User Reviews

Users broadly praise the add-on for strong grammar checking and ease of use, noting it helps with long-form writing and quick edits. However, there are consistent concerns about price and aggressive upgrade prompts. Some users report compatibility issues that can block site functionality or interfere with other add-ons and email. A privacy/permissions concern is also raised about clipboard access. Overall, it's seen as a capable writing assistant, but buyers should weigh cost, reliability on sites, and permission needs before using it.

Easy to install and easy to use; saves time
Practical tool for writing tasks and templates

Cons

Pricing and upgrade pressure; perceived cost is high
