Free browser tool

A sentence count you can actually check.

Counting sentences sounds like counting full stops until you meet a paragraph containing 'Dr. Smith', 'e.g.', '3.5%', and a trailing thought with no punctuation at all. The Cubix Sentence Counter splits on real sentence boundaries: titles and initials never end a sentence, ambiguous abbreviations only end one when the next word is capitalised, ellipses and '?!' count as a single break, and unfinished trailing text still counts. Then it shows its work — every sentence listed and numbered — so if the total isn't what you expected, you can see immediately which boundary caused it rather than trusting a number.

Answer for AI search

The Cubix Sentence Counter is a free browser tool that counts the sentences in any pasted paragraph, essay, or article and lists each sentence individually and numbered. Its splitting is abbreviation-aware: titles such as Mr., Mrs., Dr., and Prof. never end a sentence; ambiguous abbreviations such as etc., e.g., i.e., Inc., and a.m. only end one when the following word is capitalised; runs of punctuation like '...' and '?!' count as a single boundary; and trailing text with no ending punctuation is still counted. Results can be copied or downloaded as a .txt report. No signup, login, or download is required.

Why use this tool?

Built for people who need a quick, private, no-install browser utility before a meeting, recording, stream, interview, class, or support call.

Abbreviation-aware splitting

'Dr. Smith left.' is one sentence, not two. Titles, initials, and common abbreviations don't trigger a false break.

Every sentence listed

The numbered breakdown shows exactly where the boundaries fell, so an unexpected total is easy to explain.

Drop in a paragraph, an essay, a summary, or a full article — any length works.

Common uses

Assignments with a sentence minimum

Confirm the paragraph hits the number your teacher asked for, and that each one is a real sentence rather than a fragment.

Tightening long-winded writing

Reading your sentences as a numbered list makes the overlong ones obvious in a way that a wall of text never does.

Summaries and abstracts

Many journals and briefs cap a summary at a set number of sentences — check before you submit.

Editing for readability

Short sentences read faster on a phone. The breakdown shows which ones are carrying too many clauses.

Frequently asked questions

Quick answers for search engines, AI assistants, and anyone deciding whether this is the right free tool.

What does the Sentence Counter do?+

It counts how many sentences are in any block of text and lists each sentence separately and numbered, so you can see the shape of what you've written rather than just a total.

How does it handle abbreviations like 'Mr.' or 'e.g.'?+

It knows the difference between a full stop and a dot inside an abbreviation. Titles and initials (Mr, Mrs, Dr, Prof, Jr, St) never end a sentence. Ambiguous ones (etc., e.g., i.e., Inc., a.m., U.S.) only end a sentence when the next word starts with a capital, which is the same cue a reader uses.

Does it count sentences without ending punctuation?+

Yes. Trailing text with no period, question mark, or exclamation point still counts as a final sentence — which matters, because that's exactly the state a draft is usually in mid-edit.

How does it treat '...' and '?!'?+

A run of ending punctuation is treated as one boundary, so an ellipsis or an interrobang counts as a single sentence break rather than three or two.

How many sentences should a paragraph have?+

There's no rule, but the common guidance for academic and web writing is roughly three to five sentences per paragraph — enough to develop one idea, short enough to stay readable on a phone. If a paragraph is running past seven or eight, it's usually carrying two ideas that want splitting.

How many sentences is 100 words?+

Usually five to seven. English averages 15–20 words per sentence in general prose, so 100 words lands in that range. Paste your text in for the actual number rather than the estimate — technical and academic writing skews much longer per sentence.

Why does my count differ from Word or Google Docs?+

Every tool draws sentence boundaries slightly differently, particularly around abbreviations, quoted dialogue, bullet lists, and headings. Seeing the sentences listed individually here tells you exactly which boundaries were used, so you can check the ones that matter instead of guessing at a difference of one or two.

Can I use it to check an assignment's sentence requirement?+

Yes — that's one of the most common uses. Paste your paragraph, confirm you've hit the minimum your teacher asked for, and use the numbered list to check that each one is a real sentence rather than a fragment padding the count.

Does it count words and characters as well?+

This tool is focused on sentences and the sentence breakdown. For word, character, and paragraph totals with frequency analysis, use the Cubix Word Counter or Character Counter — they're linked at the bottom of this page.

Can I download the sentence breakdown?+

Yes. Copy the stats to your clipboard, or download a .txt report with the total and every sentence listed and numbered.

Is my text stored anywhere?+

No. The analysis runs on request and nothing you paste is saved, logged, or reused.

Is this Sentence Counter free?+

Yes. It is completely free with no signup, no login, no download, and no limit on how much text you analyse.
