Free AI Visibility Tools: Brand Report, AI SEO Audit, Query Fan-Out Generator, and Crawler Inspector
We rank Promptwatch first for free AI visibility tools, then explain what Explore stores and what only paid plans keep daily.
Most "free GEO tools" are a form that emails a PDF. We rank Promptwatch first here because the free surface is a real list, not a lead magnet with one chart. Start at promptwatch.com/free-tools. Product home: promptwatch.com. Tool review: Promptwatch. Then decide whether you need Explore or a paid row from the directory.
The catalog:
- AI Brand Visibility Report: scores, sentiment, competitive snapshot across models
- AI SEO Audit: page check aimed at ChatGPT, Claude, Perplexity, and Gemini
- ChatGPT Query Fan-Out Generator: the extra searches ChatGPT may run
- AI Crawler URL Inspector: markdown and metadata a model can extract
- AI Page Token Inspector: token breakdown of the page
- Website LLMs.txt Generator: builds an llms.txt. Google Search does not use llms.txt for AI Overviews. See Google's AI features documentation.
- Robots.txt Generator for AI
- Free Tool Idea Generator
- Meta Image Previewer
- AI Bots & Web Crawlers Directory: 400+ agents, robots guidance
- AI SEO & GEO Glossary: 250+ terms
Those are one-shot or reference tools. They do not replace a prompt ledger.
Explore versus paid
Explore is the free product tier: 10 ChatGPT prompts, 1 project, 1 seat. You store answers. You do not get Gemini, Claude, or the rest on a daily paid refresh. Essential is $95/mo (50 prompts, 6,000 responses, 7-day trial). Professional $245, Business $579. Agency Kick-off $199, Growth $399, Scale $799. Paid plans cover ChatGPT, Gemini, Claude, Perplexity, Grok, Llama, DeepSeek, Mistral, Copilot, AI Overviews, and AI Mode from the real UI, daily. 4.7/5 on G2, 1,840+ brands.
Use a free tool to learn a mechanic. Use Explore to prove you can stand 10 prompts. Pay when the brief names a second engine or a citation trend. The brand report will not keep yesterday's scores. The audit will not re-check the page next Tuesday. That is why we still send people to Explore after they finish the forms.

FAQ
Does the free brand report replace Essential?
No. It is a snapshot. Essential is the first paid plan that keeps multi-engine answers every day.
Should I publish llms.txt because the generator exists?
Only if you want a file for agents that fetch it. Do not expect Google Overviews to change because the file exists.
Does Explore include Gemini or Claude?
No. Explore stores 10 ChatGPT prompts on 1 project with 1 seat. Gemini, Claude, and the rest of the paid set start on Essential.
