Input (with errors): "The team are going to there meeting, but they wasn't sure if they should bring they're laptops. Its fine either way — you can present orally to."
Subject-verb agreement
The team are → The team is
"Team" is a collective noun and takes singular verb in US English. (UK allows plural — toggle if you prefer.)
Homophone confusion
there meeting → their meeting
"There" is a location; "their" is possessive. Owning a meeting needs the possessive form.
Verb tense mismatch
they wasn't → they weren't
Plural subject "they" pairs with plural verb "weren't". "Wasn't" is singular.
Possessive vs. contraction
they're laptops → their laptops
"They're" = "they are". Laptops aren't a state of being; need possessive "their".
Apostrophe (it's vs. its)
Its fine → It's fine
"It's" = "it is". "Its" is possessive. Here you mean "it is fine".
Word choice (to vs. too)
present orally to → present orally too
"Too" means "also". "To" is a preposition. You mean "orally, as an alternative".

We return a list of concrete issues with explanations, not a black-box "rewrite everything" suggestion. The corrected text only changes what was wrong. Your sentences, idioms, and voice stay intact.
Yes. Toggle US or UK before running. We respect whichever variant already dominates your text rather than forcing a switch.
Spelling, subject-verb agreement, tense, punctuation (commas, apostrophes, semicolons), word choice (affect/effect, its/it's), run-on sentences, and misplaced modifiers. Style suggestions are marked separately — you can ignore them.

Yes. We do not rewrite content or invent ideas — we only point out mechanical errors. Your thesis, evidence, and argument stay yours. Check your institution's policy on proofreading assistance.
No. This is a proofreader, not an originality checker. For that, you need a dedicated plagiarism service with database access.
No. Inputs are only sent to our inference provider and are not used for model training. Results are cached for 7 days to avoid paying twice for identical text.
English is the primary focus. Spanish, French, German, and Japanese grammar checking are rolling out — the Translator tool handles those in the meantime.
