03 / Questions
Questions, answered.
Are Whizo AI's free tools really free?
Yes. Every tool on this page is free to use with no signup required, up to 3 AI generations per tool every 24 hours. The engagement calculator has no limit at all. Signing in with a free Whizo AI account removes the limit on these tools. The Chrome extension is the one exception: it needs a Whizo AI account.
Do I need an account to use these tools?
No. All 8 tools work anonymously in your browser. An account is only needed if you want unlimited generations instead of the free 3-per-day cap, or want the content calendar and the rest of the platform.
What's the difference between these free tools and the full Whizo AI platform?
These tools are single-purpose utilities for quick, one-off tasks. The full Whizo AI platform adds a content calendar, multi-workspace client management, scheduled publishing, analytics, a lead finder, and unlimited use of these free tools.
Want it unlimited?
