FastLLM: AI Search (AEO) Auditor & Markdown Clipper

Audit any website for ChatGPT, Perplexity & Claude AI visibility, generate llms.txt & JSON-LD, and clip clean LLM Markdown.

Inspect how ChatGPT, Perplexity, and Claude read your website. Audit AI crawler access, generate llms.txt files, and convert web pages into clean Markdown for LLM prompts. As search engines shift from classic keyword lists to AI answer engines (ChatGPT Search, Perplexity, Google Gemini, and Claude), websites need to ensure AI crawlers can actually access and understand their content. FastLLM gives you a practical two-in-one tool directly in your browser: an AI Search (AEO) Auditor and a clean Web-to-Markdown Clipper. What FastLLM does: 1. AI Search Visibility (AEO) Audit: - Checks your website's robots.txt to confirm whether AI crawlers (GPTBot, PerplexityBot, ClaudeBot, Google-Extended, and Applebot) are allowed or accidentally blocked. - Analyzes structured data (Schema.org JSON-LD) and meta tags to verify how AI models parse your company, products, and articles. - Calculates an instant AEO readiness score (0–100) with practical suggestions to improve your citation chances in AI answers. - Generates a ready-to-paste /llms.txt manifest file for your domain. 2. Web-to-Markdown Clipper: - Converts any active article, blog post, or documentation page into clean, readable Markdown with one click. - Automatically strips away ads, cookie banners, navigation menus, and sidebar clutter. - Displays live word and token count estimates so you know exactly how much context you are feeding into Claude, ChatGPT, or your local LLM. - One-click copy to clipboard or download as a .md file. How to use: 1. Click the FastLLM icon in your toolbar on any website. 2. In the "AEO Audit" tab, click "Audit Site" to view crawler permissions and structured data readiness. 3. In the "Markdown Clipper" tab, click "Extract to Markdown" to grab clean, token-efficient text for your AI workflow. Who is this for? - Website owners and founders who want their brand cited by AI search engines. - SEO and content teams optimizing for Answer Engine Optimization (AEO / GEO). - Developers and researchers feeding web articles and documentation into LLM prompts without token bloat. Free to use with no account required. Runs entirely on-demand in your active browser tab.
