Who it is for

Grammar & Spell Fixer is for text that needs correcting without being rewritten: an email, a report, an application, or a document written in a second language. It is used where the voice matters and only the mistakes should change.

How it works

The AI makes the minimum changes needed for correct, natural writing rather than restyling the whole passage.
Spelling, grammar and punctuation are corrected, and awkward phrasing is smoothed where it is clearly wrong.
The correction is returned as text you can compare against your original.

What it cannot do

It can change your voice along with your mistakes, particularly in a distinctive or informal register.
It will not catch a factual error; a well-written false sentence comes back clean.
British and American conventions can be mixed if the text does not make its variety clear.
The text is sent to a third-party AI provider.

Frequently asked questions

Will it rewrite my style?

No. It preserves your meaning, voice, and formatting and only makes the minimal corrections needed — it does not paraphrase or restructure your writing.

Which languages does it support?

It corrects text in the language you paste, keeping that same language in the output rather than translating it.

Does it show what changed?

It returns the corrected text directly so you can paste it straight in. Compare it with your original to spot the edits.

Is my text stored?

No. It is sent securely only for the correction and is not kept on our servers afterward.

Does it keep British or American spelling?

It follows the spelling already in your text where that is consistent, but a short passage with no clear convention may come back in either. State which variety you want if it matters.

Will it flag what it changed?

Only by comparison. The corrected text is returned without a diff, so keep your original open in another window if you need to see exactly which words moved.
