HomeGrammarly Introduces Grammar Correction for Spanish and French
For 16 years, Grammarly's linguists refined its grammar checker to follow natural English patterns. Now, AI helps the company launch support for five more languages: Spanish, French, German, Portuguese, and Italian. Grammarly’s VP of enterprise product, Luke Behnke, calls this the company’s most-requested feature since day one.
Beyond basic spell-check, the tool refines sentence structure and paragraph flow to match native tone and enhance clarity—now across six languages. It also translates content between these six core languages and 19 others without users needing a separate translation service, according to Behnke.
The market for non-English AI writing tools is growing competitive. Google Search's AI mode recently added five languages, and Apple's latest AirPods feature real-time translation.
Grammarly is expanding into broader AI productivity. This summer, it acquired the popular email app Superhuman and introduced nine AI agents for students and educators.
The company built its software on machine learning from the start. Behnke describes Grammarly as an "agent"—a term he admits is overused, but notes it was one of the first AI agents people adopted. The platform integrated large language models in 2023, fine-tuning open-source LLMs with input from analytical linguists.
Adding five languages didn't require linearly scaling the linguist team, Behnke explains. A compact internal group, plus rigorous testing and feedback, developed the new language models. All suggestions and rewrites come from these proprietary models, hosted on Grammarly's secure infrastructure under strict training protocols.

For advanced features, Grammarly supplements its own models with third-party LLMs. Users can opt to integrate an external model from providers like OpenAI. While third-party models don't train on user data, Grammarly's own models do—though enterprise and education accounts have training disabled by default, and individual users can opt out.
Behnke hasn't revealed which languages are next, but notes that customer support clients have asked for more languages in regions with offshore call centers.

¡Por fin! Como hispanohablante, siempre quise una herramienta como Grammarly para revisar mis textos en español. Me pregunto si manejará bien las variantes regionales (¡el español de México no es igual al de España!). Espero que la IA no 'invente' reglas gramaticales 😅. Esto podría ser un gran apoyo para estudiantes y profesionales.
