Where the difference shows in daily work
Two platforms with a Swiss angle, four points where the paths diverge.
Broader model choice instead of an open stack
Custodos offers a choice of the models from OpenAI, Anthropic, Google and Mistral. Swisscom combines open models with the Swiss model Apertus, without the proprietary models of the international providers.
Two AI regions instead of one
Swisscom processes and stores entirely within Switzerland, according to its own statements. Custodos also stores in Switzerland and additionally offers the EU for AI processing, for organisations with clients on both sides of the border.
A price per head instead of a package
Custodos charges a fixed seat price per user. Swisscom tiers packages by a user ceiling, the actual cost per head depends on how fully a package is used.
Cut to three legal systems
Custodos names § 203 of the German Criminal Code, § 121 of the Austrian Criminal Code and Art. 321 of the Swiss Criminal Code as the provisions for professional secret holders. This reference is not stated on the Swisscom pages checked.
- When you need models from several makersGPT, Claude, Gemini and Mistral are all available in the same workspace. Swisscom relies on open models plus the Swiss model Apertus.
- When you also process in the EUOrganisations with clients or offices in the EU choose the region case by case, the Swiss AI Assistant processes entirely within Switzerland according to the provider.
- When a price per head matters more than a packageThe Custodos seat price follows your actual number of users. With Swisscom you pay for a package with a fixed user ceiling, regardless of how many seats you actually need.
Custodos supplies the technical preconditions for handling your data confidentially. The legal assessment in each individual case remains with your organisation.
What speaks for the Swisscom Swiss AI Assistant
The Swiss AI Assistant stands for a consistent approach, and that deserves to be said here. Swisscom processes and stores data entirely within Switzerland, according to its own statements, and brings the infrastructure experience of a large Swiss telecommunications and cloud provider. If your organisation must process exclusively in Switzerland and open models are sufficient for you, the Swiss AI Assistant is a serious option.

Frequently asked questions
What separates Custodos and the Swisscom Swiss AI Assistant most clearly?
The choice of model and the pricing model. Swisscom combines open models with the Swiss model Apertus and processes entirely within Switzerland. Custodos offers the models of OpenAI, Anthropic, Google and Mistral, also stores in Switzerland and processes in the EU or in Switzerland. On cost, Swisscom bills packages by user count, Custodos a seat price per head.
Is the Swisscom Swiss AI Assistant GDPR-compliant?
Swisscom markets the Swiss AI Assistant as a privacy-friendly alternative, a literal citation of the GDPR or the revFADP is not found on the pages checked. The revised Swiss Federal Act on Data Protection has been in force since 1 September 2023, and since 15 January 2024 the European Commission has confirmed an adequate level of data protection for Switzerland. Whether your specific deployment complies with the GDPR and revFADP depends, as with any platform, on your own assessment.
What does the Swisscom Swiss AI Assistant cost?
Swisscom lists three packages, Essential at CHF 149 per month for up to 10 users, Professional at CHF 399 for up to 40 users and Premium at CHF 799 for up to 100 users, each excl. VAT, plus a custom offer for larger organisations. Custodos, by contrast, charges a seat price of €12 to €72 per user per month billed annually (€15 to €90 monthly) in euros.
Does Custodos also offer exclusively Swiss hosting like the Swiss AI Assistant?
For storage, yes: your data is held in Switzerland. You choose AI processing per workspace: the EU or Switzerland. Anyone who also needs processing exclusively in Switzerland sets the region to Switzerland.
Can I move from the Swisscom Swiss AI Assistant to Custodos?
Yes. Switching makes most sense if you need models from several makers, also need to process in the EU alongside Switzerland, or want a seat price instead of a package with a user ceiling. We will walk through the migration with you.
