Self-improving
Opening experiments run for you.
Smartsupp pairs a low-cost live chat with Mira, an AI assistant built for online stores that can even write your welcome message for you. Darwin is a website chat for booking meetings that writes, tests and replaces its own openings. Here's how they compare.
Opening experiments run for you.
Your website becomes your starting point.
Try Darwin with included bookings.
Run a small online shop and want cheap live chat with an AI that has read your product feed? That's who Smartsupp is for. Darwin exists for a different problem. When the chat's job is to land a sales meeting, someone has to keep improving the opening line, and with Darwin that someone isn't you. The rows below compare the two on automation, setup and price.

Low-cost live chat with an AI shopping assistant for online stores.
It can. Smartsupp's AI Welcome Message gives you two choices, write the greeting yourself or let the AI shape one from context, and you pick when it fires, for instance after a visitor has been on a page for a while. Darwin drafts your first opening too. The difference is what happens next: Darwin keeps writing new openings and testing them against the current one, page by page.

This is a comparison of documented capabilities, not a hands-on benchmark. “Not documented” means the reviewed sources do not establish that capability; it does not prove absence.

Setup means preparing a draft, not automatically installing it.
