What are the limits of Text Chunker?
Up to 250 chunks, size 1–50,000 units. Overlap must be smaller than the chunk size. Characters are Unicode grapheme clusters, words are whitespace-separated and paragraphs are separated by blank lines. Word/paragraph modes normalize separators. These are not model-token counts. ZIP export contains numbered UTF-8 text files and a manifest. Text and files stay in browser memory and a local worker. No uploads, account access, network lookups or automatic storage. Refreshing clears your work. Input is limited to 500 KB and generated output to 1 MB; processing times out after five seconds. Downloads and clipboard copies contain the output you choose.
