Turn study material into an interactive anime-style story.
Paper Playground is a web app that transforms uploaded PDFs or text files into a short interactive visual-novel-style experience. Instead of passively reading notes, users engage with the content through dialogue, characters, and choices.
Paper Playground focuses on learning through interaction.
Upload your study material → Choose a character → Generate an AI-driven story → Make choices → Continue the narrative.
