Be Understood

Clearer calls on WhatsApp,
Telegram and Signal.

Hush takes the background noise out of your voice and covers brief dropouts on a weak connection. Same account, same name, a quieter call.

The difference is in the listening.

Same voice.
A little more quiet.

Put your headphones on.
Play the clip, then switch Hush on.

Outside, on a callA synthetic voice-and-street-noise example

Loading the comparison…

No cuts. Switch at the same moment.

Synthetic demonstration: generated speech and background noise processed through Hush’s Strong filter. Not a recording of a real call. Results vary.

Transcript & how this was made

The demonstration transcript will appear here when the audio is ready.

The same noisy recording is used for both versions. The filtered version is produced by the actual Hush audio filter, not a separate clean take.

More than a
quieter microphone.

One relay for the calls
you already make.

Less noise

Traffic, wind, a busy kitchen. Hush filters the background out of your voice before it reaches the other person.

Steadier on a weak signal

Hush sends backup audio with the call, so a lost packet can be rebuilt instead of cutting a word. Today that protects what you hear. The same protection for your own voice is in testing.

The apps you already use

Calls go through your own WhatsApp, Telegram or Signal account, so people see your usual name. Signal support is experimental.

A familiar call.
A quieter microphone.

No new number.
No headset to buy.

A few things
worth knowing.

Does it work with my headphones?

Use the headphones or microphone your phone or browser supports. Setup includes a listening test, so you can check your own sound before a call. Different microphones and environments give different results.

Do I keep my WhatsApp, Telegram or Signal account?

Your account stays your account. Hush connects to it as a linked device, the same way WhatsApp Web, Telegram Web or Signal Desktop does, and you make or answer filtered calls in Hush. It doesn’t filter ordinary phone calls or other apps.

Can I lock my phone during a call?

In the iPhone and Android apps, yes. Calls run like regular phone calls, so you can lock your screen. In the browser version, keep Hush open with the screen on, because switching apps or locking your phone can interrupt audio.

Will it fix a bad connection too?

It helps with short dropouts. Hush adds backup audio to what it sends your phone, so a lost packet can be rebuilt instead of cutting a word. The same protection for your own voice is in testing. When the connection is gone for whole seconds, the call still breaks up.

Is Signal supported?

Yes, as an experiment. Signal linking runs through Signal’s desktop app and may stop working when Signal changes it. WhatsApp and Telegram are the steadier choices.

What happens to my data?

The hosted linked device can access your linked account, so you need to trust the person operating Hush. It acts only when you tap Call or Answer and never reads or sends your messages. Hush does not record your calls. Call audio is encrypted in transit and filtered on the relay. You can remove the link at any time in your app’s linked devices settings.

Who can join?

This is an invitation-only beta for family and friends, with room for ten members and up to five simultaneous sound sessions. Access requests are reviewed by the organizer; requesting access doesn’t automatically create an account.
