How to add a trending sound and captions in TikTok before posting
Oct 5, 2026
Your ChatGPT Millionaire AI video downloads as a watermark-free MP4 with the star's own lip-synced speech. Pairing it with the sound the meme is trending with earns you a spot on that sound's page, and captions carry the punchline for muted scrollers. Here's how to do it right.
Why post with the in-app sound
- Videos posted with the official trending sound join its sound page — extra reach a baked-in track can't get
- The in-app version is always the exact track that's trending this week, licensed inside the app
- Captions beat burned-in text: they're editable, translatable, and readable at any resolution
In TikTok
- Open TikTok → + → Upload → pick your ChatGPT Millionaire AI MP4
- Tap Add sound → search for the sound the meme is trending with (check this week's version)
- Make sure the sound starts at 0:00 and covers the punchline beat
- Add captions beat by beat: the question → the fantasy → the reality check
- Post with the trend's hashtags
In Reels and Shorts
Same principle: upload your clip, then add the trending audio inside the app. On Reels, pick the audio from a trending post so you land on its audio page; on Shorts, use the app's audio search.
