The desktop client places a suggestion surface over text fields in browsers and installed applications, so the same checks apply whether a paragraph is written in Word, an email client or a web editor. Suggestions are grouped into correctness, clarity, engagement and delivery, each with a short explanation, and document goals can be set so feedback is weighted towards the intended audience and tone.
The premium tier adds sentence-level rewrites, tone detection with adjustment suggestions, plagiarism detection against web and academic sources, and a personal dictionary with style preferences. Checks run through the cloud engine, so an internet connection is required while writing; the desktop client itself is installed from this package with the premium feature set already enabled.
Windows 10/11 x64, 4 GB RAM, 1 GB free disk space, internet connection for cloud checks
