ReplyKit

ReplyKit helps users identify which posts on X (formerly Twitter), LinkedIn, and Reddit are worth replying to by scoring posts based on relevance, audience size, and recency. It then drafts three short replies in the user’s voice for each post. Users select, edit if desired, and post the replies themselves; ReplyKit never posts automatically. It runs on Chrome and compatible Chromium browsers via an extension and offers a web app version for mobile.
