Use Case Recommendations
Best for: AgentReady
AgentReady is an interface layer that makes a documentation site queryable by AI agents. The problem it states is concrete: agents trying to use your docs parse raw HTML, miss a large share of the pages, and then hallucinate answers about your product. AgentReady crawls a site you nominate, indexes it, and gives it three things agents can actually consume — a hosted MCP endpoint they connect to immediately, a spec-compliant llms.txt at the site root that agents discover without any code change, and a capability manifest. Queries return cited answers: exact quotes with source URLs rather than a generated paragraph, so an agent's response is grounded in your actual content. Setup is claimed at under a minute with no code — sign in with Google, paste a URL, and the crawler indexes the pages (the demo shows 218 pages indexed and the MCP endpoint live). The second half of the product is the feedback loop: agent analytics show which agents are querying your docs and what they are asking, and query gap detection surfaces the questions your content does not answer. Paid tiers add an agent simulator that scores your site on five tasks, GitHub check runs on every refresh so a docs change that breaks agent answers fails CI, and Slack regression alerts. There is also a free grade report for measuring where a site stands before committing, and a public directory of indexed sites.
Ideal use cases:
- •Teams or individuals who need hosted mcp endpoint for any docs site in under a minute, no code
- •Teams or individuals who need spec-compliant llms.txt generated at the site root
- •Teams or individuals who need cited answers with exact quotes and source urls
- •Teams or individuals who need agent analytics showing which agents query you and what they ask
- •Anyone focused on mcp workflows
- •Anyone focused on llms-txt 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
