Split a paragraph into sentences, one per line

How to use the sentence splitter

1. Paste your text into Paragraph.
2. Tick Also split at every line break if each line is already a separate sentence, such as in subtitles or notes.
3. Tick Number the sentences to get “1.”, “2.” and so on in front of each one.
4. Read the Sentences count and copy the list under One sentence per line.

What it does and when to use it

Working sentence by sentence is easier on a list than in a block of prose.

• Editing. Spot sentences that are too long or start the same way. Paste the list next to the word counter to check their length.
• Translation and subtitles. Feed one sentence per line into a translation sheet or a subtitle file.
• Language learning. Turn a reading passage into numbered sentences for exercises.

A simple split at every full stop breaks text like “Dr. Smith” or “2.5%” in the wrong place. This tool avoids those mistakes. For a plain split at a character you choose, use the text splitter.

How it works

The text is first divided into paragraphs at blank lines (or at every line break, if you ticked that option). Inside each paragraph, extra spaces and single line breaks are squeezed into single spaces. The tool then looks for ., !, ? or …, plus any closing quotes or brackets, followed by a space or the end of the text. A candidate break is skipped when:

• the word before a full stop is a known abbreviation, a single letter, or dotted initials like U.S.;
• the next word starts with a lowercase letter, as in “Wow!” she said.

A decimal like 2.5 is never a candidate, because no space follows the dot. Everything runs in your browser.

Worked examples

These outputs come from the tool’s own function.

Abbreviations and decimals. “Dr. Smith arrived at 9 a.m. on Monday. She said: “It works!” Did it? Prices rose 2.5% in the U.S. last year. Nobody was surprised.” gives Sentences: 5. One line reads Prices rose 2.5% in the U.S. last year., still in one piece.

Numbered output. “It costs 2.5 dollars. Fine.” with Number the sentences ticked gives 1. It costs 2.5 dollars. and 2. Fine.

Quotes and figure references. ““Wow!” she said. We left. See Fig. 3 for details.” gives three lines. The exclamation inside the quote did not split, because “she” is lowercase, and “Fig.” is on the abbreviation list.

Limits and tips

• Abbreviations outside the list, such as “Ft.” in “Ft. Worth” or “Univ.”, still cause a wrong split when the next word has a capital.
• Sentences without end punctuation run on until the next blank line, unless you split at line breaks.
• Extra spaces are squeezed. To tidy spacing in the original text instead, use remove extra spaces.
