About OneStone AI

What is OneStone AI?

OneStone AI is a free, local-first AI agent desktop platform for Linux and Windows. It gives you a personal AI agent that runs on your own machine — no account, no subscription, and your data stays on your computer. When you want it in a browser or on your phone, there's an optional web dashboard at app.onestoneai.com.

The agent connects to 7 AI providers (Anthropic, OpenAI, Google Gemini, Groq, Mistral, OpenRouter, Ollama, including local models via Ollama), runs scheduled routines automatically, maintains persistent memory across sessions, handles email through AgentMail, and exposes 118+ tools via the Model Context Protocol (MCP).

Unlike cloud-hosted AI assistants, the desktop app stores all conversations, memory, contacts, and files on your local machine. You own your data — always.

Why Local-First?

Cloud AI platforms require you to trust a third party with your conversations, files, and workflow data. OneStone takes a different approach: the application runs as a desktop app on your machine, and your data directory lives on your local filesystem. AI providers process your prompts (as they must), but your memory, knowledge base, routines, and operational data never leave your control.

This isn't just a privacy choice — it's an architecture choice. Local-first means the agent works offline (with local models), starts instantly, and never depends on a third-party service for its core functionality.

Key Capabilities

• Multi-provider chat — Anthropic, OpenAI, Google Gemini, Groq, Mistral, OpenRouter, Ollama. Pick the model per channel: chat, routines and summarization can each use a different one.
• Scheduled routines — cron-driven agent jobs that run on their own: research, monitoring, auditing, reporting.
• Persistent memory — rules, knowledge, and project-scoped context that carry across sessions.
• 118+ MCP tools — files, browser, email, calendar, code analysis, web search and more, plus any external MCP server.
• Email via AgentMail — thread-based email with custom domains; the agent can send, read and reply.
• Phone access — reach your agent from your phone through the relay.

About the Creator

OneStone AI is built by Joey Mantione, a developer focused on AI agent systems, desktop applications, and local-first architecture. Joey builds and operates OneStone as a solo developer — designing the architecture, writing the code, managing releases, and using the system daily as his own primary development tool.
