Memoh is an open-source, full-stack AI agent platform that provides each agent with an isolated cloud computer (filesystem, desktop, browser, network, long-term memory). The system is built around a Go backend with Echo HTTP and gRPC, Vue 3 frontend with Pinia, and an Electron desktop shell. It supports multiple agent runtimes (native, ACP, Codex, Claude Code), a wide range of messaging channels (Telegram, Discord, Feishu, WeChat, LINE, DingTalk, etc.), and container-based workspaces via containerd or Docker. The architecture is a monolith with clearly separated packages for channel adapters, context management, session orchestration, and tool execution. The codebase demonstrates high engineering craftsmanship with extensive test coverage, sophisticated concurrency patterns (runtime fences, decision waiters, atomic compaction barriers), and a modular context fragment system for prompt assembly. It is actively maintained with frequent commits, thorough CI/CD, and over 140 database migrations.
Project AIRI is a comprehensive multi-platform AI agent and virtual character platform. It functions as a desktop application (Electron), web interface (Vue.js), and mobile client (Capacitor), centered around an LLM-powered 'brain' that controls 3D avatars (Live2D, VRM, Spine) and interacts with the physical world via computer automation (MCP) and gaming bots (Minecraft). The system integrates speech-to-text, text-to-speech, and vision processing to create a conversational agent capable of real-time interaction. It features a robust backend server (Hono/PostgreSQL) for authentication, billing (Flux currency), and provider routing, alongside a plugin system allowing third-party extensions to inject functionality. Architecturally, it is a large monorepo managed by pnpm and Turbo, separating concerns into apps, packages, services, and plugins. The codebase demonstrates significant engineering effort in managing complex state across Electron IPC, WebSocket communication, and local-first data synchronization. It implements custom concurrency ledgers for billing, GPU resource coordination for model inference, and sandboxed execution environments for AI planning tasks. The system is actively developed with frequent commits and a large plugin ecosystem, though it relies heavily on bleeding-edge dependencies and beta libraries. The platform solves the problem of creating autonomous virtual characters with agency, moving beyond simple chatbots to agents that can control computers, play games, and maintain persistent memory. It exposes a standardized provider registry for AI models and a plugin SDK for extensibility. While the architecture is sophisticated, the reliance on rapidly evolving AI standards (MCP, LLM APIs) and bleeding-edge Node.js versions introduces technical debt and maintenance overhead.
This repository is a mobile SDK for real-time interactive AI avatars, primarily targeting Android and iOS platforms. It provides on-device inference for speech recognition (via WeNet) and face/body segmentation (via ncnn-based U-Net models), enabling low-latency lip-sync and avatar animation driven by audio input. The SDK is structured as a C++ core with platform-specific wrappers (Java for Android, Objective-C for iOS), and includes bundled third-party libraries (ncnn, OpenCV, FFmpeg, ONNX Runtime) for computer vision, audio processing, and neural network inference. In production, the system ingests 16kHz PCM audio from a microphone, extracts MFCC features, runs streaming speech recognition, and simultaneously processes the audio through a U-Net model to generate facial animation frames. These frames are rendered using OpenGL ES (Android) or Metal (iOS) with alpha blending for compositing onto a background. The SDK also includes model download, encryption (AES-128-CBC), and resource management utilities. The architecture is monolithic: all core logic lives in a single C++ module (duix-sdk), with platform-specific integration code in the app directories. The demo app in Android provides a fully functional test harness. While the SDK is feature-complete and demonstrates significant engineering effort in mobile AI inference, the codebase exhibits several quality issues: duplicated third-party headers across architectures, hardcoded encryption keys, outdated library versions (OpenCV 4.6.0, ncnn 2022/2023), and minimal inline documentation. The high star count and fork activity suggest a strong community, but the code itself is functional rather than exemplar. The most reusable components are the reference-counted memory allocator (dh_mem.h) and the AES stream decryption wrapper (gaes_stream.h), which can be extracted for general-purpose use.
