Whisper: On-Device AI

Whisper is your private, on-device AI assistant. Built for people who don’t want their data going anywhere.

Whisper runs entirely on your iPhone.

No cloud servers.
No tracking.
No data harvesting.
No “trust us” promises.

Every message is processed locally on your device using offline AI models, so your conversations stay yours - not ours, not Big Tech’s, not anyone’s.

Why Whisper is different...

• Fully offline AI: everything happens on your iPhone hardware.

• No accounts, no sign-ups, no data collection.

• No internet required for core chat features.

• Fast, responsive, low-energy models optimised for Apple devices.

• Built for privacy from day one, not bolted on later.

Use Whisper for anything

• Ask questions, learn faster, or get help thinking things through.

• Rewrite emails and messages without sending your data to a server.

• Brainstorm ideas, plan your day, or get instant explanations.

• Create drafts, summaries, and notes... privately.

Whisper is made for people who want the power of AI without giving up control of their digital life.

If you care about:

• Privacy

• Security

• Offline capability

• Zero data retention

• Owning your conversations

…Whisper is built for you.

Whisper will never rely on ads, profiling, or data extraction. Your device is your intelligence engine - we simply give you the tools.

Open Source & Verifiable

Whisper’s codebase is publicly available under a Fair Source license. Anyone can inspect the code to verify what we promise: your conversations stay on your phone and never touch our servers.
