User Reviews

Users appreciate the app's effective grammar and tone correction, convenient cross-app integration, and time-saving capabilities. However, many express frustration with the limited free usage, restrictive word count on premium, removed features, occasional slowness, and privacy concerns. Overall, it's a useful tool for quick text editing but has limitations that impact user experience, especially for larger documents and privacy-sensitive users.

Pros

Effective grammar and tone correction features that assist with professional and casual writing.
Convenient integration with other apps via system menu, allowing text editing across various platforms like Gmail, Instagram, and Facebook.
User-friendly and fast for quick grammar or spell checks before posting.
The app helps save time in writing and editing emails, social media posts, and other texts.
Free version provides daily usage limits, making it accessible without payment for basic needs.

Cons

The free version has a very limited daily usage (only 3 free checks), which frustrates users.
The premium version restricts editing to a small word count (around 200 words), which is too low for larger documents.
Some features have been removed or are missing, such as the Lengthen feature and in-app editing compatibility.
The app occasionally suffers from slowness and reliability issues, including non-intuitive interface elements and inconsistent functionality.
Privacy concerns due to inability to delete history of edited texts and lack of certain tone options (e.g., Formal, Casual).
