Overview

Better Japanese Captions reflows Japanese subtitle lines on YouTube so they break at more natural places—easier to read at a glance.

How it works:
• Runs only on youtube.com pages (desktop and mobile domains declared in the manifest).
• Uses Budoux-style segmentation bundled inside the extension—no caption text is sent to a developer-operated server.
• Includes an on-player toggle to restore YouTube’s original caption layout when you want to compare.

Privacy:
• No accounts, no analytics SDKs, no remote caption uploads by this extension.
• See the Privacy Policy linked from the listing for details.

YouTube の日本語字幕が、読みやすい位置で改行されるようにレイアウトを調整します。処理はすべてブラウザ内で行われます。

• 対象サイトはマニフェストで指定した YouTube(youtube.com/www/m のみ)。
• Budoux に相当するモデルを同梱しローカルで分割。開発者運用サーバーへの字幕送信はありません。
• プレーヤー横のトグルで、本来の字幕レイアウトに戻して比較できます。
• アカウント不要・アプリ内解析・字幕データの開発者側収集なし。
