zRev AEO Lens by zRev AI

zRev AI's free AEO checker: how ChatGPT, Claude and Perplexity read the site you're on. llms.txt grade, schema, crawlers, cold read.

zRev AEO Lens is the free browser tool from zRev AI (zrev.ai), the AI-powered go-to-market consultancy for B2B software companies. Buyers increasingly ask ChatGPT, Claude and Perplexity before they ask Google. In one click, the Lens shows you how those systems read the website you are looking at. Click the zRev AI icon on any site and you get: AEO readiness score out of 100 • llms.txt: present or missing, graded on seven checks • Structured data: which schema types the homepage declares • AI crawlers: whether robots.txt lets GPTBot, ClaudeBot and PerplexityBot in • The cold read: what an AI thinks this company does, from the homepage text alone. If that is not what they would say about themselves, the homepage is not saying it. Then fix it. "Improve llms.txt" opens zRev AI's free generator with the domain prefilled: a specific fix for every miss and an improved draft that keeps everything already written. No account, no sign-up, no tracking. Run it on your own site first. Then on your competitors'. Then on your prospects', before the call. The same scoring code produced zRev AI's study "The State of AEO in B2B SaaS, 2026", which read 274 well-known B2B software sites: 61% publish an llms.txt, 4% block an AI crawler, and one in twelve could not be read at all. Read it at zrev.ai/insights. About zRev AI: zRev AI helps B2B software companies grow revenue faster by building AI into the sales and marketing systems they already use: lead scoring, routing, outreach and forecasting, inside their own HubSpot or Salesforce. The grader and the generator behind this extension are the same engine as zRev AI's public MCP server and its answer-engine optimization (AEO) audits.
