High school and college students already using Quizlet
Self-directed learners who prefer interactive quizzing
Quizlet Plus subscribers looking to get more from their sets
Existing Duolingo users who want richer feedback and conversation practice
Casual and intermediate learners studying a widely supported language
Learners who want to build speaking confidence without a live tutor
Pros
Turned static flashcard sets into an interactive, conversational study session that adapted questions to the student's responses
Worked directly from a student's existing Quizlet study sets, so sessions could start without building new content
Powered by OpenAI models, giving it fluent, natural dialogue across a broad range of academic subjects
Fit neatly into the Quizlet ecosystem alongside other study modes, keeping learning in one familiar platform
Handled mainstream, well-documented topics reliably, making it useful for common high school and college coursework
Explain My Answer delivers contextual
GPT-4-generated breakdowns of mistakes, addressing a longstanding gap in Duolingo's core experience where feedback was often minimal
Roleplay and Video Call provide low-pressure conversation practice with an AI partner, letting learners rehearse speaking and writing without the anxiety of a live human
Includes all Super Duolingo benefits — ad-free lessons and unlimited hearts — so the AI features are additive rather than a separate app
Sits inside the same familiar gamified interface, so existing Duolingo users get new capabilities without changing habits or platforms
Cons
A meaningful share of responses were inaccurate or unhelpful, so students had to verify answers rather than trust them outright
Performance dropped noticeably on niche or nuance-heavy subjects where reliable source material was thinner
Locked entirely behind a Quizlet Plus subscription, with no access for free-tier users
The feature has been officially discontinued as of June 30, 2025, making it unavailable for new or ongoing use
AI features are only available for a limited set of courses and devices, so many learners studying less common languages won't get the headline benefits
At roughly double the cost of Super, the price premium is significant for what remains a supplementary set of features
It's not a complete path to fluency — serious learners will still need outside resources for deep listening, speaking, and grammar work
The conversation practice, while useful, is more structured and limited than a dedicated tutor or open-ended immersion tool
