Auto Subtitles by Eyevinn

Broadcasters and developers wanting an auditable open-source Whisper pipeline

Auto Subtitles is a smaller open-source Whisper wrapper from Eyevinn, a Swedish video-tech firm. Less feature-rich than Subsai, but the code is cleaner and maintenance comes from a known vendor — useful for organisations that need an auditable dependency in a build pipeline. CLI only, no GUI.

Auto Subtitles is an open-source Whisper-based subtitle generator maintained by Eyevinn, a Swedish video technology firm. It is more focused than Subsai, exposing a clean command-line interface for transcribing audio or video files into SubRip or WebVTT subtitles using Whisper under the hood. The audience is developers and integrators who want a single dependency to drop into a build pipeline, not end users looking for a GUI. The benefit of a known maintainer is predictability. Eyevinn ships across multiple video and broadcast tools, and the maintenance pace, code style, and licensing match what a broadcaster or software vendor expects from an auditable dependency. Subsai has more features and a GUI, but its maintenance is more community-driven, which some organisations consider a liability. Auto Subtitles is not a styling tool — there is no template library, no burn-in, no animated highlights. Output is plain SubRip or WebVTT, which integrates cleanly with downstream tools that handle styling and broadcast format conversion. Setup expects technical comfort with command-line tools and Python environments. For broadcasters and integrators producing captions through a build pipeline rather than a UI, Auto Subtitles is a defensible pick alongside or instead of Subsai. If you need a GUI or non-developer access, Subsai is the better fit; if you need clean code in a CI pipeline, Auto Subtitles wins.
