Show HN: PromptKelp – A prompt manager I'm using to build itself

https://promptkelp.com
1•nathan-aii•1mo ago
Hey HN,

I just launched the V1 landing page for my new project, PromptKelp.

It’s a tool designed to help manage, version, and organize prompts as AI projects scale up.

The motivation was simple: I was working on larger generative AI projects and found myself drowning in text files, snippets, and endless copy-pasting trying to keep track of which prompt version did what.

The fun part of this build is that about halfway through, I realized I needed the tool to finish the tool. I’m now fully dogfooding PromptKelp to manage the various system prompts and generation tasks used within PromptKelp itself (as well as my other larger projects).

I’m looking for a brutal roast of the landing page.

My goal for this week is to land my first paying customer ($10/mo), so I need to know if the current page communicates the value clearly.

Is the headline confusing?

Is it obvious within 5 seconds what the tool does?

Would you trust this stack for a production project?

(For those curious, the app was built using Lovable, which has been an interesting experience for rapid development.)

Thanks for the feedback.

Can graph neural networks for biology realistically run on edge devices?
