ToneBird

ToneBird is an AI reply assistant for Mac and Windows that helps you figure out what to say without starting every message from scratch. It can use your previous conversations, relationship context, and connected files to draft replies in your own style, with support for over 6 different apps including Gmail and Slack. To use it, install ToneBird, connect the apps or information you want it to reference, then review and edit its suggested response before sending. The tool offers a free plan with up to 15 drafts per day.
