cotabby

What it does

Shows a grey suggestion beside the cursor as you type in mail, chat, notes or anywhere else, accepted word by word with Tab. By default it uses Apple's on-device model, so what you write stays on the machine; switching to a cloud provider changes that. Marked beta and correspondingly rough. It needs permission to read text fields, which is worth thinking through before granting. Mac only.
