Arion AstraFoundry

Arion is voice input that stays on your computer. Dictate into any app on macOS or Windows: Arion recognizes Chinese, English and both mixed on your device, works offline, and is open source under AGPL-3.0. Press the shortcut in any app and speak Chinese, English or both. Arion recognizes your speech on the device and types the text where your cursor is. Switch between Chinese and English mid-sentence, the way people talk about code and meetings; you never pick a language first. While you speak, the text stays a draft in the pill and only the finished sentence is typed. Speech recognition runs on your device. After the one-time model download, dictation needs no network, and no audio or text is sent anywhere. Audio stays in memory only for the current dictation, is never written to disk, and is never sent. The vocabulary is encrypted with AES-256-GCM and its key is kept in the Keychain or DPAPI. Correct a word Arion typed and it applies the fix next time, with an undo. Learned words stay on the device, encrypted. The bundled Pinyin keyboard works offline with local candidate ranking and vocabulary, and Shift switches between Chinese and English. Polishing and translation are off until you enable them and choose a provider and model. Clipboard history is off until you turn it on, and it is encrypted on this computer.
