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. ## Key features - **Concept Map Maker**: Builds a visual map of a topic that can be extended node by node with AI. - **Flashcards with Spaced Repetition**: Creates cards from notes, PDFs, videos or maps and schedules their review. - **Quiz Generator**: Writes practice questions in multiple formats from any study material. - **Source Import**: Pulls in PDFs, websites, YouTube transcripts, podcasts and academic databases. - **Multi-Model AI Chat**: Offers chat with a choice of models and turns a conversation into cards or notes. - **Summaries and Study Notes**: Condenses lectures, pages and papers into key takeaways and organised notes. ## How Heuristica works 1. **Add a source**: Paste a link, upload a file or type a topic. 2. **Generate a format**: Choose a concept map, flashcards, a quiz, a summary or notes. 3. **Convert and review**: Turn one format into another, then practise with spaced repetition or quizzes. ## Use cases - **Starting a Literature Review**: A PhD student maps a research area from arXiv papers before narrowing a topic. - **Exam Revision**: A student turns lecture PDFs into a flashcard deck and reviews it daily. - **Lecture Catch-Up**: A learner summarises a long YouTube lecture and quizzes themselves on it. - **Lesson Preparation**: A teacher builds a concept map of a unit and shares a quiz with the class. - **Reading a Textbook Chapter**: A reader chats with the chapter PDF to clarify a difficult section. ## Things to know - **Output may contain errors**: The site warns that the language models behind Heuristica may give wrong information about facts, places or people. - **Free tier limits**: The Basic plan is restricted to one smaller model and three saved concept maps. - **Account email must match**: Paid features stay locked if the purchase email differs from the email registered on the site. ## FAQs ### What is Heuristica?
