Loom for your browser
Dual-language subtitles with per-token romanization and annotation — furigana, Pinyin, Zhuyin, Jyutping, Korean Revised Romanization, and a secondary phonetic line for every supported script — rendered live over YouTube, Netflix, iQIYI, and WeTV. Activate it per tab; nothing runs until you click.

The first supported browser — Loom is built and tested on Firefox.
Loom only sends subtitle text out of your browser, for romanization — see the privacy policy for exactly what is and isn’t transmitted. Prefer working with video files directly? Use the web application.
