再点火 (Saitenka) — learn Japanese from the video you're already watching

Saitenka turns mpv into an immersion workstation: Japanese subtitles get FSRS-aware word coloring, hovering a word opens a Yomitan-style multi-dictionary tooltip, and one key mines the sentence — audio, screenshot, reading, pitch, frequency — straight into Anki. Everything is drawn into mpv's own video surface, so there's no second window and none of the Windows overlay/fullscreen breakage that plagues external overlays.

Saitenka's in-mpv overlay: the word 読む highlighted in a subtitle line with its multi-definition Yomitan-style tooltip open beside it.

  • 再点火 = "re-ignition" — built to make picking study back up frictionless after a long break.
  • Local-first and grounded: readings and pitch always come from dictionaries, never a language model.

What it does

  • FSRS-aware subtitle coloring — an optional copy of Anki's database distinguishes learning, young, mature-known, and forgotten words (so "known" means actually remembered right now), and N+1 sentences — exactly one unknown word, the ideal thing to mine — are highlighted.
  • Multi-dictionary tooltip on hover — ordered definitions, ruby, frequency pills, pitch-accent, clickable cross-references, in-tooltip word scanning, wildcard search. Imports your Yomitan dictionaries.
  • One-key + bulk Anki mining via AnkiConnect — sentence audio, clean screenshot, reading, glossary, frequency, with dedup and FSRS-aware tagging.
  • No second window — the tooltip, colored subs, and mining UI composite into mpv's OSD over JSON-IPC: one surface, airspace-safe, fullscreen-safe, cross-platform (Linux · macOS · Windows).

Install

The recommended install is the self-bootstrapping release bundle (it also sets up mpv + ffmpeg and the auto-start mpv plugin) — see the Quick start.

For a pip/uv-native install of just the Python package:

uv tool install saitenka          # or: pipx install saitenka
saitenka setup                    # installs mpv/ffmpeg + the auto-start plugin, writes config
saitenka run video.mkv            # hover a word → tooltip; Ctrl+m → mine

The optional inflection-chain display is a GPL-3.0 add-on (derived from Yomitan); the core is Apache-2.0. A [full] install is therefore GPL-3.0 — see LICENSING.md.
