Linfo.ai

Linfo.ai is an AI summarization tool that turns articles, PDF reports, and videos into structured takeaways and mind maps. After a user submits a piece of content, the tool analyzes it and produces bullet-point summaries that link back to the original source, so a reader can click a takeaway and jump straight to the passage or video timestamp it came from. It also generates a mind map of the material, which can be exported as a PNG or JPG image, and lets users adjust how deep the content hierarchy goes depending on how much detail they want. The tool is aimed at professionals, students, and researchers who need to process large volumes of reading or watching material quickly. It works as a browser extension for Chrome, Edge, and Arc, as well as through an online dashboard, and it can summarize local PDFs and YouTube videos in addition to web articles. It also integrates with ChatGPT. Linfo.ai offers a free tier limited to 10 summaries per week, with a Pro subscription unlocking unlimited summaries and priority support. One limitation is that mind maps and hierarchy customization work well for text-based content, but the accuracy of video summarization depends on how clear the underlying transcript or audio is.
