Use tool ↗About Heuristica
Heuristica converts PDFs, videos, podcasts and links into branching concept maps that you expand node by node instead of writing prompts. The same uploaded source also generates flashcards with spaced repetition, quizzes, transcripts and structured notes. Paid users can switch the model behind it between several GPT, Claude, Gemini and Qwen options.

Pros & cons of Heuristica
Worth paying for if you genuinely think in maps, since the branching exploration is the actual product and the flashcards are a bonus. If you only want summaries and chat over a PDF, free options cover that already.
Pros
- Under $6/month is cheap for this category
- One upload produces maps, flashcards and quizzes together
- Model choice across four vendors on the paid plan
- Ingests YouTube and podcasts, not only PDFs
Cons
- Free plan stops at three saved concept maps
- Small indie project with no registered company behind it
- No API and no native applications
- Headline price assumes a full year prepaid
Best for
- Students mapping an unfamiliar field before exams
- Researchers tracing how subtopics connect across sources
- Turning lecture videos and podcasts into revision material
Not for
- Plain document question-answering, where free chatbots suffice
- Shared team knowledge bases, since this is a solo study tool
- Users needing offline access or native mobile apps
Watch out: The $5 figure is the annual-prepay rate; billed month to month the Professional plan costs noticeably more.
