 - `python3 scripts/seo_sync.py` rewrites the FAQPage JSON-LD on every page from the FAQ that is visible on that page, and refreshes `<lastmod>` in `sitemap.xml` from git. Run it after editing a FAQ or a page (needs `beautifulsoup4`).
 - CI (`.github/workflows/seo-check.yml`) runs `scripts/seo_sync.py --check` and fails if the markup and the visible FAQ drift apart.
-- `python3 scripts/build_zh.py` rebuilds the Chinese tool pages (volume booster, text to speech, joiner, compressor) from the English ones with the translation tables in the script, and keeps hreflang, the 中文/EN switch and the Chinese navigation in step. It stops if an English string it translates has changed, and runs `scripts/seo_sync.py` at the end.
+- `python3 scripts/build_zh.py` rebuilds the Chinese tool pages (all tools except the converter, which is maintained by hand) from the English ones with the translation tables in the script, and keeps hreflang, the 中文/EN switch and the Chinese navigation in step. It stops if an English string it translates has changed, and runs `scripts/seo_sync.py` at the end.
 - `python3 scripts/build_landing.py` rebuilds the format pages (`/mp4-to-mp3/`, `/video-to-mp3/`, `/mp3-to-wav/`, `/wav-to-mp3/` and their `/zh/` versions) from the converter pages: same code, own copy and FAQ, output format preselected via `<body data-default-format>`. Run it after changing a converter page; it also refreshes the "Popular conversions" links on the converters and runs `seo_sync.py`.
 - Social preview images live in `og/` (1200×630, one per tool).
