SmartPace - AI YouTube Smart Speed

About

```
SmartPace is a side panel extension that uses Anthropic Claude AI to analyze YouTube video captions and automatically set the optimal playback speed for each segment.

■ How it works

1. Open any YouTube video and click the SmartPace icon — the side panel opens.
2. Enter your Claude API key once and click "Analyze."
3. AI splits the video into 6~12 segments:
   - Key segments (1.1~1.3×) — first appearance of important concepts
   - Normal segments (1.9~2.1×) — explanations, examples
   - Filler segments (up to 2.0×) — intros, outros, repetition, ads
4. As playback crosses segment boundaries, speed switches automatically.

■ Modes

Pick the analysis tone that matches the content:
- Lecture / Education
- Documentary
- Talk / Interview
- Tutorial
- News

■ Bring Your Own Key (BYOK)

SmartPace uses your own Anthropic API key. The key is stored only in Chrome local storage; analysis costs are billed to your own Anthropic account. No proxy server in between.
