Coii VoiceInput turns speech into text in your active window in about half a second - and never sends a byte anywhere. It runs fully on-device: no cloud, no account, 0 network requests. Hold Option+Space, talk, and text lands at your cursor with punctuation handled. Chinese, English, or both at once. Offline engines, searchable local history saved before processing, and it won't type into password fields. $19 once, 3 devices, 30-day trial, no card.
Coii Ref is a local-first reference manager for Mac. It indexes the image and video folders already on your disk — no import, no upload, no account — and gives you one search line across all of them, with filters and smart views that update themselves as tags and names change. Arrange anything on infinite canvases saved as plain JSON you can version or share. Files never move, and the index stays in sync with Finder. $19 once, 3 machines, all updates, 30-day trial.
Coii AudioNotes records your meetings — room audio and call participants on separate tracks — transcribes them in real time on your Mac's GPU, labels who spoke, and writes a summary organized around your own notes. Afterwards you can ask questions, answered from the transcript. Nothing is uploaded: no cloud, no account, no API keys, no analytics. It follows whatever language the meeting is in. macOS 13+, Apple Silicon or Intel. $19 once, up to 3 Macs, 30 days free.
