Prompt Formatter

A deterministic formatting tool — not an AI evaluator. It cleans up whitespace and, optionally, wraps labeled lines into tags.

How to use it

  1. Paste your draft prompt.
  2. Turn on whitespace cleanup, section wrapping, or both.
  3. Copy the formatted result.

Limitations

Section wrapping only recognizes short "Label:" style lines at the start of a line — it won't restructure prose that doesn't already follow that pattern, and it won't touch the meaning or wording of your content.

Frequently asked questions

Does this use AI to improve my prompt?
No. This is a plain text-formatting tool — it trims whitespace and can wrap labeled lines into tags using fixed rules, not a language model evaluating or rewriting your wording.
What does "wrap labeled sections" actually do?
If a line starts with a short label like "Context:" or "Task:", that line and the text following it get wrapped in a matching tag, like <context>...</context>. Many people find tagged sections easier for both themselves and an AI model to parse.
How accurate is the token estimate?
It's a rough approximation (roughly 4 characters per token for English text), not the exact count a specific model's tokenizer would produce. Treat it as a ballpark, not a precise number.
Is my prompt sent anywhere?
No — formatting happens entirely in your browser.
