Rundownly is a desktop app that summarizes any YouTube video in under 10 seconds. Paste a link, pick your length, and get a clean timestamped summary without sitting through the whole thing.

It runs on your machine using your own Anthropic API key, so there's no cloud, no sign-up, and no subscription. Supports 11 languages, exports to Markdown, and costs less than $0.01 per summary. The whole app is ~4 MB.

Built with Tauri 2 + Next.js + Rust.
