Paste your text to detect hidden characters and formatting issues that often cause weird spacing, broken bullets, and messy AI prompts.

Copying text from PDFs, Word, Google Docs, emails, or websites often introduces hidden Unicode characters and inconsistent formatting. These can break bullet lists, create odd spacing, or cause prompts to behave unpredictably in AI tools.
If you want to automatically fix these issues, open AI Text Cleanup.
What are invisible characters?
Invisible characters are hidden Unicode characters like zero-width spaces and non-breaking spaces. They are hard to see, but they affect formatting and can confuse editors and AI tools.
Why do bullets break after pasting?
Bullets often break because text contains mixed bullet characters (•, -, *, –) or inconsistent spacing. Paste Detector flags these issues and helps you fix them.
