- How much of the writing help you can use each month: 2,000 uses a month (instead of 100 uses a month)Each time you ask Grammarly to rewrite, shorten or reword something it counts as one use. Ordinary spelling and grammar underlining does not count and is never limited.
- Rewrite a whole sentence for you: Included (instead of Not included)The free version underlines mistakes and suggests small corrections. The paid version can rewrite a clumsy sentence from scratch.
- Checks whether text was copied from elsewhere: Included (instead of Not included)Mostly useful for students and anyone writing for publication. Most people do not need it.
