free tools, ten of which never ask for an email
The freeTools list in lib/free-tools.ts. Three run entirely in your browser and send nothing anywhere.
Three questions decide whether an assistant recommends you. Can it read your site, does it already name you when a buyer asks, and whose pages is it building the answer from instead. The free tools answer all three, in that order.
Ten of the eleven need no email at all, and three of those never send anything off your machine because they are generators rather than checkers. The one that asks for an email is the citation scan, which spends real model money per run.
Where it lives: /tools, and each tool has its own page.
Three never send anything off your machine. One asks for an email, because each press spends real money on live model calls.
The readiness checker runs all eight site checks. The robots.txt check reads your file for GPTBot, ClaudeBot, PerplexityBot and Google-Extended, including blanket rules you never wrote. The sitemap validator and structured data validator cover the two files most often broken in ways nobody notices.
The ChatGPT, Perplexity and Grok visibility checkers put one buying question to each engine and show you whether your brand appears, whether your domain is cited, and who got recommended instead. The engines disagree often enough that checking one is not checking the others: across 36 questions in August 2026, ChatGPT and Grok cited only 8 domains in common.
The Citation Source Radar ranks the sites supplying your category's answers by share of citations, and tells you whether your domain shows up in that corpus anywhere.
Free, permanently. No plan required and none of them upsell mid-check.

The readiness checker is not: it runs all eight checks. The visibility checkers run one question instead of a scheduled library, and the source radar runs three instead of your whole library.
The checkers do not keep results. The citation scan records a telemetry row that a scan happened, because it costs money and we need to see abuse.
The visibility checker, because it takes ten seconds and the answer usually decides whether the rest of this is urgent.
Readiness checks
The floor: whether the engines can fetch, parse, and understand your site, with the fetched bytes attached to each verdict.
FreePublic citation scan
The front door: a real citation corpus for any domain, email-gated, cached for a day, no signup.
MonitoringAI visibility monitoring
Scheduled per-engine checks with a 0-100 score, tracked separately for being named and for being linked.
Start with the free visibility check to see whether the engines name you today, then run the scan that shows which pages they used instead.
