Four-step workflow
For teachers and tutors
Record whiteboard lessons without building a studio
Draw, explain, add your voice or webcam, and download a focused lesson video from one browser tab. No separate whiteboard app or desktop recorder required.
Readable diagramsAuto-zoom keeps the current step large enough to follow.
Teacher presenceUse microphone audio and an optional webcam bubble.
Private workflowThe recording stays local until you choose where to share it.
Why it helps
A teaching video should follow the explanation, not the whole desktop
Most screen recorders capture everything: browser tabs, toolbars, notifications, and a large whiteboard that becomes tiny in the final video. That is workable for a software demo, but it creates extra editing work for a math derivation, language diagram, science process, or tutoring recap. The viewer needs to see the current idea clearly, not search a full desktop for the next line.
ExcaliRec keeps the canvas and recorder together. You choose the final aspect ratio first, then draw inside the visible recording frame. Automatic focus motion can follow the part of the whiteboard where you are working, so equations and labels remain readable. The result feels closer to a guided explanation than a raw screen capture.
This is especially useful for asynchronous teaching. Record a short worked example after class, explain a difficult homework step, create a revision clip, or answer a recurring tutoring question once. The optional teleprompter keeps your lesson structure nearby, while slides let you separate topics without opening another app.
1. Choose the lesson frame
Use 16:9 for courses and YouTube, or a vertical ratio for short revision clips.
2. Prepare the board
Add a title, starter diagram, or separate slides before recording if the lesson needs structure.
3. Teach naturally
Draw and speak while auto-zoom, laser pointer, and webcam bubble guide attention.
Practical checklist
Make recorded whiteboard lessons easier to watch
- Teach one outcome per video. A five-minute answer to one clear question is easier to reuse than an unstructured forty-minute board session.
- Write larger than feels necessary. Students may watch on a phone or beside their notes. Leave space between equations, arrows, and labels.
- Pause before changing sections. A short beat helps viewers process the final diagram and gives you a clean edit point.
- Use the webcam only when it adds trust. A face bubble can make tutoring feel personal, but it should not cover the working area.
- Check the downloaded file. Confirm the first and last seconds, audio level, text size, and aspect ratio before uploading it to your LMS or class channel.
ExcaliRec exports WebM locally. If your course platform requires MP4, use the WebM-to-MP4 workflow after recording.
FAQ
Whiteboard recorder FAQ for educators
Can teachers record a whiteboard lesson in a browser?
Yes. ExcaliRec combines a drawing canvas, microphone recording, optional webcam bubble, and local video download in one desktop browser tab.
Do students need an account?
No. Download the recording and share it through the learning platform you already use. ExcaliRec does not host student accounts or classes.
Which video shape should I choose?
Use 16:9 for course platforms and YouTube, or 9:16 for short revision clips. Other supported ratios include 4:3, 3:4, and 1:1.
Does my lesson upload to a server?
No. Recording and processing happen locally in your browser. The finished file downloads to your device.
