SENTENCE COUNTER — Real-Time Text Statistics for Writers & Editors A sentence counter is one of the most useful tools a writer can have. Whether you are editing an email, polishing a blog post, checking SEO copy, or trimming a social media caption, knowing your exact sentence count, word count, and reading time in real time lets you work faster and with more confidence. This extension gives you an instant sentence counter right inside your Chrome browser — always available, always offline. WHY THIS SENTENCE COUNTER IS DIFFERENT Most online word and sentence counter tools open in a separate tab, require you to paste text, click a button, and navigate back to your work. This sentence counter updates every statistic as you type, with no button to click and no page to reload. It is the sentence counter that gets out of your way and just works. Writers who move frequently between their writing environment and a sentence counter lose their flow. This extension solves that by placing the sentence counter one click away in the Chrome toolbar. Open it, paste or type your text, and all six metrics update instantly. KEY FEATURES 📝 Sentence Counter — The core feature. The extension counts sentences in real time using punctuation detection (.!?), so you always know exactly how many sentences your text contains. 🔤 Word Counter — Counts total words by splitting on whitespace. The word count updates on every keystroke alongside the sentence count. 🔡 Character Counter — Displays total character count including spaces. Essential for platform-specific limits like Twitter, LinkedIn bios, and SMS. 🚫 Characters Without Spaces — Shows the character count excluding spaces. Useful for density analysis and comparing against character-based limits. ¶ Paragraph Counter — Detects paragraphs separated by blank lines and counts them alongside the other metrics. ⏱️ Reading Time — Calculates estimated reading time at 200 words per minute. Always shows a minimum of 1 minute so you never see a misleading zero. 🗑️ One-Click Clear — The Clear button wipes the input and resets all counters to zero instantly. 🌍 33 Languages Supported — The sentence counter interface is localized for 33 languages including English, Russian, German, French, Spanish, Italian, Portuguese, Dutch, Japanese, Korean, Chinese, Arabic, and more. 🔒 Fully Offline and Private — This sentence counter requires no permissions, connects to no servers, and stores no user data. All calculations happen locally. HOW TO USE 1. Click the sentence counter icon in your Chrome toolbar. 2. Paste or type your text into the text area. 3. Watch the sentence counter and all five other metrics update in real time. 4. Use the Clear button to start fresh with a new piece of text. The sentence counter is ideal for continuous use — keep the popup open while writing and check your metrics as often as you need without switching contexts. USE CASES Writers checking essay structure use the sentence counter to ensure paragraph variety. Email marketers verify subject lines and body copy meet length guidelines. SEO professionals check word counts and hit target densities. Students confirm they have met assignment minimums. Social media managers verify copy stays within platform character limits. Editors spot overly long or short paragraphs quickly. ACCURACY The sentence counter detects sentences ending in periods, exclamation marks, and question marks. It correctly handles text that contains no sentence-ending punctuation by counting the entire block as one sentence. Word counting splits on any whitespace, so multiple spaces, tabs, and line breaks are handled cleanly. Reading time uses the widely accepted 200 words per minute reading speed used by most productivity tools. PRIVACY This sentence counter extension requires no permissions. It does not access any open tabs, does not read any web page, does not connect to the internet, and does not store any text you enter. The popup is a fully isolated, self-contained environment. The text you type into the sentence counter never leaves your browser. Upgrade your writing workflow today with a sentence counter that gives you instant feedback, everywhere, every time.
