Mesh Avatar Studio

Charakuru is a local character-modeling kit that turns a single full-body illustration into a VRM avatar with assistance from an AI agent. It generates eight reference images, creates and processes 3D candidates through Tripo, and uses Blender for part separation, weight transfer, rigging, spring physics, and VRM export. The workflow pauses at checkpoints so the user reviews images, selects candidates, adjusts proportions, and checks motion while the agent handles file management and browser or Blender operations. The kit includes a local review app, seven agent Skills, scripts, documentation, and a base Blender body for weight transfer. It runs on a user's computer and uses external services through the user's own accounts, including Tripo, an agent with image-generation and browser-control capabilities, Blender, the VRM Add-on for Blender, and Blender MCP. The project is distributed through release ZIP files rather than GitHub's automatic source archive and is still in development. Current limitations include neutral faces with fixed gaze, no expressions or eye movement, and physics checks that occur in the exported VRM rather than the in-app walk preview. Its terms permit private, commercial, and non-commercial use subject to redistribution restrictions and additional licensing requirements for businesses meeting the stated revenue or funding threshold.

MascotAI is a web application that generates animated SVG mascots for web and mobile applications. It offers customizable gestures and themes, and produces download-ready mascot asset packs for direct integration into products.

Project AIRI is a self-hosted AI companion for creating virtual characters or digital pets, with Live2D or VRM avatars and real-time voice chat. It connects to multiple model providers and can interact through Discord, Telegram, and games including Minecraft and Factorio. The project supports web, macOS, and Windows, and provides installation options through Winget, Scoop, and Homebrew Cask.

Sprite Studio is a local-first, open-source desktop AI workbench for creating, animating, testing, organizing, and exporting 2D game art. It combines prompt- and reference-based generation with pixel-scale review, sprite viewing, animation planning, loop testing, rigging, deterministic rendering, and PNG sprite-sheet export with metadata. For animation, the AI plans a complete motion sequence and generates frames sequentially using the source asset's identity and neighboring accepted frames. Its native Rust rig engine uses named joint, anchor, contact, and pivot points plus capsule bones; it assigns opaque pixels to bones, supports planted contacts through analytic two-bone inverse kinematics, and renders frames through bone transforms and nearest-neighbor inverse mapping without image generation. The resulting frames flow into asset organization, quality analysis, the playground, and exports. The application runs on macOS, Windows, and Linux and is built with Tauri, Svelte, Rust, SQLite, and an installed Codex CLI. It is designed for local-first use and does not target Android or iOS.

Persona is an open-source, cross-platform desktop character that gives voice conversations an animated visual identity. It listens locally to a selected application's playback process rather than the microphone, using PipeWire playback-stream capture on Linux, WASAPI process-loopback capture on Windows, and a Core Audio process tap on macOS. Imported VRM character models switch between idle and speaking animations, with support for custom VRMA actions, model libraries, click-through desktop-pet behavior, and a local MCP server. Persona does not save audio, produce speech, transcribe content, or send audio over the network. It is distributed as an AppImage or DEB on Linux, an NSIS installer on Windows, and DMG or ZIP packages on macOS.
