Tips for error-free writing
- Read your text aloud. Your ear often catches what your eyes miss.
- Keep sentences short: one main idea per sentence is easier to read.
- Watch for commonly confused words: their/there/they’re, its/it’s, your/you’re.
- After fixing grammar, try the paraphrasing tool in Fluency mode to make your text flow even better.
