mapifast is an AI-powered tool that converts any YouTube video or PDF into an interactive, research-grounded mind map in under 30 seconds. It uses a multi-agent pipeline to extract knowledge, conduct per-node research from academic sources, and generate spaced-repetition quizzes.

Yes. mapifast offers a free forever plan with 10 tokens per month and basic mind maps — no credit card required. Paid plans start at $19/month (Pro) and $49/month (Business).

How does mapifast convert YouTube videos to mind maps?

Paste a YouTube URL into mapifast. The Architect agent extracts the video transcript and builds a hierarchical knowledge structure. The Researcher agent then grounds each node in peer-reviewed papers from arXiv. The result is an interactive, clickable mind map delivered in seconds.

Can I export my mind maps to Notion or Obsidian?

Yes. mapifast supports one-click export to Notion, Obsidian, Markdown, and PDF, with formatting fully preserved.

What makes mapifast different from other YouTube summary tools?

Unlike basic summarizers, mapifast uses a multi-agent system that produces structured, hierarchical knowledge graphs — not bullet lists. Each node is grounded in academic research. It also includes spaced-repetition quizzes with AI grading, Notion/Obsidian export, and a personal searchable knowledge base.

Does mapifast have an API?

Yes. Business plan subscribers get API access. mapifast also offers an MCP (Model Context Protocol) server for developers. See https://www.mapifast.space/docs/api for details.

Free AI YouTube summarizer — turn any video into a mindmap

What you get

mapifast is a free AI YouTube summarizer that turns any YouTube video into an interactive, fact-checked mindmap with deep research, citations, and Notion / Obsidian export. 10 free mindmaps every month, no credit card.

Most YouTube summarizers shrink a 90-minute video into eight bullet points and call it a day. mapifast keeps the structure intact: a multi-agent pipeline pulls the conceptual scaffold, grounds claims against arXiv and the open web, and renders an interactive mindmap you can drill into.
