Timer
A countdown the whole class can see.
Also used for: Countdown, PE
No separate tab, no one app per task. One panel that adapts to whoever is standing in front of it.
Not a generic toolbox: a dock designed around what a LessonUp lesson actually looks like, matching LessonUp's own look and feel.
The search bar matches not just a tool's name but also what it's for: type "wikipedia" and you'll find Reference. Typo-tolerant too. Plus a row of your most recently used tools, and a Favourites row you build yourself by dragging tools onto it.
Filter the dock by Primary, Secondary, Vocational or Higher ed, pick "Essentials" for the tools you use every lesson anyway, or put it together entirely yourself.
Save a class list once and load it with one click into Pick a name, Make groups, Attendance, Seating chart, the Spinner and the Calendar. Type names yourself, or import them in one go from a SOMtoday or Magister CSV export.
A read-aloud button on almost every part of the dock, including text straight from the lesson page. Detects Dutch or English on its own.
Seating chart, favourites, tool preferences and recently used tools are all kept, even after reloading the page.
Everything runs locally in your browser; nothing is sent to external servers. Microphone-based tools stay strictly local.
Every tool below is its own part of the dock, with its own icon and its own panel.
Search for what a tool does or a subject too, not just its name: try "wikipedia", "maths", "music class" or "pe".
No tool found. Try a different word, or browse all 67 tools above.
