What is ai.OpenSubtitles.com ?

ai.opensubtitles.com is an online platform that utilizes artificial intelligence to transcribe and translate audio and video files. Users can easily convert their multimedia content into text and translate it into various languages.

In early 2023, a company approached me with the goal of automating the subtitling process for their extensive collection of software tutorial videos. They wanted to generate subtitles and translate them into multiple languages. In response, I developed a PHP backend, accessible through REST API, to automate audio track extraction and transcription using an AI model. Subsequently, I created a web front end using HTML5, Javascript, and WASM modules to provide users with a user-friendly means of extracting audio tracks from movie files and generating subtitles.

After discussions with the developer of OpenSubtitles.org, the largest public database for movie subtitles, we decided to host the platform on a subdomain. We integrated the user base from the main domain using a mechanism similar to OAuth2, allowing users of OpenSubtitles.org to log in to AI.OpenSubtitles.com with their main site credentials. At this stage, we introduced a credit-based payment system, utilizing the payment provider service from the main site.

Over the following months, I conducted extensive testing on various AI models for transcription and translation. The successful models were incorporated into the subtitle generator platform, providing users with a diverse range of choices. In July 2023, AI.OpenSubtitles.com was officially launched and has since experienced growth in both user numbers and the selection of available AI models.

As of September 2024, a new login option has been introduced. Now, in addition to logging in with their OpenSubtitles.org credentials, users can also sign in directly using their OpenSubtitles.com account.
