About Word Counter
Last updated: May 2026
OptiPix Word Counter is a comprehensive text analysis tool that provides instant statistics as you type. Count words, characters (with and without spaces), sentences, paragraphs, lines, and syllables in real time. Get reading and speaking time estimates, Flesch Reading Ease and Flesch-Kincaid Grade Level readability scores, and top-10 keyword density analysis with stop-word filtering. Use platform presets for Twitter (280 chars), Instagram (2200), LinkedIn (3000), Meta descriptions (160), title tags (60), and SMS (160) to ensure your content fits within limits. The character limit checker turns red when you exceed the cap. You can also set a custom limit for any platform. Drop a .txt file to analyze it instantly. Copy your text to clipboard or download as a .txt file. Every calculation runs 100% in your browser - your text is never sent to any server, making this the most private word counter available online.
How It Works
The tool uses JavaScript string operations to split text by whitespace (words), punctuation (sentences), double newlines (paragraphs), and single newlines (lines). Syllables are estimated by counting vowel groups. Readability scores use the Flesch formulas based on word, sentence, and syllable counts.
Use Cases
- •Check word count for essays, articles, and blog posts
- •Ensure social media posts fit within character limits
- •Analyze readability for content marketing and SEO

How the counts are calculated
Words are tokenized with Unicode-aware boundaries rather than a naive split on spaces, so hyphenated compounds, apostrophes, and non-Latin scripts count correctly. Character counts are offered both with and without whitespace because different platforms measure differently - Twitter/X counts spaces, most essay word limits do not.
Sentence and paragraph counts use punctuation and line-break heuristics tuned for prose, and the reading-time estimate uses the widely cited 238 words-per-minute average for adult silent reading (and 150 wpm for speaking time, useful for speech rehearsal).
Everything runs in your browser tab on every keystroke. Nothing you paste - a confidential brief, an unpublished manuscript, exam content - is transmitted anywhere, which is the structural difference from cloud grammar tools that necessarily process your full text server-side.
