Sources & files

Add a PDF, link or YouTube video

Build from your own material by uploading files, pasting links or pasting text.

What you can add

  • Documents: PDF, DOCX and TXT.
  • Images and scans: PNG or JPG, up to 20 MB.
  • Links: web articles, Wikipedia pages and single YouTube videos (lezrn uses the transcript).
  • Pasted text, like your own class notes.

YouTube playlists and channels don’t work. Paste one video link at a time.

When you create a topic

In the New topic window, paste a link into the subject box, or drop a file under or build from your sources. Use Paste text instead for notes.

Add to a topic you already have

  1. Open the topic and click Overview in the Tools panel. Find Sources and click Add a source. On a phone, use the Sources tab.
  2. Upload a document, paste a link, or paste text.
  3. Confirm. You’ll see progress like Reading your document, then a Source ready notification.

Adding a source costs 5 credits. Once it’s ready it opens in the reader as a Source chapter, and it steers new courses, the chat and the tools.
