On-device AI · iPhone 15 Pro+

The friend who
never tells

A personal AI companion that runs entirely on your iPhone. Your conversations never leave your device — not because we promise it, but because there are no servers to send them to.

Hush
What's been weighing on you lately?
I keep second-guessing the decision I made last month.
Hush
What's the part you keep replaying? The choice itself, or how people reacted?
The choice. I think I knew better.
Hush
Then the useful question isn't why you did it — it's what you'd need to decide differently next time.

How it works

A companion built on
real privacy

No moderation filters, no conversation logs, no cloud. Just you and an AI that actually listens.

01

Open and talk

No sign-up, no onboarding form. Open the app and start a conversation. Hush picks up where you left off.

02

It remembers you

Hush builds a private picture of your life — your work, relationships, recurring themes — and uses it to give better answers over time.

03

Get honest answers

No hedging, no deflection. Hush leads with the useful answer, not validation. The hard questions get real responses.

Features

Built for conversations
you can't have anywhere else

Because some things should only ever be said to someone who can't repeat them.

🧠

On-device AI model

Gemma 4 runs via Apple's MLX framework on the A17 Pro chip or newer. Every word the AI generates happens on your silicon — zero network calls.

💬

Persistent memory

Hush builds a private picture of you over time — your context, your patterns, your history. Stored locally. Resets instantly from Settings.

🤐

No account required

Nothing to sign up for. No email, no password, no profile synced anywhere. Open the app and start talking.

✈

Works offline anywhere

After the one-time model download (~1–2 GB), Hush works with no internet connection at all. Private even on a plane.

Privacy

What you say stays
with you

We didn't build a policy to protect your privacy. We built an architecture where data collection is technically impossible. There's nothing to breach.
