Super Agent Party gives you an AI companion with a face, a memory, and a to-do list, all running on your own server. The home screen starts a chat, summons a companion, creates a role or agent, queues a task, opens an AI browser, or adds an extension. Characters can appear as VRM 3D avatars, and character cards with long-term memory let several personas talk together in one group chat. The Task Center hands longer jobs to an agent that works in the background, calls tools through MCP and Agent Skills, and records every step in an execution timeline. A built-in browser lets agents open pages and act on them, and desktop vision tools can drive the mouse, keyboard, and terminal. One-click bot deployment connects an agent to Telegram, Discord, Slack, QQ, WeChat, Feishu, and DingTalk, and live-stream bots cover Bilibili, YouTube, and Twitch. The developer page serves an OpenAI-style endpoint, so other apps can call an agent as if it were a model. Extensions open in a sidebar or their own window. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Asking for a raise, declining extra hours, or setting a boundary with a friend can all be rehearsed first in SocialCoach, an AI coach built for the conversations people dread. Pick one of 63 scenarios across seven areas of life, or describe your own situation, and talk to a character who has real goals, doubts, and limits, so politeness alone does not win the argument. A stance meter shows how firmly the other person holds their position as you speak, and optional timed replies add pressure for readiness practice. The debrief quotes what you actually said before judging it, separates communication quality from the outcome, and suggests one thing to change on the next attempt. A Today page recommends a daily scene from your goals, Growth tracks practice history against five competencies, and a Learn library offers short videos, theories, and cases with sources. Step into 3D dinners, elevator lobbies, and offices to answer by typing or speaking. Practice history stays in the browser and can be exported, with no sign-up needed, and the mobile-first layout installs as an app on a phone. Settings accept your own Anthropic or OpenAI-compatible model, or a server key, so a self-hosted copy runs on any gateway. English and Simplified Chinese are both built in. Rehearse a hard conversation three times here and the real one feels smaller. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Project AIRI is the most popular open-source AI companion platform — a self-hosted recreation of Neuro-sama that brings AI-powered virtual characters into your world across web, desktop, and mobile. The system renders Live2D, Spine, and VRM 3D character models with auto-blink, eye tracking, and lip-sync driven by real-time voice synthesis, while the xsAI abstraction layer connects to 40+ LLM providers including OpenAI GPT-4, Anthropic Claude, Google Gemini, DeepSeek, and local models via Ollama and OpenRouter. Built from day one on WebGPU, WebAudio, Web Workers, WebAssembly, and WebSocket technologies, the browser version runs entirely client-side with PWA offline support while the server runtime enables persistent memory via PostgreSQL with pgvector embeddings and DuckDB WASM for client-side storage. The Minecraft agent plays autonomously using mineflayer with pathfinding, and a Factorio integration provides cooperative gameplay. Social integrations deploy your companion as a Discord bot joining voice channels, a Telegram bot, and a Twitter/X agent posting and replying autonomously. The desktop Stage Tamagotchi app provides an always-on-screen companion for Windows and macOS, while Stage Pocket brings the experience to mobile. Voice features include client-side speech recognition via VAD, multiple TTS providers including ElevenLabs, and screen vision capabilities. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Character-based chat and storywriting with large language models: TavernAI is the open-source frontend that leaves model choice to you. It generates no text itself; it connects to the backend of your choice - OpenAI (including GPT-4), Anthropic Claude, KoboldAI and KoboldCpp, Oobabooga's Text Generation Web UI, NovelAI, Ollama, and the crowdsourced Horde - so cost, model quality, and content policy are decided by your backend, not the interface. Characters are defined by portable card files in PNG or JSON format with personality, scenario, and example dialogue, and tens of thousands of community-made cards from sites like Chub.ai import directly. Conversations support group chats with multiple characters, a story mode for long-form writing, message swiping to branch between alternative responses, and full editing of any message. World Info injects lore into context when keywords trigger, keeping long roleplays consistent. Themes, custom backgrounds, and configurable generation settings round out the interface. It runs on Node.js, and the SillyTavern project began as a fork of it.
