What does an AI chatbot for your website cost?

Search for what an AI chatbot costs and you find wide ranges from 500 to well over 10,000 euros, with a quote request standing in for the real figure. That makes sense: most pieces about chatbot costs are written by parties who only name their own price in the sales conversation. For the record, there is a demo button at the bottom of this article too. The difference is that our figures are already above it.

Below are the real figures from the market, the places where the hidden costs sit, and our own prices. One thing first about the word chatbot: everybody searches for it, so we use it here too. We ourselves sit in a different category, the AI search function: answers from your own content, with the source included with every answer. That distinction explains further down exactly why the prices vary so much.

Two routes, two price tags

• Have one built

  From € 8,000

  One-off, for a custom AI-driven chatbot. With integrations and bespoke features it runs to well over € 25,000.

• SaaS tool

  From around € 30 per month

  A subscription with a monthly limit. The limits and your volume decide where you land; plenty of tools count per conversation or message.

Route 1: having a chatbot built

Development agency Mobilions is one of the few agencies publishing concrete budget figures: a rule-based chatbot costs 2,000 to 8,000 euros, an AI-driven version 8,000 to 25,000 euros, and a custom build with integrations to a CRM for instance starts at 25,000 euros (in Dutch). That is the build. After that come the monthly costs for hosting, the AI model and maintenance, and those move with the number of conversations.

That 25,000 euros is a starting point, not a ceiling. As soon as the AI has to do more than answer questions, it becomes a full software project and the total can end up a multiple of that. Think of connections to internal systems, bespoke widgets, or tasks the AI carries out on its own. Which makes sense: you are having your own application built, and it gets exactly as clever as your situation demands. What becomes possible once AI can also do things is a story in itself. This article is about the layer where nearly every organization starts: answering questions from your own content.

For that investment you get something that fits exactly. The flip side is that every change goes back through the builder, and that you are responsible for what runs. If you want to know what a project like that involves technically, read what it takes to start with RAG systems.

Route 2: a SaaS tool on a subscription

The entry point is far lower here: most tools start at a few tens of euros per month for a limited bundle of messages or conversations, and run up to several hundred euros per month at larger volumes. International tools often add usage costs on top of the subscription for the heavier packages, and bill in dollars.

The subscription amount is rarely the whole story here. The limits determine what you actually pay: go over your bundle and you pay extra or have to move up a package. And a chatbot that works well is exactly the one that gets more conversations every month.

Where you land in that range depends on two things: how many questions you get, and what the answers have to be able to do. A generic chatbot for a small website sits at the bottom. An organization wanting to answer thousands of questions a month from its own content, with a source alongside every answer, sits at the top or above it. So don't count on the entry rate of any tool, ours included.

What the bill really consists of

Four items determine the real cost, and three of them aren't on the pricing page.

1. The billing unit

Per conversation or per message: it sounds like a detail, but it decides whether your bill is predictable. With billing per conversation, a busy quarter, a campaign or simply success means a higher invoice. Always ask what happens the moment you go over the limit: does the chatbot stop, do you pay extra automatically, or does someone call?

2. The setup

With a custom build, the setup is the main cost, as above. But tools often come with an implementation project or a mandatory onboarding package for the first few months. Count that into the first year: a subscription of 79 euros a month with 2,500 euros of setup costs comes to more than three times what the bare subscription suggests in year one.

3. The content

An AI chatbot that answers from your own knowledge is as good as that knowledge. With many tools the real work starts after purchase: collecting documents and writing question-answer pairs, and then keeping it all current. Those are internal hours that appear on no quote. It makes a considerable difference when your website itself is the source: you maintain that anyway, and the tool picks up the changes automatically.

4. A wrong answer

The most expensive chatbot is the cheap one that answers wrongly. Digimonitor assessed 39 municipal chatbots and rated 312 answers: 10% were correct, 64% were wrong. Every visitor who gets a wrong answer calls anyway, or worse: acts on incorrect information. Why so many chatbots come unstuck on this and what to do about it is in our article about AI chatbots for your website.

What it costs at vragen.ai

Our prices are public on the pricing page. The entry package costs 49 euros per month for 500 answers and 500 documents. Above that sit Essential (349 euros, 5,000 answers) and Professional (795 euros, 15,000 answers); for larger volumes we make a custom price. Every package contains the complete product, including visible source citation with every answer, the insight dashboard and data inside the Netherlands. All you choose is the scale.

And to apply the honest story above to ourselves: Starter is there for one small website. Most organizations that become customers sit on Essential or Professional, simply because they get more questions. So count on a few hundred euros a month if your website gets serious traffic.

Two things in that model speak directly to the cost items above. We work with fair use instead of a meter reading: you never get a higher bill just because it was a busy month. And you can start on your own: there is no mandatory implementation project, and help getting going is something you add if you want it. You can cancel monthly at any time.

Fair is fair: there are cheaper tools, and for a small website that wants to offer a standard exchange they are often perfectly fine. We deliberately sit in the higher segment, because we make a different product: an AI search function that takes answers from your own content and shows the source with every answer. That is what you would otherwise have built as a custom project for tens of thousands of euros, and here it comes in a subscription of a few hundred euros a month. You can see how that works right away, with our own widget on our own content.

Six questions for any supplier

• What happens when we go over the monthly volume: does it stop, do we pay extra automatically, or do we have to move up a package?
• Are there setup or implementation costs, and are they mandatory?
• Who fills and maintains the knowledge, and how many of our own hours does that take per month?
• What does an extra website, language or channel cost?
• How long are we tied to the contract?
• Is the price public on the supplier's website?

That last question is a good first filter. A supplier who only names their price in a conversation sets that price based on the conversation.

Short answers

What does an AI chatbot cost on average?

A SaaS tool costs anywhere from a few tens to several hundred euros per month, depending on the number of conversations and your requirements. Having one built costs 8,000 to 25,000 euros one-off for an AI-driven version, plus monthly costs for hosting, the language model and maintenance.

What does it cost to have an AI chatbot built?

A rule-based chatbot costs 2,000 to 8,000 euros, an AI-driven chatbot 8,000 to 25,000 euros, and a custom build with system integrations starts at 25,000 euros. A project in which AI also carries out tasks or works deeply with internal systems can cost a multiple of that. On top of that come monthly costs.

Why do chatbot prices vary so widely?

The difference is in the billing unit and in what the package includes. Many tools charge per conversation or per message, which means a busy month brings a higher bill. With a custom build you pay up front for the build. And a generic conversation widget and an AI search function on your own content are different products: source citation, hosting location and management aren't included everywhere.

What does vragen.ai cost?

From 49 euros per month for 500 answers and 500 documents, up to 795 euros per month for 15,000 answers.

Every package contains the complete product, can be cancelled monthly and works on fair use instead of a meter reading. All the figures are on the pricing page.
