Free tools
Free tools for docs writers and SaaS teams.
A small toolkit covering AI discoverability, technical authoring, and on-page SEO. No signup, no email gate, no "upload your data and get rate-limited". Each tool runs in your browser or hits an API — that's it.
AI Discoverability
llms.txt Generator→
Generate a curated llms.txt and llms-full.txt for any website. Helps Claude, ChatGPT, and Perplexity find and quote your docs.
Crawls your site, picks the doc-worthy pages, and writes the file to spec.
AEO / GEO Audit for Docs→
Free Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) audit. Score how well ChatGPT, Claude, and Perplexity can cite your documentation.
Checks llms.txt, sitemap, schema, headings, robots.txt, and content quality. Powered by Gemini 2.5.
AI Robots.txt Generator→
Configure exactly which AI crawlers can read your site. GPTBot, ClaudeBot, Perplexity, Google-Extended — toggled per bot.
Generates a ready-to-paste robots.txt that handles all the modern AI crawlers, not just Googlebot.
Authoring
AI README Generator→
Drop in any public GitHub URL — Gemini 2.5 pulls the repo's real metadata and writes a polished README.md with the right sections.
AI-generated install, usage, examples, and contributing sections — populated from your repo's actual language, license, and topics.
Docs Readability Score→
Paste markdown or a docs URL. Get a readability score plus Flesch-Kincaid Reading Ease + Grade Level, heading depth, and an AI rewrite of the worst section.
Hemingway-style, but tuned for technical writing — flags jargon density, run-on sentences, and acronym overload.
