Frequently Asked Questions
Get clarity on how our personalized vocabulary builder works.
How does the AI generate questions from my uploaded text?
The AI analyzes text structure, identifies key entities (words/phrases), and synthesizes concepts into robust question/answer pairs designed for active recall.
What file types can I upload for vocabulary extraction?
We support comprehensive input formats, including PDFs, DOCX files, PowerPoint presentations, and common image formats like JPG or PNG containing readable text.
Is using these custom AI flashcards better than using existing online vocabulary decks?
