Paragraph Splitter

WHAT IT DOES

Paragraph Splitter is a browser extension that scans any webpage for long, dense paragraphs and splits them into smaller, more readable paragraphs based on a configurable sentence threshold. It detects existing paragraph boundaries and intelligently adds new breaks at natural sentence boundaries such as periods, exclamation points, and question marks. By default, paragraphs with more than 5 sentences are split into multiple paragraphs of 5 sentences each, but you can adjust this threshold from 2 to 20 sentences. The tool provides a live preview showing exactly where new paragraph breaks will be inserted, and includes a full undo function to revert all changes instantly. The count display shows how many paragraph splits have been or will be performed. The tool is ideal for writers, editors, bloggers, students, and anyone who wants to improve the readability of web content.

WHERE IT RUNS

Paragraph Splitter works on any webpage that contains text in block elements such as paragraphs, divs, articles, sections, and list items. It runs locally in your browser as a lightweight userscript, scanning text content across the entire page while avoiding script tags, style blocks, and form inputs. It works on blog posts, articles, documentation pages, email drafts, academic papers, and any other text-based content. The tool handles static pages, dynamically loaded content via AJAX, and single-page applications where content updates without page reloads. All processing occurs entirely in your browser—no text is ever sent to any server.

HOW TO USE

After installation, open the floating panel by clicking the extension icon. The panel automatically scans the page and shows a preview of all paragraphs that would be split, with changes highlighted in green. Use the "Sentences per paragraph" input to adjust the threshold—enter a number between 2 and 20 and click Apply. Choose the scope using the dropdown menu: "Entire page" to split all qualifying paragraphs, or "Selected text" to apply only to the text you have highlighted. Each change updates the preview in real time. Click the Preview button to refresh the preview display, the Apply button to commit the splits to the page, and the Revert button to restore all text to its original state. The count display shows how many paragraph splits have been or will be performed. All threshold and scope preferences are saved per domain.

REAL MECHANISM — WHY THIS WORKS

Most paragraph splitting tools use simple character counting or arbitrary break insertion that can split sentences in the middle or create awkward formatting. Paragraph Splitter uses a sentence-boundary detection engine that analyzes text at the sentence level. The engine first identifies all sentence boundaries by scanning for periods, exclamation points, and question marks while handling common edge cases such as abbreviations (Mr., Dr., etc.) and ellipsis (...) to avoid false positives. It then counts the number of sentences in each paragraph and compares this against the user-defined threshold. When a paragraph exceeds the threshold, the engine splits it into chunks of the specified sentence count, preserving natural sentence boundaries. The engine operates at the DOM level, detecting block-level elements and replacing their text content with properly structured paragraph elements. The preview mode uses a styled container with a green left border, showing each new paragraph with a marker to clearly indicate where breaks will occur. The engine processes content in batches to avoid blocking the main thread, and it preserves the original DOM structure by replacing text nodes with structured paragraph elements. This approach ensures accurate, context-aware paragraph splitting without sending any data off-device.

THE PANEL

The floating panel is fully draggable and remembers its position per site, snapping to the edges of the viewport when dragged near them. You can collapse the panel to a small icon to minimize screen distraction and expand it back with a single click. The panel is resizable from the bottom-right corner, giving you more space to view conversion options and statistics. Press the Escape key to close the panel instantly. The panel remains open across page navigation within the same domain, maintaining your current threshold and scope preferences. All preferences—panel position, sentence threshold, and scope selection—are saved per domain for a seamless experience.

PLEASE NOTE

Paragraph Splitter requires the free BotGentz extension to be installed and enabled, as it relies on the cross-extension messaging API provided by BotGentz for DOM access permissions. Because websites frequently update their structure, paragraph detection and splitting may require periodic script updates to maintain compatibility. If the tool does not split paragraphs as expected, please check for updates or report the issue. All text processing occurs entirely in your browser. No page content, text samples, or conversion results are ever sent to any server. The extension does not read, store, or transmit any personal information. It only reads and modifies the DOM of the pages you choose to interact with, and all changes are fully reversible using the Revert function.
