Grammar & Spell Checker — Instant Corrections in Your Browser

Two fixes applied in one pass: an example

The grammar checker scans pasted text for spelling, grammar, punctuation and word-confusion errors, then applies your chosen fixes with a click. Take a typical offender: 'Their going to be late, and we cant wait forever.' Two issues surface. 'Their' is flagged as a their/there/they're confusion — the fix is 'They're,' the contraction of 'they are,' which is what the sentence means. 'Cant' is missing its apostrophe and becomes 'can't.' Click both suggestions and copy the corrected line — 'They're going to be late, and we can't wait forever.' — and it's done in about the time it took to paste.

Two habits make it behave. Set the dialect first: with US English selected, words like 'colour' and 'centre' get flagged as British spellings, and switching the selector to UK lets them pass untouched. Then mind the size — the free API takes about 20,000 characters per check, so a long report goes in section by section. And read every suggestion before applying it; the checker proposes, you decide. A sentence that's technically correct but odd will sometimes draw a flag you should ignore, and that's fine.
