## What it is
yutto is a Python-based CLI downloader for Bilibili videos, supporting single and batch downloads of user uploads, bangumi, courses, collections, and favorites. It uses asyncio coroutines with chunked downloading, resumable transfers, and generates ASS danmaku (bullet comment) subtitle files.

## Use cases
- download bilibili videos from the command line
- batch download a bilibili video collection or favorites list
- download bangumi episodes with danmaku as ASS subtitles
- resume an interrupted video download
- pick specific video and audio quality streams when downloading

## When to choose
- you want a scriptable CLI for Bilibili content with batch and resumable downloads
- you need danmaku converted to ASS subtitle files alongside the video
- you want to select codec (AVC/HEVC/AV1) and quality streams explicitly

## When to avoid
- you need a GUI downloader
- you want to download from platforms other than Bilibili
- you need a general-purpose yt-dlp-style multi-site downloader
