AI-assisted prose often becomes recognisable for reasons that have little to do with individual words. The narration may explain every emotion, give several characters the same polished voice or move through a scene with a steady rhythm that never quite feels lived in. Revising those passages is not simply a matter of replacing formal phrases with casual ones. For novelists, the more useful question is this: does the writing sound like a particular person telling this particular story?
Making AI-written text sound more human means restoring decisions that feel authored. That includes the narrator’s attitude, a character’s private logic, the details a point-of-view character would notice and the things they would avoid saying. A broad manuscript edit can help, but fiction benefits from a more focused process that moves from the shape of the story to the sentence level.
Start with the authorial voice, not the vocabulary
A common mistake is to begin by hunting for words that sound artificial. That can produce smoother sentences without making the passage more personal. First, identify what the prose should feel like. Is the narrator intimate, suspicious, comic, restrained or impatient? Does the point-of-view character interpret events generously, defensively or with limited understanding?
Read a page of the AI-assisted draft beside a passage you wrote without assistance. Do not compare only word choice. Compare the distance between narrator and character, the amount of explanation, the length of sentences and the kinds of details that receive attention. Mark places where your own writing makes a surprising observation or leaves something unsaid. Those choices are evidence of voice.
Then revise the AI-assisted passage around the character’s perspective. Replace neutral observations with details that reveal what this person wants, fears or misunderstands. A nervous character may notice the exit, a stain on a sleeve or the timing of someone’s breathing rather than the room’s complete appearance. The goal is not to make every sentence unusual. It is to make the selection of details feel motivated.
Revise fiction in separate passes
Separating the work into passes helps prevent sentence polishing from hiding larger problems. Guidance on editing AI-generated text commonly distinguishes structural editing, voice, verification, wording and the addition of personal detail. For a novelist, those passes can be adapted to the demands of scenes, characters and point of view.
First, check the scene’s purpose
Before editing individual lines, ask what changes during the scene. A character might gain information, lose control, make a decision or misunderstand another person. If nothing changes, more vivid wording will not solve the underlying problem. Cut repeated setup and move the scene towards the decision, discovery or conflict that gives it a reason to exist.
Look also at the balance between action, reflection and description. AI-assisted passages can make every element equally explicit, creating a smooth but static sequence. Give important moments more space and allow connective material to remain brief. Human revision often means choosing what not to explain.
Then restore distinct character voices
Each important character should have a different way of noticing, interpreting and responding. Voice is not a collection of catchphrases. It can appear in sentence length, evasions, metaphors, levels of certainty and the subjects a character refuses to discuss.
Read dialogue without its speech tags and ask whether you can identify the speaker. If two characters sound interchangeable, change their intentions rather than merely adding slang. One person may answer the question asked. Another may redirect it. A third may use excessive politeness to conceal anger. These differences create human texture because they connect language to social pressure.
Replace emotional explanation with observable behaviour
Fiction becomes less convincing when it names an emotion and then repeats that emotion through dialogue and action. Instead of writing that a character is anxious, show the action anxiety produces in this character. They may reread a message, arrange objects on a table or speak too quickly to prevent a question.
This does not mean emotion should never be named. Direct interior language can be powerful when it belongs to the character’s natural thought process. The useful test is whether the sentence adds an insight or simply labels what the reader already understands. If it only labels, replace or remove it.
Make the prose less predictable at sentence level
AI-assisted fiction may develop repetitive rhythms even when every sentence is grammatically correct. Read the passage aloud. Listen for several sentences with the same length, the same clause structure or the same pattern of description followed by explanation. Vary the rhythm where the scene’s pressure changes. Short sentences can create shock or resolve. Longer sentences can follow a wandering thought, a complicated observation or a moment of hesitation.
Do not vary sentence length mechanically. Rhythm should follow attention. A character fleeing across a street will not process the world in the same way as a character waiting for a difficult answer. The syntax should reflect that difference.
Also examine general statements about people, feelings and situations. Phrases that could apply to almost any character often weaken a scene. Replace them with a concrete action, a specific memory or an observation that only this narrator would make. Specificity is more useful than forced informality.
Use continuity as a humanising edit
Continuity errors make prose feel assembled rather than experienced. Check names, relationships, locations, timelines, objects and physical actions. If a character puts a key on the kitchen counter, the next paragraph should not treat the key as still being in a coat pocket unless the change is intentional.
Character continuity matters just as much. A cautious person should not suddenly reveal private information without a reason. A character who has not learned a fact should not act on it merely because the draft needs the plot to advance. Keep a simple record of what each character knows, wants and has done. During revision, compare each scene against that record.
Fluent prose can still contain a contradiction, so read for the story’s accumulated reality rather than only for the quality of isolated sentences. Check each passage against the character and scene information established elsewhere in the manuscript.
Let AI critique specific problems, not define the voice
If you use an AI tool during revision, give it a narrow editorial task. Ask it to identify repeated sentence patterns, possible continuity conflicts, unclear references or places where a character’s reaction seems unsupported. Then decide yourself whether the observation is correct and how to revise the passage.
A broad instruction to make prose more human can flatten the writing towards a generic idea of naturalness. It may also remove deliberate formality, regional phrasing or an unusual narrative habit that gives the novel its identity. Treat suggestions as questions for the author, not as replacements for authorial judgment.

Finish with a slow, human read
After the structural, character, continuity and sentence passes, read the chapter as a reader rather than as an editor. Where did your attention drift? Which line sounds like something no person in this story would say? Where did you feel the scene instead of being told what to feel?
Keep revisions that make the story more precise, more specific and more faithful to its characters. Remove revisions that merely add decoration. AI-assisted prose sounds more human when it contains the irregularities of intention: a biased observation, an interrupted thought, a badly timed joke, a meaningful omission or a detail chosen because this character would notice it.
The final standard is not whether the text passes as human according to a tool. The useful standard is whether the prose has a clear intelligence behind it, whether each scene earns its place and whether the reader can sense a particular author making particular choices.
