What is the first thing you do when a brief lands with a word count attached to it? You write, and then you wonder, and then you paste the draft somewhere to find out. AI Word Counter is that somewhere, except it also tells you the reading time, the readability and which words you have leaned on too heavily.
Short answer: AI Word Counter counts words, characters, sentences and paragraphs in text you paste, and can add reading time, keyword density and a readability score in the same run. Counting rules are configurable, so spaces and punctuation can be included or excluded.
What is AI Word Counter?
AI Word Counter is a free browser tool that measures text. Paste a draft into the box, choose what you want counted, and the result comes back with as much or as little breakdown as you asked for.
Counting sounds simple and is not, because different people count differently. Does a hyphenated term count as one word or two. Do headings count toward the total. Do you count characters with spaces or without, which is the difference between fitting a field and overflowing it. The Include control makes that choice explicit rather than leaving you to discover which convention a tool assumed.
Why Use AI Word Counter?
Because word counts are usually contractual. A brief says twelve hundred words, a submission says three thousand maximum, a client pays by the piece. Being roughly right is not the same as being right, and the last thing you want is to discover the discrepancy after submission.
The second reason is the extra metrics. Reading time tells you whether a page will be finished. Keyword density tells you whether a term has been repeated past the point of comfort. Readability tells you whether the audience you named can actually read what you wrote. All three are counting problems, and running them at the same time as the word count costs nothing extra.
What works well
- Counting rules are explicit rather than assumed.
- Reading time, density and readability come from the same paste.
- Breakdown by sentence and paragraph shows structure, not just size.
- Free, with nothing to install.
What to watch for
- Different publishers count differently, so confirm their rule before trusting a total.
- Readability scores are indicative rather than authoritative.
- Very large documents are better handled in the application that holds them.
Important Ask what counts before you count. Many briefs exclude headings, captions and references from the total, and a draft that meets the limit on one convention can miss it badly on another.
Who Should Use It?
Freelance writers paid by length. Students working to a stated limit. Editors checking a submission before it goes to layout. Marketers who need copy to fit a fixed space. Anyone writing for a channel that enforces a limit rather than suggesting one.
| Who | What they are checking | Settings that fit |
|---|---|---|
| Freelance writer | The contracted word count | Count Type Words, Output Detail Total Only |
| Student | A limit with exclusions | Count Type All, Detailed Stats |
| Content editor | Structure as well as length | Count Type All, Breakdown |
| Marketer | Whether copy fits and reads quickly | Extra Metrics set to All |
How Does AI Word Counter Work?
The tool sits on one page. The prompt box carries a short placeholder: Paste the text to count. Under it, the model row offers MSB AI, OpenAI ChatGPT, Google Gemini and Qwen among others, and the engine you pick is remembered for the rest of the session so repeat checks stay consistent. The advanced options accordion and generate button follow.
The result appears in a card with the copy control immediately to hand, which is how most people move the figures into a note or an email, and a word count sits in the card footer as it does on every tool here. Listen, reuse, download and open in full view sit alongside, a DOC, TXT and HTML export row runs beneath, and the session history panel keeps every count from the session listed below.
Step-by-Step Guide
- Confirm which counting convention applies to your piece before you start.
- Paste the text you want measured, excluding anything the brief excludes.
- Pick a model.
- Set Count Type and the Include rule to match the convention you confirmed.
- Turn on the extra metrics you actually want, rather than all of them by habit.
- Generate, and keep the run in the history if you will be checking again after edits.
Before you rely on a number:
- ✅ The counting convention matches the one the brief uses
- ✅ Headings and captions are in or out deliberately
- ✅ References and footnotes are handled according to the rule
- ✅ The Include setting matches whether spaces count
- ✅ You pasted the final draft, not the one before the last edit
Key Features
Five count types
Words, characters, sentences, paragraphs or all at once, so structure is measurable alongside length.
Reading time
Turns a number into something a reader would recognise, which is more persuasive in a brief than a word total.
Keyword frequency
Shows which terms you have repeated, including the ones you did not notice repeating.
Readability score
An indicative check on whether the writing matches the audience you had in mind.
