What is ProWritingAid?
ProWritingAid checks grammar, spelling and punctuation and goes further with style and line-editing reports for fiction and long-form writing. The free plan includes the grammar checks plus two line-editing reports a day on up to 500 words, and ten AI rephrases a day. It works on the web, as a desktop editor, in Microsoft Word and in Google Docs. Premium plans lift the limits and are also sold as a one-time lifetime licence.
Pros
- Detailed style reports that go beyond grammar
- Works in Word, Google Docs and its own editor
- Lifetime licence option instead of a subscription
Cons
- Free reports are limited to short passages
- So many reports can feel overwhelming at first
