How we build our apps

Private by design

We collect as little as possible and never sell data. Prompt Builder needs no account, and what you type stays on your device.

In your language

Built for everyone: Prompt Builder already speaks 39 languages, from Spanish and Arabic to Hindi, Chinese and Japanese.

Works offline

After the first visit, Prompt Builder keeps working without a connection: on a plane, on a train, or on a bad Wi-Fi day.
