Turnstone: Grok Bot alternative that runs on your AI, completely free
Turnstone launched on Product Hunt on November 6, 2026. Product Hunt's daily leaderboard lists it with a score of 254 and 29 comments, while the third-party tracker hunted.space reports 226 upvotes, 26 comments and second place for the day, so the exact vote count differs by source. The product is an app for Mac and iPhone that runs AI agents on accounts users already have. Users can connect ChatGPT, Claude, Gemini or Grok subscriptions, an OpenRouter key, or a self-hosted model such as Ollama running on the Mac.
According to the product's top comment on Product Hunt, when one subscription reaches its usage cap, agents move to another connected account and continue in the same conversation. The vendor's site adds that agents keep their job and memory when a user switches models mid-conversation. Routines can run on a schedule, and the iPhone app pairs with the Mac through a Phone remote setting. Work sent from the phone is handled while the agents keep running on the Mac. The iPhone app is distributed through TestFlight and the App Store and is free while in beta.
The Free tier covers persistent agents with memory and free connectors to apps, and it requires the user's own subscription or API key. A Cloud add-on at $49 per month keeps agents working around the clock, including when the Mac is off. The launch headline's claim of being completely free therefore applies to the Mac tier, not to hosted operation.
Why it matters
For founders, the pitch separates the agent layer from the model. The product's bet is that users will keep paying their existing AI vendors and bring their own keys, which lets the orchestration app itself be free. That makes bring-your-own-subscription access a credible economic model for competing agent products, and it puts pressure on cloud agent products that bundle model access into their own plans. A tool that moves work across providers also weakens model lock-in for buyers, which matters to any company whose product depends on one model vendor.
For investors, the structure is freemium: a free desktop tier with a $49 monthly cloud upsell. Launch votes are a weak proxy for retention, so the more useful signals are paid Cloud conversion and whether Mac users keep agents running over time. Operators should also check provider terms before relying on consumer subscriptions inside third-party agent software, since that access depends on rules the vendor does not control.
