Questions
Free tools, answered.
Are these tools really free?
Yes. Every tool is free, with no sign-up and no watermark. We build them because they help businesses, and some of those businesses later try RapBooster.
Do you store what I type?
Almost every tool runs entirely in your browser, so nothing is uploaded. The idea generators send only your topic keywords to our server to create suggestions, and we don't store them.
What does “Sample answers” or “Preview” mean on a tool?
The idea generators use smart templates and curated libraries for now. A preview tool shows how a feature will work before its server side goes live.
Can I suggest a tool?
Please do. Message us on WhatsApp; the most-requested tools get built first.
