Turnstone (myturnstone.ai) is a YC-backed Mac app for personal AI agent teams that is model-agnostic by design: agents run on the ChatGPT, Claude, Grok, or Cursor subscriptions you already pay for—or OpenRouter keys and local models—and automatically fail over when one hits its rate limit. It reached #2 on Product Hunt on November 6, 2026 with roughly 1,624 upvotes per the launch listing.
