GDPR-Compliant AI Chatbot in Europe 2026: EU AI Act, Schrems II and What to Check

If you're a European business comparing AI chatbot platforms in 2026, you'll want a GDPR-compliant AI chatbot, and nearly every vendor says theirs is. What sits behind that claim varies a lot. Some vendors are EU companies hosting in Europe, others are US companies that offer EU hosting as an option. In this article we explain what to check, what changes with the EU AI Act from August 2026, and how several vendors compare.

Disclosure: SimplyBoost is one of the platforms covered here. I'm Santhul Joseph, AI engineer at SimplyBoost in Utrecht. The company is registered with the Dutch Chamber of Commerce under KVK 87456346, which you can check in the Dutch business register. This isn't legal advice.

What a GDPR-compliant AI chatbot means in 2026

GDPR compliance isn't a label a tool has or doesn't have. It depends on how you use the tool as well. Still, there are six things worth checking with any vendor that calls itself GDPR compliant.

• Where data is stored. In which country or region customer conversations are kept.
• Who the legal entity is. Whether the company processing your data is based in the EU or elsewhere, and which laws it's subject to.
• A data processing agreement. Article 28 of the GDPR requires one. If data leaves the EU, you also need a transfer mechanism such as the EU Standard Contractual Clauses or the EU-US Data Privacy Framework.
• Sub-processors. Which other companies handle the data, including the AI model provider, and how you're told about changes.
• Retention. How long conversation data is kept, and whether it's deleted automatically.
• Data subject requests. How you handle a customer who asks to see or delete their data.

Schrems II and the CLOUD Act: why location isn't the whole story

In 2020 the Schrems II judgment struck down the EU-US Privacy Shield. Its successor, the EU-US Data Privacy Framework (2023), was upheld by the EU General Court in September 2025, and an appeal is now pending before the Court of Justice. Separately, the US CLOUD Act lets US authorities request data from US companies, wherever that data is stored. So for a US-based vendor, EU hosting is useful but doesn't settle every question, which matters most in sensitive sectors like healthcare, finance and the public sector.

An EU company hosting in Europe takes away part of that concern. It's still worth asking every vendor, EU-based or not, which sub-processors they use. Many AI tools, European ones included, rely on large model providers from the US.

EU AI Act: what applies to chatbots from 2 August 2026

The transparency rules in Article 50 of the EU AI Act apply from 2 August 2026. For chatbots, the main point is simple: people must be told they're talking to an AI system, unless that's already obvious, and at the latest when the interaction starts. In practice, this is what it means for you.

• Say it's AI. Put a clear line in the welcome message or the first reply, for example "I'm the AI assistant for our shop".
• Know your use case. A customer service chatbot usually falls under these transparency rules. Uses in areas the Act lists as high-risk come with heavier obligations, so check if that applies to you.
• Make a person reachable. It isn't the core of Article 50, but an easy route to a human is good practice and fits the spirit of the Act and the GDPR.
• Keep records sensibly. Conversation logs help you check what the bot said, but they are personal data too, so set a retention period.

EU-based AI chatbot platforms to consider in 2026

These are companies based in the EU. SimplyBoost comes first because it's the one we'd recommend to most businesses: a Dutch company hosted in Europe, with a data processing agreement, and one AI agent for website chat, WhatsApp and Instagram at a flat monthly price. Always check the details in each vendor's own DPA and sub-processor list. We compare more options on our EU AI chatbot comparison page.

SimplyBoost (Utrecht, Netherlands, and yes, this is us)

A Dutch company (KVK 87456346), hosted in Europe, with a data processing agreement available. Conversations are deleted automatically after 360 days. AI answers are generated with Google Gemini. The agent answers only from the sources you add, and you can put an AI disclosure in the welcome message and instructions. Flat pricing from €39 to €169 a month. Read about our DPA or see AI chatbot for European companies.

Watermelon (Utrecht, Netherlands)

A Dutch company building AI agents for customer service, with a focus on bringing channels into one overview. Plans range from a free tier with 50 conversations to Business at EUR 399 a month for 1,000 conversations. A good fit for Dutch businesses that want a local vendor. Compare SimplyBoost and Watermelon.

Userlike (Cologne, Germany)

A German live chat and messaging platform with chatbot and AI features and a strong GDPR focus. It's popular with businesses in German-speaking countries. Compare SimplyBoost and Userlike.

Crisp (Nantes, France)

A French company with a polished messaging platform for small businesses. Crisp says its data is held on servers in the EU. Plans are priced per workspace, from a free plan (without AI) to Plus at $295 a month. Compare SimplyBoost and Crisp.

Sleak (Netherlands)

A Dutch AI agent builder with a clear focus on Dutch-speaking customers, which makes it a natural option for businesses that mainly serve the Netherlands. Compare SimplyBoost and Sleak.

US-based vendors with EU hosting options

Several well-known vendors are US companies, and some of them let you host data in the EU. That helps, but the CLOUD Act question above remains. For many small businesses with low-sensitivity data that's acceptable. In regulated sectors, it's worth discussing with your data protection officer.

• Intercom (now called Fin). Offers regional data hosting, with EU data in AWS Dublin. Some billing and admin data can still leave the region. Salesforce completed its acquisition of the company in September 2026.
• Chatbase. A US company. Ask directly where data and model processing take place for your plan.
• Zendesk. A US company with data location options. Check whether its AI features process data in the same region as the rest of your account.
• Drift. Being wound down. In March 2026 Clari and Salesloft announced the sunset and are referring customers to 1mind, so plan a move if you use it today.

Five questions to ask every vendor

1. Where exactly are customer conversations stored? Ask for the country or region, not just "EU available".
2. Which legal entity processes the data, and where is it registered? Check the business register yourself.
3. Is there a ready-to-sign DPA, and if data leaves the EU, which transfer mechanism covers it?
4. Which sub-processors do you use, including the AI model provider, and where does model processing happen?
5. How do I tell customers they're talking to an AI, as Article 50 of the EU AI Act requires from 2 August 2026?

FAQ

Can a US-built AI chatbot be GDPR compliant for regulated industries in the EU?

It can, with the right contracts and transfer mechanisms, and many organisations do use them. The CLOUD Act is a question that EU hosting alone doesn't answer, though. Healthcare, financial and public-sector organisations often prefer an EU-based vendor for that reason, but they should still check that vendor's sub-processors.

What changes for chatbots on 2 August 2026?

From that date the transparency rules in Article 50 of the EU AI Act apply. If people interact with an AI system, they must be told so, unless it's obvious, at the latest at the start of the interaction. Chatbots already running before that date need to meet the rule as well.

Can I move from a US vendor to an EU vendor during my contract?

Usually, yes, although your contract terms decide when you can stop paying. Most teams set up the new tool alongside the old one, add their website and documents to it, and then switch the widget or channel over. Conversation history rarely moves cleanly between vendors, so export what you need to keep. Our overview of EU AI chatbots can help you pick.
