FAQ
- Does the AI also improve writing style and flow?
- Beyond spelling and grammar, it flags clumsy style too, as optional suggestions. You accept or ignore each correction one by one, so if you only want the errors fixed, simply skip the style suggestions.
- Are corrections explained?
- Yes, automatically: every correction shows the original, the fix, the rule behind it and its category (spelling, agreement, punctuation, style…), to help you improve your writing skills.
- Does it work for languages other than English?
- This page proofreads English. For French, Spanish, Portuguese, German or Indonesian, use the version of the site in that language: each one corrects and explains the rules in its own language.
- How is this different from Grammarly?
- Grammarly underlines issues as you type; here you paste a finished text (or drop a file) and get every correction in one pass, underlined in place with its rule, to accept or ignore one by one. Many writers use both — a checker while drafting, this for the final deep pass.
- Will it change my writing style or voice?
- It doesn't rewrite your text: it proposes targeted corrections, and style changes are marked optional. You accept or ignore each one, so your voice stays yours.
- Can it proofread academic essays and papers?
- Essays, theses, and papers all work well, including citation-heavy text. It fixes the writing, not the facts — verify sources and data yourself.
