An AI text cleaner takes messy model output and returns clean, human reading copy. Remove AI Tells is a free AI text cleaner that fixes the punctuation a model inserts, strips invisible characters copied from a chatbot, swaps the words that read as machine made, and scans for hidden prompts buried in what you paste. You get a human score and text you can publish. The first 300 words are free with no sign up.
Most cleaners stop at find and replace on a few characters. This one reads the whole thing, including the parts you cannot see.
What an AI text cleaner does
Four jobs. It normalizes the punctuation, converting em dashes, curly quotes, and stray ellipses to plain characters. It removes invisible characters like zero width spaces that chatbots leave behind. It replaces the small set of words a model overuses. And it evens out the flat rhythm that marks writing as machine made.
How the AI text cleaner removes hidden characters
Copy text from a chatbot and you often copy more than you can see: zero width spaces, non breaking spaces, and other invisible marks that break formatting and flag your content. The cleaner finds every one and clears it in a single pass, so what you paste out is exactly what you meant to keep.
The scan no other AI text cleaner runs
Beyond invisible characters, this tool reads your text for hidden instructions. A hidden prompt is a command placed in white or invisible text that a model reads but a person cannot see, and it can quietly change your output. Remove AI Tells flags it on every check.
