With Little Language Lessons (https://labs.google/lll/fr), Google offers three tools, based on Gemini, to support language learning:

• Tiny Lesson: “lessons” with vocabulary, expressions and grammar tips based on a theme in one of the 22 languages available
• Slang Hang to learn common expressions from a written and audio conversation generated between two native speakers from 13 available languages and with translation as needed.
• Word Cam to acquire vocabulary from a photo taken via the camera or webcam.
