Choosing a tool
Frequently asked questions
Are these tools really free?
Yes. No signup, no email gate, no usage limit and no trial that expires. They run as JavaScript in your browser, so they cost us nothing to serve and nothing you type reaches a server.
Do you store what I paste in?
No. The content scorer and readability checker analyse text entirely client-side. There is no request to any server, no analytics event carrying your content, and nothing written to storage.
Where do the benchmark numbers come from?
Named published sources, linked on each page: the First Page Sage position-CTR meta-analysis, Ahrefs' measurement of the AI Overview click reduction across 300,000 keywords, and Pew Research Center click data. Tool prices come from vendor pricing pages. Full list on the statistics page.
Can I use these for client work?
Yes, freely. If you find them useful, a link back is appreciated and never required.
