NAS-Subtitler

NAS-Subtitler is an AI-powered subtitle generator and translator designed specifically for use on network-attached storage (NAS) systems. It enables users to generate subtitles for video files locally, emphasizing privacy by ensuring that all processing occurs on the user's own device without requiring internet access. The tool is positioned for those seeking to automate subtitle creation and translation for their media libraries, with applications in home entertainment, education, training, and content creation.

The platform supports over 50 languages, including bilingual subtitle options, and offers AI-driven translation that is described as context-aware. NAS-Subtitler can process all major video formats such as MP4, AVI, MKV, and MOV, and outputs subtitles in widely used formats including SRT, VTT, and ASS. It features batch processing capabilities, allowing users to handle multiple videos or entire seasons at once, and includes smart retry logic for automated workflows. The tool integrates seamlessly with popular media server platforms like Plex, Jellyfin, and Emby, enabling automatic detection of new videos and immediate subtitle generation for home theater setups. For educational and training scenarios, it provides workflows for quality control and team collaboration.

Deployment is streamlined through a single Docker command, making it accessible for users with compatible NAS devices that support Docker and Docker Compose. The service allows users to select their preferred AI provider, such as OpenAI, Claude, or a custom endpoint, and requires configuration of an API key through its web interface. Local speech detection ensures that audio processing remains entirely within the user's network, reinforcing its privacy-first design. Users can configure directories for their media libraries and data storage, and the system is designed for 24/7 automatic operation with minimal user intervention.

NAS-Subtitler offers flexible pricing plans, allowing users to control costs by selecting their AI provider and usage level. Balances do not expire, and a 30-day money-back guarantee is available. The platform is suitable for movie enthusiasts, educators, and content creators who require efficient, private, and automated subtitle workflows on their NAS devices.
