HunchKey
vs FlowIn
FlowIn and HunchKey both read context to finish your thoughts in any app. FlowIn is Mac-only, suggests inline as you type and adds reply drafts and rewrite actions. HunchKey works on Windows and Mac, steps in only when you ask, and can draw on your screen, your recent steps and the web, with a style for each kind of writing and a personal dictionary.

Where HunchKey is different
It knows more of the situation.
FlowIn reads context as you write. HunchKey reads the text around your cursor and, if you turn them on, your screen, the apps and files you just used and what you copied, searches the web for today’s facts, and spells your names and terms the way your dictionary says.
It doesn’t interrupt.
Suggestions that appear every time you pause can pull you out of a thought, and you end up reading text you never asked for. HunchKey stays quiet until you press the shortcut, so it only speaks when you want help, with up to three ways to finish.
It sounds like you, everywhere.
Set a tone and paste a few things you’ve written for work, email and personal messages, choose which apps and sites use each, and keep your names spelled right.
