About SmartPace - AI YouTube Smart Speed
SmartPace is a side panel extension that uses Anthropic Claude AI to analyze YouTube captions and automatically create a key-point summary and a per-segment playback-speed plan. Watch long videos faster, focused on what matters.
■ How it works
1. Open any YouTube video and click the SmartPace icon — the side panel opens.
2. Sign in with Google and click "Analyze" — no API key needed. (Free plan: 30/month, 5/day)
3. AI analyzes the captions and gives you two things:
- Key summary: the gist of the video in a few lines — copy it to your notes with one click
- Per-segment speed plan: the video split into 6~12 segments, classified by importance
· Key (1.1~1.3×) — first appearance of important concepts
· Normal (1.9~2.1×) — explanations, examples
· Filler (up to 2.0×) — intros, outros, repetition, ads, small talk
4. As playback crosses segment boundaries, the speed switches automatically.
■ Playback modes (beyond simple speed-up)
- All: play every segment at its own speed
- Skip filler: skip the less important parts — ads, intros, repetition, small talk
- Key only: play only the key segments and skip the rest
- Click any row in the segment list to jump straight to that segment
■ Modes
Pick the analysis tone that matches the content:
- Lecture / Education / Documentary / Talk / Tutorial / News
■ Plans
Free

■ Sign in & privacy
- Sign-in is handled by Google OAuth; we store only your email and analysis counts (for plan limits)
- YouTube captions are sent to our backend (Claude AI) only to generate the summary and speed plan; they are not stored
- Pro billing is handled by Lemonsqueezy (payment processor)
- No ads, no tracking, no telemetry
