What is Turnstone?
Grok Bot alternative that runs on your AI, completely free
Turnstone is a model-agnostic Grok Bot alternative that runs on the AI you already have. Connect your own AI subscriptions, an API key, or a self-hosted model, and when one hits its usage limit your agent switches to another and keeps going. Mention it on X to get answers, or use it in Telegram, WhatsApp, Slack, Discord, email and web chat — it works on your Mac and iPhone, completely free.
- Uses your own subscriptions, API keys or self-hosted models
- Answers on X, including image and video questions
- Agents with memory that search, research and run tasks
- Mac app runs locally; conversations can be deleted
- Connects X, Telegram, WhatsApp, Slack, Discord, Notion, Calendar and more
The Mac app is free forever. The Cloud add-on, for keeping agents working while your Mac is off, is $49 per month and coming soon, with the first month free for the first 1,000 users.
