From voice to text in one keystroke

01

Press Right Alt

Hold the key from any window. No app to open, nothing to switch to.

02

Speak naturally

Talk in English, Chinese, or a mix of both — at your own pace.

03

Get clean text

Punctuation and grammar are tidied up, then dropped right where your cursor is.

Why Lisper

Privacy by choice

Open source. Bring your own key and your voice and text never leave your machine — or use the hosted engine when you want zero setup. You decide.

English and Chinese, even mixed

Speak either language, or switch mid-sentence, and get text the way you meant it.

Works in every window

Editor, terminal, chat, email, browser — if you can type there, you can talk there.

Built for keyboard-heavy work

Made for developers and writers who live in their tools and think faster than they type.
