Frequently Asked Questions

What is a good Flesch Reading Ease score?

A score between 60 and 70 is considered standard plain English (easily understood by 8th and 9th grade students). Scores above 70 are fairly easy, while scores below 50 are best suited for college graduates or specialized technical literature.

Why is passive voice discouraged in business and web writing?

Passive voice often obscures who is performing the action, making sentences longer and less direct. Active voice creates clearer, more engaging copy with higher readability and conversion rates.

Is my confidential writing saved or sent to any server?

No. All text parsing, syllable calculation, and passive voice scanning happens 100% locally in your device memory via client-side JavaScript.
