A Swiss studio building with AI

Useful things.
Built with AI.

We turn everyday problems into tools you can use. From sharing files more privately to understanding AI compute, this is where our projects come together.

Built with AI. Designed for people.

02 / Behind the tools

A small studio.
A hands-on approach.

AI is part of how we build: research, design, code and iteration. We choose the problems, review the work and keep improving what goes live.

01 / Start with a need

Something worth solving

A file with hidden metadata. A calculation that needs clarity. A sign-in that won’t work. Each product begins with a concrete task.

02 / Build with AI

From idea to working software

We use AI to explore options, prototype interfaces and write code. Product decisions and the final review stay with us.

03 / Check and improve

Care after the first release

We check important user journeys, link to sources where facts matter and use feedback to decide what to improve next.

Built with AI describes our process. Each product explains its own features, data handling and limitations.

03 / Websites for Swiss businesses

Local business.
A clearer website.

Alongside our products, we refresh one-page websites for Swiss small businesses. Make your services easy to understand and the next step easy to take.
