How to split text into fixed-length chunks
Posting a long note where a character limit applies, sending a message in parts, or handing a document to reviewers in equal pieces all call for the same thing: cutting text at an exact length. Set the length, paste the text, and the pieces appear right away, ready to copy.
The number at the top is the length of each chunk, not the number of chunks. Enter 100 and the text is cut every 100 characters, with the resulting count reported below. The final chunk holds whatever is left, so it is usually shorter; it is never padded with filler, and its exact length is shown. Turning on numbering adds a prefix such as (1/5) to every piece, and because that prefix is not counted towards the chunk length, remember to add it yourself when a hard sending limit applies.
Cutting happens on grapheme boundaries, the units a reader perceives as single characters, so an emoji or a combining mark is never split across two chunks and no broken symbols appear at the edges. A checkbox decides whether line breaks in the source are kept or folded into single spaces before splitting.
Frequently asked questions
It is the number of characters in each chunk. Enter 100 and the text is cut every 100 characters; the resulting number of chunks is shown in the result.
No. It simply holds whatever is left, and both the result panel and the note tell you how long it is.
No. The text is split on grapheme boundaries, the units a reader sees as one character, so emoji and combining marks are never broken across two chunks.
