ChatGPT and its large-language models are functional and good, but they are not designed for European data protection standards. When you want to use ChatGPT in Europe, your data is transferred to US servers. Furthermore, ChatGPT is not GDPR compliant by default. Even its paid subscription tiers need some adjustments to meet GDPR standards. Fortunately, you can solve this problem by using GDPR-compliant and EU-hosted AI platforms.
In this article, we'll discover the best GDPR-compliant ChatGPT alternatives.
TL; DR
ChatGPT is not GDPR-compliant by default, its free and even paid tiers route data to US servers and require manual fine-tuning to meet EU standards. For ready-made compliance, five EU-hosted alternatives stand out. TextCortex offers a single API for 18+ frontier and budget LLMs (including GPT-5.5, Claude Opus 4.7, GLM 5.1, and Kimi K2.6) with EU data residency, SOC/ISO certification, and native connectors like Slack and Notion. Mistral Le Chat is a European-built chatbot with web search, image generation, and Canvas editing that rivals GPT-5.5. HuggingChat hosts 100+ open models in the EU with a free tier and no training on user data. EUrouter is an API-focused gateway delivering 100+ LLMs with zero data retention and real-time observability for rapid compliance fixes.
What is ChatGPT?
ChatGPT is an AI chatbot developed by OpenAI that offers frontier models in the AI industry. In addition to its AI chatbot features, you can use ChatGPT for automation, as your personal assistant, or complete professional tasks using GPT-n models.
Is ChatGPT GDPR-Compliant?
No, ChatGPT's free tier is not GDPR-compliant and does not meet the requirements of the EU AI Act. Even if you are using ChatGPT with one of its paid subscription tiers, you need to fine-tune it to make it GDPR-compliant. Also, even if you can use the ChatGPT API as GDPR-compliant, you still need to fine-tune it beforehand. This fine-tuning process is both extra workload and time-consuming, and it can be difficult and complex if you don't know what you're doing. However, you can overcome this problem by using GDPR-compliant ChatGPT alternatives.
5 Best GDPR Compliant ChatGPT Alternatives
If you want to use powerful large language models to automate your enterprise workflow and don't want to waste time fine-tuning LLMs, we recommend using GDPR-compliant ChatGPT alternatives. Let's take a look at the best GDPR-compliant ChatGPT alternatives.
1. TextCortex AI
If you want to integrate EU-hosted large language models into your application, TextCortex is the AI gateway you're looking for. TextCortex is an open router alternative that offers frontier models like ChatGPT, Gemini, and Claude as EU-hosted and GDPR-compliant. With TextCortex AI, you can deploy frontier models like GPT-5.4, GPT-5.5, and Claude Opus 4.7 as GDPR-compliant to your enterprise. Thanks to the TextCortex API, you can use a total of 18 powerful and frontier large language models, including ChatGPT models, as EU-hosted and integrate them into your own AI models via a single API. TextCortex also offers users a wide range of connectors that they can directly integrate with, such as Slack, Notion, Confluence, SharePoint, and GitHub.
TextCortex hosts its users' data in the EU and never uses it for model training. TextCortex is SOC Type I, SOC Type II, and ISO 27001 certified and offers a monitoring service to track security.
One API to Rule Them All
With the TextCortex API, you can access models like GPT-5.5, Claude Opus 4.7, and Gemini 3.1 Pro simultaneously with a single API, without needing to purchase APIs from different providers such as ChatGPT or Anthropic. In addition to frontier large language models, TextCortex also allows access to models like GLM 5.1, KimiK2.6, and DeepSeek V4 Pro, which offer powerful performance at much lower prices but don't offer EU hosting. This allows you to choose a large language model according to your needs and deploy it to your enterprise or AI project as EU-hosted, GDPR and EU AI Act compliant.

2. GreenPT
If you're looking for a direct conversation experience alternative to European ChatGPT, GreenPT is an option to consider. GreenPT is an AI platform that offers open-source models by self-hosting them; in other words, it provides EU-hosted, GDPR-compliant Anthropic and OpenAI models.

You can use GreenPT for conversational experience, image and code generation, or as an API to develop your own app.

Mistral Le Chat is currently the most popular and the strongest European ChatGPT alternative you can find in the market. Mistral Le Chat was founded in 2023 by former researchers from Meta and Google DeepMind.
