Sentence Repeater: Repeat a Sentence Online

Sentence repetition with automatic punctuation

This tool is for repeating complete sentences. It automatically adds a period at the end if you didn't include one, so your output reads as proper sentences whether they're on separate lines or running together.

Three layouts

One per line: Classic "Bart Simpson chalkboard" format — each sentence on its own line.
Single paragraph: Sentences run together with single spaces. Reads as one long paragraph.
Numbered: Each line prefixed with 1., 2., etc. Good for ordered lists or punishment-writing.

Common uses

Writing "I will not [X]" lines for school detention (whether you're the teacher or the student)
Generating affirmation lists ("I am capable") for journaling templates
Creating sentence-repetition tests for language learners
Bulk-creating identical comment text for testing comment systems

Common questions

Frequently asked.

Because the most common use case is writing many copies of a complete sentence — and complete sentences end in periods. If your input already ends with ., !, or ?, it's left alone.

Not in this tool — each run repeats one sentence. For multiple different sentences, use the line repeater: put each sentence on its own line in the input.

Yes. If your input ends with ! or ?, the punctuation is preserved. Only if you forgot a sentence-ending mark does the tool add a period.
