are also alternatives.

Verdict

Choose FactGuard for occasional, short claim checks when cited reasoning and an optional private on-device mode matter more than a high free quota. Its free tier makes that use case accessible, but its character and history limits are real constraints, and the plans that promise unlimited checks and deeper verification are not yet available. Readers who need a dependable daily research workflow should choose an alternative rather than wait on Pro.

Verdict

FactGuard provides sourced claim checks, but its free web tier has a daily allowance and character limit. Treat verdicts as a starting point and review their cited sources, particularly because the listed Pro plans are not yet available.
