Darwin

Darwin's most distinctive idea is a chat that experiments on itself. Each page tests competing opening messages, measures which one leads to more booked meetings, and keeps the winner, either automatically or after you approve it. That turns the greeting most teams set once and forget into something that keeps getting better over time.

• Answers buyer questions using content from your own website pages
• Qualifies visitors and books meetings or captures quote and callback requests inside the chat
• Holds back new openings that look likely to perform worse, so results do not slip
• Reports visits, conversations and meetings by page and traffic source
• Connects with Calendly, Google Calendar, HubSpot, Salesforce, Zapier, Slack and more, plus an API and MCP server

Darwin is best for B2B companies, agencies and service businesses whose website goal is a booked call or a qualified request rather than general support. Because you pay per meeting or qualified request while chats stay free, costs track outcomes. A practical tip: start on the free plan with your pricing page, where buying intent is highest, and let the opening experiments run long enough to gather meaningful data before rolling Darwin out across the rest of the site.
