What is Turnstone
Turnstone is a free AI agent app for Mac and iPhone that runs on the AI services you already have. You can connect your existing AI subscriptions, an API key, or a self-hosted model, and the agent automatically switches to another connected provider when one hits its usage limit, so tasks keep running without interruption.
Key Features
Use Cases
- Use your existing AI subscriptions through a single agent app instead of switching tools
- Avoid workflow interruptions when a model reaches its usage limit
- Run AI agent tasks locally on a Mac or on the go with iPhone
Why do startups need this tool?
Startups that already pay for multiple AI subscriptions or run their own models can consolidate them into one free agent app and avoid downtime from usage limits, making better use of AI spend they already have without adding another subscription.
