Free SEO tools I actually use
Small, fast utilities I built for my own work and left running for anyone. No signup, no upsell: preview your SERP snippet, check keyword density, audit your agentic (AI) discovery setup, or generate an Open Knowledge Format bundle.

Audit any domain's Agentic Resource Discovery setup: validate its ai-catalog.json, confirm the four discovery signals, and test whether AI crawlers can actually reach it. Pass/fail with a grade.
open toolOKF Generator
Turn any domain into an Open Knowledge Format bundle: structured, cross-linked markdown that AI systems and search engines can actually parse. Enter a URL, get the files.
open toolAI Crawler Access Checker
See whether AI crawlers can actually read your site. Tests GPTBot, ChatGPT-User, ClaudeBot and PerplexityBot reachability, your robots.txt verdicts, response speed (the 499 risk), and firewall blocks, with a fix for anything blocked.
open tool// for ai agents
Building with AI agents?
The tools above are for people. I also expose this site's capabilities directly to AI agents over the Model Context Protocol — discoverable via Agentic Resource Discovery, the same standard the ARD Checker audits. If you are wiring up an agent, connect to the live MCP server and call them programmatically.
