Corrector App
Corrector App is a free online grammar, spelling and punctuation checker that works in English, Tagalog and more than 25 other languages, with no account or download required.
About
Corrector App is a free web-based writing tool that checks text for grammatical, spelling and punctuation mistakes. It addresses a common problem for writers: producing polished articles, emails, essays and other documents without errors that undermine credibility, particularly when writing in a language that is not one's first.
Users paste text of up to 15,000 characters into the online editor, select a language or regional variant, and the tool highlights errors along with suggested fixes. Clicking a suggestion applies the correction, and the tool also explains each mistake so writers can learn from it. The service is operated by a small team led by CEO Carla Falzoni, is built on LanguageTool technology, and is available in English, Tagalog and more than 25 other languages.
