Copy-paste our snippet into your HTML. No build process, no configuration, no SDK to learn.
AI analyzes your page and generates smart experiments: headlines, CTAs, layouts, everything.
Winning variants are automatically deployed. Your conversion rate improves every week.
Darwin works the way evolution does. Small mutations, constant testing, survival of the fittest.
Drop a single script tag on your site. Darwin starts observing immediately: clicks, scrolls, conversions, bounce rates.
AI analyses your data and generates experiments across every layer: copy, design, layout, even personalisation per visitor segment. Each mutation competes against the original.
Winners get promoted to production automatically. Losers are discarded. Your page gets better every week, without you lifting a finger.
Darwin optimises every layer of your landing page, from copy to structure to personalisation.
Test different value propositions, angles, and emotional hooks to find what resonates.
"Start free" vs "Get started" vs "Try it now." Small words, big differences.
Technical vs benefit-focused. Short vs detailed. Darwin finds the right level for your audience.
Colours, sizes, border radius, shadows. Every visual detail that influences whether someone clicks.
Font sizes, weights, padding, whitespace. The invisible factors that affect readability and trust.
Hero images, illustrations, icons. Test what visual style builds the most credibility.
Should social proof come before features? Does the pricing section convert better higher up?
Centred hero vs split layout. Grid vs list. Darwin tests structural changes, not just cosmetic ones.
Sticky nav vs static. Inline forms vs modals. Optimise how visitors move through your page.
"Welcome from Product Hunt!" Tailor the experience based on where your visitors are coming from.
Not just responsive: actually different content and layouts for mobile vs desktop visitors.
Recognise returning visitors and show them a tailored experience. Skip the intro, show what's new.

Let Darwin run fully autonomous, or keep a human in the loop. Switch anytime.
Darwin generates experiments, runs them, and promotes winners to production. No approval needed. Your page evolves on its own.
Darwin proposes experiments and shows results, but nothing goes live until you approve. Full control, zero surprises.
