What is Heuristica?
Heuristica is an AI learning platform centred on concept maps. A learner starts from a topic or imports a source, such as a PDF, a YouTube video, a web page, a podcast episode or papers from PubMed and arXiv, and the tool produces a map of the ideas involved. Any map can be expanded into flashcards scheduled with spaced repetition, quizzes with multiple-choice or short-answer questions, summaries, essays or structured notes, and one format can be converted into another. An AI chat lets users talk to their documents and pick between several language models, with saved prompts and custom instructions. Decks and quizzes can be shared with classmates. A free Basic tier limits the number of saved maps, while the Professional subscription unlocks stronger models and the complete toolkit.
