ProWritingAid
What It Is
ProWritingAid is a writing assistant tool that combines grammar checking, style improvements, and deeper writing analytics. It’s often described not just as a grammar fixer, but a “writing mentor” because it gives feedback across dozens of reports (readability, pacing, consistency, overused words, etc.).
It works as a web editor, desktop app, or plugin (for Word, Google Docs, Scrivener, etc.), and you can copy-paste or write directly into it. It also has a browser extension.
Core Features & Capabilities
Grammar, spelling, and punctuation correction
Style suggestions: polish wording, avoid redundancy, improve clarity
25+ detailed reports (e.g. readability, pacing, overused words, sticky sentences)
“House style” and customizable rules: you can set your own preferences (e.g. always use Oxford comma)
Integrations: Microsoft Word, Google Docs, Scrivener, browser extension, plugin for many writing tools
Plagiarism checker (in higher/paid tier)
Word rephrasing and sentence rewrites (limited/free vs full access in premium)
Pros
Very rich feedback beyond simple grammar — helps you become a better writer
Customizable: you can tailor style rules to match your voice or house style
Great for long-form content, particularly novels, essays, or technical writing
Comparatively affordable with strong feature set
Many useful reports and diagnostics you won’t find in simpler tools
Cons
Free version is limited: many reports and edits are disabled or capped (e.g. limited word count)
It can feel overwhelming for beginners — too many suggestions and reports
Performance may slow down on large documents (some users report clunkiness over ~25,000 words)
Integrations are good but some are less seamless compared to competitors
No fully native mobile apps (major editing is done on web or desktop)
User Feedback & Observations
Some writers say ProWritingAid “found a bunch of mistakes I couldn’t see” and helped their writing flow better. Others caution that when your document is very long, the tool can get sluggish or overwhelming with suggestions.
Because of its depth, new users may feel submerged in the sheer volume of feedback. But seasoned writers often praise how it surfaces issues they’d never notice otherwise.
