Let’s kill the misconception first: AI is bad at outlining your novel for you. Ask ChatGPT to “outline a fantasy novel” and you’ll get the same beige three-act skeleton everyone else gets. Where AI is genuinely excellent is pressure-testing an outline you built — finding the sagging middle, the unearned ending, the character who exists only to deliver exposition.
Here’s the five-step method I use on my own manuscripts, with the actual prompts.
Step 1: Stress-test the premise before anything else
Don’t outline a weak premise — you’ll just organise the weakness. Paste this into Claude or ChatGPT:
“Here is my premise: [PREMISE]. Attack it: Where is it derivative? Where does the conflict fizzle? What’s the most obvious version a lazy writer would produce? Then show me the version that avoids all three.”
If the “obvious lazy version” it describes sounds uncomfortably like your plan, you just saved yourself a dead draft.
Step 2: Interview your protagonist before plotting
Beats built before character are structurally correct and emotionally hollow. Run a wound interview: have the AI interrogate your protagonist in their own voice about the worst day of their life, one question at a time, then summarise the wound, the lie they believe, and the mask they wear. Plot grows from that gap.
Step 3: Build the 15 beats — yourself
This part is your job. I use the Save the Cat 15-beat structure (full plain-language breakdown here). Write one sentence per beat. Resist the urge to have AI fill in beats you’re stuck on — a beat that resists you is diagnostic information, not a box to delegate.
Step 4: Run the therefore/but chain
Now hand your beat list back to the AI:
“Rewrite my outline as a ‘therefore/but’ chain. Flag every place events connect with ‘and then’ — those are my dead spots.”
Scenes linked by “and then” are episodic filler; scenes linked by “therefore” or “but” are causal story. This single prompt is the fastest saggy-middle detector I know.
Step 5: Attack your own midpoint and ending
Two final interrogations: ask for three alternative midpoint reversals that force your protagonist from reactive to proactive (pick the one that scares you), and ask the AI to argue that your ending is unearned — then check whether act one actually plants what it says is missing.
The complete system
If you want this as a guided workflow instead of scattered prompts: The Novel Architect Workbook walks every planning stage in a fillable PDF, and The Prompt Vault has the matching interrogation prompt for each section — 100 in total, covering premise to launch. They’re bundled together as The Complete Novelist’s Stack.
One honest caveat, as always: the AI pressure-tests, you write. Outlines built this way still fail if the sentences on top of them aren’t yours.
