About this launch
ReplyKit is a Chrome extension and web app that helps users grow on social media by identifying high-value posts worth replying to and generating three draft replies in each user's own voice. The tool works on X, LinkedIn, and Reddit, using Claude Sonnet AI model to create contextual, personalized responses. Users always decide which draft to post or whether to edit before publishing—ReplyKit never posts automatically. The Opportunity Radar feature scores posts based on topic relevance, author audience size, and reply timing. ReplyKit runs on Claude Sonnet on every plan including the free tier, requires no API key configuration, and never asks for password access.

Shopper questions
Does ReplyKit post for me?
No, ReplyKit only writes draft suggestions. You pick a draft, can edit it if you want, and press post yourself. It never posts, likes, follows or messages on your behalf, and never asks for your password.
Do I need an API key?
No. Generation runs through ReplyKit's own service on Claude Sonnet, available on every plan including free. There is nothing to configure.
Which browsers and platforms does ReplyKit support?
ReplyKit works on Chrome and other Chromium browsers like Edge, Brave, and Arc on desktop for X, LinkedIn, and Reddit. Opportunity Radar works on X. On a phone, use the web app: paste a post, get a draft, and copy it back.
