Symphony

Symphony is TikTok's suite of AI tools for making ad videos, from scripts to full generated clips.

It can write and storyboard ideas, generate video, and put a digital avatar on screen to read your script. The stock avatars are built from paid, licensed actors, and the dubbing tool detects your video's language, transcribes it, and produces a translated, dubbed version so one clip can speak to several markets.

For example, you have one product video in English. You run it through Symphony's translation tool to dub it into 10 or more languages, then use a stock avatar to record extra variations without hiring a crew or booking a shoot.

AI-made does not mean high-converting. Avatar reads and auto-dubs can feel stiff or slightly off, and TikTok audiences are quick to reject content that looks synthetic, so Symphony is best for speed and volume of tests, not as a replacement for footage that actually lands.

It makes ten versions in an hour. Your job is still finding the one that works.
