About
Checkwise verifies factual claims and returns a verdict backed by the sources it actually used, rather than an unexplained confidence score. A claim can be submitted as plain text, as the URL of an article, or checked against a live video while it plays. For each check, Checkwise searches for evidence, reads the pages it finds, and reports a verdict per source together with the passage that supports it. Every source carries a reliability grade from A to D, computed before the check from criteria such as editorial rigour, correction practices, transparency of ownership and funding, and reputation. The grading methodology is published, and each graded site has a public page explaining its grade, so an editorial team can trace why a verdict came out the way it did and contest a grade. Available as a web application, a browser extension for Chrome, Firefox, Edge and Brave, and a REST API for teams running checks inside their own editorial or moderation pipeline.

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.
