As answered by people managing PostTruncate and ShellNewHandler.
PostTruncate's answer
PostTruncate is a free tool used by individual creators, freelance social media managers and marketing professionals worldwide. As a solo-built, pre-revenue product, it does not have enterprise customers yet — but it serves anyone who writes content across LinkedIn, X, Instagram, Facebook, Threads, and TikTok needs to know exactly where their post gets cut off before publishing.
PostTruncate's answer
Most character counters give you a number. PostTruncate gives you a visual preview — showing exactly where LinkedIn, X, Instagram, Facebook, Threads, and TikTok fold your post behind "…see more", live as you type. It also handles edge cases most tools ignore: SMS GSM-7 vs Unicode detection, X thread splitting, ad safe zone overlays, and invisible character detection. Everything runs client-side — no login, no data leaves your browser.
PostTruncate's answer
PostTruncate was built by Anirudha Kalita, a solo developer from Assam, India. After spending time crafting a LinkedIn post only to watch it collapse behind "…see more" at the worst possible moment, he went looking for a tool that showed fold lines visually before publishing. Finding nothing that worked the way he needed, he built one. What started as a LinkedIn fold checker grew into a full post preview simulator supporting 6 platforms, 10 languages, ad safe zones, SMS segment math, and AI tone rewriting — all free, all client-side.
PostTruncate's answer
PostTruncate is built with Astro as the core framework, with vanilla JavaScript handling all character counting, fold detection, and preview rendering client-side. No backend processing for the main tool — everything runs in the browser. The optional AI tone rewriting feature uses the Anthropic API. Available in 10 languages with built-in i18n support.
PostTruncate's answer
PostTruncate is the only free tool that combines live fold-line previews, character counting, SMS segment math, and ad safe zone checking in one browser-based workspace. No account needed, no install, no subscription. Competitors either charge for these features, require signup, or only handle one platform at a time. PostTruncate does all platforms simultaneously, free, forever.
PostTruncate's answer
Content creators, social media managers, marketers, and founders who write posts across multiple platforms daily and need to know exactly how their content renders before publishing. Also useful for developers working with SMS systems who need accurate segment math and encoding detection.
