## What it does
SubMiner is an Electron overlay that sits on top of mpv. It turns your video player into a full sentence-mining workstation:
- **Look up words as you watch** — Yomitan dictionary popups on hover or keyboard-driven token-by-token navigation
- **One-key Anki mining** — Creates cards with sentence, audio, screenshot, and translation; optional local AnkiConnect proxy auto-enriches Yomitan cards instantly
- **Reading annotations** — N+1 targeting, frequency-dictionary highlighting, JLPT underlining, and character name dictionary for anime/manga proper nouns
- **Subtitle tools** — Download from Jimaku, sync with alass/ffsubsync
- **Jellyfin & AniList integration** — Remote playback, cast device mode, and automatic episode progress tracking
- **Texthooker & API** — Built-in texthooker page and annotated websocket feed for external clients
## Quick start
### 1. Install
**Arch Linux (AUR):**
Install [`subminer-bin`](https://aur.archlinux.org/packages/subminer-bin) from the AUR. It installs the packaged AppImage plus the `subminer` wrapper:
```bash
paru -S subminer-bin
```
Or manually:
```bash
git clone https://aur.archlinux.org/subminer-bin.git
cd subminer-bin
makepkg -si
```
**Linux (AppImage):**
```bash
wget https://github.com/ksyasuda/SubMiner/releases/latest/download/SubMiner.AppImage -O ~/.local/bin/SubMiner.AppImage
chmod +x ~/.local/bin/SubMiner.AppImage
wget https://github.com/ksyasuda/SubMiner/releases/latest/download/subminer -O ~/.local/bin/subminer
chmod +x ~/.local/bin/subminer
```
> [!NOTE]
> The `subminer` wrapper uses a [Bun](https://bun.sh) shebang. Make sure `bun` is on your `PATH`.
**macOS (DMG/ZIP):** download the latest packaged build from [GitHub Releases](https://github.com/ksyasuda/SubMiner/releases/latest) and drag `SubMiner.app` into `/Applications`.
**Windows (Installer/ZIP):** download the latest `SubMiner-.exe` installer or portable `.zip` from [GitHub Releases](https://github.com/ksyasuda/SubMiner/releases/latest). Keep `mpv` installed and available on `PATH`.
**From source** — initialize submodules first (`git submodule update --init --recursive`). Bundled Yomitan is built from the `vendor/subminer-yomitan` submodule into `build/yomitan` during `bun run build`, so source builds only need Bun for the JS toolchain. Packaged macOS and Windows installs do not require Bun. Windows installer builds go through `electron-builder`; its bundled `app-builder-lib` NSIS templates already use the third-party `WinShell` plugin for shortcut AppUserModelID assignment, and the `WinShell.dll` binary is supplied by electron-builder's cached `nsis-resources` bundle, so `bun run build:win` does not need a separate repo-local plugin install step. Full install guide: [docs.subminer.moe/installation#from-source](https://docs.subminer.moe/installation#from-source).
### 2. Launch the app once
```bash
# Linux
SubMiner.AppImage
```
On macOS, launch `SubMiner.app`. On Windows, launch `SubMiner.exe` from the Start menu or install directory.
On first launch, SubMiner:
- starts in the tray/background
- creates the default config directory and `config.jsonc`
- opens a compact setup popup
- can install the mpv plugin to the default mpv scripts location for you
- links directly to Yomitan settings so you can install dictionaries before finishing setup
### 3. Finish setup
- click `Install mpv plugin` if you want the default plugin auto-start flow
- click `Open Yomitan Settings` and install at least one dictionary
- click `Refresh status`
- click `Finish setup`
The mpv plugin step is optional. Yomitan must report at least one installed dictionary before setup can be completed.
### 4. Mine
```bash
subminer video.mkv # default plugin config auto-starts visible overlay + resumes playback when ready
subminer --start video.mkv # optional explicit overlay start when plugin auto_start=no
```
## Requirements
| Required | Optional |
| ------------------------------------------ | -------------------------------------------------- |
| `bun` (source builds, Linux `subminer`) | |
| `mpv` with IPC socket | `yt-dlp` |
| `ffmpeg` | `guessit` (better AniSkip title/episode detection) |
| `mecab` + `mecab-ipadic` | `fzf` / `rofi` |
| Linux: `hyprctl` or `xdotool` + `xwininfo` | `chafa`, `ffmpegthumbnailer` |
| macOS: Accessibility permission | |
Windows builds use native window tracking and do not require the Linux compositor helper tools.
