Millions of people in the US write in more than one language every day. An email to a client goes out in English, a message to family in Spanish, a school form in French, and a group chat switches between all three. Most writing tools were built for one language at a time, which leaves bilingual writers either juggling several apps or skipping the check entirely. A multilingual grammar checker handles them all in the same place, so every message gets the same care whichever language it is in.
What Bilingual Writers Need From a Checker
- Automatic language detection, so you do not have to switch settings every time you change languages.
- Mixed-language support, because real documents often contain more than one language.
- More than spelling. Clarity, fluency and tone suggestions matter as much as catching typos.
- Translation in the same tool, for the moments you need to write something in a language you know less well.
- The same help on every device, from a laptop to a phone keyboard.

The Features in Detail
Here is how each part of the Spanish and French grammar checker fits into a bilingual writing day.
Grammar Checker
The red underlines that catch spelling and basic grammar mistakes work across more than 20 languages. The language is detected automatically, and several languages can sit in one document, so a bilingual report or a message that switches mid-paragraph is checked without any extra steps.
Advanced suggestions in six languages
In English, Spanish, French, German, Portuguese and Italian, blue underlines add advanced grammar, clarity, fluency and tone suggestions. These are the edits that make writing sound natural rather than merely correct, which is often what a second-language writer wants most.
Paragraph rewrites
For the same six languages, you can refine tone, style and flow in one click, rewriting a whole paragraph rather than fixing words one at a time. It is useful when a message is grammatically fine but sounds stiff or too formal.
Translator
The web translator lets you paste text, choose a target language and get a translation to work from, which is handy for checking how a phrase reads in a language you know less well.
In-line translation
In-line translation works where you are already writing: highlight the text, choose Translate, pick a language, then review and accept the result. It covers 19 languages and works across more than a million apps and websites, including Gmail, Outlook, Slack, Google Docs, Microsoft Word and Microsoft Teams.
Android app
On Android, spelling and grammar checks cover 24 languages, with clarity and fluency suggestions in the six main languages. That keeps texts and messages as polished as anything written on a computer.
Quick Answers
Does it recognize regional variants?
No. It does not distinguish between variants such as Brazilian and European Portuguese or Mexican and Spain Spanish, so keep an eye on regional vocabulary.
Is it only for people learning a language?
No. Fluency feedback is aimed at multilingual writers in general, including fluent speakers who simply want writing in their second language to sound as natural as in their first. Many people use it most for formal writing, where small slips are more noticeable.
Will it work in my email and documents?
Yes. The grammar check in other languages runs through the browser extension, the desktop apps for Windows and Mac and the mobile apps, and in-line translation works in tools such as Gmail, Outlook, Google Docs and Microsoft Word.
Can I use more than one language in a document?
Yes. Language detection is automatic and handles several languages in the same document.
In Short
Writing in two or more languages should not mean doubling your proofreading time. A single tool that detects the language, checks grammar, suggests clearer phrasing and translates in place lets you write confidently in whichever language the moment calls for. Turn on in-line translation for the language you use least, and let the checker cover the rest.
Multilingual checking, rewrites and translation all come with Grammarly, on desktop, in the browser and on mobile. You will find more reads on writing, work and everyday tools at TheVougeClub.
