Replyburst

X/Twitter growth tool — AI-powered replies and posts in your own logged-in session.

Replyburst helps you grow on X (Twitter) by replying to the right posts — in your voice — without living in the app all day. Posting into the void rarely works when you're small. Replies do: a sharp reply under a bigger account borrows their audience and puts you in front of people who already care about your topic. Replyburst makes that a daily habit instead of a chore. HOW IT WORKS • Connect your X account in one click — no password. It uses your own logged-in browser session. • Set your voice: your niche, tone, and the accounts and topics you want to engage with. • Replyburst surfaces relevant posts and drafts a reply for each one, in your style. • Review them one by one in the Engage deck — approve, edit, or skip — or turn on hands-off automation to post on a schedule. WHY IT'S SAFE • Posts through YOUR own browser session — not the X API, not a bot server. • Human-like, randomized delays between actions. • You stay in control: nothing posts without your approval unless you opt in to automation. WHAT YOU GET • AI replies that actually sound like you — not generic "Great post!" filler. • A daily queue of relevant posts, pre-drafted and ready to review. • A full history of everything posted, queued, and skipped. Replyburst is for founders, indie hackers, creators, coaches, ghostwriters, and anyone who wants to grow on X consistently without burning hours in the reply guy trenches. A free Replyburst account is required to use the extension. See our Privacy Policy and Terms at https://replyburst.io.
