Real conversation is mostly noise: greetings, repetition, people talking past each other about nothing. Good dialogue is not a transcript of that. It is the interesting 5%, arranged so it reads like the whole thing.
Here is what separates dialogue that works from dialogue that dies on the page.
Two people who want different things
This is the whole engine. A conversation where both characters want the same outcome has nowhere to go, which is why so much drafted dialogue reads as two people agreeing pleasantly for half a page.
Before writing any exchange, know what each person wants from this conversation, not from the story. One wants a confession. One wants to leave. One wants to be forgiven without admitting anything. Now the scene has a shape, and it can end with someone not getting what they came for.
Start late, leave early
Cut the greetings. Cut the arrival. Cut the "so, how have you been."
Enter the scene at the first interesting line and leave on the line that lands, before anyone says goodbye. Readers fill in the rest without noticing. Most flat dialogue scenes get 40% better from deleting the first four lines and the last two, and nothing else.
Nobody answers the question
People deflect, change the subject, answer a different question, or say something technically true. That is where subtext lives.
"Did you go and see him?" "The traffic was terrible."
That is a yes, a reluctance, and a relationship, in nine words. Written as a direct answer it would be one word and no information about anyone.
Not every line should dodge, or it becomes a tic. But a conversation where every question receives a direct honest answer is an interview, not a scene.
Use "said"
"Said" is invisible, and invisible is what you want. Readers do not register it, which lets them stay in the conversation.
What to avoid:
- Decorated tags. Ejaculated, riposted, opined. They pull the eye off the line.
- Adverbs propping up weak lines. "'I don't care,' she said angrily" is a line that failed and an adverb sent to rescue it. Rewrite the line so the anger is in the words.
- Impossible tags. You cannot smile or laugh a sentence.
Action beats beat tags anyway. "She put the glass down harder than she meant to" tells you the tone, keeps the scene physical, and never uses the word angry.
Give each person a different rhythm
Cover the name tags. If you cannot tell who is speaking, the characters have one voice between them.
Rhythm carries most of this. Some people speak in fragments, some cannot stop qualifying, some get more formal as they get angrier. That is far more durable than accents or catchphrases, which age badly and get tiring by chapter five.
The specific AI dialogue problem
Drafted dialogue has a signature, and once you see it you cannot unsee it. Everyone is articulate. Everyone finishes their sentences. Everyone is emotionally available and says exactly what they mean. Characters explain their own feelings out loud, and nobody interrupts anybody.
Real people are worse at talking than that, and much more interesting for it.
What to do with a flat generated exchange:
- Delete every line where someone states their emotion. Let the behavior carry it.
- Make one character refuse to engage. Instant tension.
- Cut the first four lines.
- Give one of them a reason to lie, even a small one.
- Read it aloud. This catches more than any other technique on this page. If your mouth stumbles, a reader's ear will too.
The AI writing assistant is genuinely useful here, but at the line level: ask for three sharper versions of a flat exchange, or the same beat with one character refusing to answer. Whole conversations generated unattended are where the sameness creeps in.
Dialogue in comics and scripts
The rules shift when dialogue is the whole medium.
In comics and webtoons, the art is doing the description, so lines have to be short. A bubble that fills a quarter of the panel is too long, and the picture already told the reader what the face is doing.
In scripts there is no narration at all. Everything a character wants has to arrive through what they say and what they refuse to say. Writing a short scene as a script is a genuinely good exercise even if you are writing prose, because it strips out every crutch.
The test
Read the scene out loud, both parts. Where you get bored, a reader stopped two lines earlier.
