FastLLM: AI Search (AEO) Auditor & Markdown Clipper

Check AI-crawler access, llms.txt and JSON-LD on any site, generate those files, and clip pages to clean Markdown.

FastLLM is a technical-readiness checker for AI search and a web-to-Markdown clipper, built for SEO professionals, e-commerce founders and AI engineers. What it checks (readiness signals only): It does not measure whether any AI assistant or answer engine actually cites your site, and it cannot promise more AI traffic. It checks the technical basics those systems depend on. 1. Readiness score (0-100) and grade A heuristic score built from the checks below. Use it as a checklist, not a ranking. 2. AI crawler access Reads your robots.txt and shows whether the crawlers used by the major AI search providers are allowed or blocked. 3. /llms.txt and structured data Detects whether /llms.txt exists and which Schema.org JSON-LD types are present (Organization, Product, Offer, AggregateRating). Pro generates a ready-to-paste manifest and JSON-LD snippets for the audited site. There is no independent evidence yet that this file changes how AI engines cite a site. 4. Web-to-Markdown clipper with token counter Strips navigation, ads and popups from an article or documentation page and converts it to clean Markdown with word and estimated token counts, for use in LLM prompts and RAG pipelines. Free plan: 3 audits and 10 clips per day. Pro ($19 one-time): full generated /llms.txt and JSON-LD output, unlimited audits and clips. How to Use: 1. Click the FastLLM toolbar icon on any website. 2. In the "AI Search Audit" tab, click "Audit Site". 3. In the "Markdown Clipper" tab, click "Extract Active Tab to Markdown" to copy or download the result. Privacy: FastLLM runs only when you click the extension icon. It does not track your browsing history and does not sell or share user data. When you audit a domain, the domain is sent to neoninnovationlab.com, together with a license token if you activated Pro. Page clipping happens in your browser.
