PostTruncate - Free social media feed simulator & smart thread splitter

Stop letting social media platforms ruin your hooks! PostTruncate is a privacy-first web utility that shows you exactly where the mobile feed cuts off your text (... more) on Instagram, Threads, LinkedIn, and X. Automatically split long drafts into perfectly formatted threads, monitor keyword overuse in real-time, and clean your raw copy with built-in social sanitisers. 100% free, runs entirely client-side via localStorage, and supports 10 languages.

Hey Product Hunt community! 👋 As content creators and copywriters, we all know the absolute frustration of writing a perfect social media post, only to hit publish and realise the platform's mobile feed cut our text in half right in the middle of a weak hook. I built PostTruncate.com to completely solve this workflow bottleneck. I wanted something incredibly fast, beautiful, and completely private—which is why the tool executes entirely inside your browser's local cache (no data ever touches an external server). Key Features: ✅ Real-time Mobile Feed Truncation Simulation (Instagram, Threads, X, LinkedIn) ✅ Smart Multi-Post Thread Splitting ✅ Real-time Keyword Overuse & Stuffing Monitoring ✅ Click-to-Clean Social Sanitizers (Emoji Strippers & Hashtag Extractors) The platform is completely free and supports 10 languages natively. I would love to get your honest feedback, feature requests, or answers to any technical questions right here in the comments! What platform layout should we add next? 🚀
