What it fixes
- Spelling
- Including the pairs spellcheckers wave through because both words exist: their and there, its and it's, affect and effect.
- Grammar and agreement
- Subject-verb agreement, tense consistency, dangling modifiers, preposition choice, pronoun reference.
- Punctuation
- Comma splices, missing serial commas where they change the meaning, unclosed quotes, apostrophes in plurals.
- What it leaves alone
- Your voice. It does not rewrite correct sentences for sport or shift your register: if it is right, it stays.
Two modes, different ambition
General mode fixes what is wrong and leaves the rest. Academic goes further: as well as correcting, it flags constructions that are valid but out of register — colloquialisms, verbal tics, overused passive voice — because in a university paper those cost marks too. If you only want the errors, stay in general.
Why you see the differences
A checker that hands back a clean block of text forces you to trust it blind or compare word by word. Here it arrives marked: every change shows against the original. It is more work to read and it is the only way to learn from the mistake instead of repeating it next month.
Frequently asked questions
British or American English?
It follows whichever your text already uses rather than imposing one. What it will not do is leave a document half in one and half in the other, which is the error that actually looks careless.
How is this different from my word processor's checker?
A classic checker compares word by word against a dictionary and gets little right beyond spelling. This one reads the whole sentence, so it sees agreement, tense, preposition choice and punctuation, which is where nearly all real errors live.
Is it included in the free plan?
Yes. With or without a free account you can check 100 words a run, 2 times a day, in both modes. For longer texts or more runs, Pro or Unlimited.
Will it change my style?
In general mode, no: it corrects errors and leaves correct writing alone. In academic mode it does flag valid but out-of-register constructions, which is exactly what that mode is for.
