Use Case Recommendations
Best for: AIRIX
AIRIX is an AI-visibility tracker built around a weekly cadence rather than a live dashboard. It scans sixteen AI platforms — ChatGPT, Gemini, Claude, Perplexity and others — for questions in your category, then reports on three things every Monday: a single 0-100 score for whether AI buyers can find you, a log of which competitors were cited instead of you and on which engines, and a set of ready-to-ship assets closing the gaps the scan found. Those assets are the part that distinguishes it from a pure monitoring tool: structured data and answer-shaped copy generated weekly and tailored to the business, meant to be copied and deployed without an agency in the loop. The site is unusually careful about teaching the underlying concepts, with plain-English definitions of AI visibility, llms.txt, generative engine optimization and answer engine optimization sitting on the homepage, and it labels its own dashboard screenshots as fabricated illustrative samples rather than passing them off as customer data. There is a free visibility checker and a free ads tracker that run without an account, plus a listing in the company's own AI Discovery Index, an on-page audit, a public profile and an MCP connector for pulling the data into an assistant. It is priced and positioned for small local and service businesses.
Ideal use cases:
- •Teams or individuals who need weekly scan across sixteen ai platforms with a single 0-100 visibility score
- •Teams or individuals who need per-platform breakdown of where you are and are not cited
- •Teams or individuals who need competitor tracking showing who ai recommends instead
- •Teams or individuals who need generated structured data and answer-shaped copy to deploy each week
- •Anyone focused on geo workflows
- •Anyone focused on aeo workflows
Best for: llms-txt.io
llms-txt.io generates, validates and — the part that matters — keeps current the llms.txt and llms-full.txt files that AI coding assistants read to understand a site or a documentation set. The generator turns any site into a spec-compliant llms.txt with AI-written summaries and a description per link, and it is free with no cap on web generation; the validator lints any existing file by URL or pasted content and returns a structured agent-readiness score with actionable findings rather than a pass/fail. Those two are the free half and they are genuinely useful on their own. The paid half addresses the actual failure mode of this file format, which is not creating it but the fact that it silently rots the moment the docs change. Managed sites are registered once and regenerated automatically on a weekly or daily schedule, served from a stable URL and pushed to a webhook on every change, so downstream consumers learn the file moved without polling. An API with keys and monthly quotas exposes generation and validation to CI, which is where a team that cares about this should be running it — regenerate on docs deploy, fail the build if the validator score drops. The site claims over 50,000 files generated. Two limits to size: llms-full.txt page depth is tiered, running 20 pages on free up to 100 on Pro, and managed-site counts are the real meter at 1 site on Starter and 10 on Pro.
Ideal use cases:
- •Teams or individuals who need free spec-compliant llms.txt and llms-full.txt generator with ai-written per-link descriptions
- •Teams or individuals who need free validator scoring any llms.txt by url or pasted content for agent readiness
- •Teams or individuals who need managed sites regenerated weekly or daily and served from a stable url
- •Teams or individuals who need change webhook fired on every regeneration so consumers do not have to poll
- •Anyone focused on llms-txt workflows
- •Anyone focused on aeo workflows
