⏱️ Chapter Summary
Even for long videos, timestamped summaries appear progressively as they're completed — no need to wait for the entire process to finish. Both overall and chapter summaries are displayed simultaneously, and clicking a timestamp jumps you to that scene.
♾️ Unlimited YouTube Summaries
On-device processing automatically leverages GPU and NPU for fast summaries, and works on CPU alone when GPU/NPU is unavailable. No external APIs means no rate limits or network latency — summaries start automatically the moment you open a video.
