ToolsBoxPro — Word & Character Counter

About

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"
