Linfo.ai
Linfo.ai is a summarization tool for articles, PDFs, and YouTube videos. It reads full pages and returns structured takeaways plus an optional mind map, so you can scan long material without losing the thread of the argument.
The product ships as a Chrome extension (also listed for Edge and Arc) and as a web dashboard where you can paste text, upload PDFs, or summarize YouTube links. Takeaways are organized in expandable branches, and you can click any bullet to jump back to the matching passage in the source.
Linfo.ai also turns the same output into a mind map you can expand, collapse, or download as PNG or JPG. A free Basic plan includes 10 summaries per week; Pro unlocks unlimited article, PDF, and YouTube summaries with priority generation.

How do I summarize a local PDF?

Can I switch between takeaways and a mind map?
Yes. Linfo.ai lets you toggle between an insight (text takeaway) view and a mind map view for the same content, and you can regenerate either format from the extension.
