## What it is
ytb2bili is a self-hosted video workflow application that automates downloading videos from YouTube, generating and translating subtitles, synthesizing voiceovers, creating AI metadata, and scheduling uploads to Bilibili. It combines a Go backend with a Next.js web console for task tracking, account linking, and manual review of the translation pipeline.

## Use cases
- automatically download YouTube videos and re-upload them to Bilibili
- generate translated subtitles for videos
- add AI-generated voiceover to translated videos
- auto-generate video titles and descriptions with an LLM
- schedule and queue batch video publishing to Bilibili
- review translated subtitles with synchronized audio/video playback
- run a local video translation pipeline with configurable steps

## When to choose
- you regularly republish YouTube content to Bilibili and want the whole pipeline automated
- you need subtitle transcription, translation, and voiceover in one self-hosted tool
- you want a web console to track, retry, and manage video processing tasks
- you prefer a Docker-deployable Go service with configurable pipeline steps

## When to avoid
- you only need a simple one-off video downloader like yt-dlp
- you need uploads to platforms other than Bilibili
- you require a fully managed cloud service rather than self-hosting
- you need a permissively licensed dependency - the repository has no explicit license
