How it works

Start testing your website copy in less than 5 minutes.

1. Provide a URL

Provide a URL of a page that contains the text element you want to test. Cline will fetch the text elements from the page.

2. Create experiment

Select the text element you want to test. You can select one text element per experiment. You can always create more experiments if you want to test multiple text elements on the same page.

3. Install tracking script

Install the Cline script on your website between the opening <head> and closing </head> tags. This will allow Cline to serve the different variants to your visitors. Alternatively, you can connect a Webflow site with just a few clicks.

4. Add variants

Utilize generative AI to quickly generate five variants at a time based on your original text. Variants can also be created manually or edited after generation.

5. Start experiment

Set a conversion goal before starting your experiment to track success directly from the experiment page. Once you've created more than one variant, Cline will begin serving them to your visitors, allowing you to monitor and analyze how each variant influences the achievement of your conversion goal.
