About this app

Ondam is a private, offline AI chatbot and voice assistant that runs entirely on your phone — no internet, no account, no data ever leaving your device. A local AI you can actually talk to.

■ Offline AI, no internet needed
• Works in airplane mode, underground, on a plane, abroad — ask and answer with no signal.
• On-device AI (Gemma family). One-time model download, then fully offline. No mobile data.

■ Truly private
• Your conversations never leave your phone. No login, no sign-up, no ad tracking, no data collection.

■ An AI companion that greets you in your language
• 100+ languages. It won't force English on you.

■ Voice
• Replies are read aloud in a natural voice — free.
• Pro: live voice mode to talk like a real call, plus a premium, more natural voice.

■ Make it yours
• Set its name, personality and tone. Build your own AI friend.

Free forever — no payment, no subscription. Add more only when you want: Basic (one-time) unlocks the 4B model, read-aloud voice, custom persona and image input; Pro (subscription) adds live voice mode, the Pro model and premium voice.

Your own private AI, inside your phone. Ondam.
