Translate and save vocabulary words from any webpage into the user's DuoCards flashcard deck

Helps language learners capture unknown words encountered while browsing the web and seamlessly add them to their DuoCards vocabulary deck for later spaced-repetition study on mobile

1. User selects text on any webpage. 2. User right-clicks and chooses 'DuoCards' from context menu (or clicks the extension icon). 3. Extension opens/redirects to app.duocards.com/main/card with the selected word. 4. User reviews translation and saves the word to their DuoCards deck. 5. Later, the saved word is available for spaced-repetition study in the DuoCards mobile app.

Target users: Language learners using the DuoCards mobile app / People who encounter new vocabulary while browsing the web and want to save it for study

Cannot verify whether app.duocards.com requires login at the iframe level without live testing
Cannot determine if DuoCards mobile app or web service has paid tiers from extension source alone

Monetization

No paid features detected

The extension source code contains no payment logic, subscription checks, upgrade UI, billing API calls, or feature gating. The 'pro' keyword match in _locales/cs/messages.json is a false positive — it matches 'prohlížeče' (Czech for 'browser'). The extension is a simple bridge/launcher with no paid features of its own. The destination service (DuoCards app) may have premium tiers, but the extension itself does not gate any functionality.

Confidence: 80
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The store description explicitly states: 'Make sure you have DuoCards installed on your phone and have completed the registration before you start using this extension.' The extension embeds https://app.duocards.com/main/card via iframe (popup.html:15) and opens that URL via context menu (background.js:5). The core workflow of saving words to a personal deck requires a registered DuoCards account on the destination service.
