Local · breaks on spaces, not mid-word

Splits long text into chunks of at most the length you set, breaking at spaces so words stay whole. The default of 280 is a post on X.

How to use the text splitter

1 Paste your text into the first box.

2 The result appears immediately.

3 Copy the result, or save it as a text file.

Breaking on whitespace is what separates this from a plain substring split, and it is the part that matters — chunks that end mid-word are unreadable. The one case where a mid-word cut is unavoidable is a single word longer than the chunk size, such as a URL, and that is handled by cutting it rather than by producing an oversized chunk. Useful sizes to know: 280 for a post on X, 160 for a single SMS, 2200 for an Instagram caption and 3000 for a LinkedIn post. Below 160 characters an SMS is one message; above it, it is split and billed as several.
