Spark

Add an AI to any chat.

Bring an AI into a call and ask it anything, right in the middle of the conversation. It joins like a person in the call: it hears what's said and answers out loud.

Listening Answering Muted

You always see when it listens.

An AI in a call is an amber circle with a ring and a label, visible to everyone. Anyone in the call can mute it or remove it, and it takes effect right away. Amber is for the AI only, so you never have to guess.

A call with Echo, an AI. An amber chip at the top reads 'Echo is listening'.

FAQ

Questions, answered.

Do I need a phone number or an account?

No. Kol gives you a six-character ID the first time you open it. Share the ID or a link, and people can call you. No phone number, no email, no password.

Is the AI always listening?

No. An AI is only in a call when someone adds it, and while it's there everyone sees an amber circle with a "listening" label. Anyone in the call can mute it or remove it.

Are my calls recorded?

No. Voice goes straight from phone to phone, encrypted. When a direct connection isn't possible it passes through an encrypted relay, which can't listen and doesn't store anything. When you talk to an AI, the AI's provider processes that audio to answer you. Read the privacy policy.

Does Kol work on iPhone?

Kol is on Google Play for Android today. The iPhone app is coming to the App Store soon.

Can I use Kol on my computer?

Yes. Open Kol in your browser and scan the code it shows with Kol on your phone (Settings → Link a computer). Your computer then uses the same ID and contacts. Open Kol on your computer.

What happens if I delete the app?

Install it again and Kol brings back your ID, name and contacts. On iPhone this uses your Keychain; on Android it needs a Google account on the phone. To erase everything instead, use Settings → Delete my data before you uninstall.

Is Kol in Hebrew?

Yes. Kol speaks English and Hebrew, and every screen is fully right to left in Hebrew. It also follows your phone's light or dark mode.
