I built a local‑first YouTube note‑taking tool with timestamped screenshots

Thanks for checking out my project!
A bit more context: I built this tool because my son was struggling to follow a Japanese origami tutorial on YouTube. Pausing, rewinding, and remembering each step was harder than it should be.

Tech stack:
• Pure front‑end (local‑first)
• No backend, no database
• Everything runs in the browser
• Privacy by default — nothing leaves the device

My goal is to make learning from videos easier, especially for tutorials and long educational content.
Happy to answer questions or hear any feedback!
