Every novelist has a book with a hole in it. A character walks into a room that was locked two chapters ago. A detective forgets a clue the reader saw him find. Somebody who’d never lie to her sister lies to her sister, and nothing in the book explains why.
The first two are annoying. The third one kills books.
Readers forgive a lot. They’ll forgive a wrong eye color, a timeline that’s off by a day, even a gun that changes caliber halfway through. What they won’t forgive is a person who stops being a person and turns into a game piece. That’s the plot hole that matters, and it’s the one most writers never check for, because they’re too busy hunting the small stuff.
I’ve written a lot of twisty novels, and I write them out of order. I start with five or ten big plot points and write outward from each one, then stitch the pieces together. I call it the ink blot method. It works, and it also means every book I finish has seams where two chapters written months apart have to agree with each other. So I check for holes on purpose, every time.
What is a plot hole in a novel?
A plot hole is any place where the story contradicts itself or asks the reader to accept something the book hasn’t earned. They come in three flavors.
Continuity holes are factual. The scar is on the left cheek in chapter two and the right cheek in chapter twenty. Logic holes are mechanical. The hero could have called the police in act one and ended the story, and the book never says why he didn’t.
Character holes are the third kind, and the worst. A character makes a choice because the plot required it, and nothing in who they are would produce that choice. In my Plot Handbook I call it the warehouse problem. You need your hero in the warehouse at midnight, so you send him there, even though nothing about him would take him there. You got your scene. You lost the reader.
One reader in a writing group described a published novel where the hero picked up a steaming cup of coffee and put it in his pocket. He did it four times in the first six chapters. She returned the book. That’s a continuity hole, and it’s funny. The character hole is quieter, and it does more damage, because the reader doesn’t laugh. She stops believing.

Why can’t writers find plot holes in their own books?
Because you know what you meant.
When you reread your own manuscript, your brain fills every gap with the version that lives in your head. You know why she lied to her sister. You worked it out in a notebook in March. The reader never saw the notebook.
Writing in pieces makes it worse. You read each chapter right after the one before it, so each one feels fine compared with its neighbor. Nobody holds chapter three up against chapter thirty. I wrote about this in continuity drift, where a long draft slowly forgets its own facts, and the same thing happens to human drafts written over a year.
Time helps a little, so put the book away for a month and you’ll read it cleaner. A month doesn’t fix a brain that already knows the answer, though.
How do you check a novel for plot holes?
I use AI as a checker, and the checks come straight out of my Plot Handbook. I wrote that book about plot as the output of character psychology, and the same ideas turn into a very good inspection list.
The first check traces each major character’s decisions across the whole manuscript. What does this person want? What are they afraid of? What would they refuse to do, even to win? Then every significant choice they make gets measured against that pattern. Anywhere a character acts against their own wiring without a pressure that explains it, the tool flags it.
That’s the warehouse check, and it finds the holes I care about most.
The second check goes beat by beat. For every major plot event, does it grow out of a character’s response to pressure, or did it just happen because the outline said so? A beat that could be handed to any competent protagonist is a weak beat, and a beat that nobody’s psychology produced is a hole.
The third check is plain continuity. Names, ages, scars, eye colors, who knows what and when, locked doors, the number of days that have passed. Machines are good at this kind of bookkeeping, and they don’t get bored on page 300.
Then I read every flag myself. Every one.
Can AI find every plot hole in a manuscript?
No. Nothing finds them all, and anyone selling you a tool that does is selling you something.
AI catches a lot. It also invents problems. One writer in that same group said her tool found new plot holes every time she ran it, and not all of them were real. Some flags are sharp. Some come from the tool misreading a scene. A few are the tool wanting a different book than the one you wrote. So treat each flag as a question. Is this a real hole, or did the tool miss a setup in chapter six? The ones you argue with yourself about are the ones worth fixing.
And don’t let the tool fix the holes for you. People bring me books that a machine plotted, and they’re full of puppets, characters marching wherever the outline sends them. The tool is great at spotting the puppet moments. It’s terrible at deciding what a real person would do instead. That part’s yours.
Should you check plot holes chapter by chapter or across the whole book?
Both, for different reasons.
Chapter checks catch local slips while the scene is fresh. Did the coffee go in the pocket? Did she walk in twice in the same page? Those are cheap to fix right away. The whole-book check catches what chapter checks can’t see. A character’s pattern only shows up across the full arc. A decision in chapter twenty-two only looks wrong next to who she was in chapter four. If you only ever check one chapter at a time, you’ll never catch the hole that matters most.
For a series, add a bible. When I ghostwrite a multi-book series, I keep a reference document with every established fact, because I don’t trust memory, mine or anyone else’s. The same habit works for a single novel. Any fact a later chapter depends on goes in the list.
What other ways do writers catch plot holes?
Plenty, and most of them work best stacked on top of each other.
Listening is a big one. Several writers in that group run their manuscripts through text to speech and listen while they walk the dog. Your ears catch what your eyes skim past, like a character entering the same room twice on one page or a sentence that trips over itself. Word’s read aloud feature does the job for free.
Others check the draft against the plan. If you outlined, wrote beats or built a story grid, hold the finished book up against it and look for the places where the draft wandered off and never came back. Some of those wanderings are improvements. Some are holes.
Beta readers catch a different kind of hole, the one where the logic holds up but a reader still doesn’t buy it. If two or three of them stumble at the same scene, believe them. A style sheet helps more than people expect, too. Keep a short list of every character’s age, looks and key facts, plus every place, and check against it as you go. Write it down once and you stop guessing.
How do you fix a plot hole once you find it?
Continuity holes are easy. Pick the right version and change the wrong one.
Logic holes take a little more work. You need one line or one scene that closes the door the reader saw open. Why didn’t he call the police? Give him a reason, and plant it early.
Character holes are where most writers get it wrong. The lazy fix is a line of explanation: “She didn’t know why she did it.” Readers see through that instantly. The real fix comes from the handbook. If you need a character somewhere and her psychology wouldn’t take her there, find the pressure on her wound that would. Make the warehouse the only place she could go. Then the beat you needed shows up feeling inevitable, and the reader never knows it was ever a hole.
If no pressure works, the book is telling you the beat is wrong. Cut it and find another way through.
A clean book is a book readers trust
Readers will forgive a slow chapter. They’ll forgive a plain sentence. What they won’t forgive is the moment a person on the page does something only because the writer needed it, because after that they stop believing anybody in the book is real.
Check for that first. The scars and the eye colors are the easy part.
The full method is in the Plot Handbook, and more on revision lives in the Writing Hub. If you want another set of eyes on a manuscript that isn’t working, my book coaching is built for exactly that.
