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.
