Active Dictionary
by Active Dictionary Company LimitedActive Dictionary is a web app for learning languages through texts, captioned videos and PDFs. Learners can look up words in context, save vocabulary and review it with spaced repetition. An AI assistant helps explain the learning material, while speaking and writing practice provide opportunities to use the language. The service is designed for learners at B1 and above. Freemium: free access with paid features. YouTube study depends on available captions, PDF support depends on the document, and AI usage limits apply.
AI Depth Score Rationale
The product mentions AI ('AI Expert' feature) for conversation and contextual explanations, but implementation details are minimal and the core functionality (reading, saving expressions, dictionary lookup) works without AI. AI is assistive rather than fundamental to the product.
