Built this because my prompts sucked
I’ve been using ChatGPT for coding, research, report writing, and pretty much everything lately.
One thing I’ve always struggled with is that I’m not very good at organizing my thoughts into words. Even when I know exactly what I want in my head, turning it into a clear prompt is surprisingly difficult sometimes.
After using AI heavily for a while, I realized a lot of bad responses were honestly caused by weak or vague prompts rather than the model itself.
So I ended up building a small Chrome extension called PromptLab for myself.
It analyzes prompts in real time and suggests improvements based on prompt engineering guidelines — things like adding missing context, clarifying goals, improving structure/output format, reducing vagueness, etc.
A simple example:
Before:
“analyze this stock”
After:
“Analyze NVIDIA stock from both technical and macroeconomic perspectives. Include growth drivers, risks, valuation concerns, and summarize the findings in a table.”
The goal wasn’t really to make “AI smarter,” but to make it easier to communicate with AI properly without constantly rewriting prompts over and over.
Still very early and I’m actively improving it, but I thought some people here might find it useful.
If anyone here has had the same frustration with vague prompts or inconsistent AI responses, I’d genuinely love your feedback/suggestions!
