Praktika is a language‑learning app that pairs users with AI‑driven avatars designed to simulate natural, accent‑rich conversations. The avatars respond to spoken input, offering pronunciation feedback and adapting to the learner’s pace and goals. A multimodal feature lets users upload photos, audio, videos or documents, which the avatars use to create personalized dialogue and correction. The app also includes a library of over 1,000 lessons covering various topics and tracks speaking progress with metrics, streaks and challenges. Its learning model emphasizes real‑world conversation rather than rote memorisation.
