Voice input that never leaves your computer

Press ⌥ Space in any app and speak Chinese, English or both. Arion recognizes your speech on the device and types the text where your cursor is.

Built for the way you talk at work

  • Works offline

    Speech recognition runs on your device. After the one-time model download, dictation needs no network, and no audio or text is sent anywhere.

  • Two languages in one sentence

    Switch between Chinese and English mid-sentence, the way people talk about code and meetings. You never pick a language first.

  • Learns from your fixes

    Correct a word Arion typed and it applies the fix next time, with an undo. Learned words stay on the device, encrypted.

Download Arion

Builds for macOS 13 or later and an early Windows preview are published on GitHub Releases.

Open source and self-hosting

Arion is open source under AGPL-3.0 and works without an account. When encrypted sync arrives, you can run the sync relay on your own server instead of ours.

Hosted sync

Encrypted sync between your devices is in development. Join the waitlist for the hosted relay, and we will email you when your access is ready. The relay only ever stores ciphertext.
