AI.opensubtitles.com is an online platform that utilizes artificial intelligence to
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.
users with a user-friendly means of extracting audio tracks from movie files and generating
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.
Our platform makes it easy for users to upload their audio, video, or subtitle files. You can
choose from various AI models and languages to generate subtitles or translate existing ones.
Behind the scenes, our advanced algorithms ensure speedy and accurate transcriptions and
translations. What makes us stand out is our use of client-side audio extraction from movies,
thanks to FFmpeg wasm. This means we can generate subtitles faster and more efficiently than
many other platforms, providing our users with a smooth and streamlined experience.
In addition to these features, our credit-based payment system adds another layer of convenience.
Users have the flexibility to purchase credits, which are then utilized when accessing AI
services. This pay-as-you-go approach ensures cost-effectiveness, allowing users to pay only for
the specific services they need. The credits never expire, providing users with the freedom to
integrate AI services seamlessly into their workflows without the pressure of expiration dates.
This unique advantage empowers our users with control, flexibility, and personalized
cost-efficiency in their interactions with our platform.
AI.opensubtitles.com supports a wide range of languages. Users can select the
transcription based on their preferences.

The platform continually tests new and upcoming AI models for translation and transcription,
providing users with a diverse selection of options in terms of both pricing and quality. Our
platform offers multiple AI models with varying levels of accuracy and features. Users can

Our pricing structure is determined by the usage of credits, which is influenced by both the
chosen AI model and the duration of the uploaded file. In the case of transcription, the
calculation is based on seconds, with each AI model having a distinct rate per second. When
dealing with subtitle files, the count is on written characters, excluding timestamps from the
* per minute
* per 1000 characters

Credits operate as a flexible and user-centric payment method, offering distinct advantages over
traditional subscriptions. Users have the ability to purchase credits, which are then utilized
when accessing AI services. The beauty of this system lies in its adaptability, allowing users
to harness AI capabilities at their own pace without being tied to monthly or yearly
subscriptions. These credits never expire, providing users with the freedom to use them whenever
The longevity of credits ensures that users can seamlessly integrate AI services into their
workflows without the pressure of expiration dates. Whether it's a short-term project or an
ongoing requirement, the credits remain valid indefinitely. This flexibility aligns with varying
user needs and eliminates the rush to utilize credits within a specific timeframe.
Furthermore, the credit-based system promotes cost-effectiveness by enabling users to pay for the
precise services they consume. Unlike fixed subscription fees, credits are spent based on the
specific AI services accessed and corresponding usage. This pay-as-you-go approach guarantees
that users only pay for the services they require, offering a personalized and economical
solution tailored to individual needs. In essence, credits empower users with control,
flexibility, and cost-efficiency when utilizing AI services.
The platform prioritizes user privacy, ensuring secure processing of files and adhering to
privacy and security measures. Subtitles generated through transcription or translation are
exclusively accessible to the user who created them.
AI.OpenSubtitles.com does not retain any login/password information; instead, it employs an
OAuth2 system to access user-related data from the site on the root domain.
