Issues

Checks run locally with an English dictionary, plus homophones and repeats.

Spellcheck flags typos, common grammar slips, and repeated words using a dictionary in the browser. Your writing is not sent to a grammar service.

It misses tone, names, and context. Read the draft yourself before you send it.

Questions

Is this an online grammar API?

No. The dictionary loads into this browser. The text is not uploaded.

Will it fix every sentence?

No. It marks common mistakes. It is not a full editor.
