Breakout sells an inbound AI SDR: it identifies who's on your site, nudges them with personalized content and books the meeting. Darwin books meetings from your website too, and spends its time testing which openings get people talking. Here's how the two compare.

| Side by side | Darwin | Breakout |
|---|---|---|
| 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. | Segment opener tests Visitor-personalized nudges with opener tests per segment; an autonomous opening loop is not documented. 2345 A Breakout use-case page (intro still placeholder copy) says teams run different openers per segment and keep the winner; the help center does not describe test setup or how a winner is chosen. |
| 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. | AI or written nudges Nudges can target page URLs, with copy written by the team or generated per visitor from a prompt. 456 The team sets conditions and the prompt; generating openings from page content is not described. Opener testing per segment is described on a use-case 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 opening is not documented. 456 A Breakout use-case page says teams can test openers per segment and keep the winner; how the winner is chosen is not described. |
| 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. 34 Breakout describes keeping the winning opener and continuing to test; automatic generation of new openers is not described. |
| 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. 7 Initial setup selects key pages for speed; more pages can be imported later. | Knowledge base You point the agent to your knowledge base; website crawling is not specified. 8 Instructions and knowledge base are provided by the team. |
| Drafts your sales settings | Yes Prepares business information and assistant settings from the website. 7 The user can review and refine the generated draft. | Not documented Automatic drafting of business settings from the website is not documented. 3910 The team gives the agent instructions. |
| Matches chat to your brand | Colors & fonts Extracts brand colors, fonts and assets for the chat design. 7 Brand detection is a draft: available fonts, contrast and source-site access affect the result. | Not documented Colors and styling are set manually; automatic brand import is not documented. 69 Configured in Blocks → Ask AI. |
| Writes your first chat opening | Yes Drafts the first chat opening from the business context. 11 Drafted during assisted setup; approve it, edit it (120-character limit) or ask Darwin for a revision. | AI-generated option Nudges use a written message or copy an LLM generates for each visitor from the team's prompt. 569 The chat's welcome message is set in Blocks → Ask AI; nudges can be previewed before publishing. |
| Review before going live | Yes The assistant draft can be reviewed and refined before installation. 11 Calendar connection, testing and website installation remain separate completion steps. | Yes A Playground preview, nudge previews and a hidden test deployment come before launch. 351213 Playground answers show their sources and take feedback; nudges go live with a Published toggle. |
| PricingUSD before tax. Darwin charges per credit. Breakout publishes monthly tiers with included seats; its AI SDR sits on the Growth tier. | ||
| Lowest monthly platform fee | $0/mo Free has no monthly subscription fee. 14 No card needed to start; credits are charged after the first five free ones. A credit is one booked meeting or qualified request. | $500/mo Signals starts at $500 per month. 15 Signals covers visitor and company identification; the Inbound AI SDR needs Growth. |
| Introductory offer | 5 free credits The first five credits are free, once. 14 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. | 30 day trial (Signals) A free 30-day trial without a card on the Signals plan. 151617 Trial length is stated on Breakout's blog; the pricing page offers the trial on Signals only, while Growth (with the Inbound AI SDR) is demo-led. |
| AI usage charge | $30/credit Free charges $30 per credit after the first five. 14 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. | No usage charges Breakout says AI qualification and meeting booking are unlimited, with no usage-based charges. 1819 Stated on Breakout's Intercom comparison page; plans are priced by tier and seats on annual contracts. |
| Paid plans start at | $299/mo Growth is $299 per month on monthly billing. 14 Includes 10 credits a month. Annual billing is two months free ($2,990 a year); credits and extra-credit charges stay monthly. | $2,000/mo Growth, which includes the Inbound AI SDR, starts at $2,000 per month. 815 12 seats included; Enterprise by quote. |
| Included on paid plans | 10–25 credits/mo Growth includes 10 credits a month; Agency includes 25, pooled across up to 200 client workspaces. 14 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. | 5–12 seats; unlimited bookings Signals includes 5 seats and Growth 12; Breakout says AI qualification and meeting booking are unlimited. 1819 The AI SDR and scheduling start on Growth, from $2,000 a month. The unlimited claim is on Breakout's Intercom comparison page. |
| 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. 14 Charged automatically each month at the current rate, after the monthly included credits and in addition to the plan fee. | No usage charges Breakout says AI qualification and meeting booking are unlimited, with no usage-based charges. 1819 Stated on Breakout's Intercom comparison page; plans are priced by tier and seats on annual contracts. |
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.
Breakout lists its prices, which is rarer than it should be in this category. Signals runs from $500 a month and covers visitor identification; Growth, the tier with the actual AI SDR, runs from $2,000 a month; Enterprise is a conversation with sales. There's a free 30-day trial. Darwin's Free plan costs nothing per month. You get five free credits and pay for each meeting booked or qualified request after that.
1415Yes. Breakout says it books meetings both in chat and from its Smart Forms, with pre-filled one-click calendar booking, though its pages don't name the calendar providers. Darwin offers a time in the conversation and completes the booking in whichever scheduler you've connected. With both, check what gets recorded as a finished booking.
2820Breakout personalizes nudges to a visitor's industry, size and region, which is a different idea from testing. A Breakout use-case page says teams can test openers per segment and keep the winner, though how the winner is chosen isn't described. Darwin writes opening variants for each page, tests them, keeps the better one and starts the next test.
12345Published 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. Breakout publishes monthly tiers and a public help center; several capability rows still read “Not documented” because neither describes them. Darwin bills for booked meetings. Setup means preparing a draft, not automatically installing it.
