Stop hand-tuning prompts. Auto-apply 12 techniques in 30s
3 followers
You know how to write good prompts. But manually applying CoT, few-shot, role assignment to every prompt is slow. PromptUp auto-applies 12+ techniques in 30 seconds — paste, diagnose, pick from 3 rewrites. Free, no account needed.
I spent 20 minutes yesterday adding CoT, role assignment, and output constraints to a single prompt. The result was better. But 10 minutes for one prompt is a terrible workflow.
That's the moment that made me build PromptUp.
The actual problem
If you're reading this on Product Hunt, you probably already know that good prompts need structure. You know about Chain-of-Thought, few-shot examples, role assignment. You've read the papers, you've seen the benchmarks.
But knowing the techniques and applying them consistently to every prompt you write are two different things. Most of us default to bare prompts because the mental overhead of manually structuring each one isn't worth it — unless the task is high-stakes enough to justify the effort.
That gap between what we know and what we actually do is the problem PromptUp solves.
What it does
Paste any prompt. In 30 seconds:
1. 4-dimension score (Clarity, Executability, Quality Prediction, Reusability) — not a vague grade. A breakdown that shows you exactly where the prompt is weak and why.
2. 3 rewritten versions, each using a different technique combination — CoT + role assignment, delimiter structure + few-shot, or a combined approach. Each option shows which techniques were applied. You pick the one that fits your use case.
The engine runs 12+ techniques — CoT, few-shot, role assignment, negative prompting, Tree of Thoughts, delimiter structure, output constraints, audience specification, emotional prompting, chain of verification, self-consistency, prompt repetition — and selects the right combination based on the diagnosis.
It's the prompt engineering workflow you'd do yourself, automated down to 30 seconds.
A real example
Before: "Write marketing copy" → 18/100
After (Role Assignment + Output Constraints + Audience Specification):
"You are a senior direct-response copywriter. Write Instagram ad copy for a summer linen dress targeting women 20-30s. Include product details, 3 creative versions (emotional hook, feature-focused, punchy headline), relevant hashtags, and a shop-now CTA. Each version under 50 words for mobile readability." → 91/100
You could do this yourself. PromptUp just does it in 30 seconds instead of 10 minutes.

Drop a prompt in the comments — the messier the better. I'll run it through PromptUp and post the before/after with the technique breakdown. Curious to see how it handles prompts from this crowd.
