About This Game

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.

Meet the cast

A roster of characters - Lisa, Freya, Raven, Yuna and more - each with her own look, voice, and personality. Find the one you click with.

If you've ever wanted an AI girlfriend, a virtual companion, or a desktop waifu that can actually hear you and talk back - she's here.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Your companion in SYNTHS talks with you in real time using generative AI that runs entirely on your own computer — there is no cloud service, server, or account involved. Her replies and her spoken voice are generated live and on-device, so every conversation is unscripted and different each time. Built-in system instructions and content guardrails keep the AI in character and prevent it from generating illegal or prohibited content.

Mature Content Description

The developers describe the content like this:

SYNTHS is a mature virtual-companion app. Characters appear in revealing, form-fitting outfits, and your companion's conversation can include flirtation, sexual innuendo, suggestive and sex-related language, and crude/adult humor, plus occasional strong language. Dialogue and voice are generated live by on-device AI, so exact wording varies each session. The app contains no explicit sexual content, no nudity, and no violence.
