To incentivize users to complete the branding quizzes, I designed a simple AI-powered writing assistant. The feature unlocks only after all three quizzes are completed, and lets users apply their previously defined tone of voice.

Free trial implementation
Free trial implementation
The free trial is being introduced to replace the freemium model. It’s designed to let users experience the full product value, lower the entry barrier, and test the impact on conversion rates.
The branding page was created as an MVP to test the success of our new product strategy: helping users build their brand. It gives them an overview of their brand personality, visual identity, and website assets.

Publishing flow
Publishing flow
Previously, Copyfolio sites were published automatically. With the introduction of the free trial, a manual publishing flow was designed as the main conversion point, requiring users to upgrade before their site goes live.
Copyfolio uses a freemium model, but research showed users weren’t sure which features were Premium. This page lists all Premium features, highlighting the unused ones to help them understand the value they are paying for.
