Replies everywhere vs tasks anywhere
MaxAI is at its best in comment boxes and message fields across the social web. Hark does not try to cover every network; it concentrates on email, where replies carry tasks and dates, and on websites where something needs to be done rather than said.
From “what should I say” to “what should I do”
A reply suggestion answers the first question. Hark’s email actions also answer the second — what does this email need from me, and by when? — and can save the answer to your Tracker.
