Avancer Document Fact-Checker extracts factual claims from PDF documents and checks them against live web sources. It returns a verified, unverified, or source-not-found result for each claim, with evidence and a confidence score. Checks cover factual errors, fabricated citations, and misinformation; the service also estimates the proportion of a document written by AI. The page estimates roughly 20 seconds of scanning per 1,000 words. Users can work through the web service or self-hosted options, while the API accepts a document URL or raw text and returns claim-level results with sources. Claim extraction and verification are listed for more than 70 languages. Files are processed for the scan and deleted afterward; the maker says documents are not shared or used to train models. The free plan includes one scan. Basic costs $12.99/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.
