Meedan Check vs Veritier

Meedan Check is free, open-source software for organizations running fact-checking and media annotation work. It is aimed at independent media, civil society, and human rights groups handling information needs during elections, protests, and public-health emergencies. Partners can operate tiplines that receive community submissions through WhatsApp, Messenger, Telegram, LINE, and Viber, then collaborate with trusted groups. The workspace supports text, URLs, images, video, and audio, with assisted fact-checking, claim detection, citation links, a browser extension, and API access. Multilingual AI tools help identify trends and organize media. Listed connections include WhatsApp Business API, Zendesk Sunshine Conversations, Slack, and Zapier. In 2025, Check supported 34 languages and dialects, served 143,631 unique users, and powered 58 tiplines. Data is hosted in Ireland, encrypted in transit and at rest, and access is limited. Organizations control their data, which is shared only with explicit consent. Check is available through web, API, and extension interfaces.

Veritier extracts checkable claims from text, URLs, PDFs, and images, then compares them with live web evidence or private references. Results provide a verdict, confidence score, plain-language explanation, and source links. The service is available through a REST API, MCP server over Streamable HTTP, local stdio proxy, and browser interface, with parsing and OCR built into its pipeline. The attest_action endpoint checks named records such as npm, PyPI, CourtListener, SEC EDGAR, and the U.S. Code, blocking actions when records cannot be confirmed. Attestations create Ed25519-signed Claim Credentials that can be checked through JWKS and revoked; credentials remain for 400 days. Requests can use webhooks and signed retries. Free-tier text may be retained and used to improve models, while paid-tier payloads are processed ephemerally and excluded from foundation-model training. The free tier allows 25 verifications monthly; paid plans start at $19.99 a month. Verdicts and confidence scores are probabilistic.
