As answered by people managing PostSharp and CharCount.app.
CharCount.app's answer:
CharCount combines speed, privacy, and multilingual support in a single lightweight tool. All text analysis runs entirely in the browser — no text is ever uploaded to a server — and the interface is fully translated into 11 languages, not just English. There's no signup, no ads-first clutter, just instant character, word, sentence, and paragraph counting.
CharCount.app's answer:
Most character/word counters are either bloated with ads, require an account, or only support English. CharCount is built for speed (optimized for top PageSpeed scores), works instantly with no signup, keeps all processing client-side for privacy, and is usable natively in 11 languages — making it a better fit for non-English speakers and anyone who wants a fast, no-friction tool.
CharCount.app's answer:
Writers and students checking word/character limits, social media managers verifying post length for platforms like X/Twitter, SEO professionals optimizing title tags and meta descriptions, and anyone who needs a quick, reliable text count without installing software or creating an account.
CharCount.app's answer:
CharCount was built out of the need for a simple, fast, and privacy-respecting alternative to cluttered, ad-heavy character counters. Launched in 2026, it focuses on doing one thing well — accurate text counting — while being genuinely usable across languages, not just an English-first tool with translations bolted on.
CharCount.app's answer:
PHP (backend), vanilla JavaScript (no frontend framework), Bootstrap 5 for styling, and file-based caching for performance — no database dependency, built for speed and simplicity.
