Overview
CowLoom is an asynchronous knowledge capture extension designed to automate internal SOP creation and tab recording workflows.
The Challenge
Standard screen capture tools are bulky, slow down browser processes, require paid cloud hosting, and fail to capture internal tab audio streams cleanly.
The Engineering Solution
Developed a Manifest V3 Chrome Extension utilizing MediaRecorder and Web Audio APIs. Engineered tab capture constraints, built popup menus, and designed a documentation portal using React/TypeScript.
Key System Deliverables
- ✦Chrome extension built on Manifest V3 background service workers
- ✦React popup UI and responsive web documentation pages
- ✦In-extension HTML5 canvas overlays for live recording statuses
Measurable Success
- ✓Accelerated internal team SOP recording workflows dramatically
- ✓Delivered lightweight background execution, zero-impact on browser memory
