Wordcounter.net is one of the oldest and most-used word counting tools online. It works, it is fast, and millions of writers use it daily. But it is also covered in ads and the premium version locks features like keyword density and reading level analysis behind a paywall.
This comparison looks at what Wordcounter.net offers, what it costs, and how Ultimate Tools Word Counter compares for everyday writing and SEO tasks.
What Wordcounter.net offers
Wordcounter.net gives you word count, character count (with and without spaces), and an estimate of reading time. It also offers a keyword density analysis and some readability scores. The interface has a lot of ads. The premium tier ($9.99/month or $47.88/year) removes ads and unlocks additional analysis features.

Keyword density without a paywall
Keyword density (how often a specific word or phrase appears as a percentage of total words) is useful for SEO writers checking their content optimization. Wordcounter.net shows a basic keyword frequency list on the free tier and gates deeper analysis behind premium.
The Word Counter shows keyword frequency for all words in your text for free -- no premium tier.
Privacy
Wordcounter.net sends your text to their server for processing. For a blog draft this is fine. For unpublished content, client work, or anything sensitive, this creates an unnecessary copy of your text on a third-party server.
The Word Counter at Ultimate Tools runs in your browser. Your text is never sent anywhere.
Use cases where this matters most
SEO content writers -- Checking keyword density against a target percentage, combined with word count, gives a real-time content optimization loop. No paywall.
Students checking essay limits -- Paste the essay, see word count instantly. No account, no data retention.
Social media managers -- Check character count for Twitter/X (280 chars), LinkedIn posts (700 chars recommended), or ad copy limits.
Email subject line optimization -- Keep subject lines under 50 characters for better open rates. Paste and check instantly.
Where Wordcounter.net is better
Reading level / Flesch-Kincaid -- Wordcounter.net shows readability scores (Flesch Reading Ease, grade level). This is useful for educational content, legal documents, or content targeting specific audiences. Ultimate Tools does not offer readability scoring.
Larger community and integrations -- Wordcounter.net has existed longer and has more integrations and third-party mentions. If you need a tool your team already knows, this is relevant.
