Q: Prompting
Jumped to Tier 2 and created a human model. Next, I'll upload sources and start my first book. I need help with:
a) The prompt limit is 6,000 characters, too short for including the table of contents, style guidelines, tone, goals, target audience, and formatting. I realize the tool is for drafting, not full books. Is it smart to include more instructions in the sources and the point to them in the prompt itself?
b) Can I name the sources with chapters reference AKA "Chapter 8 - TOPIC.PDF" to help the tool understand where to fish?
c) Does it make sense to combine b) with splitting a textbook in small single .pdf/.md parts rather than uploading the whole thing as one big block?

Oct 18, 2025A: a) Instructions in the sources will NOT guide the book generation and, depending on what the AI brainstorms, might never be read at all. Youbooks will use provided sources just like the internet, it will search among them when it wants to write on something, and if it finds something useful, it will use it. Crucially, it has already decided what to write on before it searches - therefore, the sourcs do not guide the book. There is a setting to take some "inspiration" from the sources, but this is not nearly enough.
I am afraid the 6K word limit is a trade-off we've made between context length, system stability, and cost.
b) Greta question. The AI cannot see the file name you uploaded (all files become on big source), so do not reference the file. You can try referencing specific headings inside the sources. Most importantly, make sure the content is relevant.
c) It will not make any difference.
If your use case demand that the sources heavilly guide the book manuscript, then youbooks might not be the right tool for you. The idea of sources in youbooks is to supplement the AI knowledge where it lacks. This is in contrast to, for example, Magic Bookifier which takes a prompt + source of up to 50K words and outputs a book of 25-30K words.
