How do you store your (LLM) prompts?

I have a growing collection of prompts I reuse. Not the ones in my code. The ones I manually copy/paste into ChatGPT or Claude. Right now they're in Apple Notes and Notion. It works, but it's not great.

I'm curious how others handle this:

- Where do you store your prompt library?

- Do you use any specific tools or just plain text files?

- For those in companies: how do you share prompts with your team?

Would love to hear what's working for you.
