AI Chatbot Cost: Know What You’ll Pay

Free

Free costs EUR 0. It includes a one-time allowance of 30 AI conversations, one agent and one team member. The plan includes a website widget, helpdesk inbox, basic analytics, up to 2 MB of knowledge across up to 10 sources, and a momo badge on the widget. The conversation allowance is one-time, not a monthly refill. Each conversation can hold up to 10 AI replies on Free. The listed plan facts do not establish an additional seat or usage charge, so do not assume an overage price.

Starter

Starter costs EUR 29 per month or EUR 319 per year. Yearly billing is 11 times the monthly price. It includes 500 AI conversations per month, one agent and two team members. The available channels are website widget and email. The plan also includes the helpdesk inbox, Help Center, basic analytics, and 20 MB of knowledge across up to 50 sources. Paid-plan conversations can hold up to 25 AI replies. There is no momo badge on the widget. No add-on, extra-seat or overage price is specified in the plan facts.

Growth

Growth costs EUR 129 per month or EUR 1,419 per year. It includes 2,000 AI conversations per month, three agents and five team members, plus the Slack channel, API, Zapier and webhooks. It also includes advanced analytics and 100 MB of knowledge across up to 200 sources. Paid conversations can hold up to 25 AI replies. The plan details list no separate fee for additional seats, overages or add-ons; confirm any costs beyond the listed plan before budgeting.

Scale

Scale costs EUR 399 per month or EUR 4,389 per year. It includes 6,000 AI conversations per month, ten agents and ten team members. It includes API, Zapier and webhooks, advanced analytics, and 500 MB of knowledge across up to 1,000 sources. Paid conversations can hold up to 25 AI replies. The plan facts do not list a separate add-on or overage price.

The helpdesk inbox is included on every plan, including Free. A conversation beyond the included allowance does not have a stated overage price in these plan details; ask about terms before budgeting for extra volume.

What to check before choosing a plan

Start by separating the recurring software fee from the work needed to put a support desk into use. The plan fees above describe the hosted software and its listed limits. They do not provide a setup estimate, an extra-seat rate or a price for conversations beyond an allowance. Treat those as questions for the vendor, rather than filling gaps in the budget with assumed rates. If you are comparing a custom option, also account for implementation and ongoing maintenance in the comparison; a quoted software fee alone may not describe the full cost.

Next, estimate the workload you expect the AI to handle. Compare that estimate with the plan’s AI-conversation allowance, and check how conversations are defined before comparing plans from different providers. The included allowances are 500 per month on Starter, 2,000 per month on Growth and 6,000 per month on Scale. Free includes a one-time allowance of 30, not a monthly refill. The reply limits differ too: Free conversations can hold up to 10 AI replies, while paid-plan conversations can hold up to 25. These limits help describe what the plan includes, but do not establish an overage price.

Then check who needs access and what each person does. Team-member and agent limits are separate: Starter lists two team members and one agent, Growth lists five team members and three agents, and Scale lists ten of each. Match those limits to the people who need the inbox and to the agents who will handle support. For a solo user, Starter’s one-agent limit may fit; for a five-person team, Growth matches the team-member count but includes three agents. Scale lists ten team members and ten agents. These are included limits, not a promise that every team will need the same plan.

Finally, compare the channels and working tools against your support workflow. Starter lists the website widget and email. Growth adds Slack, API, Zapier and webhooks; Scale includes API, Zapier and webhooks. All plans include the helpdesk inbox, and a human teammate can take over a conversation live. Knowledge limits also differ: Free includes up to 2 MB across up to 10 sources, Starter 20 MB across up to 50, Growth 100 MB across up to 200, and Scale 500 MB across up to 1,000. Think about the content you can provide and keep current before choosing based on capacity alone.

A practical estimate therefore uses the same checklist for each option: recurring fee, usage definition and allowance, people limits, channels, knowledge capacity, and any confirmed implementation or extra charges. This also helps answer the related question of how much it costs to build a chatbot: a custom build should be compared with SaaS using its implementation and maintenance needs as well as its recurring fee.

Estimate the software fee for your team

These examples use plan fees and included team limits only. They do not add an estimated setup charge, model bill or unlisted overage. The plan facts give no separate model-usage price for the hosted plans, and no extra-seat price, so the totals below do not invent either.

Solo user: Starter supports one agent and two team members. The software fee is EUR 29 for a monthly billing month, or EUR 319 for a year billed annually. The annual fee is not the same as paying the monthly price for twelve months.

Five-person team: Growth includes five team members and three agents. Its software fee is EUR 129 per month, or EUR 1,419 per year with annual billing. The five-person fit is based on the plan’s team-member limit; check that the number of agents also fits your workflow.

Ten-person team: Scale includes ten team members and ten agents. The software fee is EUR 399 per month, or EUR 4,389 per year with annual billing.

For a growing team, take the Growth example: five team members, up to three agents, and an allowance of 2,000 AI conversations per month for EUR 129 monthly or EUR 1,419 annually. First check whether the team’s expected usage fits the allowance. Then check how handoffs reach the inbox and whether the listed channels match the support workflow. If the team needs more agent access or conversation capacity, compare Scale’s included limits with the Growth plan rather than assuming an extra-seat or overage rate.

When the plan fee can make sense

A recurring fee is easier to budget when the included usage matches the work and the team can handle conversations that need a person. With momo, the AI uses the business’s own content, drafts an answer and checks it against those sources. When it is confident, the answer goes out with citations; below its confidence line, it says it is not sure and opens a ticket for the team. That means the human inbox remains part of the workflow, not a separate resolution charge.

Whether the fee is worthwhile depends on your support volume, the content you can make available, and the time your team spends maintaining it. Track actual conversations and unresolved questions, then compare that workload with the plan limits and the hours needed to keep answers current. Do not count every conversation as a fully automated resolution.
