What "integrating AI" means on a site
AI on a website can take many forms:
- conversational chatbot,
- sales assistant,
- recommendation engine,
- automatic lead qualification,
- dynamic content generation,
- process automation,
- 24/7 customer support.
Complexity, and therefore price, depends on what the AI has to do, not on the label.
Simple AI chatbot: €900 to €1,800
This is the most common type of integration.
Typical features:
- a conversational chatbot built on a language model (GPT, Claude or another),
- answers based on your existing pages,
- conversational form,
- capture of emails and requests,
- a simple interface.
Ideal for:
- showcase sites,
- SMEs,
- a first experiment with AI,
- basic support.
This kind of chatbot does not replace a human: it filters questions and guides visitors. The detailed costs, setup and monthly subscription, are in our article on the cost of an AI chatbot.
Advanced AI chatbot: €2,500 to €12,000
At this level the AI works as a sales assistant.
Additional features:
- CRM integration (HubSpot, Pipedrive...),
- automatic lead qualification,
- lead scoring,
- routing to the right team,
- conversation history,
- personalized answers.
Ideal for:
- B2B companies,
- sales teams,
- high-traffic sites,
- qualified lead generation.
The lower end covers simple qualification with a notification; the upper end, structured CRM synchronisation and advanced follow-up. Measure the benefit in better-qualified leads and time saved for sales, comparing before and after on your own figures.
Content personalization AI: €4,000 to €12,000
This kind of AI adapts what the site shows to the person reading it:
- business sector,
- behavior,
- where they came from (SEO, ads, LinkedIn),
- browsing history.
Examples:
- dynamic headlines,
- customized CTAs,
- page recommendations,
- contextual messages.
Its value depends on traffic: without enough volume, there is little behaviour to learn from and little effect to measure.
Business AI agents: €8,000 to €20,000
An agent goes further than answering questions.
Here the AI works as an autonomous agent that can:
- respond to complex requests,
- interact with internal databases,
- trigger workflows,
- create or update CRM records,
- manage support tickets,
- schedule appointments.
Ideal for:
- high-volume companies,
- customer support,
- advanced pre-qualification,
- lower staffing costs.
Tailor-made AI: €15,000 to €30,000 and up
Most advanced cases:
- integration with several internal systems,
- complex business rules,
- proprietary data,
- enhanced security,
- specialized models,
- multilingual support.
This kind of project is closer to software development than to web integration.

AI API (OpenAI, Anthropic, etc.)
€50 to €500 a month depending on usage.
Hosting and orchestration
€50 to €300 a month.
Maintenance and tuning
€100 to €500 a month.

Yes, if:
- you have traffic,
- you generate leads,
- you lose time qualifying leads,
- you want to improve the customer experience,
