Eustace vs FAXTR

Eustace is a web-based fact-checking workspace for writers and researchers working with AI-assisted drafts. Users can paste text or import a URL, PDF, or Word file; scanned PDFs are processed with OCR. The service extracts candidate factual claims and displays their original quotes so users can select which to verify. Approved claims are checked against fresh web sources rather than the submitted document. Its ledger uses ten verdicts and three confidence levels, and the product says it signals uncertainty when evidence is thin or mixed. Users can inspect sources, attach private evidence, override a verdict with the change recorded, and export a Markdown report with claims, verdicts, confidence, and citations. Eustace says it does not sell user data or use documents to train AI models. The Free plan provides 25 lifetime verifications; Pro costs $19/month for 500 each month, with optional $0.05-per-claim overage turned off by default. Automated verdicts, confidence labels, and summaries can be wrong, incomplete, or out of date, so they are intended to support rather than replace editorial judgment.

FAXTR is a fact-checking platform for reviewing claims, headlines, articles, article URLs, and LLM-generated text. It aggregates verdicts from more than 100 fact-checking organizations across more than 50 countries, rather than making its own final judgment on whether a claim is true or false. Visitors can make three checks without signing up; signing up provides more checks and history. FAXTR says it gathers data from the Google Fact Check Tools API and Google News RSS three times daily. For integrations, it offers a REST API with JSON responses at https://api.faxtr.com/v1. Verification endpoints are in private beta and require access; the API also includes a /v1/guard endpoint for scanning LLM responses for misinformation. FAXTR Verified records source and receipt details, source-text and debunk matches, and a published SHA-256 fingerprint of an article body. Publishers add it with one server-rendered link per article, without JavaScript or a runtime dependency on FAXTR. The Free plan is free, billed monthly; Starter is $49 a month.
