This plugin is inspired by goblin.tools's Magic ToDo.

Click on a task in Obsidian, press Ctrl + M (or Command + M on a Mac) to ask ChatGPT to break down the task into smaller sub-tasks. You can change the shortcut to something else if you prefer.

On mobile, tap on the task you want to break down and pull down to open the menu of actions. Search for Magic Tasks and you get it from there.

Download the latest release and copy the main.js and manifest.json files to a new folder called magic-tasks in VaultFolder/.obsidian/plugins/. Enable it from Community plugins.

Alternatively, you can install it by just copying the link into BRAT.

You will need an OpenAI API key for this work. This also means your task will be sent to the OpenAI servers for processing. Read their privacy policy to see how they handle your data.

There's also a cost associated, although I can't say how much each query will cost. Under $0.01, from my experience.
