Question: Is there a language learning platform that supports multiple languages and offers a freemium model?

PrettyPolly is an AI-based language learning service that covers 36 languages and offers personalized feedback. It offers a freemium option with 7 free conversations, and a premium subscription for $6.50/month that lets you have unlimited conversations. The service is geared to help you improve your speaking skills with AI-generated scenarios and pronunciation evaluations.

Another good option is LangAI, which covers more than 20 languages and offers immediate corrections and feedback to help you improve your conversational proficiency. LangAI offers real-time error correction and natural-sounding conversations on any subject, with a free version that has a daily limit and a paid option for unlimited daily messages and full feature access.

If you want a more general-purpose learning tool, check out AITalk. The app covers more than 10 languages and offers personalized lessons, AI tutors and grammar checking. It also has an IELTS exam prep option and simulated conversations, so it's good for both everyday learning and exam prep. The app is free to use, but with some limits, and offers a paid subscription for full access.

Last, Lingotrack offers a freemium option with a free tier that lets you log unlimited activity and media for one language. The service combines sophisticated tracking abilities and a large library of media to help you track your progress and connect with other people. If you want to track multiple languages, a Pro subscription costs $3/month and adds more power to your learning.
