COMMON QUESTIONS
Frequently asked questions
Does ChatGPT put hidden characters in every response?
OpenAI has publicly discussed text-watermarking research, but there is no verified public basis for claiming every ChatGPT response contains a hidden Unicode watermark.
What does this remover actually delete?
It removes only the Unicode controls and spacing artifacts selected in the form, and it runs locally in your browser.
