AI writes every word you say. Then each word pops on screen and flips the colours of the video behind it: white over dark, dark over light.

Each word is drawn in "difference" mode, so it flips the colours underneath it. Over a dark background the word looks white; over a bright wall it turns dark. It's the caption style used in a lot of motivational and luxury edits.
Studio uses Whisper large-v3, one of the most accurate speech models available. Clear speech usually comes out nearly word-perfect. Loud music, strong accents or mumbling lower accuracy, so check the caption list before you render. If Studio is busy, the app switches to on-device AI by itself, which is private but makes more mistakes.
Yes. Under “Captions from”, pick Song lyrics and paste the lyrics. The AI listens to the song and times each word to when it's sung, so the spelling is always right. Lines that aren't in your clip are left out. If the vocals are heavily chopped or effected, the lyrics are spread over the song instead and you can nudge any caption into place.
Your video never leaves your device. On-device AI uploads nothing at all. Studio sends only the audio to our speech provider to write the captions, and we don't store it.
Yes. During early access every feature is free: all styles and animations, up to 4K export, SRT captions and no watermark. Studio AI includes 20 transcriptions a day, and on-device AI is unlimited. No card needed.
