Many writers come to AI with a premise and ask it to help them write.

That works fine — until you're 30,000 words in and realize your amateur sleuth has no business being involved in the mystery, your suspects are thin, and the community you built in chapter one has no real bearing on the plot.

The lack of structure is the problem.

Here's what I've noticed after building 200+ novel packages: cozy mystery is one of the most structurally demanding genres to write with AI assistance, because the genre has rules that aren't about prose — they're about architecture.

The amateur investigator needs a credible reason to investigate. The community needs to generate suspects naturally, not feel stapled on. The red herrings need to be plausible given what the reader knows about the world. The resolution needs to feel earned, not handed down.

If you don't give AI those structural parameters upfront, it'll give you scenes that don't add up to a cozy mystery.

The fix is boring but it works: before you write a single scene, define the trope combination that's doing your structural work. Not just "amateur sleuth" — but amateur sleuth + what setting, what community dynamic, what built-in reason to investigate.

That combination is where the architecture lives. Once it's locked, AI assistance gets dramatically more useful because every prompt has a framework to land in.

(by request, I put together a free one-pager on cozy mystery trope combos that do this kind of structural work — happy to drop the link in the comments or via DM if anyone wants it.)
