Typeless and Wispr Flow upload your voice to the cloud for recognition, require you to sign in, and charge $144 a year for Pro; the upside is that they also run on Windows and phones.
Lerro uses Apple's on-device speech recognition, which arrived in macOS 26, and the app is built only for Apple silicon (M1 or later). Recognizing speech on your Mac means your voice never has to be uploaded.
Almost anywhere you can type: WeChat, Feishu, DingTalk, WeCom, Mail, Notes, Word, your browser, ChatGPT and more. It types wherever your cursor is.
Mandarin with a light accent is fine, and mixing Chinese and English works too. If a name or term you use often comes out wrong, Lerro remembers it after the AI corrects it twice.
Only Mac for now. It needs macOS 26 and Apple silicon (an M1 or later Mac).
Speech is recognized only on your Mac. With AI cleanup on, only the recognized text is sent to your own DeepSeek account. With it off, nothing is processed over the network.
