I Rehearse Every Hard Conversation With AI First. Here’s the Prompt.

Two years ago, I walked into a salary conversation I’d been rehearsing in my head for six weeks.

I had numbers ready. Market data, comparable offers, the value I’d delivered. I had my opening line down to the comma.

I sat down. My manager smiled and said: “So, how are you feeling about the year overall?”

My entire script collapsed.

I’d practiced a version where she opened with a question about money. She opened with a question about me. I fumbled, rambled, ended up talking about a project that went well - and never actually mentioned the raise I’d come to ask for.

I walked out and realized something I’d been avoiding: rehearsing in your own head isn’t rehearsal. It’s daydreaming. You imagine the other person saying what you’ve already decided they’ll say. You never get pushed. You never get surprised. So when the real conversation goes off-script in the first ten seconds, you have nothing.

Now I rehearse with AI before any conversation that actually matters. Salary chats. Performance reviews. Co-founder disagreements. The “I think we need to part ways” conversation with a contractor. The hard email I don’t want to write.

Here’s the system. One prompt does most of the work.

Why Your Head Is a Bad Practice Partner

When you rehearse alone, you control both sides. You give yourself the perfect cues. You imagine the other person slightly off-balance, slightly persuadable, slightly more reasonable than they actually are.

It’s the same reason you can’t edit your own writing well. The brain that wrote the line is the brain reading it.

An AI rehearsal partner has one specific superpower: it doesn’t care if you feel good after the conversation. It will push back, ask the question you don’t want to answer, and stay in character even when you’re floundering.

That’s not a feature you can get from a friend. Friends, even great ones, soften the punches.

The Hero Prompt: The Rehearsal Partner

This is the one. Paste it before any conversation that matters:

Prompt - The Rehearsal Partner

“I’m about to have a difficult conversation. I need you to play the other person and push back honestly so I can stress-test what I want to say. Don’t be a coach. Don’t break character to give me advice. Just be them.

Who you’re playing: [their role / relationship to me - manager, co-founder, employee, partner, etc.]

How they tend to think and argue: [2-3 lines. Direct or evasive? Defensive? Numbers-driven or feelings-driven? Ask a lot of questions or shut things down?]

What I think they want from this conversation: [your best guess]

What I want from it: [your goal]

Rules of the rehearsal:

1. Stay in character. Always.
2. Push back when I’m vague, evasive, or weak. Ask the uncomfortable follow-up.
3. Don’t make it easy. If the real version of this person would resist, you resist.
4. One turn at a time. Wait for my response before continuing.

Here’s my opening line:

[your actual opening line - the words, not a description of them]”

That’s the engine. Five or six exchanges in, you’ll start to feel the spots where your script has holes.

Two things to get right:

Describe the role, not the person. Tell it your manager “tends to get defensive when budget comes up and likes to redirect to long-term plans.” Don’t paste her name, her actual messages, or personal details about her. You’re rehearsing against a type, not building a digital version of someone. That’s both more ethical and, weirdly, more useful - because you’re training for the pattern, not the person.

Use your actual opening line. Not a description of what you’ll say. The words. Half the value is hearing your opening out loud (in text) before you say it for real. You’ll feel which phrases don’t fit before the AI even responds.

Prompt 2: The Debrief

After 5-6 back-and-forth turns, stop the roleplay and paste this:

Prompt - Step Out of Character

“Now step out of character. Be honest:

1. What was the weakest moment in what I said?
2. What did I dodge?
3. If you were actually the other person, what would you walk away believing about me?”

Number 3 is the one that hits hardest. The conversation isn’t only about what you say - it’s about what they think of you afterward. Sometimes you “win” the rehearsal but leave the AI with an impression you didn’t want to leave.

I had a rehearsal once where I got every line right and the debrief came back:

“You sound prepared, but you also sound rehearsed. The other person will sense it and assume you’re working from a script. You might come across as not really listening.”

I rewrote my whole approach. Talked less. Asked more.

Prompt 3: The Curveball

The last move before you close the chat:

Prompt - The Curveball

“What’s the one thing the other person could say that would completely throw me off - the sentence I haven’t prepared for? Write the line exactly as they’d say it. Then help me prepare two responses: one if it catches me off guard, and one if I have time to think.”

The curveball isn’t paranoia. It’s preparing for the actual shape of real conversations - which is that one sentence always lands you didn’t expect.

For my salary chat, the curveball the AI handed me was: “Honestly, the budget is what it is this quarter. Why is this conversation happening now?”

I would have flinched. Instead, I had two responses ready. We had a real talk.

What a Real Rehearsal Looks Like

Here’s a snippet from a rehearsal I ran before giving difficult feedback to someone on my team:

Me: “I wanted to talk about how the launch went last week. I think there’s some stuff we should reflect on.”

AI (as my report): “Sure. What stuff specifically? Because honestly I felt like it went pretty well given the timeline.”

Me: “Right, the timeline was tight. But I think there were some misses on the QA side that we should look at.”

AI: “Misses, or one specific thing? Because if we’re going to do a post-mortem I’d rather you just tell me what you think I got wrong.”

That second response was a slap. I’d been hiding behind soft, vague language - “some misses,” “stuff to look at” - because I was uncomfortable. The AI called it out in two lines.

By the time the real conversation happened, I knew exactly what specific thing I wanted to name, and exactly why I’d been avoiding naming it.

The conversation took twelve minutes. The old way, it would have taken an hour and ended in confusion.

Three Ways People Get This Wrong

1. Asking the AI to play your actual person, by name. Don’t. It’s a little weird, and more importantly it makes the rehearsal worse - you’ll subconsciously argue with the simulation instead of preparing for the real conversation. Describe the type. Stay anonymous.

2. Rehearsing until you “win.” You’re not trying to come out on top of the rehearsal. You’re trying to find the seams in your own thinking. If the AI gives up too easily, push it harder. If you give up too easily, that’s the data.

3. Skipping the debrief. The roleplay is the fun part. The debrief is the part that actually changes how the real conversation goes. Do both, every time.

One Honest Note

For the truly heavy ones - losing a job, ending a long relationship, a conversation about someone’s health, a rupture with a parent - AI rehearsal helps. But it isn’t enough. Pair it with one person who knows you and the situation. A friend, a therapist, a mentor.

The AI helps you find the words. A real person helps you carry them.

The Conversation You’re Avoiding

If you’re reading this, there’s a conversation in your head right now that you’ve been pushing to next week for a month. The salary one. The “we need to talk about how the project is going” one. The “I think we want different things” one.

Open a new chat. Paste the rehearsal prompt. Spend ten minutes there before you spend it in your head one more time.

Then come back and tell me one thing: what did the AI catch that your inner rehearsal had been letting you skip?

That answer is usually the whole reason you’ve been avoiding the conversation in the first place.
