What is Stay4S?

Stay4S is a Dutch AI platform. You chat with the models we host, use focused AI tools and deploy agents and dashboards for recurring work. Developers get an OpenAI-compatible API with credits.

The platform is for individuals and small teams who want to start without a technical setup, and for developers who use the same models through the API. You start with an account; then you choose a service or plan.
