| Side by side | Darwin | HubSpot |
|---|---|---|
| Self-improvementHow each product improves the openings that start sales conversations. | ||
| Self-improves to book more meetings | Yes Creates tests. Promotes qualifying winners. Tests again. 1 With automation enabled, on eligible pages within your plan. Tests need enough traffic; a lift is not guaranteed. | Not documented Operator-written messages; A/B tests and an autonomous opening loop are not documented. 23 HubSpot offers A/B tests for other assets. The reviewed chatbot and customer agent guides describe operator-written messages and guidelines. |
| Writes new openings for each page | Yes Creates opening variants from page context. 1 For pages with automation enabled and sufficient traffic to run an experiment. Every plan includes unlimited optimized pages. | Manual setup Chatflow welcome messages are entered by the operator and targeted to pages. 2 Personalization tokens can vary a message; the copy is not generated per page. |
| Tests and keeps better openings | Yes Tests opening variants and can promote a better performer. 1 Requires enough evidence; an experiment may have no winner. | Not documented Automatic promotion of a better chat opening is not documented. 4 The reviewed chatbot guide does not describe testing or promoting message variants. |
| Starts the next test automatically | Yes The next opening experiment builds from the current winner. 1 Automation must be enabled and the page eligible. This does not guarantee improving results. | Not documented An automatic cycle of generating, testing and replacing openings is not documented. 45 Customer agent guidelines and chatflows are edited by the operator. |
| OnboardingWhat the product prepares for you before you go live. | ||
| Learns from your website | Yes Darwin discovers the relevant pages on your website and prepares its knowledge base from them. 6 Initial setup selects key pages for speed; more pages can be imported later. | URL import The customer agent can import public website URLs and HubSpot pages as knowledge. 7 The operator adds sources under Train > Knowledge; Professional or Enterprise with credits. |
| Drafts your sales settings | Yes Prepares business information and assistant settings from the website. 6 The user can review and refine the generated draft. | Not documented Automatic drafting of qualification guidelines or business settings from the website is not documented. 58910 The operator enters guidelines and qualification criteria; tone is a preset or a brand voice generated from writing samples. |
| Matches chat to your brand | Colors & fonts Extracts brand colors, fonts and assets for the chat design. 6 Brand detection is a draft: available fonts, contrast and source-site access affect the result. | Account colors Widget colors default to the account's branding settings. 11 Brand settings are maintained in the account; fonts are picked from a dropdown. |
| Writes your first chat opening | Yes Drafts the first chat opening from the business context. 12 Drafted during assisted setup; approve it, edit it (120-character limit) or ask Darwin for a revision. | Manual setup The chatflow welcome message is entered by the operator. 4513 Customer-agent handoffs can send a predefined greeting the operator writes. |
| Review before going live | Yes The assistant draft can be reviewed and refined before installation. 12 Calendar connection, testing and website installation remain separate completion steps. | Yes Preview for chatflows; preview and test responses before deploying the customer agent. 41415 Testing is a recommended step, not an automatic gate. |
| PricingUSD, before tax. Darwin bills per credit: a meeting or qualified request. | ||
| Lowest monthly platform fee | $0/mo Free has no monthly subscription fee. 16 No card needed to start; credits are charged after the first five free ones. A credit is one booked meeting or qualified request. | $0/mo HubSpot's free tools include live chat and a limited chatbot with HubSpot branding. 17 No monthly fee for free tools; paid hubs are per seat. |
| Introductory offer | 5 free credits The first five credits are free, once. 16 A credit is one booked meeting or one request that passes your fit rules. Not a monthly allowance; a card is needed once all five are used. | Free tools Free tools are free to use; a separate time-limited trial is not listed. 17 The customer agent is not part of free tools. |
| AI usage charge | $30/credit Free charges $30 per credit after the first five. 16 A confirmed booking or a request that passes the fit rules is one credit. Conversations and leads that fail the fit rules are never charged, and there is no plan fee. | 50 credits/resolution The customer agent uses 50 HubSpot Credits per resolved conversation. 1718 Extra credits are $10 per 1,000 ($0.010 each); requires Professional or Enterprise. A resolved conversation is not a booked meeting. |
| Paid plans start at | $299/mo Growth is $299 per month on monthly billing. 16 Includes 10 credits a month. Annual billing is two months free ($2,990 a year); credits and extra-credit charges stay monthly. | $20/seat/mo Sales Hub Starter lists $20 per seat per month. 17 A promotional 'Starts at $7' price was shown at review. Starter removes branding but does not include the customer agent; Professional lists $100 per seat per month (shown from $90 at review). |
| Included on paid plans | 10–25 credits/mo Growth includes 10 credits a month; Agency includes 25, pooled across up to 200 client workspaces. 16 Unused included credits roll over for one month. Growth can also be bought with 35, 60 or 110 credits a month, and Agency with 50, 75, 125, 275 or 525. | 3,000 credits (Pro) Professional includes 3,000 HubSpot Credits; Starter includes no customer-agent usage. 1719 Credits are shared across Breeze features; 50 credits per resolved conversation. |
| Additional paid-plan usage | $8–$25/credit Extra credits cost $25 each. Choosing more credits each month lowers the rate: on Growth, $20 at 35 credits, $16 at 60 and $12 at 110; on Agency, $10 at 275 and $8 at 525. 16 Charged automatically each month at the current rate, after the monthly included credits and in addition to the plan fee. | 50 credits/resolution The customer agent uses 50 HubSpot Credits per resolved conversation. 1718 Extra credits are $10 per 1,000 ($0.010 each); requires Professional or Enterprise. A resolved conversation is not a booked meeting. |
Your first five meetings or requests are free. After that each is $30, or Growth is $299 a month with 10 included.
Facts checked Oct 5, 2026 to Oct 20, 2026. Plans and integrations can change. Not documented means the reviewed sources don’t establish a capability; it doesn’t prove the feature is missing. Sources and method
Eighty-five seconds on what Darwin does: learns your business from your site, books the meeting inside the chat, and keeps rewriting the opening until more people talk.
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.
202425Keep 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.
1421222728Published 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.
