Pertento is a conversion rate optimization platform that combines A/B testing, an AI-powered visual editor, and on-site surveys for websites and online stores. The AI editor lets users describe a page change in plain language and builds the variant directly on the live site, removing the need for developer involvement. It supports both frequentist and Bayesian statistical methods side by side, and all tracking runs via a single cookie-free script under 1 KB. Plans are priced per session rather than per seat, with a 12-day free trial available.
