Heuristica

Heuristica is an AI study and research tool that organizes learning around concept maps, flashcards, quizzes, notes, and conversations. Heuristica serves students, researchers, teachers, and lifelong learners who want to turn source material into formats they can review or explore. The service uses large language models, including models from ChatGPT, Claude, and Gemini, rather than relying only on a conventional text chat interface.

Heuristica connects visual exploration with study material creation. A topic can become a concept map, and that map can become flashcards, quizzes, study notes, or an essay. The same approach applies to imported documents and media, allowing learners to work with source material in different formats without having to create each study resource separately.

Heuristica provides tools for understanding source material, organizing ideas, and testing recall. Supported inputs include PDFs, YouTube videos, websites, podcasts, documents, and topics entered directly. Heuristica also draws on academic resources such as PubMed, arXiv, and Semantic Scholar. The available outputs cover visual maps, written explanations, structured review materials, and practice activities.

Heuristica starts with a source or a topic: users can add a PDF, paste a YouTube link, supply a website, or begin with something they want to learn. Heuristica then generates study materials through button-based actions rather than requiring users to write prompts. Users can continue by asking questions about the material or converting an output into a different study format.

Heuristica supports AI model selection, custom instructions, and saved prompts for users who want more control over conversations. Response language can be changed through the language settings menu. Professional subscription features include editing and integrations with Semantic Scholar, arXiv, news search, podcasts, and YouTube videos. Decks and quizzes can also be shared with classmates or colleagues.

Heuristica is intended for students, researchers, teachers, and lifelong learners. The combination of visual maps and review activities supports both exploring unfamiliar subjects and practicing material already studied. Research-oriented uses include developing a topic and organizing connected information, while classroom uses include preparing study resources and sharing practice materials. Heuristica also supports repurposing concept maps for classwork, research, or presentations.

Heuristica offers a free Basic plan and a paid Professional subscription. Basic includes GPT-5.4 mini, limited functionality, and a maximum of 3 saved concept maps. Professional is listed at $7.99 per month or $59.99 per year. Prices are stated in US dollars, and checkout shows the local currency. Professional adds access to more models, editing, custom prompts, and the broader study toolkit.

Heuristica allows subscribers to cancel at any time, with charges applying to the current monthly or annual subscription period. Subscribed users can manage their plan and download invoices through the Subscription button in the header or footer. The source also describes a YouTube walkthrough for learning how to use Heuristica and its features.

Heuristica combines source importing, visual organization, AI chat, and active recall tools in a single learning workflow. Cross-format conversion is a practical strength for learners who want to reuse the same material as notes, maps, flashcards, or quizzes. However, access depends on the plan, and Heuristica explicitly warns that language models can produce inaccurate information about people, places, or facts.
