Postcurve - Understand what actually works on X

See what's working on your X account: every post compared with your own posts at the same age. Free, and stored only in your browser.PostCurve is a free X analytics extension that shows you what actually works on your account. It analyzes your posting history to uncover your best topics, hooks, formats, timing, breakout posts, underperformers, second waves and engagement patterns — directly inside X. No separate dashboard. No X API setup. Just install it and understand your content better.

Hey Product Hunt 👋 I built PostCurve because I post on X a lot, but I kept running into the same problem: X gives you numbers, but it doesn't really tell you what those numbers mean. A post gets 20K views. Another gets 300. Was it the topic? The hook? The format? Timing? Did it take off immediately or hours later? Was it actually good relative to the size of my account? I wanted something that could look at my own posting history and help me understand the patterns. So I built PostCurve. It works directly inside X and analyzes things like: • your strongest topics • hooks and post formats • breakout vs normal posts • underperformers • engagement patterns • posting timing • posts that get a second wave of distribution • performance relative to your own baseline There’s no separate analytics dashboard to maintain and no complicated setup. Install the extension, open X, and PostCurve starts helping you understand what your own data is telling you. I originally built it for myself while trying to get better at distribution, but I figured other founders, indie hackers and creators probably have the exact same problem. PostCurve is free right now. Would especially love feedback on one thing: **What is the one question about your X performance that existing analytics still doesn't answer for you?**
