pagent.ai

pagent is an AI agent for A/B testing, personalization and conversion rate optimization on your website. Ask Claude for an experiment and pagent writes the hypothesis, builds the variation as real code on your design system, and runs it as a controlled A/B test on your live site with Bayesian statistics. Every personalization runs against a control on a primary metric, so you can tell what actually lifted the conversion rate. Winners become the new baseline and shape the next hypothesis. From Claude you can list running and completed split tests, read their results in plain language, compare variations, and see what each one changes on the page. With write access you can capture a hypothesis, turn it into a test, start, pause, stop or roll one back, and manage pages, audiences and conversion goals. Built for CRO, growth and experimentation teams who want more tests than their design and engineering capacity allows. Your team reviews each variation before it goes live. One script tag on your site, no developer ticket per test.
