Turnstone is a Grok Bot alternative that runs on the AI you already have. Connect your own AI subscriptions, an API key, or your self-hosted model. When one hits its usage limit, your Agent switches to another and keeps going. Works on your Mac and iPhone. Completely free.

The part I care about is the handoff in the same conversation — does the raw working memory and the connector permissions come along, or does the next model just get a summary?
