ToolsBoxPro — Word & Character Counter

Word & character counter with Twitter/X & LinkedIn limits, reading time, sensitive-word alerts and live counting as you type.

ToolsBoxPro Counter is a fast, private word & character counter that works everywhere you write — in its popup, on any text field, and LIVE inside the X / Twitter and LinkedIn post composers. ━━━━━━━━━━━━━━━━━━━━ WHY INSTALL IT ━━━━━━━━━━━━━━━━━━━━ Most counters force you to copy your text into a website. ToolsBoxPro counts you where you already are: • A live counter appears right in the X, Twitter and LinkedIn composer as you type — no copy, no clicks. • One "From page" click pulls the text from whatever field you're writing in, on any site. • It gets right what generic counters get wrong: accurate Japanese/Chinese word counting and Twitter's REAL weighted limit (full-width characters = 2 points, so 140 Japanese characters correctly shows as 280). • It warns you about sensitive words BEFORE you publish. If you write posts, captions, emails, essays or product copy and care about length, limits and clean text — this saves you time on every single message. ━━━━━━━━━━━━━━━━━━━━ WHAT IT DOES ━━━━━━━━━━━━━━━━━━━━ COUNT INSTANTLY • Words, characters, characters without spaces, sentences, paragraphs, reading time • Correct word segmentation for Japanese & Chinese (uses the browser's Intl.Segmenter) SOCIAL MEDIA LIMITS • Twitter / X: official weighted count (CJK = 2, links = 23) • LinkedIn: 3,000-character limit LIVE ON THE PAGE (X / Twitter / LinkedIn) • A small live counter shows the Twitter score, character/word count, your custom limit and any sensitive words as you type in the composer SENSITIVE-WORD ALERTS • Built-in Profanity and Spam/scam lists (each can be turned off) • Add your own words: banned terms, competitor names, confidential keywords • Works for English (no false positives) and CJK CUSTOM LIMIT WARNING • Set a target by characters or words and get an over/under-limit warning TEXT TOOLS • UPPERCASE, lowercase, Title Case, Sentence case • Remove blank lines, remove duplicate lines, collapse spaces, trim MORE • Right-click any selected text -> "Count with ToolsBoxPro" • History of recent texts, one-click copy summary • Interface in English, German, French, Japanese and Dutch (auto-detects your browser) ━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR ━━━━━━━━━━━━━━━━━━━━ • Social media managers & creators — stay within Twitter/LinkedIn limits without guessing • Writers & students — hit word counts and estimate reading time • Multilingual & Japanese users — counts CJK text correctly, unlike most tools • Teams — flag sensitive or confidential words before anything goes public ━━━━━━━━━━━━━━━━━━━━ PRIVATE BY DESIGN ━━━━━━━━━━━━━━━━━━━━ • 100% offline.
