About
Lenz is an audit-grade fact-checking API for AI-drafted text, built for teams that need to check factual claims before customers or clients see them. It reads a draft, memo, model answer, or page of copy, extracts the factual statements that can be checked against independent public sources, and returns a result for each. Its workflow follows four API primitives: extract verifiable claims, assess them in bulk with a fast multi-model verdict, escalate uncertain statements to a full verification, and ask follow-up questions grounded in the verification. Full verification runs through a structured five-stage pipeline of framing, research, debate, panel review, and conclusion. Lenz searches public sources, scores evidence for authority, relevance, and recency, has models from multiple vendors argue both sides of a claim, and returns a verdict, confidence score, cited sources, and reasoning trace that users can audit.

About
World ID is a privacy-preserving protocol that lets people prove facts about themselves online without sharing unrelated personal information. The World ID app lets users claim, manage, and present cryptographic proofs, including Proof of Human, Proof of Presence, and Proof of Attributes such as age or nationality. Proof of Human is obtained through Orb verification, while other proofs can be claimed through supported verification methods. People use World ID with participating apps and services for human verification and access checks. Developers can integrate World ID into web, mobile, and decentralized applications to help limit bots and duplicate accounts and verify human participation. The protocol is open source, and available proofs, integrations, and verification methods vary by location and implementation.