Explicit include rules
Everything, exclude spaces, exclude punctuation or visible only, so the total means what you think it means.
Advanced Options Guide
The panel does not have to be touched, and touching it is where the tool becomes yours. Opening it is what turns a count into a diagnostic.
| Option | What it controls | When to change it | Starting point |
|---|---|---|---|
| Count Type | Words, Characters, Sentences, Paragraphs or All | All when you want structure as well as size | Words |
| Output Detail | Total Only, Breakdown or Detailed Stats | Total Only when you just need the number for a brief | Breakdown |
| Include | Everything, Exclude Spaces, Exclude Punctuation or Visible Only | Every time a character limit is involved | Everything, then switch if the limit excludes spaces |
| Extra Metrics | None, Reading Time, Keyword Density, Readability or All | Turn on only what you will act on | Reading Time |
| Count Spaces | Whether spaces count toward character totals | Match the platform's rule, which usually counts them | On |
| Show Reading Time | Adds an estimated reading duration | On for anything published rather than submitted | On |
| Keyword Frequency | Lists the most repeated terms | On when editing your own draft, which is where repetition hides | On |
| Readability Score | Adds an indicative reading level | On when writing for a named audience | On |
| Detail Level | Slider from 1 to 100 controlling how much explanation surrounds the figures | Low when you want numbers, higher when you want interpretation | Around 35 |
| Custom Instructions | Free text up to 1000 characters | State the counting convention in force | Try "exclude headings, captions and the reference list from the total" |
Tip Writing the convention into Custom Instructions rather than editing the text before pasting keeps your draft intact and makes the count reproducible next time.
Example Inputs
Input for a counter is just the text, but what you leave out matters. A typical submission check on the AI Word Counter looks like this:
[Paste the full body text here, headings included]
Custom Instructions:
Count the body text only. Exclude the title, the three
subheadings, the pull quote and the reference list at the
end. Report words with and without those exclusions so I
can see both figures.Asking for both figures in one run is the useful trick, because the difference between them is exactly the number you will be arguing about if anyone queries the total.
Pro tip Count the piece once before editing and once after. If the total barely moved but the readability improved, the edit did what a good edit should, and that is a harder thing to see by reading alone.
Comparison Table
| Where you count | Advantage | Limitation |
|---|---|---|
| AI Word Counter | Explicit rules plus readability and density in one pass | Requires pasting the text somewhere |
| Your word processor | Live count as you write | One convention, and no density or readability |
| A browser extension | Counts what is on screen | Inconsistent about hidden and duplicated content |
| Counting by hand | Complete control over what counts | Only realistic for a paragraph |
Most people use the word processor while drafting and something like this at the end, when the number stops being informational and starts being contractual. If the piece is over length, the AI Text Summarizer is the natural next stop.
AIToolsay is the catalogue you browse when the next job differs, and a word count is almost always a checkpoint rather than a destination. Text that is over length needs cutting, text that reads badly needs rewriting, text with a repeated term needs varying, and a finished piece needs a summary and a headline. Every one of those is covered by a tool, and the interface never varies between them: the same prompt box, the same model row, the same options accordion, the same export controls, the same session history panel. All of it free, all of it immediate, and all of it able to read the last result as it stands.
Frequently Asked Questions
Is AI Word Counter free?
Yes, free throughout, with nothing behind a wall.
Does it count the same way my publisher does?
Only if you tell it to. Conventions differ, so state the rule in Custom Instructions and ask for the figure both with and without the exclusions.
How accurate is the reading time?
It is an estimate based on typical reading speed. Useful for comparing two drafts, not something to quote as a precise duration.
What does keyword frequency actually help with?
Catching unintentional repetition. Most writers have three or four words they overuse without noticing, and seeing them listed is usually enough to fix it.
Should I trust the readability score?
Treat it as a signal. A score far from your target audience is worth investigating; a small difference between two drafts rarely means anything.
Can I count characters without spaces?
Yes. Set Include to Exclude Spaces or turn Count Spaces off, and check which rule the platform you are writing for actually applies.
Confirm the convention, paste the final draft, and ask for both figures. That takes one run and removes the only real risk in counting, which is measuring something slightly different from what the brief meant.
