What is Heuristica?
Heuristica is an educational platform that functions as a multi-format content generator from a single source. Users input a PDF, YouTube video, or podcast, and the system utilizes a suite of AI models—including Gemini, Claude, and ChatGPT—to generate interconnected learning materials. It produces concept maps and structured notes, then enables one-click conversion into spaced repetition flashcards and quizzes. This architecture automates the creation of varied study aids from source material, including academic literature from repositories like arXiv, solving the problem of manually creating diverse learning assets. The platform is built for students, academic researchers, and educators. A researcher can initiate a literature review by summarizing multiple PDFs, while a PhD student can use the concept map generator to structure a dissertation proposal. For daily study, a student can input a lecture link to generate flashcards for spaced repetition or a quiz to test comprehension. While daily generation limits on the free account can restrict comprehensive writing projects, it effectively assists in processing and reviewing complex academic topics step-by-step.
