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.
Hey Product Hunt! 👋 I'm Aryan, one of the founders of Turnstone.
I was using Grok Bot every day and kept hitting the usage limit right in the middle of real work. It was pretty frustrating because it felt like my team of employees would randomly take a 3 day vacation when I needed them the most. At the same time, I was already paying for Claude and ChatGPT, and those subscriptions were barely being used. This is why @jai_bhatia2 and I decided to build Turnstone.
Turnstone lets your Agents run on the AI you already pay for. You sign in with your Claude, ChatGPT, Cursor, or Grok subscription. You can also connect an API key (like OpenRouter), or point to a model you host yourself, like Ollama running on your Mac or a custom endpoint.
When one of your AI subscriptions hits its usage limit, your Agents move over to another one and keep working in the same conversation, so you're never stuck waiting for a limit to reset.
If you already have bots on Grok Bot, you can bring all of them over to Turnstone, and their skills and routines come with them. We made a bot that does the move for you: https://x.ai/bot/mrEaEhbIahB380oYB8N19
If you haven't tried Grok Bot yet but want to try something like it with the AI you already have, Turnstone is a great place to start. And if you don't pay for any AI yet, you can still get started with some free open source models we provide.
The gallery above shows the rest of what your Agents can do, from working in your apps to running Routines on their own every morning. You can send them work from your iPhone while they keep running on your Mac. Turnstone is completely free to use on your Mac, and it will stay that way.
Since it's Hypership Day 🚀, drop anything you wish Turnstone did in the comments and we'll try to ship as much of it as we can today. Our only goal is to free everyone's work from usage limits they can't control!
@jai_bhatia2 @aryanvij02 this looks great! If I install on my Mac what control / access will it have to device or should I use a Mac mini Hermes style
Ohhh so it just keeps things running smooth! How does it handle crashes between one model(where your credits have not expired) and how does it know when to go back to it?
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?
The bring-your-own-AI angle is what got me — pointing it at your own subscriptions or a self-hosted model and having it fail over when one hits a limit, instead of the run just dying, is the part I'd actually use day to day. Curious about the iPhone side: is it the full agent experience, or more of a companion for checking in on routines you set up on the Mac?
I woke up a few days ago to find that my grokbot usage was all the sudden at 100%. And then I started to find an alternative that could just hook to my claude sub.
Turnstone delivered! Platform works great, updates are happening daily, no complaints and really happy with the product so far. I've even got the mobile app which is working really well.
Installed a couple hours ago and really enjoying so far! I'm a solo founder with ADHD and having everything in one place, on my machine with any model I want is so nice. Also the cute little agents are a nice touch - excited to keep using and trying it out!
Oh, finally! I’m so tired of hitting the limit right when things get interesting!
Congratulations on the launch! This is a great way to maximize subscriptions!
What are some cool workflows that you've seen users create while using Turnstone?
If Claude dies mid-connector job and Ollama can't use the same tools, do you pause me or keep going blind?
Keeping the conversation when a provider hits its limit is useful. I'd want the switch to show which actions already finished, so the next model can continue without repeating them.
Super cool, are you guys planning on supporting local models or is that included already?
What is yall’s favorite agent template you recommend to anyone
