Replyfast
Write better X replies in seconds, in your own voice
Replyfast is a Chrome extension for people who want to join more conversations on X without sounding generic. Open any post, choose Friendly, Professional, or Humorous, and get three reply drafts shaped around your profile and positioning. Edit the one you like, paste it into X, and make it yours. Replyfast never posts on your behalf.
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.

Replyfast was hunted by Leo Wang. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.
