Text Splitter — Split Text into Chunks
Split long text into chunks by characters or words, breaking on spaces.
Splits long text into smaller pieces that fit a chatbot or API context limit, breaking on spaces so words stay whole. Paste each chunk in order. Runs in your browser.
Paste a long document and split it into smaller chunks that fit a size limit — by character count or word count — breaking on whitespace so words aren't cut in half. Each chunk is numbered with its own copy button. Perfect for pasting long text into AI chatbots and APIs that have a context or character limit. Runs in your browser.
How to use the Text Splitter
- Paste your long text.
- Choose to split by characters or words and set the limit.
- Copy each numbered chunk in order.
Frequently asked questions
Does it cut words in half?
No. It prefers to break on a space or line break near the limit, so words and (usually) sentences stay intact across chunks.
Why split text for AI chatbots?
Chatbots and APIs accept only so much text at once. Splitting a long document into limit-sized chunks lets you feed it in sequentially without errors.
Character or word chunks — which should I use?
Use characters to match a strict input limit, or words for a rough, more readable split. Tokens are roughly ¾ of a word, so leave headroom under a model's token limit.
