About the Sentence Splitter

The Sentence Splitter breaks a paragraph into individual sentences, one per line. Unlike a naive split on periods, it guards against the classic traps: abbreviations like Mr., Dr., Prof., e.g., i.e. and etc., initials like “J. K.”, and decimal numbers like 3.14 will not cause a false break mid-sentence.

One sentence per line is the format that translation workflows, subtitle editing, text-to-speech pipelines, corpus analysis and careful proofreading all prefer — reading your own writing sentence by sentence is one of the oldest editing tricks there is. A counter reports how many sentences were found, and you can add a blank line between sentences for extra readability.

Splitting happens 100% locally in your browser. Your text is never uploaded, and the tool works offline.

Frequently asked questions

Will it break the sentence at “Mr. Smith”?

No. The splitter checks the word before each period against a built-in list of common abbreviations and titles, so Mr., Mrs., Dr., Prof., St. and similar do not end a sentence.

What about numbers like 3.14 or 1.000?

Periods between digits are treated as decimal points, not sentence endings, so numeric values pass through unbroken.

Why would I want one sentence per line?

It is the standard input format for translation tools, subtitle timing and text-to-speech, and it is a powerful proofreading technique — reading isolated sentences makes long, weak or repetitive ones jump out.

Can it get a split wrong?

Occasionally, yes. Sentence boundary detection without full language understanding is a heuristic, and unusual abbreviations or missing spaces can fool it — skim the output on critical text.

Does it handle question marks and exclamation points?

Yes. Sentences ending in ?, ! and even combinations like ?! are detected just like periods, and quotation marks after the terminator stay attached to their sentence.
