Pranan creates draft replies in your Gmail Drafts folder and in the Pranan app. You review, edit if needed, and send them yourself. Pranan does not request the gmail.send scope and never sends email for you. The relationship between you and your recipients is too important to delegate to a model that can't be held accountable.
Slack works slightly differently. If you connect Slack, Pranan can post a reply as you when you press Send on its review card. There is also an optional scheduled-reply setting, off by default, that schedules a draft as a Slack scheduled message which sends after 48 hours unless you edit or cancel it.
