TalkTrack-- 是做什么的？
A Codex Skill for proposal presentations. It takes PDF, PPT, or image-based proposal documents and generates a synchronized companion PPT that mirrors the original page numbers: thumbnails and keywords on the left, presentation-ready Chinese narration text on the right, and bottom cues for pauses, page turns, continuous speaking, and places that need manual elaboration. It's ideal for design, branding, product, planning, public presentations, and any last-minute proposal file. The goal is simple: let a non-professional with no preparation time still deliver a presentation that is at least passable.
