Block reference

The block palette has 22 block types in three groups: seven in Content, seven in Media and eight in Interactive.

Content

  • Text - a paragraph of plain text or simple HTML.
  • Section header - a heading that breaks the lesson into parts.
  • Statement - a short callout in one of four styles: Highlight, Info, Warning or Success.
  • Quote - a quoted passage with an optional source.
  • Two columns - two blocks of text side by side, each with an optional image.
  • Table - a simple table with an optional header row.
  • Divider - a plain visual break between sections.

Media

  • Image - a picture, with a caption and an optional lightbox. Copy image prompt copies a prompt built from the lesson title and the caption, to create the picture in your AI chat.
  • Image section - an image paired with a title and text.
  • Slider - a carousel of images, each with its own caption.
  • Hotspot image - an image with clickable points that reveal extra content.
  • Video - an embedded video from YouTube or Vimeo, or a video file you upload (Pro).
  • Audio - an uploaded MP3 or M4A recording the learner plays in the lesson.
  • Attachment - a downloadable PDF file, with a label.

Interactive

  • Accordion - a list of titled items the learner opens and closes.
  • Tabs - the same idea as an accordion, shown as tabs instead.
  • Checklist - a list of items the learner can tick off.
  • List - short points under each other, with a bullet, tick, arrow or number in front of each one.
  • Flashcards - front-and-back cards the learner flips.
  • Hidden section - content revealed behind a label, such as "Show the answer".
  • Continue - a button that hides the rest of the lesson below it until the learner clicks it.
  • Survey - asks learners to rate the course. Answers go to your LMS reports and never change the score.

List

A List block shows short points one under another, each with a marker in front. Choose the marker at the top of the block:

  • Bullet - a dot in your course's primary colour. Use it for features, rules or examples.
  • Check - a green tick. Use it for benefits and results, such as what the learner will gain.
  • Arrow - an arrow in your primary colour. Use it for examples or pointers.
  • Numbered - a number in a circle in your primary colour. Use it for steps that follow in order.

Title is optional and appears above the points. Add item adds another point, up to 30 points of up to 500 characters each. Points are plain text, without formatting.

A List block in the block editor: the style buttons Bullet, Check, Arrow and Numbered with Check selected, the optional Title field and three points, with Add item below them
Pick the marker style at the top of the block, then type one point per field.

When the learner scrolls to the list, the points slide in one after another. If the learner's device is set to reduce motion, all points appear at once.

To turn existing text into a list, select it in a Text block and click List in the Turn into bar that appears under the field. A bulleted list becomes a Bullet list and a numbered list becomes a Numbered list; other text is split into one point per line or sentence. Smart split with AI can also suggest List blocks.

List or Checklist: use List for points the learner reads. Use Checklist when the learner should tick items off, for example tasks to complete before moving on.

Video

A Video block plays a video inside the lesson. Pick the source with the Link and Upload switch at the top of the block:

  • Link: paste the address of a YouTube, Vimeo or Loom video.
  • Upload: add your own video file. The video plays inside the lesson, no YouTube or Vimeo needed.

For a lesson that is just one video, use a lesson of type Video instead: see Add a video lesson.

Upload a video file

  1. Switch the block to Upload.
  2. Optional: under Quality, keep 720p (the default) or choose Sharp (1080p) - bigger file.
  3. Click Upload video and pick the file, for example MP4, MOV or WebM.
  4. Wait while the block shows Compressing... and then Uploading... with a progress bar. Cancel stops both steps.

The video is compressed in your browser before it is uploaded, so a large original from a camera or a screen recording is fine: only the compressed copy is sent. On some browsers compression is slow; the block then warns you and lets you choose Continue or Cancel.

After the upload you can play the video in the editor and see its size and how much of the course's video space is used. Use Replace video to swap the file or Remove video to delete it.

Limits:

  • up to 15 minutes per video on every plan,
  • Free: 1 uploaded video per account, up to 50 MB,
  • Pro: 500 MB of video per course and 5 GB per account.

Uploaded videos play in the preview, on review links and in saved versions of the course. On Free a second upload is refused with "The Free plan includes 1 uploaded video. Remove it or upgrade to Pro to add more." Replace video works when the new file fits in the 50 MB; otherwise remove the old video first. Links to YouTube or Vimeo work on every plan and do not count. See Free and Pro: what is included.

Warning

Uploaded videos travel inside the exported SCORM package, so the package grows with every video. Many LMSs limit upload size (often 50-100 MB). The Export step shows the Estimated size of the package - check your LMS limit before uploading. For long recordings, a link to YouTube or Vimeo keeps the package small.

Transcript, quiz and captions for a video

These options are in the editor of a Video lesson, under the video. They are not part of the Video block. An uploaded video can be transcribed with Transcribe this video (Pro) and then gets captions; for a linked video you paste the transcript yourself. With a transcript, Add a quiz after this video adds a quiz based on it. A connected AI chat can also read the transcript, because get_lesson returns it for the video lesson. In a presentation the new quiz needs Pro, like any lesson between slides. Step by step: Add a video lesson.

Audio

An Audio block adds a recording the learner plays right in the lesson - a short podcast, part of a lecture or a sound for a scene.

  • Formats: MP3 or M4A. Other formats, such as WAV or OGG, are rejected - export the recording as MP3 or M4A first.
  • Size: up to 3 MB per file, which is about 6 minutes of speech. The file also counts towards your course's media limit, like images and PDFs.
  • Upload: click Upload audio or drop the file onto the block. After the upload you can listen to it in the editor, and use Replace audio or Remove audio.
  • Caption: optional, up to 200 characters, shown under the player. Screen readers also announce it as the player's name; without a caption they use the lesson title.

The learner gets a standard audio player with play, pause, a progress bar and volume. The recording travels inside the exported SCORM package, so it plays in your LMS without any extra hosting.

Generate narration

No recording yet? An empty Audio block also shows Generate narration, which turns text into a voice recording.

  1. Click Generate narration. The text field starts with the text of the lesson's blocks, without formatting. If the lesson has no text yet, paste or write your own.
  2. Shorten or correct the text. One narration takes up to 5,000 characters, about 5 minutes of speech. For a longer lesson, split the text into several Audio blocks.
  3. Click Generate. The recording is added to the block as narration.mp3 and works like an uploaded file: you can listen to it, replace it or remove it.

The voice is the one chosen for the whole course in Settings > Narration, where you can play a short sample of each voice before you pick one. The voice reads the text in the course language. After each narration you see how many characters you have used this month.

Privacy: the text you narrate is sent to our text-to-speech provider to create the recording. See the Privacy notice.

Pro includes 60,000 characters a month (about 60 minutes of audio). Free includes a one-time trial of 3,000 characters per account (about 3 minutes); it does not renew, and when it is used up the block shows "You've used your Free AI narration allowance. Upgrade to Pro to generate more audio." Characters are counted when the recording is generated, so a narration you remove still counts. See Free and Pro: what is included.

If something goes wrong

  • You are not sure which block fits: start with Text, then use Smart split with AI on that Text block to split it into other blocks once you see the content.
  • A media block needs a file you have not uploaded yet: check the size and format limits in Images, files and media limits.
