Shorts Composer
Clip, caption & highlight YouTube videos with Q/E keys
What it does
I kept losing track of good moments while researching YouTube videos for Shorts. Built this to fix my own workflow.

We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
