+# Caption Animation
+
+Turn a transcript or voiceover into word-timed, scroll-stopping captions: each word pops in on the syllable, the active word highlights, and the text stays glued to the narration. Build the kind of captions that drive watch-time on TikTok, Reels, and Shorts — readable, on-beat, and inside the safe area. For short-form creators burning open captions onto vertical video.
+
+## When it activates
+
+- "Add animated captions," "make TikTok captions," or "karaoke captions."
+- "Word-by-word subtitles," "auto subtitles," or "highlight the active word."
+- "Burn in captions to a video" or "sync captions to a voiceover/narration."
+- "Turn an SRT/transcript into animated text."
+
+## Example prompts
+
+- "Turn this Whisper transcript into karaoke captions with a per-word pop."
+- "Restyle these auto subtitles into a branded, Hormozi-style reveal."
+- "Burn word-level captions onto my voiceover and export a sidecar SRT."
+
+## What's inside
+
+- `SKILL.md` — the transcribe → normalize → page → animate → place → export pipeline.
+- `references/word-timed-captions.md` — deeper guidance on word-level timing and animation.
