What we are building

AI Dubbing Checker is an independent project for creators, educators, and localization reviewers who want a practical checkpoint before publishing a dubbed video. We focus on evidence that a reviewer can inspect, rather than a single unexplained quality score.

What you can use today

The free browser tool compares timestamped transcripts for numeric consistency. It supports English, Spanish, and German number formats and a defined set of explicit units. It can flag a repeated number that changes in a later passage, accept supported measurement conversions, and export a timestamped JSON review list.

What needs a human ear

A transcript mismatch does not prove an audio error. The current tool does not evaluate translation meaning, pronunciation, voice similarity, emotion, or lip synchronization. Listen to the source and dubbed tracks before making a publishing decision. We do not claim a production accuracy rate.

How we handle your material

Transcript parsing and checks happen locally in your browser. Your transcripts and reports are not uploaded by the checker. We use aggregate usage counts to understand whether the tool works, with controls explained in our Privacy notice.
