Avancer Document Fact-Checker vs Factward

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.

Factward checks text, URLs, and PDFs by identifying factual claims and comparing them with web sources. Its AI model filters out opinions, predictions, and subjective statements, then retrieves up to five independent sources for each claim. Reports classify claims as Supported, Conflicting Sources, Refuted, or Insufficient Evidence, and include confidence, reasoning, linked sources, and a Trust Score. The service tracks when claims may have become stale and prompts users to check them again. A bookmarklet can send article text for review, and the Pro API can be used in a CMS or publishing pipeline. A beta Chrome extension highlights claims alongside verdicts and evidence, including when checking selected text from its context menu. Factward says submissions are used to produce results and are not sold or shared with third parties, though jobs and reports are stored in its database. Niche, paywalled, or very recent claims may lack evidence, and nuanced claims can be misinterpreted. The free plan allows two verifications per day; Pro costs $9 a month.
