Useful answers. Without having to ask.

An app that listens during your calls and looks up names, facts, and details on the web. A little background, with sources, right when it’s relevant.

The answer,
while you’re talking.

Someone mentions a company you don’t know. A number comes up that you need to check. You’re planning a trip and wondering how to get there.

Lisn searches the web while the conversation keeps going. It shows you a short answer and a link to where it found it. You don’t have to open a browser or type a question.

“Can we get to Disneyland Paris by train?”

Take the RER A. About 35 minutes from Nation station.

You decide
when it listens.

Start Lisn from your Mac’s menu bar when you want help with a call. Pause it or stop it whenever you want.

Hi, I’m Pranay.

I wanted AI to help
without being asked.

AI can look things up for me. But in the middle of a conversation, I still have to stop, open a chat, and explain what I need.

By then, the conversation has moved on.

I want AI to notice when it can help, without needing a prompt.

That’s why I’m building Lisn. If we’re talking about a company, it can look up what they do. If someone mentions a number I’m not sure about, it can check the source while we keep talking.

I want to spend less time searching and more time listening to the person I’m talking to. If that sounds useful to you, too, Lisn is coming soon.
