我最近发现，创业者刷短视频学东西是常事，但10分钟视频要全看完，真没那么多时间。所以想找能快速抓核心的工具——毕竟30秒get重点，比自己抠20 分钟效率高太多。 我选了三款主流工具测：听脑AI、LectMate、飞书文档。测试素材是三类短视频：10分钟创业干货（讲流量增长）、8分钟行业报告解读、12分钟产品方法 论，每款工具各测5条。比的就是转写准不准、总结快不快、结构清不清，还有长期用值不值。 先讲功能测评，核心就四个点：转写、分析、生成文档、分享。 再比性能，数据说话更直观： 转写准确率：听脑AI98.2%，LectMate92%，飞书95%； 处理耗时：10分钟视频，听脑AI28秒，LectMate1分12秒，飞书45秒； 语言支持：听脑AI7种国家语言+19种方言，LectMate只有普通话+2种方言，飞书只支持普通话； 存储容量：听脑AI免费版10G，付费版无限；LectMate免费版2G，付费版5G；飞书跟着飞书空间走，一般5G免费。 比如测12分钟的四川话"用户留存"视频，听脑AI把"留存率8%"转对了；LectMate写成"80%"，直接差十倍；飞书更绝，根本没转出来，提示"方言无法识 别" ...
