Dialogue Passes

I can spot AI-generated dialogue from across the room, and so can every actor I've ever handed pages to. It's grammatical, it's balanced, everyone finishes their sentences, and everyone sounds like the same articulate nobody. Real people interrupt, dodge, repeat themselves, and say "fine" when they mean the opposite. That texture comes from you knowing your characters — it does not come out of ChatGPT or Claude, and this chapter is not going to pretend otherwise.

What the machine can be is the most patient line-reader you've ever worked with. It will read your scene two hundred times without sighing. It will tell you which speech nobody can say in one breath, which exchange states its subtext out loud, and which four lines are doing the work of ten. AI as line-reader, never line-writer. Hold that line and dialogue passes become the fastest part of your rewrite.

The alternatives drill and the table read

Here's the one exception to "never let it write," and it's a controlled burn. When a line is flat and you know it's flat, ask for ten versions — angrier, funnier, shorter, more evasive, in the character's voice as you describe it. Then don't use any of them. The ten alternatives aren't candidates; they're a map of the obvious. Once you've seen the ten lines anyone could write, the eleventh — the one you write yourself, after closing the laptop — comes out sharper, because now you know what it has to beat. Writers have done this with trusted readers for a century; the machine just makes it instant.

The second drill is the table read. Paste a scene and ask the AI to read it aloud — most chat tools can voice it now, and even having it walk through the scene line by line in text works. You're listening for clunk: the sentence that trips, the speech that runs three lines past its point, the exchange where two characters politely take turns instead of colliding. Dialogue is written for the ear, and this is the cheapest way to hear yours before an actor does.

On-the-nose detection and the trim

The most valuable dialogue question I've ever put to an AI is this: "For each character in this scene, what are they hiding — and does the dialogue say it out loud?" That's the on-the-nose detector. When the answer comes back "she's hiding her guilt, and in line 14 she says 'I feel so guilty,'" you've found the exact spot where your scene stopped trusting the audience. The fix — a look, a deflection, a subject change — is yours to write. The machine only points.

Then trim. Dialogue survives on what's cut: the entrance line, the exit line, the second half of any speech that made its point in the first half. Run these drills on every dialogue scene before you call a draft done:

• The alternatives drill — ten AI versions of the weak line, then write the eleventh yourself. The ten define what to beat.
• The table read — have the AI read the scene aloud and flag lines that trip, speeches that run long, rhythms that flatten.
• The subtext check — "what is each character hiding, and does the dialogue say it out loud?" Every yes is a rewrite target.
• The interchangeability test — strip the character names and ask if it can tell who's speaking. If it can't, your voices have merged.
• The trim pass — ask which lines can be cut with the meaning intact, then cut more than it suggests.

Notice that every drill ends with you making the change in your own draft — in Final Draft, in a Fountain file, wherever you write. Never paste the AI's phrasing back into the script. The point of the pass is that the voice on the page stays yours, just tighter.

Your structure holds and your dialogue snaps. Next chapter we zoom back out and put the whole draft on the table: how to get coverage-grade notes from AI before a single human reads it — and why humans still get the last word.
