Grammar and spelling are very important in books. Especially with self-publishing, as readers will deduct stars ⭐for mistakes. Some grammar is subjective and can vary by location, cultural influence, and historical factors.
There is help. Programs such as
Grammarly make suggestions. It can be added to Chrome and used with Google Docs. This is great for strengthening your writing.
Free information is on
hemingwayapp.com, which breaks down your writing and offers tips.
Before Grammarly, I relied on prowritingaid.com, which remains popular among Scrivener users, especially because it integrates with that app.
My favorite free resource is
wordcounter.net. There's a setting to allow proofreading, and various voice options are available. Hearing your manuscript is a superior way to spot mistakes. It's absolutely worth the time. I'd suggest pasting smaller scenes at a time, so if you hear a mistake, it'll be easier to find and fix. The site won't save your work forever, so be sure you aren't using it that way. There's a button to clear your work.
