More questions? Write to us.Why Custodos instead of ChatGPT?
Custodos does everything ChatGPT does, and more: you have access to leading models from several providers and pick the best one for each task. The decisive difference is data protection. Your data is stored in Switzerland, processed by the AI models in the EU or Switzerland, never used to train models and stays under your control. On top of that you get central administration, permissions and billing for the whole team.
Which AI models are available?
Custodos bundles the leading models from providers such as OpenAI, Anthropic, Google and Mistral and adds new ones as they become available in the EU or Switzerland. You choose the model yourself, or let Custodos pick the right one for your request automatically.
Where is our data stored?
In Switzerland. Accounts, chats, files, the Company Brain and backups are stored in Switzerland. The AI models process them in the EU or Switzerland – your administrators choose the region. TLS for all connections; AES-256 for the pseudonymisation vault, stored keys and connected accounts. Your content is never used to train AI models.
Is Custodos GDPR- and revFADP-compliant?
Custodos is designed for the requirements of the GDPR and the revised Swiss Federal Act on Data Protection, and we provide a data processing agreement (DPA). Whether your use meets those requirements is for your organisation to assess, and we support you with documentation for your review. The platform is specifically designed for professions bound by statutory secrecy.
How quickly can we start?
Straight away: you can try Custodos free for 7 days (no credit card, no contractual commitment). For larger rollouts we support you with SSO integration, your permissions concept and training for your teams.
