Tips for better writing
- Do not add a comma just because you pause while speaking.
- Use apostrophes for contractions and possession, not for plurals.
- Check whether two complete clauses need a period, semicolon, or conjunction.
- Read the sentence around every highlighted suggestion before applying it.
- Keep names, product terms, and specialist vocabulary when they are intentional.
- Use the focused checker first, then use the broader editor for a final pass.
- Copy the corrected version only after checking that the meaning is unchanged.
