I built Apple Reminders…inside ChatGPT. This is real, and it's a native ChatGPT Extension you can try right now. Free and open source. Version 2.0 of my Reminders CLI, RemCTL, is out now with complete support for MCP and the brand new @OpenAIDevs MCP Extensions. With RemCTL 2.0, you have a power-user interface for Reminders inside ChatGPT for Mac. You can use keyboard shortcuts, there's a ⌘K palette, and view tasks as lists, Kanban, or Calendar. It's basically "Reminders Pro". But most importantly, you can work with ChatGPT in this Reminders UI and ask it to do whatever you want. Attach any task to a conversation, or select multiple ones and pass them to ChatGPT. I was inspired by @danshipper's concept of "Codex apps", and when I saw @mxstbr's announcement yesterday, I knew what to do. This feels like a brand new way of getting work done, and I'm excited to build more. Have fun! https://github.com/viticci/remctl
