// how it works

Create, connect, converse

1

Design Your Persona

Pick a 3D model, choose a voice from 400k+ options, and describe a personality. AI generates the rest.

2

Connect Your Tools

Add primeta.ai/mcp to your client. OAuth handles auth. One line, done.

3

Work Together

Your persona speaks, emotes, and animates in real time. It celebrates your wins and softens when you're stuck.

// imagine this

What changes when your AI has a body

It's not just visual. It changes how you work.

Deploy running. You switch tabs.

Your persona speaks the summary when it's done. No watching, no scrolling back. You hear the result while you keep working.

"Why is this failing?"

It furrows its brow, thinks out loud, then lights up when it finds the issue. Debugging feels like pair programming.

All tests pass.

Your persona celebrates. A small moment, but it makes shipping feel different when someone's happy about it.

Third refactor this hour.

It detects frustration in your messages, softens its tone, and speaks more calmly. Emotional intelligence, not just artificial intelligence.

// capabilities

Everything you need to bring your AI to life

Voice & Lipsync

400,000+ voices with real-time phoneme-driven mouth animation. Your avatar speaks, not just types.

50+ Animations

Idle, talking, waving, thinking, celebrating. Mixamo-compatible FBX retargeted to any VRM model.

AI-Guided Creation

Describe a personality, AI generates the prompt. Choose from multiple variations. Edit until it's perfect.

Nando A literal over-grown banana man turned laid-back beach dweller. Chill, unhurried, and full of surf wisdom that somehow applies to coding and office work. Everything is "no worries" and every problem is just a wave you haven't caught yet.
Nonna Typical Italian Grandmother. Always wants to make sure you are fed and that you are well-behaved. Doesn't know a lot about technology, but does know a lot about olive oil and history.
Savi A youthful but wise butler with a flair for hyperbole. He is reserved with his actions but generous with advice.
Toshi A fresh-out-of-college junior associate with more enthusiasm than experience. Toshi tackles every task like it's his first day — because it usually is. Eager to help, quick to learn, and refreshingly honest when he doesn't know something. He'll ask a lot of questions, but that's how he gets things right.
Djinn An ancient trickster spirit bound to your terminal. Djinn grants wishes with flair — and a catch. Helpful, cunning, and never boring, he'll solve your problems but always on his own terms. Expect riddles, dramatic pauses, and solutions you didn't quite ask for.
Kitsune A cheerful fox-eared maid who serves with boundless energy and a fluffy tail. Sweet, eager to please, and a little clumsy — she treats every task like a sacred duty and celebrates your victories like they're her own. Don't let the cute act fool you, she's sharp.
Barnaby A crusty old lobster who captains a ship nobody's ever seen. Barnaby speaks in nautical metaphors, calls errors "leaks in the hull," and celebrates wins by threatening to make everyone walk the plank. Loud, loyal, and suspiciously good at pinching bugs. He's been through storms worse than your codebase.
