About Rayo: AI Flashcards
After searching for a long time, I found that there isn't a flashcard app on the market that allows me to "extract content using a web plugin" and also "listen to it as a podcast on the go." As an independent developer, I really dislike complicated processes, so in Rayo: no login, no card binding, and completely free to use without time limits. 【Select on Computer, Instantly Create Cards】 Forget about copy-pasting! With our exclusive free browser plugin, while watching YouTube or browsing the web, just "select key content" to directly generate well-formatted flashcards. 【Your Portable Knowledge Podcast】 Who says reviewing can only be done by staring at a screen? Rayo supports background audio playback, so you can use it while commuting or exercising with headphones, completely freeing your hands. 【Capture Easily, Minimal Experience】 Open the app and swipe left or right to review. It supports database imports, photo card creation, or directly exploring the built-in theme flashcard library. Many exciting ideas will be added in the future, and I hope Rayo can continue to accompany you in your learning journey! --- Related Links - Rayo Homepage: https://rayo.pse.is/8ugdr3 - Download the free desktop plugin: https://rayo.pse.is/8ughfh
