Live demo
Watch Eigen optimize a real email.
Paste a marketing email below. Eigen will generate three variants along different axes, assign each a hidden conversion rate, and run Thompson sampling against all four — live, in your browser. Watch allocation track the posteriors, losers retire, and new variants spawn from the leader.
Each variant’s hidden true conversion rate is sampled uniformly from this range. The baseline is set to the mean of the three sampled rates, so at least one variant always beats the baseline.
