Blowhorn

Blowhorn is the Chrome companion for the Blowhorn Mac app. You write the post and pick the moment. Blowhorn publishes, replies and amplifies inside the Chrome profile you already use, signed in as you. Same you, faster hands. One queue, every Mac Install Blowhorn on as many Macs as you like. They all work from one shared queue, coordinated so the same post isn't sent from two Macs, and whichever Mac is awake keeps the schedule. Pause one action, one Mac or the whole fleet with a single command, and resume just as easily. A fleet behind every announcement Ship a launch post on LinkedIn and every profile you run can repost and comment while it's still fresh. Your team can get the heads-up in Slack at the same moment. Careful by design Blowhorn types and clicks at a human pace, keeps your follows on X under a daily cap, and hands every CAPTCHA and 2FA prompt straight back to you. Each profile runs one automation per platform at a time, the way you'd never type into two windows at once. Built for where builders talk Submit a launch to Hacker News and answer the thread from the same queue. Reply on Reddit while the discussion is still warm. Follow and react to the people building alongside you on GitHub. Your Macs do the work Every action runs on your own Mac, in your browser or, for platforms like Bluesky, through the platform's own API. Your account keeps the queue and one complete picture of your results in sync, and your browser sessions stay in Chrome. Hand it to your AI agent Every command explains itself with --help and rehearses with --dry-run, so an agent can drive and nothing goes out until you say so. Requirements macOS 13 or newer, Google Chrome and the Blowhorn Mac app from blowhorn.ai. Pricing Free during early access. Getting started: install the Mac app, map each Blowhorn profile to a Chrome profile, add this extension, and get back to work. Blowhorn takes it from there.
