Duolingo utilizes advanced technology to create an engaging and interactive language-learning experience. The platform employs algorithms that adapt to the user's learning pace and style, ensuring personalized lessons that enhance retention and understanding.
The workflow is designed to be intuitive and user-friendly, allowing learners to progress through levels by completing exercises that include reading, writing, listening, and speaking. Users can track their progress, earn rewards, and compete with friends, making the learning process both fun and motivating.
However, there are risks associated with relying solely on Duolingo for language acquisition. While it provides a solid foundation, it may not fully prepare users for real-world conversations or cultural nuances, and learners may need additional resources or practice to achieve fluency.

Consider switching to Babbel: Babbel offers more structured courses and focuses on conversational skills.
The clearest current AI differences are Video Call and Roleplay, which add real-time spoken conversation and scenario-based AI practice on top of Super benefits. Explain My Answer started as a Max feature, but Duolingo now says it is free for most learners in supported courses. Duolingo does not expose numeric Max pricing on the public pages we could verify, so the upgrade decision mainly depends on how much you value the AI conversation tools.
Duolingo Video Call uses an AI character such as Lily for a spontaneous spoken conversation that adapts to your level. You can ask the character to repeat or slow down, and Duolingo provides transcripts or post-call feedback in supported experiences. Duolingo says calls can last about one minute for earlier learners and up to roughly three minutes as you advance.
Duolingo documents Video Call across nine popular language courses: English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, and Chinese. Duolingo Max is available on both iOS and Android, but exact Video Call character, Roleplay, course, and device availability can vary. The vendor continues to roll features out by course and platform, so availability in your account is the final check.
Yes. Duolingo's privacy policy says text and audio submitted to AI-enabled features may be shared with AI vendors such as OpenAI and Google. Duolingo says its agreements with those vendors do not permit them to use personal information for their own purposes.
Duolingo says it may generate, record, and store audio recordings or transcripts from Video Call and other AI-enabled features. The privacy policy says those recordings or transcripts may be used for product improvement and personalization, including training and running Duolingo's own AI models. The policy therefore does not support a blanket no-training claim.
Duolingo says users can choose in app settings not to share audio for product-improvement purposes. Its public privacy policy does not clearly document a complete opt-out covering all AI-feature text, transcripts, and model-training uses. For that reason, the broader AI-training opt-out remains unclear in our audit.
Duolingo Video Call is an AI conversation partner, not a live human tutoring service. Duolingo describes it as a low-pressure way to practice spontaneous speaking, with the character adapting to your level and responding in real time. It can add conversation practice, but the vendor does not document it as an equivalent replacement for individualized instruction from a human tutor.
Duolingo says human learning experts design the curriculum, define lesson goals, write prompts and instructions for its AI systems, and review or refine generated content. Its personalization models then select exercises based on a learner's strengths and weaknesses. Duolingo does not publish a product-wide error rate or guarantee that AI-generated content is error-free.
Duolingo Max uses Video Call and Roleplay for AI conversation practice, while Babbel Speak is a beta AI conversation partner built around guided real-world scenarios. Babbel's vendor pricing page lists its 12-month Individual plan at $8.95 per month, $107.40 billed for the year, and Babbel offers 14 languages overall. Duolingo offers a broader 40+ language catalog overall, although its AI conversation features are available only in selected courses.
Duolingo Max focuses on AI character conversations through Video Call and Roleplay. Busuu Premium Plus includes AI Conversations and pronunciation feedback, while Busuu Community lets learners receive feedback from fluent speakers. Busuu documents courses in 14 languages, so the tradeoff is a narrower catalog with a built-in human community feedback layer.
