ReplyKit
Grow on X by replying to the right posts
ReplyKit finds the X posts worth replying to, then drafts three short replies that answer what the post actually says. Claude Sonnet on every plan, free included. Also works on LinkedIn and Reddit. Never posts for you.
Replies are how a small X account grows, but only if you reply to the right posts early. I was wasting evenings scrolling for those posts, then writing replies that still sounded like AI. So I built ReplyKit.
Opportunity Radar: as you scroll X, it badges the posts worth answering right now. They're in your niche, from accounts with real reach, gaining traction, and the replies are still thin, so yours gets seen. Click a badge and the reply opens with drafts already in it.
The drafts: ReplyKit reads the post and the thread above it and gives you 3 short replies in your voice. It can learn that voice from your own X posts. No "great point!", no em dashes, and always in the post's language. You pick one, edit it, post it yourself. Nothing is posted for you.
Free to start, no API key. Radar badges are free. Pro adds the ranked Radar list and target accounts.

ReplyKit was hunted by Frederic Legrand. 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.

Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
