Postcurve: analytics for your X account

Private analytics for your own X posts: what's working, what's taking off, and when to post. Stored only in your browser.

See what's actually working on your X account. Postcurve turns the numbers X already shows you into clear, private analytics. Browse as usual; it reads your own posts' views, likes, replies, reposts and bookmarks, and your follower count, and builds your history in your browser. What you get A dashboard with your impressions, engagement and followers over any period, and how they changed. Every post compared fairly: against your own similar posts at the same age, so a 2-hour-old post isn't judged against week-old ones. A side panel beside X: open one of your posts and see how it compares with your typical post at the same age, its rank and early speed, plus your live posts, your numbers and your best time to post. A live badge when a recent post is taking off. Which topics, hooks, formats and posting times have done best for you, each with how many posts it's based on and how reliable it is. Weekly, monthly and yearly reports, and share cards you can post in a click (nothing is posted until you press Post yourself). Import your X archive or analytics export to fill in older history. Export everything as CSV or JSON, anytime. Private by design Your data stays in this browser. There is no account to create and no server. Only your own posts and profile are read. Other people's posts aren't stored. It never posts, likes, follows or changes anything on your account. Delete all data in one click from Settings.
