Writing Tools FAQ
Why is passive voice considered bad in writing?
Passive voice (e.g., "The ball was thrown by John") is often less engaging and wordier than active voice ("John threw the ball"). Our detector highlights these instances so you can make your writing more direct and energetic.
What is a good readability score?
For general web content and blogs, aiming for a Flesch Reading Ease score between 60 and 70 (understandable by 13- to 15-year-old students) is ideal. This ensures your content is accessible to a broad audience.

No. Just like our other tools, all text analysis is performed locally in your web browser. Your unpublished drafts, essays, and articles are completely private and never uploaded to our servers.
