I’ve spent a long time growing on X by replying to people every day. It worked, but opening a blank reply box over and over was slow, and generic AI replies never sounded like me. So I built Replyfast for my own workflow. Choose a tone, get three starting points, then make the final reply yours. I’m launching it on Product Hunt to learn how other builders and founders use it. If you try it, I’d love to hear what feels useful and what should improve. As a launch bonus, the first 50 Scale buyers receive a 1-year Mobbin Team membership with up to 10 seats.
