In their own words
Avancer Document Fact-Checker
Avancer Document Fact-Checker extracts factual claims from PDF documents and checks them against live web sources. Each claim receives a verified, unverified, or source-not-found verdict, along with evidence and a confidence score. The service checks for factual errors, fabricated citations, and misinformation, and estimates how much of a document was written by AI. Its page estimates about 20 seconds of scanning per 1,000 words. Documents can be checked through the web service, self-hosted options, or an API that accepts a document URL or raw text and returns claim-level results with evidence and sources. Claim extraction and verification are listed for more than 70 languages. Files are processed for the scan and deleted afterward; documents are not used to train models or shared. A free plan includes one scan. Basic costs $12.99 per month and includes 1,299 monthly credits, text scanning, API and webhook access, email support, and PDF report export. A seven-day trial is listed. The maker also lists SOC 2 Type II and GDPR compliance, with ISO 27001 in progress.
FactGuard
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 FactGuard cautions that automated verdicts can be inaccurate, incomplete, or out of date and advises checking cited sources.
