Which AI-search tool should I start with?
Start with the question you actually have. Most of these tools run in your browser, show their formula or rule set on the page, and grade their claims against published evidence rather than vendor marketing.
- "How much traffic is AI search costing me?" Measure exposure with the AI Overview checker, then put a range on it with the AI traffic loss calculator.
- "Can AI crawlers reach my site?" Paste your file into the robots.txt tester for AI crawlers, and check real visits with the AI crawler log analyzer.
- "Is this GEO advice worth following?" Look the tactic up in the GEO tactic evidence lookup before you spend time on it.
- "Is my page set up to be cited?" Run the citation readiness checker, and see whether your topic has a Wikipedia article with the Wikipedia gap finder.
- Everyday SEO checks: the keyword density checker, SERP snippet preview and schema generator.
What these tools can't tell you
No tool here gives you a single "AI visibility score", on purpose: the evidence doesn't support combining different signals into one number. Calculators produce planning ranges from published, vendor-reported figures, and checkers test for what's on your page, not whether an AI engine will cite it. Where a figure is shaky, the tool page says so. Video and social downloaders live on the downloaders page.
Free result first. Always.
Every tool gives you the full answer on the page. Nothing is gated, there is no signup, and most tools run entirely in your browser.

Each tool points back at its evidence
None of these coefficients came from nowhere. Every number a tool applies is published on this site, with the population it actually describes still attached.
- AI Overview Exposure Checker applies the published trigger rates by query type, and the CTR figures from the CTR statistics page.
- llms.txt Generator exists alongside a 90-day first-party log test that found nothing meaningful reading the file — the honest case for shipping one anyway is there.
- Schema Generator produces the types in the pre-registered schema study, which asks whether markup causes citations rather than assuming it.
- AI Traffic-Loss Calculator runs on the CTR-loss coefficients traced in the provenance audit and the behaviour data in the zero-click figures.
Where a tool's mechanism is unproven, the tool says so. Every tactic on this site carries an evidence grade, and the tools are held to the same standard as the writing.
