Text copied from ChatGPT, Claude and Gemini can carry invisible characters, unusual spacing and formatting that looks harmless but causes problems in websites, search, code and content systems.
We built aitxt as a quick, focused tool that cleans everything in one paste. I shaped the product around making an invisible problem easy to understand, with a simple before-and-after experience that removes the unwanted formatting without getting in the way of the writing.
A huge thank you to everyone at Wolf & Hat Studio who kept finding strange examples to break it with, from hidden spaces and stubborn punctuation to Markdown copied straight from chat windows, and helped turn a small frustration into a tool we now use almost every day.
