XReply

xreply.net

XReply is a Chrome extension for X (Twitter) that finds posts with high viral potential before they blow up, and gets your reply in early — so when the post takes off, your reply rides along and gets seen too. The more you reply early, the more X's algorithm starts surfacing viral posts to you first. It never posts for you: it writes a draft in your voice, you paste and send it yourself. Free to start with 50 credits, then $15 one-time for 5,000 credits, no subscription.

XLaunch

xlaunch.pro

XLaunch makes launch videos from your website. Paste your product's URL and describe the video you want: an AI agent reads your site, writes the story and narration, and builds every scene as Remotion (React) code in your brand's colours and fonts, then reviews its own renders and fixes them. Change anything by asking in plain words, preview it live, and export an MP4, in 2D or 3D. The plan and opening seconds are free. Also works as an MCP server for Claude.

XJumper

x-jumper.com

XJumper is an autonomous AI growth agent for small X (Twitter) accounts. Here's the problem: under ~3,000 followers, X's algorithm barely shows your posts. You can write great content every day and still be invisible — just posting doesn't work. What actually grows a small account is consistent daily engagement: replying to the right conversations, following the right people, and showing up before posts go viral. Nobody has time to do that by hand. XJumper does it for you.
