Question: I'm looking for a language learning app that supports multiple languages and offers realistic conversations with AI characters.

Talkio AI is a full-featured language training app that lets you practice speaking with AI tutors in a realistic conversation. It covers more than 40 languages and several dialects, with features like pronunciation practice, wordbook exercises and crosstalk with native speakers. The app is designed to simulate a supportive environment with human-like interactions, so it's good for people who want to work on speaking.

PrettyPolly is another AI-based service that lets you practice speaking with customizable AI characters. It covers 36 languages and offers personalized feedback, pronunciation evaluation and spaced repetition flashcards. It's freemium, meaning you can use it for free but a premium subscription unlocks unlimited conversations, so it's a good option if you want something that's flexible and not too expensive.

For a more immersive experience, AI LingoPlay uses lifelike AI characters in real-world situations to help you practice your language skills. It covers more than 10 languages and offers listening and speaking exercises, instant message analysis and translation tools. It's free to use, so it's a good option if you want to try something without paying up front.
