1. User browses any website and selects a word. 2. Extension injects a popup/tooltip showing word definitions from multiple dictionaries (Eng-Eng, Eng-Viet, examples). 3. User can listen to pronunciation audio. 4. User clicks the '+' button to save the word as a flashcard via an embedded study4.com iframe. 5. Saved flashcards can be reviewed later on study4.com/flashcards/ using spaced repetition.

- 目标用户
- English learners (especially Vietnamese speakers) / Students preparing for English exams (TOEFL, IELTS, etc.) / Users of the study4.com platform
- All JS source files are minified (webpack bundles), making it difficult to trace exact login/auth and payment logic within the extension
- The extension's core UI is loaded via iframe from study4.com, so key functionality and any auth/paywall behavior lives on the server side and cannot be inspected from the extension source alone
- Cannot confirm whether study4.com requires login or has paid tiers without accessing the live service

- The extension's popup UI loads an iframe from https://study4.com/extension/ (popup.html line 1), and the flashcard-saving workflow embeds https://study4.com/extension/add-flashcards/ in an iframe (frame.html line 1). These are destination-service pages served by study4.com. The store description says users can 'save flashcards instantly and later review on https://study4.com/flashcards/', which implies persistent user-specific data stored server-side. No login UI, cookie, session, or account handling exists in the extension source code itself—authentication, if needed, would occur within the embedded study4.com pages. Basic word lookup uses third-party dictionary APIs (Cambridge, Glosbe, Laban, etc.) and likely works without login.
