Langua: AI language learning

What it does

Langua is an AI-powered language learning app designed to help users achieve fluency through conversation. Instead of just memorizing words, users engage in spoken dialogues with AI tutors on a wide range of topics, from general chats and role-playing scenarios to structured debates. The app provides real-time feedback, corrections, and seamlessly integrates vocabulary building by allowing users to save words from conversations directly into smart flashcard decks for later practice.

Where it shines

Langua excels at creating a tight loop between active practice and vocabulary reinforcement. The ability to tap any word during a chat and instantly save it to a flashcard deck (03:55) is a standout feature. Furthermore, the app leverages AI not just for conversation but also for content creation. At 09:12, the user generates a custom vocabulary list about 'Food' on demand, showcasing a powerful, personalized learning tool that goes far beyond static, pre-canned lessons.

UX highlights

Contextual Learning Tools: During a chat, users can tap words for definitions or get AI-suggested alternative phrasings (05:19), providing immediate, non-intrusive support.
Granular Chat Settings: The app offers deep customization for the learning experience, allowing users to change their AI partner, adjust speaking speed, and toggle settings like 'auto-send' (02:34).
Multi-Modal Practice: The flashcard system isn't just for review. It offers four distinct practice modes: Recall, Listen, Produce, and Chat (10:57), catering to different learning needs.
Integrated Help: A help icon within the flashcard practice modes (11:22) opens a bottom sheet explaining how the spaced repetition algorithm works, educating users on the learning science behind the feature.
Robust Filtering: The vocabulary list can be filtered by learning status, date added, and custom tags (08:50), giving users powerful tools to manage their study sessions.
Actionable Feedback: User-spoken text is not just transcribed; it's analyzed. Icons indicate correct responses (05:10) or offer corrections, making the feedback loop clear and actionable.

Monetization & growth

After a comprehensive onboarding quiz, Langua presents a soft paywall at 02:04. It offers two subscription tiers, 'Unlimited' and 'Communicate', with both annual and monthly options. The pricing is reframed into a daily cost (e.g., 'US$0.82 / day') to reduce sticker shock. A free trial is offered for both monthly and annual plans, encouraging users to experience the full feature set before committing financially. The app clearly positions the subscription as the path to unlocking its core, unlimited conversation practice.

Who it’s for

Langua is designed for intermediate language learners who have moved beyond basic vocabulary and want to build conversational confidence. The focus on role-playing, debates, and nuanced feedback suggests a target user who needs to practice applying their knowledge in realistic scenarios. It's ideal for those who feel stuck in the 'intermediate plateau' and need a consistent, patient, and available speaking partner to make progress.

Notes & opportunities

The app's feature set is impressively deep, but this can create some navigational complexity. For example, the distinction between 'Chat Settings' in the main settings menu (12:33) and the in-chat settings accessed from the chat screen (02:34) could be streamlined. Additionally, while the onboarding is strong, the final step is a feature explainer video (01:25) that feels slightly redundant after the initial video demo on the welcome screen. Simplifying this to get users to the main app faster could be a worthwhile experiment.
