Turnstone

Turnstone is a Mac app that provides persistent AI agents with memory, running on your existing AI subscriptions like ChatGPT, Claude, Gemini, or Grok. It allows users to create a team of AI agents, each with specific jobs, that learn how you work and remember past interactions. Your data and memory are stored locally on your Mac, ensuring privacy and control.

Turnstone is a Mac application designed to provide persistent AI agents with memory, operating on the AI subscriptions you already possess, such as ChatGPT, Claude, Gemini, Grok, or OpenRouter. This platform allows users to create a team of AI agents, each assigned a specific role, that learn individual work preferences and retain conversational history. The core principle is to make working with AI feel intuitive and seamless, akin to collaborating with a highly competent friend.

The application emphasizes data privacy and user control, storing all agent memory and data locally on your Mac in an accessible folder. Turnstone does not retain copies of your data or use it for model training. Users connect their existing AI subscriptions or API keys, eliminating the need for additional AI purchases. Agents can be switched between different models mid-conversation while retaining their job context and memory.

Key capabilities include the ability to assign a "Chief of Staff" agent to manage tasks and delegate to other specialized agents. Each agent remembers how you prefer work to be done and can be assigned to the AI model best suited for its task. Turnstone agents can keep schedules, providing regular updates or performing routine tasks when your Mac is on. They learn your writing style across various applications like Gmail and WhatsApp, drafting communications in your voice, with nothing sent without your approval.

Turnstone integrates with over 60 apps, including Gmail, Calendar, Slack, Notion, and Drive, allowing agents to work within your existing ecosystem. Agents can also use their own browser tabs to navigate websites, read content, and fill out forms. The platform supports working with files and documents, enabling agents to read PDFs, analyze spreadsheets, and draft reports. Users can save repeatable processes as "Skills" for future use.

While the core Turnstone Mac app is free, a "Turnstone Cloud" service is planned to allow agents to continue working even when your Mac is closed, and to enable mobile access via an iPhone app and web app. This cloud service will be a paid subscription. Turnstone is built for both Apple silicon and Intel Macs, offering a flexible and private way to integrate AI into your daily workflow.
