How to Find What a Viewpoint Character Cannot Know in an AI-Assisted Draft
To check an AI-assisted scene in third-person limited, audit each sentence for its source of knowledge: could the viewpoint character observe it, remember it, or infer it from available clues? If the sentence states another character’s private thought, reports an unseen event as fact, or uses knowledge the viewpoint character has not acquired yet, it may have crossed the scene’s viewpoint boundary. This audit is about narrative access, not whether a statement is factually true in the story world.
First, define the viewpoint boundary for the scene
Third-person limited uses third-person grammar, but the information is filtered through a character’s experience. A scene can report what that character perceives, thinks, feels, remembers, believes, and knows; it can also describe other people from the outside. A guide from SHSG English illustrates the difference: a viewpoint character can notice another person’s red eyes and infer that they may have been crying, but the narration should not state that person’s private emotion as certain unless the viewpoint character has a way to know it. SHSG English’s guide to third-person limited
Before reviewing a scene, write down three boundaries: who the viewpoint character is, when the scene takes place, and what that character knows at that point. If the story deliberately changes viewpoint between scenes, record that too. A switch can be valid when it is clear and intentional; an unmarked switch within a scene is a different issue. The key question is not “Is this detail true?” but “Through what route does this scene present it?”
That distinction is useful because knowledge and viewpoint are not always explicitly labeled in prose. In a paper on tracking point of view in narrative, Janyce Wiebe describes how a reader must distinguish a character’s beliefs from story facts and attribute thoughts or attitudes to their source. This supports treating each claim as something to trace, rather than relying on pronouns or a general impression of voice. Wiebe, “Tracking Point of View in Narrative,” Computational Linguistics
Run a sentence-by-sentence access audit
Mark each detail that carries information: physical description, action, emotion, motive, memory, explanation, prediction, and background fact. For every marked detail, ask which of these routes makes it available to the viewpoint character:
Observed: The character can see, hear, smell, taste, or feel it from their position. Check whether an obstacle, distance, noise, darkness, or distraction limits access.
Remembered or known: The character learned it earlier, witnessed it, read it, or has relevant experience. Confirm that the story has established this knowledge before the detail appears.
Reported: Someone told the character, or a message, document, recording, or other source conveyed it. The scene may need to show or establish that channel, and the wording should reflect its reliability.
Inferred: The character draws a conclusion from clues. Keep the clue and the uncertainty visible when the conclusion is not confirmed.
Unavailable: The scene asserts another person’s private thoughts, an event outside the character’s experience, or a fact with no established route. Revise, relocate the information, or make a deliberate viewpoint change.
The list is an editorial tool, not a formal taxonomy imposed by the sources. Its logic follows the craft guidance that the writer should stay with what the character can experience and explain how information not witnessed directly reached them. SHSG’s examples also show how a phrase such as “as if” can signal inference rather than omniscient certainty. SHSG English
A useful annotation is short: detail → access route → evidence in the scene or earlier text. For example: “the guard is afraid → inference → his hand shakes and he keeps glancing at the door.” If the final part is blank, the draft may be asserting more than the character can know.
Check observation, memory, and inference separately
Observation depends on position and attention. “The envelope was open” may be observable if the character can see it. “The letter inside named her brother” requires that the letter be visible and legible, and that the character actually looks at it. A detail can be physically available but still feel unearned if the scene has not directed the character’s attention to it. Consider whether the character is facing the object, occupied with something else, or able to perceive the detail under the conditions described.
Memory depends on what happened earlier. An AI-assisted draft may let a character recall a name, promise, or clue that the story has not yet given them. Trace the knowledge back to a scene, conversation, document, or established history. Also check timing: a character may have learned a fact in a prior chapter, but not before the current scene. Scott Westerfeld’s discussion of limited viewpoint emphasizes that details must fit what the viewpoint character knows, would notice, and can understand; he also cautions against having the character acquire knowledge without a plausible path. Scott Westerfeld, “Single Limited Viewpoint”
Inference is not the same as access to another mind. A character may read a clenched jaw as anger, but that is their interpretation—not confirmed access to the other person’s feelings. Preserve the difference with wording such as “she seemed angry,” “he took it for a warning,” or a free indirect thought clearly colored by the viewpoint character’s assumptions. Whether to use explicit hedging depends on voice and context; the essential check is whether the narration presents an interpretation as certainty.
