We leave an additional 20% planning margin. This is not a measured cross-model error range or an official ChatGPT, Claude, Gemini or Grok upload limit.

Use individual TXT chunks, not the whole ZIP, in an AI request. Check whether splitting destroys the meaning of a table or section.
Privacy, caps and browser self-check
File content and names stay in this isolated processing area. The workbench code does not upload files, call AI, run an analytics SDK or use persistent storage. HiseHub's hosting layer may set its existing HTTP-only visit cookie on page/code requests; isolated scripts cannot read it. The surrounding HiseHub page has normal visit analytics. Browser extensions and your device are outside this protection.
Local caps: 12 MiB per file, 100 PDF pages, 300,000 characters, 400 chunks and 45 seconds. Large or unreadable inputs are rejected or clearly marked partial. Passwords, OCR, DOCX, images and malware scanning are not supported.
A self-check deliberately attempts one fixed network request; the processing area's policy should block it before transmission. No file data is involved.
