Video, cut to the sound of speech.

Synctia turns a single prompt into a fully edited video — narration, subtitles, and music locked together to the millisecond. Not by waiting for speech recognition to finish a word, but by detecting the instant it begins.

The problem

Every existing tool syncs too late.

How it's done today

Captioning and dubbing tools time text to the moment speech recognition finishes a word — after it has already been spoken. The gap is small, but it's audible and visible: a caption that lands a beat behind the mouth that formed it.

What Synctia does instead

Synctia detects the onset of the consonant — the attack — the same reference point a musician uses to lock a performance to a click track. Subtitles, cuts, and music land on the sound, not after it.

The library

Every asset is rights-cleared.

Synctia draws from a human-curated, copyright-free asset pool — the single largest cost in building the system, and the reason a creator using Synctia never faces a takedown, a demonetised upload, or a legal claim over something they didn't know they'd used.

Where we are

Status

Founder

Built by someone who heard the problem first.

Toshitaka Fujikawa

A composer and musician before a founder. Years of scoring and editing video by ear — nudging captions and cuts back onto the beat one frame at a time — led to the idea underlying Synctia: sync video the way a musician syncs a performance, off the attack, not the aftermath.
