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

ProofWrite is an AI research and writing platform built for SEO agencies, link builders, guest post providers, and content marketing teams. It helps create researched, cited, fact-checked SEO articles and publisher-ready guest posts built around a keyword, client URL, or anchor text. Unlike generic AI writers, ProofWrite follows a research-first workflow: it gathers source material, plans a relevant article angle, writes from evidence, checks claims, adds citations, and reviews link placement so drafts read like genuine editorial content rather than AI filler. ProofWrite is designed for guest posting, niche edits, digital PR, SEO agency deliverables, client content workflows, and multi-site publishing.
