Cinematic captions,
synced to every beat
of your song.
CadenceAlpha listens to your music — stems, syllables, structure — and designs broadcast-quality subtitles that move with your track. You keep the file. It plays everywhere — even natively on YouTube.
What is CadenceAlpha?
An AI caption studio built for music. Two agents do the heavy lifting — you keep full creative control.
Hears the music, not just the words
The Audio Agent separates vocal stems and force-aligns your real lyrics to the voice, syllable by syllable. No transcription guesswork.
Designs like your artist
The Design Agent studies the artist's identity, palette and era — and proposes type, color and motion that belong to the song.
A real editor, not a black box
Move words, add chromatic aberration, glitch, beat-synced pops and glows — with a live preview rendered exactly like the export.
Publish it on YouTube — for real
Export .YTT and upload it as your video's captions: colors, positions and syllable-timed karaoke render natively on YouTube. No re-rendering, no burned-in video. Plus .ASS/.SRT for VLC, OBS, DaVinci and any pipeline.
Not just music — YouTube videos too
Vlogs, tutorials, interviews: upload your YouTube video and CadenceAlpha captions it BY CONTEXT — clean and discreet, never stealing attention. A video-aware agent keeps one coherent style and highlights only what matters, and exports .YTT ready for YouTube.
How it works
From raw track to baked caption file in minutes.
Upload your track
Drop your song and its real lyrics. A music video for visual reference is optional — we'll match its grading.
Agents sync & design
Stems, syllable alignment, song structure, artist palette. What takes an editor days happens in minutes.
Fine-tune & export
Adjust word by word in the editor, preview in real time, then export .YTT for YouTube or .ASS/.SRT for everything else.
