Overview
为 YouTube、B站及主流社交媒体视频生成本地或 BYOK 云端 AI 字幕,并提供双语翻译。
LocalSub 面向没有字幕、字幕质量不佳或需要双语字幕的网页视频。 - 平台有字幕时,先取得平台字幕,统一优化断句后由用户决定是否翻译; - 平台字幕不理想时,可明确改用本地 Whisper 或 Groq Whisper Large V3/Turbo 重新识别; - 原文识别与翻译分成两步,先检查原文质量,再决定是否翻译; - 支持 Chrome 本地免 Key 翻译,也支持用户自己的主流 AI Provider API Key; - 原文轨和译文轨均保留历史版本,可切换、固定、删除和导出; - 字幕跟随播放、跳转和倍速,并为 YouTube、B站和社交媒体分别保存样式; - 长任务在 Windows 本地伴随程序中运行,关闭 Popup 后仍可继续,完成时可发送通知。 LocalSub 不要求购买会员,也不运营接收用户视频或字幕的中转服务器。选择云端识别或翻译时,数据会直接发送给用户主动选择的第三方 Provider;本地模式不会上传音频。
