6 free SEO and AI-search tools, all running in the browser: Google SERP Simulator, Keyword Density Checker, ARD Checker, OKF Generator, AI Crawler Access Checker, Crawled - Currently Not Indexed Filter.

## Google SERP Simulator

Preview your title tag and meta description exactly as Google renders them, with pixel-accurate truncation. Stop getting cut off in the results.

## Keyword Density Checker

See how often your primary keywords appear and which phrases dominate your copy. Word-accurate density analysis for any article.

[Keyword Density Checker](/tools/keyword-density-checker/)

## ARD Checker

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.

[ARD Checker](/tools/ard-checker/)

## OKF 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.

## AI 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.

## Crawled - Currently Not Indexed Filter

Upload your Search Console "Crawled - currently not indexed" export and strip the noise. Feeds, pagination, media, archives and parameter URLs come out; what's left is the list actually worth your attention. Runs in your browser.
