AI summarizer
Summarize a PDF, a lecture or a video in seconds
LearnKit reads the whole source and writes a summary that follows its structure: one section per unit, the topics inside it and the key terms you need to know.
Free, no sign-up



Follows your material
Long documents are summarized unit by unit, so the last chapter gets as much attention as the first.
Key terms included
Every section ends with the terms and definitions worth memorizing.
Any source
PDFs, scanned pages, recordings, YouTube videos and articles all work.
Try it with your own material
No account, no download. Add a source and see the result in a few seconds.

Can it summarize a YouTube video?
Yes. Paste the video link as your source.
