Excalicord

• Turned sketching, explaining, recording, and saving into one continuous workflow.
• Made the product feel closer to real walkthrough production than either a plain whiteboard or a plain recorder.

• Extended a familiar whiteboard core instead of rebuilding the canvas from scratch.
• Made scenes, teleprompter, reference media, camera bubble, and sync part of one coherent workspace.

• Live prototype exposes scenes, teleprompter, reference source, camera bubble, preview frame, and sync panels.
• Current deployed title still references 20260331-excalicord-base, showing an evolving standalone build rather than a one-off mockup.

• Owner / Product Engineer: defined the explain-workflow product boundary and integrated canvas, recording, and sync capabilities.

• Whiteboards are good at drawing and recorders are good at capture, but explanation workflows need script, reference, camera, and framing together.

• Support tools had to stay present without overwhelming the canvas.
• Recording permissions, camera state, and draft sync all introduce fragile UI states.

This was not about making another whiteboard. The trigger was the real explain workflow: whiteboard, script, reference media, camera, and screen recording usually live in separate windows.

• Record whiteboard explainers with a presenter camera and script.
• Walk through product ideas while referencing a live browser tab or local video.
• Keep asynchronous explanation projects editable, not just exported.

• Scene list for segmenting an explanation into reusable beats.
• Teleprompter, reference panel, camera bubble, and preview frame in one workspace.
• GitHub sync for saving and continuing project state over time.

• The product behaves like a presenter workspace, not a generic canvas clone.
• Assistive layers stay hideable so the canvas remains the center of attention.
• Desktop-first constraints are intentional because recording and multi-surface control matter.

• Built around an Excalidraw canvas with custom rails, teleprompter, media panels, and recording overlays.
• Uses browser media APIs for camera, screen-sharing, recording, and export workflows.
• Adds repo/branch/path-based GitHub sync to turn recordings into maintainable project files.

• Live prototype: https://excalicord.zondev.top.
• The current experience is explicitly desktop-oriented.
