Sentence Splitter

Break a paragraph into one sentence per line, handling abbreviations and decimals correctly.

Splitting text into sentences is harder than cutting on every full stop, because abbreviations, decimals and initials all contain one. This tool protects around 20 common abbreviations, decimal numbers and initials before splitting, then reports the length of each sentence so you can find the ones worth shortening.

Frequently asked questions

Why is splitting on full stops not enough?

Because abbreviations, decimals and initials all contain one. "Dr. Smith paid £3.50 at 4 p.m." has five full stops and one sentence. This tool protects around twenty common abbreviations, decimal numbers and initials before splitting.

What sentence length should I aim for?

Plain-language guidance suggests an average of 15 to 20 words, with none over about 25. The tool reports how many exceed that, because splitting the longest sentences is the single most effective way to improve readability.
