# Plint > Plint turns craft into code: automated subtitling, audio description and SDH > built on understanding, powered by Strata and designed to scale across every > title. Plint is a localisation company founded in Gothenburg, Sweden in 2002. It builds technology for subtitling, audio description (AD) and subtitles for the deaf and hard of hearing (SDH), for studios and streaming platforms. Its products run on Strata, a semantic layer that builds a structured representation of a title before localisation begins, so that language, sound and sight are worked from one foundation rather than three. ## Pages - [Home](https://plint.com/): what Plint does and why understanding comes before output. - [Products](https://plint.com/products/): the suite.
