Real talk for anyone using Claude to write novels
If you're on Claude Max (I am - $100-200/month), there's a decent chance 75% of your budget is going nowhere. Not to your books. Just... evaporating.
I tracked this in my own operation and honestly the numbers were a little embarrassing. Here's what the main leaks were:
**Loading huge prompt files fresh every single session.** If you have big structure/architecture files for your book and you're pasting them into every new chat, you're burning 15-30k tokens BEFORE you write a single word. Every. Session.
**Running heavy drafting during peak hours.** Since March 2026 Anthropic adjusted usage limits during peak hours (5–11am Pacific). Your budget drains measurably faster in that window. I shifted my heavy drafting to evenings EST and the same plan goes noticeably further.
**Sending 3 messages when you could send 1.** Every new message forces Claude to re-read your entire conversation history. By message 30 you're paying 31x what message 1 cost. Batch your questions.
The fixes that actually moved the needle for me:
Moved my big structure files into Claude Projects — they cache, reload is essentially free
Evenings only for heavy production sessions
One prompt with multiple questions instead of back-and-forth
If you're doing serious book production with Claude, this stuff compounds fast. Went from hitting my weekly limit mid-week to running full 7-day production cycles on the same plan.
Not magic. Just plugging leaks
