01. The Problem

Engineers and students go to video platforms for 5 minutes of documentation or tutorials, but algorithmic recommendation hooks trap them for hours.

02. The Studio Hypothesis

Pennion designed a surgical, zero-latency DOM modifier that restores intentionality to video viewing without breaking search or subscriptions.

03. The Build

Engineered a pure vanilla DOM mutation-observer based Manifest V3 extension requiring zero runtime dependencies.

04. The Real Outcome

Transformed video consumption for focused learners into an intentional search utility with zero bloat.
