Sentence splitter
Paste any text and this tool splits it at sentence boundaries, putting each complete sentence on its own line. It recognizes the standard English sentence-ending punctuation: periods (.), exclamation marks (!), question marks (?), and ellipsis (…). Sequences like ?! or !! are treated as a single boundary, so "Really?! Yes!" becomes two sentences, not three.
Each sentence keeps its terminating punctuation attached, so you get "Hello world." on one line and "How are you?" on the next. The trim option (enabled by default) removes extra spaces around each sentence and drops any blank lines that would result, leaving you with clean, uniform output.
This is useful for writers, editors and content creators who want to review their work sentence by sentence, one per line. It's also helpful for data processing, text analysis, or preparing input for tools that work on whole sentences. If you have a wall of dense prose, splitting it this way makes it far easier to spot sentence fragments, awkward phrasing or repetition.

FAQ
What counts as a sentence ending?
A period (.), exclamation mark (!), question mark (?), or ellipsis (…). Combinations like ?! or !! are treated as a single ending. Text without any of these marks will produce no sentences.
What does the trim option do?
When enabled (the default), it removes extra spaces before and after each sentence and drops empty lines. When off, it preserves the original spacing around the punctuation.
Can I use this for other languages?
Yes. The tool recognizes the same punctuation marks regardless of language, so it works with English, Spanish, German, French and many others. It may not handle abbreviations that end with periods (like "Dr." or "U.S.") perfectly — each will become its own sentence.
Is my text uploaded anywhere?
No. The tool runs entirely in your browser and your text never leaves your device.
