What You Can Add to a Lesson

A lesson can hold text, media, embeds and assessments. Add any of them with the + button in the lesson editor, or paste a link on an empty line: Learning recognises the links below and turns them into the right block.

Upload a file

Use the Upload block to add a file from your computer. It stays private to the people who can open the lesson.

File	Formats	Shows as
Image	.jpg, .jpeg, .png	The image, full width
Video	.mp4, .mov	A video player, with in-video quizzes if you add them
Audio	.mp3, .wav, .ogg, .m4a, .aac	An audio player with speed control
Document	.pdf	The PDF, readable in the lesson

Paste a link

Paste the link on its own, not embed code. The file or page must be shared so that your learners can open it.

Source	Paste a link like	Notes

Vimeo	`https://vimeo.com/<video-id>`	Counts towards video completion
Bunny Stream	`https://iframe.mediadelivery.net/play/<library-id>/<video-id>`	Counts towards video completion
Cloudflare Stream	`https://customer-<account-id>.cloudflarestream.com/<video-id>/watch`	The lesson completes on time spent, since its progress can't be tracked
Google Drive	`https://drive.google.com/file/d/<file-id>/view`	Share the file with anyone who has the link
Google Docs	`https://docs.google.com/document/d/<file-id>/edit`	Share the file with anyone who has the link

An image on any site	A direct link ending in .jpg, .jpeg, .png, .gif, .webp or .tiff	For example a file on Bunny or another CDN. A link with `?width=` and the like works too
Cloudflare Images	`https://imagedelivery.net/<account-hash>/<image-id>/<variant>`, or your site's own `/cdn-cgi/imagedelivery/...` link	Shows as an image
An audio file on any site	An https link ending in .mp3, .m4a, .wav, .ogg or .aac	Plays in the audio player. Signed links with a query string work too, for example from Bunny or Cloudflare R2
