See the difference

A small rewrite turns a vague prompt into a precise instruction.

Email

Before

write an apology email to a client

After

You are a customer success manager. Write a concise apology email to a B2B client whose shipment was delayed by 5 days. Professional but warm tone. Include a concrete next step.

Adds role, narrows the task, sets tone and output expectations.

Code Review

Before

review my react component

After

Review this React component for performance issues, accessibility gaps, and prop-type correctness. List each finding as a bullet with severity (critical/minor) and a suggested fix.

Specifies review criteria, defines output format, adds severity ranking.

Studying

Before

explain photosynthesis simply

After

Explain photosynthesis to a 14-year-old preparing for a biology exam. Use one clear analogy, then summarize light and dark reactions in two paragraphs. End with three quiz questions.

Defines audience, constrains format, adds a self-test output.

02·Practical use cases

Who uses this prompt improver and what they get.

Developer

Turn a vague coding ask into a spec

The prompt improver adds language, framework, edge cases, and output format (code only, tests, comments) so the model has less room to guess.

Marketer

Draft a brief for ads or landing copy

You get audience, tone, length, must-include points, and a clear deliverable — paste the improved prompt into ChatGPT, Claude, or Gemini.

Student

Structure a research or study prompt

Role, reading level, citation style, and success criteria are spelled out so the answer matches what your assignment actually needs.

03·How it works

How the prompt optimizer works on the web.

01Paste

Paste a rough prompt — one line or a messy paragraph — into the box at the top. The prompt improver works on instructions for any general-purpose LLM.

02Improve

Run Improve. You receive a clearer prompt with structure, constraints, examples, and output format. If your prompt is already strong, you get an already-good result with no wasted rewrite.

03Copy

Copy the improved prompt into your chat tool, or open @vustPromptBot in Telegram for on-the-go edits and the shared VUST wallet.

05·Quality & trust

What to expect from this tool.

Already good

When your prompt already has role, task, constraints, and output format, the tool tells you — and does not consume quota on a pointless rewrite.

Model

Instruction improvements on the web run through Claude Sonnet. The goal is clearer tasks for the model you paste into — not answering the task for you.

Free quota

Ten prompt improvements per 4 hours on this page. Telegram PromptBot uses the same crystal wallet if you want mobile access or saved runs.
