About the Lab

We partner with clients on films and digital experiences, develop original products, and research how AI can expand what we create.

NLINEA is a Creative AI Lab, part of The Unbound Company. We take client briefs from creative direction through film, design and digital delivery. Alongside commissioned work, we build our own products and investigate AI workflows through prototypes, testing and development.

Two languages. One subtitle.

Prepare bilingual subtitles for the player you already use. SubDuet pairs two language tracks into a portable file alongside your video.

Preparation stays separate from playback.

Choose your language pair, save the bilingual file, then open it in your usual player.

Try the public beta.

Public beta v0.1.0b15 is available for macOS, Windows and Linux. Desktop packages are unsigned; review the official release notes before installing.

FFmpeg is required for media extraction and speech workflows. Optional external services have their own terms and costs.
