Avancer Document Fact-Checker

Summary

Avancer Document Fact-Checker reviews PDF documents by pulling out factual claims and checking them against current web sources. It gives each claim a verified, unverified, or source-not-found result, with supporting evidence and a confidence score. Checks cover factual errors, fabricated citations, and misinformation; the service also estimates the share of a document written by AI. The document page estimates a scan takes about 20 seconds per 1,000 words. You can submit documents through the web service, use self-hosted options, or send a document URL or raw text through the API. Claim extraction and verification are listed for more than 70 languages. Files are deleted after analysis and are not used to train models or shared. A free plan includes one scan. Basic costs $12.99/month and includes 1,299 credits, text scanning, API and webhook access, email support, and PDF report export. A seven-day trial is also listed.
