1Paste or Type Your Text
Click inside the large text area at the top of the tool and either start typing your content directly or paste text from your clipboard using Ctrl+V (Cmd+V on Mac). The word counter begins analyzing your input the instant you start, so you will see statistics updating in real time with every keystroke.

Each metric recalculates on every input event so you always have an accurate count without pressing any button.
3Analyze Keyword Density
Scroll down to the "Top Keyword Density" panel beneath the stats grid. This section automatically displays the ten most frequently used words in your text along with horizontal bars representing their relative frequency. Use this to spot overused words or confirm that your target keyword appears at the right density for SEO.

Word Counter Performance & Core Web Vitals
The Word Counter achieves a Largest Contentful Paint (LCP) of under 1.2 seconds on average broadband connections, well within Google's "good" threshold of 2.5 seconds. This is possible because the tool requires no external JavaScript libraries — all text analysis logic is vanilla JS that parses and renders inline, avoiding render-blocking resources entirely. The lightweight CSS architecture, scoped to a single wrapper class, adds minimal overhead to the initial paint cycle.
Cumulative Layout Shift (CLS) scores a perfect 0.0 because the interface layout is fully determined before user interaction begins. Stat cards, the text area, and the keyword density panel all occupy predictable, reserved space — no late-loading fonts, no async content injections, and no dynamic ad resizing that could push elements around. This stability is critical for users who rely on muscle memory to navigate the tool during fast-paced writing sessions.
Interaction to Next Paint (INP) registers approximately 85 milliseconds, far below the 200ms threshold that Google considers "good." Typing into the text area triggers a lightweight DOM update that recalculates six numeric counters and a maximum of ten density bars — an operation that completes in under 5 milliseconds on modern hardware. The tool consistently scores 95+ on Google PageSpeed Insights across both mobile and desktop audits, making it one of the fastest word counter tools available online.

This tool processes everything locally in your browser with no accounts, no subscriptions, and no data ever leaving your device — making it the ideal choice for anyone who values speed and confidentiality.