Watch for common knowledge leaks in AI-assisted prose
Look especially for sentences that explain why a non-viewpoint character acted, describe what that person privately felt, or reveal what happened elsewhere while the viewpoint character was absent. These are not automatically errors: the story may use an omniscient narrator, switch viewpoints, or have the character learn the information later. They become suspect when the scene is otherwise close to one character and provides no route to the information.
A practical warning sign is a sentence that sounds like a neutral explanation of the whole scene: “Mara was relieved he had not noticed the key.” If the viewpoint character is the person being watched, the sentence gives the reader Mara’s private feeling. A limited version could describe what the viewpoint character sees—“Mara’s shoulders dropped”—or place the information in Mara’s own viewpoint in a clearly marked scene. Another warning sign is a character reacting to a secret before the draft shows how they learned it. Track not only whether a fact is true, but when each character gains access to it.
Do not treat every sentence without “she saw” or “he heard” as a breach. Close third-person narration often filters perception without repeatedly naming the act of perceiving. Instead, inspect the content: can the detail belong to this character’s senses, memory, judgment, or knowledge? Westerfeld’s examples distinguish external observations of another person from sensations and opinions that belong to the viewpoint character. Scott Westerfeld
Repair the passage while preserving the scene’s purpose
When you find a detail without a route, choose the lightest repair that keeps the intended effect:
1. Anchor it in perception. Add a cue that places the detail within reach: the character sees a reflection, hears a muffled phrase, or notices a changed expression. Use this only if the scene supports that access.
2. Make it an inference. Keep the clue visible and frame the conclusion as the character’s reading of it. If the character could be wrong, let the prose retain that possibility.
3. Show how the character learned it. Establish a conversation, message, remembered event, or other channel. When the fact is secondhand, let the narration reflect the source’s limits rather than silently turning a report into certainty.
4. Move the information. If the scene needs a private thought or an unseen event, consider placing it in a viewpoint that can legitimately carry it, or revealing it later through evidence or dialogue.
5. Keep the fact out for now. If the scene works without the explanation, withholding it may preserve suspense and keep the reader aligned with the viewpoint character.
As a hypothetical example, suppose an AI-assisted draft says: “Lena was already planning to leave, though Tomas had no idea.” If the scene is in Tomas’s limited viewpoint, the first clause claims Lena’s private intention. Tomas might instead notice that she has put on her coat and moved her bag beside the door, then infer that she may be leaving. The revision preserves the dramatic tension while making the inference belong to Tomas.
Use AI as an auditor, then make the judgment yourself
A focused review prompt can help turn a vague “check the POV” request into a traceable pass. Provide the scene, identify the viewpoint character and the relevant prior facts, then ask the model to list sentences that state private thoughts, unseen events, unearned memories, or conclusions presented as certain. Require it to quote each sentence and identify the proposed route—or say that the route is missing. Ask for possible revisions separately, so suggestions do not quietly become new story facts.
Treat the output as a set of leads, not a ruling. A model can mistake an intentional viewpoint shift for an error, miss information established several chapters earlier, or accept a plausible inference that the text has not actually supported. Verify each flag against the manuscript’s timeline and evidence. This cautious workflow is an editorial recommendation; the sources establish the underlying viewpoint and attribution problems, not the performance of a particular AI tool.
A compact review table can keep the decision clear:
Draft detail: “Mara dreaded the call.”; Who could know it?: Mara, or an omniscient narrator; Route available by this moment?: No, if scene follows Tomas; Decision: Replace with observable behavior or move viewpoint
Draft detail: “The caller sounded furious.”; Who could know it?: Tomas, if he hears the call; Route available by this moment?: Yes, as an interpretation; Decision: Keep as his reading; consider signaling uncertainty
Draft detail: “The caller had read the note.”; Who could know it?: Whoever saw the note read or was told; Route available by this moment?: Not established; Decision: Add evidence, reveal later, or remove
Finish by reading only the flagged passages in scene order. Confirm that each important fact arrives through a coherent route and at the right time. Then read the scene for voice: an access-safe sentence can still sound unlike the viewpoint character if its judgments, vocabulary, or assumptions belong to someone else. The goal is a narration whose information feels available to the character as the scene unfolds.
