Numerous Reddit threads in r/Anki, r/study and r/languagelearning (10+ posts between 2023-2025, e.g. “I made a tool to generate Anki Flashcards from YouTube videos”, “Built a free AI tool that turns PDFs, notes & YouTube videos into Anki…”, “New Tool I’m building: turn YouTube videos into Anki flashcards”) show repeated interest and positive feedback (‘would pay for this’, ‘lifesaver, made 65 cards in 5 min’).
