Private text utilities for everyday formatting
ParagraphSplitter is a small toolkit for writers, editors, translators, and anyone who pastes messy text from Word, PDFs, or spreadsheets. Each tool does one job well — split paragraphs, remove line breaks, drop duplicate lines, convert letter case, or run bulk find and replace — without accounts, uploads, or AI rewrites.
Everything processes on-device in your browser. Close the tab and the draft is gone from our side, because it never left your device. Start on the homepage Paragraph Splitter for sentence-per-line formatting, or open a sister tool above when you need cleanup first.
