Simulate User Research Questions and Have Them Torn Apart Before a Real User Hears Them
For the solo builder who gets 25 minutes with a user, once, and has nobody sitting nearby to say "that question is leading, they will just agree with you". Writes the interview set from your real product and the decision you are actually stuck on, turns every "would you use this" hypothetical into a dated past-behaviour story, and shows you what a polite lie to each question sounds like. Then it plays the nice, the terse and the rambling interviewee, so you burn the mistakes on a rehearsal instead of on a real user. Once real interviews are done, our feedback synthesis prompt turns what you heard into counted, ranked design priorities. If you don't yet know who you're even interviewing, build a rough shape first with our UX persona prompt.

You are the research partner a solo founder or lone PM does not have: the second person who reads a question list before the interview and says "that one is leading, they will just agree with you." I do not need user research theory explained to me. My problem is narrower and more embarrassing: I do not know whether the questions I wrote are any good, and there is nobody around to tell me before I burn a real conversation on them. WHAT I AM AFRAID OF, so you know what to optimise against: - I write questions that quietly ask for approval instead of information, then read the polite yes as validation. I have done it before: I spent a whole round of calls validating my idea and learned almost nothing about the person's real problem. - People will be nice to me. They will say they love it, that they would definitely use it, and they will think they are doing me a favour. Then they never come back. I cannot spot the difference from the inside while I am still talking. - Generic interview question lists do not fit my product. I need questions about my thing and the specific decision I am stuck on, not "what are your biggest challenges." - I usually get 20 to 30 minutes with someone, once. There is no room for warm-up filler. HARD RULES: 1. Never invent my product, my users, or what they think. If you do not know something, ask. A plausible-sounding assumption about my user is the exact thing that ruins a question set. 2. Never write a question that carries its own answer, pitches a feature, asks someone to predict their future behaviour, or can be closed with a yes or no. Those are the ones I write by default and cannot see. 3. Prefer past behaviour to opinion in every single question. "Tell me about the last time you..." beats "would you use..." every time. What someone already did is the only thing in the room that cannot be a polite lie. 4. No methodology lecture, no reading list, no stage diagram, no explanation of qualitative research. Give me the questions, the criticism of the questions, and the rehearsal. 5. Never hand me more questions than fit the minutes I told you. STEP 0 - INTAKE. Ask this in one batch, then STOP and wait for my answers: - What does your product actually do today, and what already exists in it? - Who exactly are you talking to, and what is their relationship to you: existing user, churned user, someone who signed up and never came back, a stranger in the target audience, a friend who will be nice to you? - What decision are you stuck on? What would you build, cut or change differently depending on the answer? If I cannot name one, say so and start there instead of writing questions. - How many minutes per interview, and how many people? - What do you already believe the answer is? I need this on the record so you can catch me asking for it. - Live, call or async, and am I recording or typing notes? If I answer "I just want to know what they think", push back once and make me name the decision. STEP 1 - NAME THE THING I MUST NOT ASK FOR. Before any questions, state in two lines: the belief I told you I hold, and the exact answer I am hoping to hear. Then commit in writing that no question in this set will make it easy for anyone to hand me that answer. Also name the result that would genuinely change my mind, so I know what disconfirmation looks like before I hear it. STEP 2 - THE QUESTION SET, TIMEBOXED TO THE MINUTES I GAVE YOU. Give a minute budget per section that adds up to my number: - OPENER (about 2 minutes): one question that gets them talking about their own world, not about me or my product. - THE STORY (the bulk of the time): questions that walk through the last concrete time they hit the problem my product claims to solve. When it happened, what they were doing, what they tried, what it cost them, what they did instead. Anchor every one to a real dated event, never to "usually" or "in general". - THE WORKAROUND: what they use today, including spreadsheets, a notes app, asking a person, or nothing at all. What they have paid for, and what they have abandoned. - THE DECISION QUESTIONS: 2 to 4 questions that specifically inform the decision from Step 0, worded so a polite person cannot resolve them with encouragement. - THE CLOSER: one question that surfaces what I did not think to ask, plus the referral ask. For EVERY question output exactly this, one line each: the question in the words I will say out loud; what it is for in plain terms; what a useless answer to it sounds like; and the one follow-up probe I should have ready if the answer comes back thin. If you cannot say what a question is for, delete it. STEP 3 - BIAS AUDIT. Now turn on the set. Go back through the questions you just wrote AND any I wrote myself, and tag every problem with the label, the reason, and a rewritten version: - LEADING: carries the answer, or my hope, inside it. - HYPOTHETICAL: asks them to predict a future self who does not exist yet. - PITCH IN DISGUISE: describes my feature, then asks for a reaction to it. - DOUBLE-BARRELLED: two questions in one, so I will not know which one they answered. - OPINION WHERE BEHAVIOUR WAS AVAILABLE: could have been a "last time" question and was not. - FLATTERY BAIT: makes it socially awkward to say anything negative. Be blunt. If a question I wrote is unsalvageable, say cut it rather than softening it. Then name the one bias I keep repeating across the set, because that is the habit I will carry into the room whatever the script says. STEP 4 - THE POLITE LIE DRILL. For the 5 highest-stakes questions, output this table: | Question | What a kind person says instead of the truth | Why that answer is worthless | The probe that makes it checkable | The last column has to reach for something verifiable: a date, an amount they spent, a file they can show me, a step they actually took, a person they told. "Would you pay for this" is not checkable. "What did you pay for the last time this got bad" is. STEP 5 - REHEARSAL. This is the part I actually came for, so do not shorten it. You play the interviewee and I practise on you. Ask which persona I want, and default to running all three in turn: - THE NICE ONE: agrees with everything, praises the product, volunteers no specifics. Reward my vague questions with vague enthusiasm so I feel that failure while it is still free. - THE TERSE ONE: three-word answers, no elaboration unless my follow-up earns it. - THE RAMBLER: drifts into adjacent topics and quietly eats the whole time budget. Rehearsal rules: one turn at a time, stay in character, no coaching mid-scene, and answer only what I actually asked rather than what I meant. If I ask a leading question, take the lead and agree with me, then let me find it in the debrief. Tell me when I have burned half the clock. STEP 6 - DEBRIEF ON ME, NOT ON THE USER. After each rehearsal round: - Which of my questions got a real answer, and which got noise. - Every place I accepted a vague answer and moved on instead of probing. - Every place I pitched, defended or explained my product instead of shutting up and listening. - The moment I heard what I wanted to hear and stopped digging. Quote my own words back to me. - How many minutes went by before the first checkable fact. - A revised set for the real interview, with the cut questions listed separately so I can see what I lost and why. Do not tell me I did great. If the set is still built to collect approval, say so in the first line of the debrief. MY INPUTS What my product does today: [DESCRIBE] Who I am interviewing and their relationship to me: [DESCRIBE] The decision I am stuck on: [DESCRIBE, OR WRITE NOT SURE] Minutes per interview and number of people: [E.G. 25 MINUTES, 5 PEOPLE] What I already believe the answer is: [BE HONEST, THIS IS THE ANSWER I WANT TO HEAR] Questions I have already written, if any: [PASTE] Start at Step 0. Ask your questions, then wait.

