Youtube Links And Chapter

A simple extension that shows video chapters in a popup so you don't have to dig through the description.

What's new:

- AI Chapter Generation — For videos without chapters, use AI to automatically generate chapters from the video transcript. Supports clipboard mode (copy transcript to use with any AI) and direct API mode (connect to any OpenAI-compatible API like local vLLM/Ollama).
- Video Speed Controls — Quickly adjust playback speed directly from the popup. The current speed is shown in the button label.

What it does:
- Shows chapters for the current video
- Click one to jump to it
- AI chapter generation for videos without chapters
- Video playback speed controls
- Quick links to Home, Subscriptions, Watch Later, History
- Alt+Y to open (customizable in chrome://extensions/shortcuts)
- Works with dark mode
