Overview
SuperX is an all-in-one audience growth platform designed specifically for X (formerly Twitter) creators. Built by indie makers Tibo and Rob, it combines real-time analytics, AI-powered content creation, and smart scheduling into a unified growth engine. Unlike multi-platform AI social media post generators, SuperX focuses exclusively on X, delivering deep insights and actionable data that help creators understand their audience, refine their content strategy, and accelerate growth.
The platform serves creators who take X seriously—indie hackers building in public, content creators publishing daily, founders turning followers into early adopters, and influencers staying relevant without burnout. According to the official website, SuperX is "Loved by 1,458+ creators" and has helped over 5,000+ creators grow their X presence. It's positioned as a lightweight yet comprehensive alternative to tools like TweetHunter and Hypefury.
SuperX is available as both a Chrome extension (featured on the Chrome Web Store with 10,000+ users) and a web application at app.superx.so. The extension focuses on in-feed analytics with instant sidebar insights while browsing X, while the web app provides a centralized workspace for content creation, scheduling, and performance management.
Key Features
AI Chat Mode with Voice Learning — Creates content that matches your unique writing style by learning your tone, helping you write tweets that sound authentically you, not robotic. Includes built-in web search and content integration for research-backed posts, similar to advanced AI chatbots.
Algorithm Simulator — Predicts engagement before you hit publish by simulating how thousands of users and X's ranking algorithm will react to your post, allowing you to A/B test variations and optimize for maximum reach.
Advanced Inspiration Engine — Surfaces trending topics and high-performing posts in your niche with semantic search and fresh filters, so you can spot viral patterns and engage with hot conversations while they're still active.
Next-Gen Scheduler with Smart Timing — Learns when your followers are most active and automatically schedules posts at optimal times, featuring auto-retweet for second-wave visibility, auto-plug to insert CTAs when engagement thresholds are hit, and auto-delete to keep your timeline clean.
Real-Time Analytics Dashboard — Tracks performance metrics, follower growth trends, and engagement patterns with actionable reports that rank your best tweets and explain what's working, accessible both in-app and via Chrome extension overlay, making it a powerful AI productivity tool for content creators.
SuperX Library with Semantic Search — Lets you search top-performing tweets by topic and recency (as fresh as this week) using natural language queries, helping you discover relevant content worth engaging with or remixing.