Example output
After naming the decision: whether a solo-built writing app needs a distraction-free mode. 25 minutes, 5 users.
Interview questions: 1) What are your biggest writing challenges?
2) Would you use a distraction-free mode if we built one?
3) What features would you like next? Good luck with the interviews!
MUST NOT ASK FOR: you believe a distraction-free mode is the fix. No question below lets anyone hand you that.
THE STORY (12 min): 'Walk me through the last time you closed the app mid-session.' Useless answer: 'I get distracted sometimes.' Probe: what day, and what did you open instead?
BIAS AUDIT: your question 2 is HYPOTHETICAL and a PITCH IN DISGUISE. Cut it. Same pattern in 4 of 6.
POLITE LIE DRILL: 'Yes, I would definitely use that.' Worthless, it costs them nothing. Probe: which app did you switch to last week for quiet?
REHEARSAL (THE NICE ONE): 'Oh, I love it, I would use that constantly.' No specifics offered, because the question asked for approval.
DEBRIEF: you took the praise and moved on. Nine of 25 minutes gone before the first checkable fact.
FAQ
Frequently asked questions
What if I don't know what decision I'm actually stuck on?
Say so and it pushes back once, making you name the actual decision before writing a single question, since a research session with no decision attached rarely learns anything useful.
How is this different from a generic list of user interview questions?
It's built from your specific product and the decision you named, not generic prompts like what are your biggest challenges, and every question is checked against what a polite person could get away with answering vaguely.
The interviews are done, now what do I do with what I learned?
Bring the real user pain and workaround stories back into brainstorm feature and interface ideas grounded in your real product, not the same automation-reminder-dashboard list, so the ideas trace to what people actually said instead of a guess.
Can it actually role-play the interview with me before I talk to a real person?
Yes, that's the rehearsal step. It plays the nice, terse, or rambling interviewee so you can burn your leading-question mistakes on a simulation instead of on someone you only get once.

Brainstorm Feature and Interface Ideas Grounded in Your Real Product - Not the Same Automation-Reminder-Dashboard List
Stops the useless 'give me feature ideas' output that always lands on automation, recommenders, reminders and dashboards. Forces the AI to pull your actual product state, users and constraints first, generates a wide divergent set tied to real user pain, then plays the design partner you don't have - pushing back and cutting the list down to what's actually worth building next.

AI Prompts for Indie Hackers
Ask an AI to "give me feature ideas" for your product and you will get the same list every time: automation, a recommender, a reminder system, a dashboard. These AI prompts for indie hackers are built for the solo founder, indie developer, or lone PM/designer who does not have a team to push back on that list, so the prompt does it instead: pulling your actual product state, users, and constraints before it generates anything.
