Grammar & Proofreading

Catching what a writer stops noticing after repeated rereading is the remit of grammar and proofreading software. These tools scan finished text for spelling, punctuation, agreement, tense, article use, run-on sentences and misplaced modifiers, then propose corrections with an explanation of the rule. Beyond outright errors, most flag style matters: passive construction, wordiness, repeated sentence openings, inconsistent capitalization, hyphenation and regional spelling conventions. Custom dictionaries, style guide enforcement, readability scoring, inline underlining and exportable reports are common.

Editors, academics, legal and compliance reviewers, support agents and people writing in a second language rely on this category, usually as the final pass before publication or submission. Selection turns on detection accuracy against false alarms, whether corrections explain themselves, support for specialist vocabulary, enforcement of an organization's own style sheet, coverage across editors and browsers, on-device operation, and terms covering documents submitted for checking.

Judge a checker on text containing deliberate edge cases, including proper nouns, technical terms and intentional fragments, and weigh wrong flags as heavily as missed errors. Confirm that dismissed suggestions stay dismissed. Weaknesses include over-correction of legitimate stylistic choices, poor handling of quoted material and code, and blindness to sentences that are grammatically clean but factually wrong. Free browser checking, individual subscriptions, per-seat business plans and document-based pricing are the usual shapes.
