Comparison
Anthropic's Claude is among the best models on the market, but it is a proprietary AI hosted in the United States. Helix takes another path: the best open-weight models (Llama, Mistral, Qwen, DeepSeek…), which now rival Claude, deployed on your own machines. The same power, without depending on the goodwill of an American provider.
In 2025, Anthropic cut off xAI's access to its models overnight, for a breach of terms of use. The message is clear: an American provider can unplug a customer whenever it decides. Building your critical processes on revocable access is an operational risk.
Anthropic is an American company: data processed by Claude, even under an Enterprise contract, remains legally accessible to US authorities. For legal, healthcare or finance, that is a dealbreaker.
Claude for analysis, ChatGPT for writing, another tool for meetings: subscriptions pile up and your sensitive data scatters across several operators, each with its own terms.
The criteria that matter for a European company.
| Helix | Claude Team / Enterprise | ChatGPT Enterprise | |
|---|---|---|---|
| Location of your data | Your servers or EU private cloud | Anthropic cloud (US company) | OpenAI cloud (US company) |
| Exposure to the Cloud Act | None on-premise | Yes | Yes |
| Risk of unilateral shutdown | No: multi-model + local fallback models | Yes (xAI precedent, 2025) | Yes |
| Self-hosting / air-gapped | Turnkey, in 1 day | Impossible | Impossible |
| Available AI models | The best open-weight models (Llama, Mistral, Qwen, DeepSeek…) | Anthropic only | OpenAI only |
| Desktop app (Cowork and Code modes) | Yes, data processed within your perimeter | Yes (Anthropic cloud) | Yes (OpenAI cloud) |
| Secure agents and automations | Yes, with human validation on outgoing actions | Anthropic cloud agents | OpenAI cloud agents |
| Meeting transcription | Included, unlimited from the Pro plan | Not included | Not included |
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 and can restrict access to its services, 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.

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.
No, and that is deliberate. Claude is a proprietary AI from Anthropic that can only run in Anthropic's cloud, in the United States. Helix deploys only open-weight models (Llama, Mistral, Qwen, DeepSeek…) on your own machines or private cloud. These open models now rival Claude on most tasks, with a decisive advantage: your data never leaves your walls.
In 2025, Anthropic cut off xAI's access to its models overnight, for a breach of terms of use. The message is clear: a proprietary AI provider can unplug a customer whenever it decides. With open-weight models deployed on your side, no one can cut off access: the service runs on your infrastructure.
Anthropic does take confidentiality seriously, but it remains an American company subject to the Cloud Act, and your data passes through its cloud. Contractual confidentiality is not the same as technical sovereignty. With Helix the question disappears: the data never leaves your perimeter, there is no third party to trust.
Yes. Helix includes a Code mode: code generation and execution in a secure sandbox (scripts, data analysis, prototypes), plus a Cowork mode where the AI works on your real files from your machine. That is Helix's ambition: a complete platform in the spirit of Anthropic's, but sovereign and deployed locally, with open-weight models.
Rather than a per-user subscription that climbs with the number of seats, Helix deploys on your infrastructure and brings chat, code, agents and transcription into a single platform. The cost depends on your installation; we quote it after a free assessment of your usage.
