Landing page captured for the 2026-09-08 issue.

Field notes

The demonstrated workflow begins with a structured brief covering the book’s promise, reader, voice, and constraints, then produces files intended for distribution rather than only a chat transcript. One displayed sample contains 9,862 words across 43 pages; its PDF embeds fonts and clickable contents, while the EPUB has a navigable table of contents and is described as EPUBCheck-validated. Chapbook uses Typst for layout, with EB Garamond body text and Inter headings, and presents three interior themes.
