More meetings. Less managing.
HubSpot gives you free live chat inside your CRM and an AI customer agent on its Professional tiers. Darwin is built for one job: turning website visits into booked meetings, and getting better at it. Here's how they compare.

THE SIDE-BY-SIDEThe difference,
The difference,
at a glance.
Most teams already on HubSpot should probably stay there for chat, since it comes with the CRM they're paying for anyway. The case for Darwin starts when the chat window itself needs to produce meetings, not just answer questions. That's the lens for the tables below.

THE DARWIN DIFFERENCE
Your chat works on getting better.
Darwin keeps trying new openings on the pages you allow it to, and it keeps the ones that get visitors talking and booking. You don't run the tests. You just show up to the meetings.

A LITTLE MORE DETAILBefore you

make the move.
Is HubSpot's chat free?
Can HubSpot's chatbot book meetings?
They both can, in different ways. In HubSpot, a chatbot's Book a meeting action pastes a meetings link into the conversation, and the customer agent can hand a qualified lead that same link. Darwin doesn't paste a link so much as offer a slot, then finish the booking in the scheduler you connected during setup. Whichever you use, ask your scheduling provider how it records a completed booking, because that's the number your reports will show.
61114Does HubSpot test different chat openings?
Should I use Darwin instead of HubSpot?
Keep HubSpot if it's your CRM, and add Darwin on top. Darwin runs the website conversation and gets the meeting booked. Your contacts, deals and support tickets stay in HubSpot where they already live. There's really only one reason to drop HubSpot's own chat, and that's if booked meetings matter more to you than having every tool under one roof.

Published by Darwin, using the official documentation linked below. 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. HubSpot prices are per seat and the customer agent is billed in credits; a resolved conversation is not a booked meeting. Promotional prices shown on HubSpot's pricing page can change. Setup means preparing a draft, not automatically installing it.
