Frequently Asked Questions

We support American English (US), British English (UK), Australian English (AU), and Canadian English (CA). Select your dialect in the dropdown to get region-specific suggestions, like "color" vs "colour" or "realize" vs "realise."

The writing scores rate your text on four dimensions: Clarity (how easy it is to understand), Engagement (how interesting and compelling), Delivery (tone and voice consistency), and Correctness (grammar and spelling accuracy). Each is scored from 0 to 100.

The tone indicator analyzes your writing style on a spectrum from Formal to Casual. It considers factors like sentence length, vocabulary complexity, use of contractions, and overall voice. This helps you ensure your writing matches your intended audience.
