FAQ

Is my text uploaded?

No. Cleaning runs entirely in your browser.

Will code blocks be changed?

With “Preserve formatting inside code blocks” enabled, fenced code keeps its original indentation and spacing.

What about ChatGPT / Claude / Gemini output?

Extra blank lines and trailing spaces are the most common issues — those options are on by default.
