Cloud dictation tools are fast — but every word you speak is sent to a remote server, processed there, and returned. For personal notes, client work, or anything sensitive, that's a problem.
Lexis runs entirely on your Mac. Hold one key, speak, release — the transcribed text appears instantly wherever your cursor is. No internet required. No data leaves your device. Powered by Whisper on Apple Silicon.
