FAQ

Can ChatGPT summarize YouTube videos?

Yes, but usually it requires third-party plugins or manually copying the transcript. mapifast does this natively and generates a structured visual map instead of a wall of text.

Why is a mind map better than a text summary?

Mind maps show the hierarchical relationship between concepts, making it easier for the brain to process, connect, and remember complex information compared to reading a linear text summary.
