Comparison
ChatGPT is an excellent product, but your company data deserves better than passing through the servers of an American company subject to the Cloud Act. Helix deploys the best open-weight models (Llama, Mistral, Qwen, DeepSeek…) on your own machines or private cloud: the power of AI, with sovereignty on top.
OpenAI and Microsoft are American companies: the Cloud Act lets US authorities demand access to the data they process, wherever it is hosted. For regulated sectors, that is a dealbreaker.
Contracts, strategy, source code, customer data: every prompt sent to a cloud AI exposes sensitive information to a third party, with limited traceability on the company's side.
ChatGPT Enterprise only gives access to OpenAI's models. To also get Claude, Gemini or Mistral, you have to stack subscriptions, scattering budget and data.
The criteria that matter for a European company.
| Helix | ChatGPT Enterprise | Microsoft Copilot | |
|---|---|---|---|
| Location of your data | Your servers or EU private cloud | OpenAI cloud (US company) | Microsoft cloud (US company) |
| Exposure to the Cloud Act | None on-premise | Yes | Yes |
| On-premise / air-gapped deployment | Turnkey, in 1 day | Impossible | Impossible |
| Available AI models | The best open-weight models (Llama, Mistral, Qwen, DeepSeek…) | OpenAI only | OpenAI via Microsoft |
| Local open-source models | Yes, on your hardware | No | No |
| Connection to your tools (Drive, Notion, Slack…) | Native, local indexing | Partial | Microsoft ecosystem |
| Meeting transcription | Included, unlimited from the Pro plan | Not included | Via Teams only |
Comparison made in good faith as of the publication date; vendor offerings evolve. The structural point does not change: an American company remains subject to the Cloud Act, regardless of the hosting location.
Far more than a chat: a complete work platform, with every AI model on the market.
The AI works alongside you directly on your machine: writing, document analysis, spreadsheets, presentations, on your real files, not in an isolated tab.
Code generation and execution in a secure sandbox: scripts, data analysis, prototypes, with nothing more to install.
Build agents that run your recurring processes autonomously and securely, with human validation at critical steps.
Your meetings transcribed, summarized and usable by the AI. On-premise, the audio never leaves your infrastructure.
Drive, Notion, Slack, SharePoint... your data is indexed and searchable by every model, with role-based access control.
The same platform, deployed on your servers or our sovereign cloud in France. Your data never leaves your walls.
Discover all the features, security and pricing of Helix.
No DevOps team or pre-existing AI plan required: we guide you from diagnosis to deployment.
We analyze your current usage, your tools, your regulatory constraints and your priority use cases. You leave with a clear action plan, no commitment.
We install the platform on your infrastructure or our sovereign cloud in France, connect your data and set up your teams. Installed in 1 day.
Training for your teams, technical support with a response within 24 business hours, ongoing maintenance and updates. You are never left alone with the tool.
For the vast majority of business tasks, yes. Helix runs the best open-weight models (Llama, Mistral, Qwen, DeepSeek…), which now rival GPT on writing, document analysis, summarization and code. The difference: they run on your machines, not OpenAI's. And because Helix is multi-model, each task is routed to the most relevant model.
No, not legally. OpenAI remains an American company: the Cloud Act lets US authorities demand access to the data it processes, whatever the datacenter. European residency reduces latency, not legal exposure. Only a deployment on your own infrastructure, with open-weight models, structurally removes this risk.
No. We install Helix on your servers or private cloud in a day, connect your documents (Drive, Notion, SharePoint…) and train your teams. The interface is familiar: a chat, a Cowork mode that works on your real files, a Code mode. Your people keep their habits, in a sovereign way.
Where you would have to stack several per-user subscriptions to cover chat, code and meetings, Helix brings everything into a single platform, up to 4 times cheaper in use. Deployment is quoted after a free diagnosis, based on your infrastructure and use cases.
There is no minimum size. For a small team, we often start with a lightweight deployment on a single server or on our sovereign cloud in France, then grow the installation with your needs. The free diagnosis helps scope the right setup.
