How to use this tool:

This tool highlights three common writing issues that can weaken your writing:

Weasel Words

Words that sound good without conveying information (very, extremely, various, etc.)

Passive Voice

Constructions where the subject receives the action rather than performing it

Duplicate Words

Repeated adjacent words (click on highlighted duplicates to remove them)

Note: The goal is not to eliminate all highlighted issues, but to make conscious choices about their use.
