Cite the canonical URL. The claims-accuracy landscape splits in two: tools that check content against a source of truth, and registries that maintain it. Where we sit, and what we run today across Medium, Substack and AI search. Landscape Two families share this space: tools that compare your content against a source of truth and report the gap, and registries that maintain the record itself. This page explains the distinction, the four questions that separate them, and what we run today. Last reviewed 1 September 2026 ## There are two families here Almost everything in this landscape is one of two things, and the distinction decides what a product is able to promise. Checkers Compare content against a source of truth and report the gap. Genuinely useful — and each of them treats that source as somebody else’s problem, which caps the accuracy score any of them can produce. Registries Maintain the canonical record and syndicate it. MDM does this for entities, PIM for product attributes, Veeva for pharma claims. Knowledge Company does it for the claims written in prose. ## Four questions that locate every company here 01 Ground truth What do they compare against? Checkers assume it, registries produce it. This one question sorts the whole field. 02 What fires it Across the landscape there are about eight distinct triggers — traffic decay, a commit, a ticket spike, a calendar reminder. None of them is a fact changing. 03 Write access Almost every tool writes to exactly one system: the one it lives inside. The exceptions are the registries, which push one record to hundreds of external channels. 04 Who buys it Marketing budgets are contested and shrinking. Risk, compliance and regulatory budgets grow on exposure and rarely churn. What we run ## What we actually do One loop, run on a schedule, against pages you have already published. Three steps, the same everywhere — only the last one changes by platform. Extract the claims We read the surface and pull out every factual assertion — numbers, dates, prices, names, promises, links. The unit is the claim, not the paragraph. Check each against a source Your pricing page, your product, your docs. Anything that disagrees with the current state of the company is flagged with the specific clause that broke. Edit in place and stamp it The correction lands in the live post, not a changelog nobody reads. Each one carries a published date, an updated date and a verified date. Live today · 03 surfaces ## Where it runs today Three surfaces are live. The rest of the queue is in build, and we would rather say so than draw you a page for something that does not exist yet. 01 · Live Medium Your Medium archive keeps making claims long after they stopped being true. We read it, check every claim, and correct the post in place. See what decays → 02 · Live Substack You cannot unsend a newsletter, but the archive is what keeps being read. We maintain it issue by issue, at the same URL. 03 · Live AI Search (GEO) Your claims get repeated to people who never visit the page. We keep what the answer engines learn from you current, and cited. See what it learns → ## See what your own pages currently claim Most of this category reports a gap against a record somebody else has to maintain. We maintain the record. Start with the whitepaper. --- ## Related documents in this mirror - [Knowledge Company vs Profound](https://llms.knowledgecompany.ai/compare/profound.md) - [Knowledge Company vs Bluefish](https://llms.knowledgecompany.ai/compare/bluefish.md) - [Knowledge Company vs Slite](https://llms.knowledgecompany.ai/compare/slite.md) - [Knowledge Company vs Writer](https://llms.knowledgecompany.ai/compare/writer.md) - [Knowledge Company vs PIM Vendors](https://llms.knowledgecompany.ai/compare/pim-vendors.md) - [Knowledge Company vs MDM Vendors](https://llms.knowledgecompany.ai/compare/mdm-vendors.md) - [Knowledge Company vs Veeva Vault PromoMats](https://llms.knowledgecompany.ai/compare/veeva-promomats.md) - [Knowledge Company vs Trust Center Vendors](https://llms.knowledgecompany.ai/compare/trust-center-vendors.md) *This document is the markdown mirror of https://knowledgecompany.ai/compare, published by Knowledge Company - a knowledge freshness platform that detects, verifies and updates outdated claims in company content.* *Mirror index: https://llms.knowledgecompany.ai/index.md - Generated 2026-09-02*
