Frequently asked
Kensi combines on-device speech recognition with AI-powered text correction. Unlike most alternatives, it works in any app via a global hotkey, supports multiple modes (Dictate, Rewrite, Ask, Ambient), and never sends your audio to the cloud.
Yes. Speech recognition runs entirely on-device. Audio never leaves your Mac or iPhone. If you use Cloud correction, only transcribed text is sent — never audio. The Privacy tier uses a fully on-device LLM so nothing leaves your machine at all.
The Voice tier and Privacy tier work completely offline. Speech recognition is always on-device. The Privacy tier adds on-device LLM correction via MLX, so you get full AI-powered correction with zero network dependency.
Kensi uses Apple''s on-device Speech framework for transcription, then applies AI correction to fix grammar, remove filler words, and format technical terms. The two-stage approach (transcribe then correct) produces cleaner output than raw transcription alone.
Absolutely. The Software Engineer persona includes 80+ technical term mappings. It resolves references like "at header component" to actual files in your workspace, formats code references correctly, and handles case conversions. It works in any IDE via the global hotkey.
Kensi is available on macOS 14+ (Sonoma) with Apple Silicon and iOS 18+. The Mac app runs as a menu bar app with a global hotkey. The iOS app includes a keyboard extension that works in any text field.
