Not another prompt library.

Libraries give you prompts someone else wrote. Umprompt generates prompts from your specific idea — structured around how your target tool actually works.

Built for people who actually use AI tools.

Not for sharing on Twitter. For shipping work. If you use Claude, Cursor, or ChatGPT to build real things, Umprompt is the missing step between your idea and execution.

Generate, score, optimize, and save.

One idea. Four steps. A quality-scored, optimized prompt saved to your workspace — ready to paste, iterate on, and reuse.

What it does

A workspace built around how AI tools actually work.

Generic prompt generators give you generic output. Umprompt is tuned per-tool, scored on real quality dimensions, and iterates until the prompt performs.

Tool-tuned generation

Cursor wants file paths and step-by-step instructions. Claude wants XML tags and explicit success criteria. ChatGPT wants persona and few-shot examples. Umprompt knows the difference — and structures the output accordingly.

Six-dimension score

Every prompt is rated on Clarity, Context, Constraints, Examples, Output Format, and Tool Fit — each 0 to 100. Each dimension comes with one concrete, actionable tip you can apply immediately.

One-click optimization

Click "Optimize weak dimensions" and Umprompt rewrites the prompt targeting every low-scoring area using the exact tips from your score. A before → after comparison confirms the improvement.

How it works

From idea to a prompt that actually performs.

1

Describe your goal

Type what you want to build, write, or generate in plain language. Add optional context — audience, constraints, output format — to sharpen the result.

2

Pick your tool

Choose Cursor, Claude, or ChatGPT. Umprompt knows what each tool responds to best and structures the prompt accordingly — XML tags for Claude, step-by-step for Cursor, persona-first for ChatGPT.

3

Generate & score

Get a full prompt in seconds, immediately scored across six dimensions: Clarity, Context, Constraints, Examples, Output Format, and Tool Fit. Each dimension includes an actionable tip.

4

Optimize & save

Click "Optimize weak dimensions" to automatically rewrite the prompt targeting every low-scoring area. Then save it to your workspace — reopen and iterate anytime.

Use cases

What people build with Umprompt.

Cursor93/100

Build a SaaS feature from a rough idea

Rough idea
Add a usage dashboard to my SaaS showing daily active users, revenue, and churn
What you get

A step-by-step prompt with file paths, component breakdown, stack constraints, and acceptance criteria — ready to paste into Cursor.

Scored, optimized, and saved
Why Umprompt

Cursor needs file-aware context and atomic tasks. Generic prompts produce incomplete code. Umprompt structures your idea into the format Cursor executes reliably.

Claude89/100

Research and strategy prompts

Rough idea
Analyze the top 5 competitors in the AI writing tools space — pricing, positioning, strengths, and gaps
What you get

A structured research prompt with role definition, analysis framework, output sections, and XML format tags — Claude follows it precisely.

Scored, optimized, and saved
Why Umprompt

Claude performs best with explicit reasoning structure. Umprompt adds role, scope, and output format that keep the model on track and prevent drift.

ChatGPT86/100

Sales, email, and workflow prompts

Rough idea
Write a 3-email cold outreach sequence targeting early-stage SaaS founders for a developer tools product
What you get

A persona-driven prompt with tone guidelines, example emails, and exact deliverables — a full sequence, not a vague instruction.

Scored, optimized, and saved
Why Umprompt

ChatGPT responds to strong personas and few-shot examples. Umprompt builds these automatically from your rough idea, adding the detail most users skip.
