What is the AI Prompt Sanitizer?

The AI Prompt Sanitizer is a tool built specifically for heavy ChatGPT and Claude users. When you copy text from PDFs, websites, or code editors, you often copy invisible "garbage" like zero-width spaces, excessive markdown, smart quotes, and HTML tags. These hidden characters waste your valuable AI token limits and can confuse the model. This tool strips all formatting, normalizes text, and compresses whitespace to make your prompt as token-efficient as possible.

Frequently Asked Questions — AI Prompt Sanitizer

How does this save ChatGPT tokens?

LLMs count every character, space, and markdown symbol as a fraction of a token. By stripping out 50 redundant empty lines, HTML tags, and formatting, you can easily save hundreds of tokens on large prompts.

Does it change the meaning of the text?

No. It only removes structural formatting and invisible characters. The actual words and content remain exactly the same.
