About WordCounter4U
WordCounter4U is a free set of writing tools that run entirely in your browser. Nothing you type is uploaded, there is no account, and every number the tools report is calculated with formulas we publish below.
What WordCounter4U is
WordCounter4U is a small suite of writing tools: a word counter with readability and keyword analysis, and a typing test with training aids. Both are free, neither needs an account, and both do all of their work inside your browser tab.
It exists because most tools in this category ask for more than they give. They want an email address before showing a word count, they paste your draft onto a server you know nothing about, or they hold basic features behind a subscription. WordCounter4U does none of those things, and the architecture is what makes that promise checkable rather than a marketing line.
Who it is for
- Students working to a word limit who need an exact count, not an estimate.
- Writers and editors checking readability, sentence length and passive voice before filing.
- Marketers and SEO practitioners looking at keyword density as a diagnostic.
- Speakers timing a talk, where the honest answer is a range rather than a number.
- Anyone learning to touch type who wants accuracy tracked as seriously as speed.
Why nothing is uploaded
Every calculation happens in JavaScript running on your own device. Your text is never sent to a server, never written to a database, and never logged, because it never leaves the page in the first place. Close the tab and it is gone.
That is also true of the parts you might assume need a server. File imports are parsed in the browser, including .docx, which is unzipped locally. Exports to PDF, DOCX and the rest are generated in the page. Even the downloadable audio is synthesised in your browser by a speech engine that loads on demand.
The numbers we use, and why
Every figure a tool reports comes from a formula. Publishing them means you can decide whether ours match your situation, and adjust for yourself when they do not.
| Measure | Assumption | Notes |
|---|---|---|
| Reading time | 200 words per minute | Silent reading of general prose. Technical material runs slower. |
| Speaking time | 130 words per minute | Presenting to an audience. Conversation is faster, at 150 to 190. |
| Writing time | 40 words per minute | Composing new prose, not transcription. |
| Words | Runs of letters, digits, apostrophes and hyphens | So “don’t” and “state-of-the-art” each count once. |
| Gross WPM | All characters typed ÷ 5 ÷ minutes | The standard five-character word. |
| Net WPM | Correct characters ÷ 5 ÷ minutes | What your speed is actually worth once errors are removed. |
| Keyword density | Occurrences ÷ total words | Common stop words are excluded so the list is informative. |
These constants are conventions, not laws. Reading speed in particular varies enormously with the reader and the material, which is why we describe the outputs as estimates and show the assumption rather than hiding it.
What it costs
Nothing, and there is no tier that unlocks more. Every feature you can see is a feature you can use. The site carries advertising slots to cover its hosting, and that is the whole business model.
How it is built
WordCounter4U is a Next.js application. The tools are plain TypeScript with no third-party analysis services, which is what allows them to run offline once the page has loaded. Page content and the typing corpus live in a database so they can be corrected quickly, but that content flows one way: out to you.
If you find a number that looks wrong, we would rather hear about it than not. The formulas above are the place to start the conversation.
