Hi,
Wanted to show off my app LangTrak which utilizes a lot of Google’s AI tech to its current potential in the service of learning languages.
A2UI for vocab and grammar practice
A2UI is being deployed to generate quizzes related to vocab and grammar in real time.
There is also the use of gemini flash and gemini embedding in addition to the fact that the UI is rendered with A2UI.

Agent Dev Kit (ADK) for Speaking Practice
The AI tutor will be able to see and discuss the exercises with you.
Also Nano Banana Pro is rendering high density text for personalised exercises.

Currently there is
French,
Spanish,
German,
Finnish and Russian.
I’ve got a lot of help from these forums to develop the app this far, so if any of you wish to use the app, use the LANG2026 to get two months of free access to premium features.
