Text, formulas, video, interaction: one editor holds it all.
Lessons are written where they live. Rich blocks, real-time co-writing, automatic version history, a math editor and graded interactive exercises, without leaving the page.

- What is compound interest?
- The formula, worked
- Exercise: true or false
The formula, worked
With compounding, each period's earnings join the principal and earn with it. The gap against simple interest widens every period.Amy

Compound interest pays the same amount every period.Mark
Rich content without a second tool
Type a slash and insert what you need. Every block lives in the lesson itself.
Tables and columns
Real tables with row and column menus, plus multi-column layouts for side-by-side content.
Images and video
Drag a file in; it uploads straight to storage and renders with captions. Video playback picks up where the learner left off.
Code with highlighting
Code blocks with syntax coloring, for technical training that shows real code.
Structure that navigates
Headings feed an automatic table of contents; task lists and collapsible sections keep long lessons readable.
Written together, in real time
Two authors in the same paragraph is an ordinary day, not a support ticket.
- Live co-writing. Everyone edits the same document at once and sees each other's cursors. No locking, no "who has the file".
- Nothing overwrites. Changes merge at the character level. Two people can edit the same sentence and both edits land.
- Presence. You see who is in the document while you write.
Every version kept, automatically
You never press save. The history builds itself.
- Automatic snapshots. The document is snapshotted as you work; each snapshot is immutable.
- Preview and restore. Open any earlier version, read it, bring it back with one action.
- Course-level revisions. Beyond documents, the whole course has a revision history with point-in-time restore, and a clean draft-publish line.
A real math editor
Write inline and block formulas with a symbol palette, the way you would write them on a board. Built for courses where the content is the equation itself, not a screenshot of one.
Interactive exercises, embedded in the lesson
All eleven interactive types drop directly into the text: multiple choice, drag and drop, branching scenarios, interactive video and more. They are graded where they stand, and the result can drive the automation flow: pass the exercise, unlock the next module.
Open a lesson and try the editor.
Invite a colleague into the same document and watch both cursors move. That is the moment this page is trying to describe.
