Aces your exams with AI-generated mind maps
mapifast helps students turn YouTube lectures, recorded classes, and tutorial videos into interactive, fact-checked mind maps with built-in spaced-repetition quizzes and direct Notion / Obsidian export.
Cramming a 90-minute lecture the night before an exam is brutal. Re-watching it at 2x speed only goes so far when the slides aren't shared and the prof's tangents bury the key concept. mapifast solves the missing primitive: paste any YouTube URL and a multi-agent pipeline extracts the structure of the lecture, grounds every claim against arXiv and the open web, and renders it as an interactive mind map you can drill into. Compared to Mapify's static trees, ChatGPT's wall of bullet points, or Notion AI's flat outlines, mapifast is purpose-built for long-form learning.
5 ways students use mapifast
Visualize complex subjects
Turn dense organic-chem or macroeconomics lectures into clear hierarchical maps you can review in minutes, not hours.
Spaced-repetition quizzes
Auto-generated MCQ + short-answer quizzes per branch, graded by an LLM judge, so the act of self-testing is one click away.
Notion / Obsidian export
One-click sync into your existing study workspace with backlinks preserved — every node becomes a page.
Cross-lecture knowledge graph
Subsequent maps reuse prior research via the RAG layer, so concepts across courses link automatically.
Mobile review
Open the same mindmap on phone with bottom-sheet sidebars to revise during commutes.

Frequently asked
How does mapifast help students study better?
It converts long YouTube lectures into a visual mind map plus auto-generated quizzes, so you spend time understanding concepts instead of taking notes.
Can I export my mind maps to Notion?
Yes — native Notion export preserves the hierarchy as nested pages with backlinks.
Does it work for STEM lectures with equations?
Yes. The arXiv-grounded research agent attaches paper citations to formula-heavy nodes so you can verify the derivation.
Is there a free plan?
Yes — 10 mindmaps per month, no credit card. Most undergrads never need to upgrade.
What about lectures longer than two hours?
Pro plan handles long-form transcripts up to ~6 hours by chunking + cross-attention summarisation.
Can I share a mind map with my study group?
Yes — read-only share links and per-account collaborator grants.
Will it work with private / unlisted videos?
Only if you're the uploader and have transcripts available. Public + unlisted-with-captions both work.
Does it support languages other than English?
All major languages with YouTube auto-captions work today; UI is English-only.
