GrammarBot

GrammarBot is a french grammar checker tool. An AI writing assistant for grammar checks, message rewrites, tone and style changes, and in-app translation, with support for English, Spanish, French, German, Ukrainian, Polish and Norwegian. Available as a free iOS download.

GrammarBot is a writing assistant built around three tasks: catching grammar and typo errors, rephrasing messages so they land more clearly, and shifting the tone of a piece between registers such as formal and casual. The pitch is straightforward: it targets people who want their written output to read the way a fluent native speaker would write it, rather than simply being technically correct. The rewrite function is where the product separates itself from a basic spell checker. Instead of flagging an error and leaving the fix to the user, GrammarBot offers reworked versions of a message so the meaning stays intact while the phrasing improves. The style transformation feature goes a step further and changes the voice of the text, which is useful when the same content has to serve a formal recipient and a relaxed one. Language coverage extends beyond English: the app also operates in Spanish, French, German, Ukrainian, Polish and Norwegian. A translation option sits inside the same workflow, so text can be corrected, restyled and moved into another language without switching tools. That combination suits multilingual users, students writing in a second language, and professionals who correspond across borders. Against general-purpose chatbots, GrammarBot is narrower by design: it does not attempt open-ended generation, research or long-form drafting. Its value is in short, frequent editing passes on messages, emails and posts. Anyone expecting a full document editor or a plagiarism checker will need something else alongside it. The app is free to download on iOS, which makes it easy to test before committing to regular use.
