Hello everyone!

I’m wrapping up my CS degree and recently spent a lot of time diving into "Vibe Coding" with Claude Code.

As a result, I built an automated prompt optimizer:

"My Personal Prompt Engineer"

The tool is built on a One-Click approach to maximize speed and eliminate manual iterations.

The goal is to strip away the overthinking:
You provide your raw intent in plain language, and the tool instantly transforms it into a professional, high-performance prompt
.

✅ 3 Modes (Fast, Pro, Master)
✅ Token-efficient logic
✅ 100% Privacy-first (Browser-based)
✅ Completely free

It started as a portfolio project, but I was surprised to see similar tools charging $5–$20/month for even more basic functionality.
After testing several paid options, I’m confident that the logic I’ve implemented produces better results.

I’ve kept it free because it was a "side hustle" to master the tech, but seeing the market demand makes me wonder if this is more than just a side project.

Would love your feedback!

I’m currently finishing my CS degree and recently spent some time practicing "Vibe Coding" with Claude Code to build out my portfolio.

I ended up creating an automated prompt optimizer.

Basically, you throw in a messy draft, and it spits out a structured, optimized prompt tailored for LLMs..

It started as a side project for my portfolio, but I was surprised to see quite a few tools in this space charging monthly subscriptions between $5 and $20 for similar functionality.

I’ve tested a few of them, and without trying to sound arrogant, I feel like the logic I built into my free tool actually produces better results.

I’m kept mine free since it was just a "side hustle" to learn the tech, but seeing people charge for this makes me wonder if I’m sitting on something actually valuable.

I'm curious - what do you think actually drives people to pay for these tools, and do you think a project like mine stands a chance at attracting real customers?

(I’m not sure if I can drop the link here without breaking the sub's self-promo rules.
Since the tool is completely free and I’m not making any money off it, I wasn't sure if that changed the rules.
If it’s okay to share it for feedback purposes, please let me know and I’ll edit the link into the post.)
