版本 0.10.0最新
- 改进New name and logo: FastSub AI. Same promise: 100% on your device.
- 新增Vocal remover: split any song or video into vocals and a karaoke instrumental, with an AI model running in your browser.
- 改进Long recordings use about 30% less memory: audio is decoded straight into one buffer that the AI workers share instead of copying.
- 新增Translate many subtitle files at once and download them as one ZIP.
版本 0.9.0
- 改进Subtitle translation works on whole sentences, then splits them back over the original lines: far fewer broken or garbled fragments.
- 新增Auto-sync can now match the spoken words to the subtitle text: accurate even with music, explosions or cut scenes (subtitles in the spoken language).
- 新增Dual subtitles: combine two languages into one file, as two lines per subtitle or top and bottom (.ass).
- 新增Works offline: pages and tools you have opened keep working without a connection.
- 修复Link previews (Open Graph images) no longer cut off text and now show Japanese, Chinese, Korean, Thai, Hindi and Arabic correctly.
- 修复Exported videos (dubbing, noise removal) no longer have audio 44 ms behind the picture.
- 修复Cancel now really stops AI jobs, including when pressed before a step starts; auto-sync got a Cancel button.
- 改进Screen readers announce progress on every tool, and editor line buttons have clear labels.
版本 0.8.0
- 改进Transcription no longer invents text over music, noise or silence: a voice detector picks the parts with speech and repeated loops are removed.
- 新增Names and terms field: list people, brands or jargon and the AI spells them correctly.

- 新增Remove background noise from recordings and videos (fans, traffic, wind, keyboard), with before/after preview.
- 新增New look based on Google Material Design 3 (Google blue, Roboto, standard components), a wider layout for large screens, and dark mode that follows your system setting.

- 新增Support the project page: give by card, PayPal, Buy Me a Coffee, Ko-fi, crypto (with QR codes) or bank transfer, plus other ways to help. Help and the ticket form now live on the contact page.
