AI that can’t break your story.
Characters keep their names. Your magic system stays coherent. Scripture and citations stay real. OpusDraft checks every output against your rules — and fixes what breaks before you ever see it.

The problem has a name: drift.
Every AI tool eventually forgets what you locked in. Here’s the difference that makes.
A five-step editorial pass that stops the moment your work holds — it runs only as far as needed.
Two paths
Most AI tools and OpusDraft are built to maximize different things.
Most AI writing tools
optimize for
- Output speed
- Novelty
- Ideation
- Generation volume
- Improvisation
OpusDraft
optimizes for
- Compliance
- Consistency
- Memory
- Structure
- Restraint
One approach improvises. The other follows the work.
What makes OpusDraft different
Seven behavior guarantees — each one something you can see, not a marketing line.
Preservation
Your locked facts stay locked. Canon enforcement is hard refusal, not optional context.
Verification
Output is checked before you see it. OpusDraft verifies first — most tools verify after, if at all.
Refusal
Won't invent scripture, citations, stats, or names. When it doesn't know, it says so.
Restraint
When your prose is already right, it returns "No changes needed" — and tells you why.
Inheritance
Your decisions travel across every book in a series. Book 3 sees what you locked in Book 1.
Reversibility
Every AI edit is snapshotted with a side-by-side diff. One-click restore, itself reversible.
Trust UX
Enforcement you can see: Apply/Discard panels, drift indicators, refusal banners, Cmd+K search.
Books. Sermons. Keynotes. Pitches.
One engine, two modes. Novels see “Canon.” Sermons see “Facts.” Same enforcement — the right language for long-form work where every detail has to hold. Fantasy and series writers feel it first: the more world you build, the more there is to keep from breaking.
What OpusDraft is not
It’s not a one-click novel writer. It won’t write a book while you sleep.
It’s for people who want to write their own work — with AI doing what it’s good at: drafting, tightening, polishing, catching breaks. You keep the voice, the vision, and every final call. No prompts. No reminders. No babysitting. It just follows your rules and checks itself before it answers.
“I’m not a guru. I’m a writer who got tired of fixing the AI instead of writing. So I built a system that locks in your canon, rules, and sources — and refuses to let the AI break them.”
— Paul, Founder of OpusDraft
