Power in the staging
Who is seated, who has the door behind them, who is lit and who is in shadow. Decide this first and the lines arrive with an imbalance already in them.
Stage two people in one frame, decide who stands, who sits and where the light falls, and get a scene still that reads as a real exchange.

What to settle before you ask for lines.
One person needs something from the other in this scene, and the other needs something different. Two clear wants turn a description of a chat into an exchange with friction in it.
Decide who speaks in long sentences and who answers in three words, who uses names and who never does. If both people sound like the same writer, nothing later in the prompt will fix it.
Say the lines at speaking speed and cut every sentence you would not actually say. Repeat the ask with the cut version and the rhythm tightens on the second pass.
Each one already has a power balance, an hour and an exit.

Try This StyleSix things that decide whether the exchange reads as a scene.
Who is seated, who has the door behind them, who is lit and who is in shadow. Decide this first and the lines arrive with an imbalance already in them.
A single location and a stated time keeps the exchange from drifting into a summary of a relationship. Scenes that wander usually started without a place.
Real conversation overlaps. Ask for one line that gets cut off and one question that is never answered, and the passage stops sounding like two essays taking turns.
People rarely say each other's names twice in a minute. Keep one use at the moment it matters and the line lands harder than a repeated label.
Two people talking about a kettle can be a scene about leaving. Give the pair a small concrete task and let the real subject stay under it.
Generated dialogue tends to explain itself at the end. Deleting the final exchange is the fastest edit available and almost always improves the scene.
I needed a tense concept the same afternoon I found this page. I typed what I wanted for "Kitchen at One A.M.", ran it twice, then changed only the light and the palette on the second pass. The version I kept went straight into a client deck and saved me a stock-photo search.
My first try for "Interview Room Standoff" came back too polished, more advertising than real photograph. I rewrote the sentence to describe the surface and the actual light in the room, and the third attempt looked like something I could have shot myself. That is the one I still use for ai two person conversation generator mockups.
I use it the way I use a sketchbook: one prompt for "Cockpit Argument Scene", one for "Tavern Corner Whisper", then I pick the half that works and iterate from there. Two of those frames ended up in a package for a client who could not decide between the two directions, and seeing them side by side settled it in a minute.
Yes. State who faces whom, who stands and who sits, and where the light comes from. Skip that and the two bodies tend to float, merge at the shoulders, or both end up looking at the camera.
Occlusion is the hardest thing for these models. Keep hands out of frame, rest them on separate objects, or crop at mid-thigh so there are fewer joints to invent. Two sets of overlapping fingers rarely survive.
Ask for a lens and a practical light: 50mm, shallow depth of field, one window or one lamp, and add no text, no subtitles. Cinematic is a lighting decision, not an adjective stack.
Yes, up to the free allowance the picker shows; paid models start around $5.80 a month. Test a few framings on the free model before you spend anything.
Give each person a small action mid-gesture, such as setting down a cup or pausing mid-sentence, plus one emotion word each. Two neutral faces staring straight ahead is what reads as staged.
