AIvy is a next-gen desktop mascot — a 3D character that talks to you naturally, powered by AI. Load your favorite VRM model, and watch it watch over your work, chime in softly, and feel like it's really there. A new desktop life, with a companion all your own.

<h2 class="bb_tag" >What is AIvy?</h2><p class="bb_paragraph" >AIvy is a next-generation desktop mascot that brings a 3D character to your PC desktop—one you can actually talk to, powered by AI. Load your favorite VRM model and watch it come to life in the corner of your screen, chatting naturally like a companion who's really there. The name comes from &quot;AI + ivy&quot;—the gentle vine that quietly winds itself around your everyday life.</p><h2 class="bb_tag" >Build Your Own Companion, Your Way</h2><p class="bb_paragraph" >The heart of AIvy is the freedom to combine the look, the mind, the voice, and the personality—piece by piece—to craft a companion that's truly yours. Load any VRM model from VRoid Studio, VRoid Hub, or your own creations to bring your favorite character to your desktop.</p><p class="bb_paragraph" >For the mind, AIvy is a local LLM runner built on llama.cpp. On first launch you pick from a dropdown an open-source language model that fits your language and download it once. From then on it runs <strong>fully offline</strong>, with no account, no API key, and no internet connection required. Your conversations are never sent anywhere. You can grab additional models (lighter or higher-quality) from inside the app any time and switch between them to match your PC and your use case.</p><p class="bb_paragraph" >In short, AIvy is the same kind of local LLM client as LM Studio, Jan, or GPT4All—just dressed up in a VRM character UI instead of a chat panel. The first-run download catalog is restricted to permissive licenses (Apache 2.0 / MIT) so the models are safe to use in commercial and streaming contexts.</p><p class="bb_paragraph" >The voice is delivered by your OS's built-in TTS. If you have a local TTS engine (such as VOICEVOX) set up separately, you can optionally connect it to AIvy for a more characterful voice. Personality and speech style can be set from ready-made presets, or written freely in your own words to shape every nuance. With support for 11 languages including Japanese, English, Chinese, and Korean, people around the world can spend time with their own one-of-a-kind companion in their own language.</p><h2 class="bb_tag" >A Quiet Presence, Designed Not to Get in the Way</h2><p class="bb_paragraph" >AIvy isn't built to be the assistant that keeps interrupting you—it's built to be the companion whose presence you simply feel. When you're focused, it watches over you in silence. In a quieter moment, it might softly check in with &quot;Maybe time for a break?&quot; or &quot;Done with that video?&quot;—a single line that fits the situation. And whenever you feel like talking, it's always there to answer. The mascot stays on top of every window but lets your clicks pass right through, so it never blocks your work. Every detail is tuned so it stays comfortable to have around, even on the longest workdays.</p><p class="bb_paragraph" >With these gentle gestures and the right kind of distance, AIvy adds a quiet color to your desktop life. Work, breaks, time alone—every part of your day gets a little warmer with AIvy by your side.</p><h2 class="bb_tag" >What AIvy Can Do as Your Companion</h2><p class="bb_paragraph" >AIvy isn't just a mascot that sits quietly in the corner of your screen. It softly senses what's going on with your PC, and is gradually gaining features that let it be there for you like a real companion.</p><ul class="bb_ul"><li><strong>Proactive talk</strong> — Even when you don't say a word, it speaks up on its own at just the right moment. After a stretch of silence or when you wrap up a task, it gently adds a line that fits the moment.</li><li><strong>Reads the room and stays quiet</strong> — It automatically senses when you're on a call, in an online meeting, gaming, watching a video, or streaming, and holds back from speaking up during those times. When you need to focus or don't want your audio interrupted, it quietly keeps watch instead.</li><li><strong>Active-app awareness</strong> — It recognizes the app you currently have open (a game, browser, editor, and so on) and brings up topics that fit what you're doing right now, like &quot;Really in the zone, huh?&quot; or &quot;That game again?&quot;</li><li><strong>Long-term memory</strong> — It remembers the conversations you've had and your tastes and habits, and gently works them into what it says next time. The more you use it, the more it grows into a companion that truly knows you.</li><li><strong>Alarms</strong> — When the time you set arrives, the character lets you know out loud. Instead of a cold notification beep, your companion tells you the time in its own voice.</li><li><strong>CPU usage monitoring</strong> — It keeps a casual eye on how hard your PC is working, and if the load stays high for a while, it checks in with something like &quot;Looks like your PC's pushing itself a bit?&quot;, looking out for both you and your machine.</li><li><strong>Calendar integration</strong> — It keeps track of your schedule, reminding you when an event is coming up and casually mentioning what's on your plate that day.</li></ul><h2 class="bb_tag" >No Servers. It All Stays on Your PC</h2><p class="bb_paragraph" >AIvy is a fully standalone app that runs entirely on your PC alone. Everything — from generating its replies (local LLM) to synthesizing its voice — is processed right on your machine, with no AIvy servers in between. Because of that —</p><ul class="bb_ul"><li>Your conversations are never sent anywhere, so your privacy is protected.</li><li>No account needed, and after the first model download you don't even need an internet connection.</li><li>No running costs — no monthly fees, no pay-per-use. Once it's yours, it stays with you at no extra charge.</li></ul><h2 class="bb_tag" >Supported Engines</h2><p class="bb_paragraph" ><strong>LLM (the mind)</strong></p><ul class="bb_ul"><li>Local inference (default) — first-run dropdown picks an open-source model that fits your language</li><li>llama.cpp-based local inference — conversations stay on your PC</li><li>Additional models can be downloaded from the in-app settings any time</li></ul><p class="bb_paragraph" ><strong>TTS (the voice)</strong></p><ul class="bb_ul"><li>OS Built-in TTS (Windows SAPI / macOS Speech)</li><li>Optional local TTS integrations (VOICEVOX / AivisSpeech / Piper TTS) — if the user has installed them separately</li></ul><h2 class="bb_tag" >Important Notes</h2><ul class="bb_ul"><li>Currently in beta. Features, behavior, and improvements will continue to evolve</li><li>Please use VRM models you have proper rights to</li></ul><h2 class="bb_tag" >Streaming, Videos &amp; Let's Plays</h2><p class="bb_paragraph" >You are free to stream, record, and share content created with AIvy. When you do, please follow the license terms of the VRM model, the TTS engine (VOICEVOX, AivisSpeech, etc.), and the language model (Sarashina, Qwen, Phi-4, etc.) you actually use. Whether commercial use, monetization, and on-screen credits are required depends on each VRM, engine, and model's own license — not on AIvy.</p>
