The personal AI personality platform

AI personas that feel like someone.

Mentara gives an AI character a real voice and a personality that holds its own — then lets them speak through your one-on-one Discord calls.

Watch a persona hold a call

A real Mentara persona answering out loud in their own voice — the latency, the rhythm, the way they actually sound on a live call.

Anywhere you talk

It becomes your microphone.

Most AI is stuck in a browser tab. Mentara is an app you download — it routes a persona's voice straight into your calls, so they speak as you.
