I built a small prompt manager that's now used by 100 people

I’d write a good prompt, use it once, and then spend forever trying to find it again. Notion, docs, screenshots, chat history — total mess.
So I built a simple tool for myself to save, search and reuse prompts. I called it EchoStash.
I shared it once on Reddit, and since then over 100 people started using it. I’ve been building it live based on their feedback.
Added so far:
+ official prompt libraries (like Anthropic's, OpenAI, Cursor etc.)
+ starter playbooks for people who don’t know where to start with prompts
+ better onboarding and UI
+ and working now on a community prompt library
