Show HN: I made an AI prompt manager to stop rewriting the same prompts

[debeast]

I made EchoStash.

If you’ve ever written a great prompt, used it once, and then couldn’t find it again — I’ve been there too.

I kept losing my best prompts in chats, notes, or random documents. Every time I started a new project, I ended up rewriting the same stuff or wasting time trying to remember where I saved things.

So I built EchoStash — a simple tool for developers who use AI tools regularly.

It helps you save, organize, and reuse your prompts. You can tag them by project or tool, and when you need something, just search.

The cool part? EchoStash has AI-powered search. You don’t need to remember the exact words — just type what you’re looking for, and it’ll find the right prompt.

It’s fast, minimal, and built to save you time without getting in the way.

Would love feedback from devs working with LLMs or building AI workflows. --> https://www.echostash.app

AI powered search? So i type my intent and get my “best” prompt back?

[debeast]

Yep, that’s the idea. You just type what you’re trying to do — like “debugging prompt for React errors” or “explain code to a junior dev” — and it finds the best one you’ve saved for that use case.

Super handy if you’re jumping between projects or tools and don’t want to reinvent prompts every time.

Out of curiosity — how are you currently managing your own prompts?

[messi-ai]

Just saving them on side notes.. so are you also injecting parameters for templates?

[debeast]

Nice — that’s what I used to do too (Notion, Apple Notes, random files everywhere).

And yeah, you can create templates with parameters — for example, something like:

Write a {tone} product description for a {product_type} targeting {audience}

Then when you reuse it, you just fill in the values. Makes it super easy to adapt prompts without rewriting the whole thing.

Would love to know how you would use that — have any prompt templates you always reuse?

[debeast]

Totally get that — I felt the same with most prompt libraries. That’s why I built EchoStash to be more like a “prompt memory” — quick search, AI retrieval, and no clutter.

[messi-ai]

I have many obviously, i rather not say. I just found prompt libraries to be inefficient for me. It’s just another place that I’m loosing my prompts in.

[mano_vint]

is this like for a specific tool? or just a generic library?

[debeast]

Good question — it’s a generic prompt library, not tied to any one tool.

So whether you’re using GPT-4, Claude, Perplexity, or anything else, you can stash and reuse prompts across all of them. It’s meant to be your “prompt brain” — separate from the tools themselves.

Curious — what models or tools do you mostly use prompts with?

[mano_vint]

Interesting.. Cursor github perplexity mainly
