Free tools for AI visibility
AnswerFix builds three free tools that each fix one specific, mechanical reason ChatGPT, Perplexity, and Gemini fail to find or recommend a local business: missing structured data, no llms.txt summary, and robots.txt rules that accidentally block AI crawlers.
Every tool here runs without a signup, a credit card, or a sales call, and every one follows the same rule: nothing is invented on your behalf. The schema and llms.txt generators only output what you type in, clearly showing what is still missing rather than filling gaps with a placeholder that looks real. The crawler checker only reports what your own robots.txt file actually says, read live from your server at the moment you run the check.
These tools address the mechanical layer of AI visibility: can a crawler reach your site, and can it extract clean facts once it is there. They do not test whether AI engines actually recommend you over competitors for the questions your customers ask, which depends on far more than schema and robots rules. For that, run the free AI visibility score below, which sends real prompts to ChatGPT, Perplexity, and Gemini and reports whether your business gets named.
Local Business Schema Generator
Build a paste-ready LocalBusiness JSON-LD block from your name, address, phone, category, hours, and social profiles, with the correct Schema.org subtype for your business.
Open toolllms.txt Generator
Turn your business summary, services, and key pages into a valid llms.txt file in the llmstxt.org format, ready to upload to your site root.
Open toolAI Crawler Checker
Check your live robots.txt against the eleven crawlers that feed ChatGPT, Claude, Perplexity, Gemini, Bing, and Apple Intelligence, with a fix for anything blocked.
Open toolFree tools questions
- Are these tools really free, with no signup?
- Yes. All three tools run without an account, a credit card, or an email address. The schema generator and llms.txt generator run entirely in your browser, and the crawler checker makes one server-side request to read a public robots.txt file, nothing more.
- Do these tools store the business information I type in?
- No. The schema and llms.txt generators keep everything in your browser's memory only; nothing is sent to AnswerFix's servers or saved anywhere. The crawler checker only sends the website address you enter, purely to fetch that site's public robots.txt file.
- How is this different from the free AI visibility score?
- These tools each fix one specific, mechanical piece of AI readiness that you control directly. The free score instead tests whether ChatGPT, Perplexity, and Gemini actually recommend your business today, across real prompts, and ranks every problem behind that result, not just the three covered here.
- Which tool should I start with?
- Start with the AI crawler checker, since a blocked bot makes every other fix pointless for that engine. Then add LocalBusiness schema for machine-readable facts, and finish with llms.txt as a low-cost extra once the first two are live on your site.
