Claude generates a 254-page custom Spanish textbook in one session
nimbledoor · reddit · 2026-10-19
A Czech user had Claude create a textbook that didn't exist: LATAM Spanish with a Mexican focus, taught for Czech speakers with C1 English. Using Opus 5.5 High (60-70% of the 5-hour allowance), Claude produced a 254-page PDF with a full course to B1 plus a grammar summary. Prompt requirements included established teaching methods, links to listening exercises, real-world language including slang and swearing, current controversial topics, and regional differences. The author is happy with the result and offers to share the PDF.
