A text splitter breaks large blocks of text into smaller, manageable chunks. Useful for splitting content for AI prompts, social media posts, email batches, or any system with character or word limits.

How to Use the Text Splitter
The text splitter is designed for anyone who needs to break large blocks of text into smaller pieces — whether for AI prompt limits, social media character caps, email campaign batches, or any system with content-size restrictions.
Step 1: Paste Your Text
Copy your source text — an article, a document, a dataset — and paste it into the input box. The tool handles any size of text your browser can hold.
Step 2: Choose a Split Mode
Four modes are available. By character count is most useful for AI models with token limits — a 500-character chunk stays well under most 4K context limits. By word count is better for editorial content like blog sections. By line count works for structured data or spreadsheet rows. By custom delimiter handles structured text like CSV sections, paragraph markers, or custom separators.
Step 3: Set the Chunk Size or Delimiter
Enter the target size (characters, words, or lines per chunk) or the delimiter string. When splitting by character count, the tool always breaks at a word boundary — it will never cut a word in half.
Step 4: Copy the Chunks
Each chunk is numbered and has its own Copy button. Use Copy All to grab every chunk at once, with numbered separators so you can paste them into a document and see exactly where each chunk begins.
Common Use Cases
Splitting long articles into sections for social media threads. Breaking documents into 2000-character pieces for ChatGPT or Claude prompts. Dividing a large email list into batches. Separating CSV or TSV data by blank-line groups. Chunking a speech or script by paragraph for teleprompter segments.
FAQ
How does the Text Splitter work?
Paste your text and choose a split mode: by character count (splits near word boundaries), by word count (every N words), by line count (every N lines), or by a custom delimiter (any string or character you specify). Click Process to see the chunks.
Does character split break words mid-word?
No. When splitting by character count, the splitter finds the nearest word boundary (space) before the target character count, so words are never cut in half.
What delimiters can I use for custom splitting?
Any string works as a delimiter — a single character like a comma or pipe, multiple characters like ' | ', or even a word. The text is split at every occurrence of that delimiter.
Can I copy individual chunks?
Yes. Each chunk has its own Copy button. There is also a Copy All button that copies all chunks joined by a separator line.
Is this tool free?
Yes, completely free with no account required. All processing happens in your browser — your text never leaves your device.
Is my text private?
Yes. The tool runs entirely in your browser. No text is ever sent to a server, making it safe for confidential content.
What is the maximum text size?
There is no hard limit — the tool handles texts of any size your browser can hold in memory. Very large texts (millions of characters) may take a moment to process.
