What our online proofreader does

Grammar check

Finds incorrect verb forms, agreement errors, and broken sentence structure.

Spelling check

Missed words stand out immediately, including wrong variants that look “almost right.”

Punctuation check

Commas in the wrong place change meaning. Periods missing or doubled are flagged.

Sentence style and clarity

Mostly about readability. Long sentences, awkward phrasing, places where the idea gets lost.
