What ProWritingAid is
ProWritingAid combines inline grammar and spelling feedback with deeper reports for readability, repetition, sentence structure, and style. The extension is most useful when paired with the broader editor rather than treated as a lightweight spell-checker.
Feature coverage
- Grammar and spelling suggestions
- Style and readability feedback
- Paraphrasing and rewording tools
What stands out
- Detailed long-form analysis
- High store rating on a substantial sample
- Useful reports beyond basic proofreading
Tradeoffs to know
- Most advanced reports require a subscription

- Broad writing access deserves a privacy check
Permissions and privacy
Page access
Inline writing feedback generally requires access to text fields and page content on supported sites. Review the install prompt and limit site access when you are handling confidential drafts.
Data notes
Writing extensions can process the words you type. The store disclosure and linked privacy policy were the review baseline; re-check both before using unpublished, regulated, or identifying material.
Pricing
Free browser extension with paid Premium plans. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
