Hey HN! I built Abee (A/B Experiment Engine) – autonomous A/B testing. It generates hypotheses based on conversion psychology, creates variations, runs the test, picks the winner, promotes it as the new control, and starts the next round. It learns what works for your audience over time – which angles (urgency, trust, social proof, etc.) actually convert. Optional approval mode lets you review variations in batches before they go live, and your feedback trains the model to match your preferences.
