What each tool does, with examples.

The Word Counter splits your text on whitespace and counts every token that contains at least one letter or digit. It updates on every keystroke, so you always know exactly where you stand against a limit — no more pasting into a document just to check a length requirement.
Example
"The quick brown fox jumps over the lazy dog."
↓
9 words — numbers like "2026" count; a lone "." does not.

The Character Counter counts everything: letters, digits, spaces, punctuation and line breaks. It's the fastest way to check whether a piece of text fits inside a hard technical limit before the platform you're posting to rejects it.
Example
"The quick brown fox jumps over the lazy dog."
↓
44 characters — including 8 spaces and the final period.
Use it for SMS length (160)meta descriptionsform field limitsdatabase columns
Identical to the standard counter, but every space, tab and line break is ignored. Many platforms — and many style guides — measure length this way, because whitespace says nothing about how much real content a string carries.
Example
"The quick brown fox jumps over the lazy dog."
↓
36 characters — the same sentence, minus its 8 spaces.
Use it for X / Twitter countinghashtags & slugsSEO title checksbio & profile limits
The Sentence Counter detects sentence boundaries by their terminal punctuation — periods, question marks, exclamation points and ellipses. Sentence count is the raw ingredient of readability: long documents with very few sentences are usually hard documents to read.
Example
"Stop. Wait, what? Exactly!"
↓
3 sentences — one per terminal mark, regardless of length.

The Paragraph Counter counts blocks of text separated by one or more blank lines. Paragraph structure is how readers visually pace themselves — a 2,000-word article with four paragraphs feels like a wall, while the same word count across twenty short blocks reads in minutes.
Example
A blog draft with seven blocks separated by blank lines…
↓
7 paragraphs — empty lines between blocks are never counted.

Divides your word count by 225 words per minute — the standard editorial baseline for silent adult reading — and returns an estimate in minutes and seconds. It's the number you see at the top of every good blog post, and it's computed the exact same way.

Uses a slower baseline of 140 words per minute — a comfortable, deliberate speaking pace — because we read far faster than we talk. If you've ever finished a "three-minute" speech in ninety seconds, this is the tool that prevents that.
Example
A 700-word keynote script…
↓
5:00 speaking time — 700 ÷ 140 wpm = 5 minutes on stage.

Divides the total number of letters by the number of words. It's a deceptively powerful readability signal: everyday English sits around 4.5 letters per word, while dense academic or legal writing climbs past 5.5. A rising average usually means your vocabulary is getting heavier than your reader needs.
Example
"The quick brown fox jumps over the lazy dog."
↓
3.9 letters / word — 35 letters ÷ 9 words. Plain and punchy.

Questions
Asked often, answered plainly.
( 02 )
How are words counted?
Any run of characters separated by whitespace counts as one word. Numbers count as words; standalone punctuation does not. Hyphenated terms like "well-known" count as one word, matching how most style guides and platforms count.
What speeds do the time calculators use?
The Reading Time Calculator uses 225 words per minute — the standard editorial baseline for silent reading. The Speaking Time Calculator uses 140 words per minute, a comfortable speaking pace. Both baselines are adjustable inside each tool.
Is the text I paste saved anywhere?
No. IrisTool has no backend and no database. All analysis runs inside your browser tab and disappears the moment you close or refresh the page. There is nothing to leak, because nothing is ever collected.
Can I use these tools offline?
Yes. Once the page has loaded, every tool on it keeps working offline, because all the logic runs locally in your browser.
