Show HN: Turn Your NAS into an AI Subtitle Machine (Open Source, Local)

I built an open-source tool that turns any NAS into a fully automated subtitle-generation pipeline — running completely locally, no cloud services, no data leaving your network. If you keep movies/TV shows on a Synology/QNAP/TrueNAS box, this project makes the NAS generate subtitles automatically using on-device models. Highlights Local speech-to-text with Whisper-compatible engines No external API calls — privacy by design Simple plug-and-play: drop media in a folder → subtitles appear Multi-thread + GPU acceleration support Auto-language detection, timestamp correction, subtitle formatting Web UI for queue monitoring & batch processing Works on Synology, QNAP, Unraid, TrueNAS, Docker everywhere Why I built this Existing subtitle tools either rely on cloud APIs (privacy concern), require manual processing, or don’t integrate well with NAS workflows. So this project aims to provide: A fully autonomous subtitle engine for home servers.
