llt22/talkio

Local-first multi-AI group chat desktop app — pull gpt, Claude, Gemini, DeepSeek into one conversation. Tauri 2 + React 19.

What it solves

Talkio is a multi-model chat client that allows users to bring multiple AI models into a single group chat. This solves the limitation of traditional one-on-one AI interactions by enabling models to discuss, debate, or collaborate on a single topic, each acting as a distinct persona with its own system prompt and parameters.

How it works

Built with Tauri 2 and React 19, the application operates on a local-first architecture. It connects to various AI providers (such as OpenAI, Anthropic, DeepSeek, and Groq) via API keys. It utilizes the Model Context Protocol (MCP) to connect to external tool servers for system capabilities like calendars and reminders. All user data and API keys are stored locally using SQLite and system credential stores (like macOS Keychain) to ensure privacy.

Who it’s for

It is designed for users who want to experiment with different AI perspectives, create complex AI-driven workflows (like code review or translation teams), or manage multiple AI models across desktop and mobile platforms in a single interface.

Highlights

  • Multi-AI Group Chats: Support for @mentioning specific models or letting all models take turns speaking.
  • Persona System: Customizable system prompts, temperature, and reasoning effort for each AI role.
  • MCP Tool Integration: Support for both SSE and Stdio transport modes to call external tools.
  • Local-First Privacy: No cloud services; data is stored in SQLite and API keys are stored in system credential managers.
  • Advanced Rendering: Real-time streaming output with support for Markdown, Mermaid diagrams, KaTeX, and HTML/Three.js previews.
  • Linguistic & File Support: Integrated Whisper-compatible STT for voice input and support for parsing PDF, Word, and Excel files.
