Show HN: I created an AI app that creates endless language learning scenarios

I created LinguaLearn.ai to solve the repetitiveness of traditional language learning methods. It generates dynamic conversation practices across 30+ languages (including less common pairs like Korean→Spanish), with customizable scenarios and difficulty levels (A1-C2) delivered in WAV format accompanied by a transcript. The courses are similar to those produced by the Foreign Services Institute in the mid-20th century, which are very effective.

Tech stack highlights:

- Natural conversation generation in any scenario

- Cross-language learning support (learn any language from any language)

- Infinite number of scenarios (you can be really specific and i.e. try "restoring antique barometers from the Victorian era" or for a laugh you can try "falling out of plane and encountering amazon women").

- High-quality audio generation

- Difficulty-aware content generation (CEFR levels A1-C2)

- Full transcript generation

Currently in beta, offering 5 free lessons/month.
