Record an async architecture walkthrough for your team
An async architecture walkthrough is a recorded whiteboard session where you diagram a system and narrate the design decisions so teammates can watch on their own time. Excalicast captures the diagram operations and your voice together, then exports an MP4 or (on Max) a lightweight replay link instead of a heavy video file.
Steps
- 1
Diagram the system
Sketch services, data flow, and boundaries on the Excalidraw canvas as you would in a design review.
- 2
Narrate the decisions
Record while you explain the trade-offs. The operation stream keeps the diagram crisp; your reasoning is preserved on the audio track.
- 3
Share async
Export an MP4 for any channel, or on Max generate a replay link that streams the operation stream + audio (10–20× smaller than a video) for recipients to watch in the browser.
FAQ
Why not just screen-record a Zoom call?
Screen recording captures pixels, so any overlapping window or notification ends up in the file and the result is locked to one resolution. Operation-stream capture stays clean and can be re-exported to any aspect ratio.
