speedctl

speedctl gives you precise control over video playback speed on YouTube with powerful rule-based automation. Features: • Set a default playback speed (0.5x to 3.0x) that applies to all videos automatically • Create per-channel rules — assign a specific speed to any YouTube channel • Define regex-based title rules — match video titles with regular expressions to set speeds automatically • Rule priority: Title regex rules > Channel rules > Default speed • Customizable keyboard shortcuts to quickly adjust speed while watching • On-screen speed indicator overlay with smooth fade animation • Popup for quick channel rule creation from the current video • Settings sync via Chrome local or sync storage • Clean, minimal options page for managing all your rules How it works: 1. Install the extension and set your preferred default speed 2. Optionally add channel-specific rules for channels you watch frequently 3. Add regex rules to match video titles (e.g., "tutorial" or "music.*official") 4. Use keyboard shortcuts (default: S to slow down, D to speed up) to adjust on the fly speedctl runs only on YouTube and requires only the "storage" permission — no data is collected or transmitted.
