A/B Test Generator
Hand your CRO agent any copy or URL. CROW tells you first whether it is even worth testing — then writes up to 5 versions that persuade in genuinely different ways, each with what to measure and how long it needs to run.
How the A/B test idea generator works
Before writing any variants, it decides whether a test is worth running at all. On a page without much traffic, a test can take months to give a reliable answer. When that's the case it says so, and what to do instead.
- Paste your copy or a page URL. Add anything you know about the audience if you like.
- It reads what's there now and gives a verdict on whether to test.
- If a test is worth running, you get up to five variants, each with the idea behind it, who it's for, a hypothesis and the number to watch, plus the one it recommends.
Questions
- Why did I get fewer than five variants?
- It only writes variants that test a genuinely different idea. Two headlines that make the same promise in different words are one test, not two.
- Why would it tell me not to test?
- A test needs enough visitors to tell a real difference from chance. If your page can't get there in a reasonable time, the honest answer is to make the change and measure it, and that's what it will tell you.
- Is it free?
- Yes, and you don't need an account. The free allowance is 3 runs a day, shared across CROW's AI tools, and a run that fails doesn't count. Pro is $19 a month for 300 runs a month.
