Natural conversation

Talk to your character by text or voice.

Call her name to enter continuous voice mode.

She remembers your past conversations, even the next day.

Talk out loud — she listens.

Local Whisper speech recognition — fully offline.

・Call her name to enter continuous voice mode (hands-free)

・Or push-to-talk with a hotkey

・Works with USB mic, Bluetooth headset, or built-in mic

・Recognized speech goes straight to the AI and comes back as her voice

Not required — you can use text input only if you prefer typing.

7-stage intimacy system

A character who is polite and distant at first opens up to you over time — and eventually starts to spoil.

Just met → Acquaintance → Friends → Close friends → Best friends → Special person → Soulmate

Intimacy changes naturally through conversation and touch.

Her core personality (tone / character) stays intact throughout.

Her face moves in sync with her words — not scripted.

The AI picks facial morphs and body motion for each response, live, based on the meaning of what she says.

She blushes when embarrassed, smirks when teasing, pouts when annoyed — automatically, no scripts, no preset triggers.

VMD motion playback with a built-in CCD-IK solver.

Same motions work on both VRM and MMD models.

Import your own VMD motions freely.

Touch interaction

Pet her head, poke, or grab — reactions vary by body part and intimacy level.

The more you touch her, the closer she gets.

Bring your own model

Download personal-use VRM / MMD models from Niconi Solid, BOOTH, VRoid Hub etc. and import directly.

Models created in VRoid Studio work out of the box.

Or write your own system prompt to create any character you want — she'll take on that voice from the next reply.

Save multiple named presets and swap on the fly (chat mode ↔ Q&A mode etc.).

Swap outfits with one click from ZIP-packed model sets.

Pin her to your desktop with click-through mode — she stays present without blocking your work.

Local AI keeps getting better — for free

Local LLMs evolve fast.

Google Gemma 4 (released April 2026) changed the game for local AI.

Gemma 4 26B-A4B (MoE) has 26B parameters but only 4B active per token — so you get 26B-level quality at 7B-level speed, on as little as 12 GB of RAM.

Gemma 4 is particularly strong at character conversation and roleplay, producing expressive, natural responses.

Buy this app once and every future model works with it, at no extra cost.

Your hardware stays the same — the AI just keeps getting smarter.

System requirements — lighter than you think

This app uses local LLMs, so available models depend on your PC. The initial setup auto-detects your RAM and suggests the best model.

━━━ macOS (Apple Silicon) ━━━

Apple Silicon shares RAM with VRAM, so RAM size is what matters.

・8 GB RAM+ : Qwen 3.5 4B (minimum)

・16 GB RAM+ : Gemma 4 26B-A4B ★recommended

・24 GB RAM+ : Gemma 4 26B-A4B ★best (comfortable)

Response latency (first token / full response):

・M1 8 GB + Qwen 4B : ~1s / ~3s

・M2/M3 16 GB + Gemma 4 26B : ~1s / ~3s

・M4 24 GB+ + Gemma 4 26B : <1s / ~2s

━━━ Windows (NVIDIA GPU) ━━━

On Windows, VRAM (GPU) matters more than system RAM.

・6 GB VRAM (RTX 3060 etc.) : Gemma 4 12B-E4B / Qwen 3.5 4B

・8 GB VRAM (RTX 4060 etc.) : Gemma 4 26B-A4B ★recommended (with GPU Offload)

・12 GB VRAM (RTX 4070 etc.) : Gemma 4 26B-A4B ★best

・16 GB+ VRAM (RTX 4080 etc.) : Gemma 4 26B-A4B (plenty of headroom)

※ LM Studio auto-tunes GPU offload and context length

━━━ Windows (no GPU / CPU inference) ━━━

・8 GB RAM+ : Qwen 3.5 4B (works but slow)

・16 GB RAM+ : Gemma 4 12B-E4B (slow but functional)

━━━ Notes ━━━

※ Kawaii Agent is optimized for roleplay and character conversation, so we recommend Gemma 4 across all environments. Its expressiveness and naturalness are on a different level.
