Show HN: PrepareYourself – Generate flashcards, quizzes, and summaries with AI

I built this while trying to learn Vietnamese. Most flashcard tools make you sign up before letting you do anything. This one doesn't – just paste your text and go. No account, no email, no friction. Paste any text (job description, study notes, documentation) and get: - Flashcards with Q&A pairs - Multiple choice quizzes with explanations - Bullet-point summaries Works in 11 languages. Export to PDF, DOCX, JSON, or TXT. Free to use (5 generations/day). Would love feedback on the output quality – especially from anyone learning languages or prepping for exams/interviews.
