Follow these simple steps to make your text undetectable.
Unlike other "humanizer" websites that rewrite your text, Concealy takes a different approach. It does not change your text visually. Instead, it works by injecting invisible characters into the text, confusing AI detectors without altering what you see. This increases the text's length behind the scenes. Your wording, tone, and formatting remain exactly as you wrote them.
Start by selecting one of the three modes at the top of the page. For most users, Bypass + Clean is the recommended choice.
Makes text undetectable by AI detectors.
Cleans formatting and then makes it undetectable.
Only removes AI formatting like citations.
Paste your AI-generated content into the Input Text window on the left. You can use the button to add text from your clipboard.
By default, Word Compatible Mode is enabled. You can toggle it or use other options for more control:
This mode is optimized for Microsoft Word and other rich text editors. It adds more invisible characters to ensure features like spell check, font changes, and correct pasting work as expected. However, the `Ctrl + F` search may not work for phrases of more than one word.
This mode uses fewer invisible characters and is ideal for web-based platforms. The `Ctrl + F` search works perfectly, and there is no visible difference to users.
If you're in a cleaning mode, expand this section to choose exactly what to remove, such as citations, emojis, or markdown.
The processed text appears instantly in the Output Text window. By default, it's copied to your clipboard automatically. You can also use the button.
