An AI desktop companion who actually talks back. Speak to her out loud - she hears you, thinks, and answers in her own voice, lips moving in real time, in character. She remembers you, reacts to you, and runs entirely on your PC. No scripts. No subscription. She's yours.
Say something. Out loud. She's listening.
SYNTHS isn't a looping animation with a chat box. She's a real AI companion who hears your voice, thinks, and talks back in her own - lips moving in real time, in character, every word generated on the spot. She lives on your desktop, remembers you, and reacts to what you actually say and do. No scripts. No subscription. She runs entirely on your PC.
🎙️ Actually talk to her
Speak out loud - real voice, no typing. She hears you, understands, and answers in her own voice with real-time lip-sync, so her mouth moves to every word. It feels like talking to someone who's really there.
🧠 She remembers you
Persistent, on-device memory. Tell her your name, your day, what you're into - she holds onto it and picks up where you left off. Talk to her over weeks and the relationship actually builds.
💬 A personality, not a wind-up toy
Each companion has her own voice, mood, and opinions. She flirts, teases, pushes back, sulks, warms up. Nothing is canned - she's responding to you, right now.
👆 She knows you're there
Poke her and she feels where - and reacts the way she would. She's aware of you on the screen, not just playing an animation at you.
⚙️ How she actually works
You speak, she hears you on-device, her own AI writes a reply in character, she says it out loud in her voice, and her face lip-syncs in real time. Every step runs on your PC. No servers. No cloud. No waiting.
🔒 Yours, and private
No subscription, no monthly fee, no cloud. Buy once and she's yours forever - and your conversations never leave your machine.
