Questions
Free tools, answered.
Are the tools free?
Yes. Every tool is free to use, with no sign-up and no email.
Do the tools store my data?
No. The calculators and generators run in your browser. The checkers fetch only the public page or file you enter, and keep the result for up to an hour so the same page isn't fetched again and again.
Which tool should I start with?
The AEO Checker shows whether a page is ready to be quoted in AI answers, and the Robots.txt Tester shows whether search and AI crawlers can reach your site. If you run ads, start with the ROAS Calculator or the Cost Per Lead Calculator.
