Comparison
AI interviews vs surveys
A survey records the answer you thought to offer. An AI-moderated interview asks what you did not. Neither replaces the other. This page is about when to use which, with your own customers. Insightful Chat does not recruit participants.

What a survey is good at
A survey asks a fixed list of questions and records a fixed kind of answer: a score, a choice, sometimes a short comment box that most people skip. You can send it to a large list in an afternoon. The result is a count. If 64 people pick “too expensive”, you know that 64 people picked “too expensive”. You do not know whether they meant the price, the value, or a feature they never opened.
That count is the right output when the decision is a number: a benchmark you will compare next quarter, a pulse check that has to stay identical so the trend means something, or a question so small that a conversation would be a waste of someone’s time.
What an AI interview does instead
An AI interview is a conversation with a plan behind it. You write a brief the way you would brief a researcher. Insightful Chat drafts topics, anything you want to show, and the few questions that should be a number or a choice. The participant opens one link, on a phone or a computer, and talks or types. They do not need an account.
The interviewer asks in plain language and follows up when an answer is thin. “Too expensive” can turn into “we weren’t using most of it”. That second sentence is usually the one that tells a team what to fix. The same customer, asked the same opening question, gives you a reason instead of a box.
You still get structure at the end. Each conversation becomes a transcript, a summary, themes across the study, quotes tied back to the turn they came from, and attributes you define, exported as CSV. It is not a transcript you then have to code by hand, and it is not a dashboard of tick boxes.
Side by side
| Question | Survey | AI interview |
|---|---|---|
| What you learn | The option someone picked, or the number they chose. | The reason behind that answer, in their words, including the part you did not think to ask. |
| How many people | As many as you can send it to. Built for hundreds or thousands of responses. | A smaller set. Enough conversations to see a pattern, not a census of every customer. |
| How long it takes them | A minute or two of tapping boxes. | A short conversation, by voice or text. Longer than a survey, shorter than a scheduled call. |
| How fast you can start | As soon as the questions are written. | As soon as the brief is written. Participants open one link. Nobody books a time. |
| Cost per response | Cheap per person, and the analysis is mostly counting. | More per person, because a person is talking. Credits are spent per interview, not per seat. |
| What you do with the answers | Charts of the choices you offered. | A transcript, a summary, themes, quotes tied to the turn they came from, and attributes you can export. |
Credit costs for a text or voice interview are on the pricing page. A survey tool’s price is its own.
When a survey is still the better choice
Use a survey when you need the same question, asked the same way, of a large number of people, so you can compare the count over time. A quarterly benchmark, a one-tap pulse after a release, or a score you have promised a board you will track: those are surveys. An interview would change the question slightly every time, because it follows the person, and that is exactly what you do not want in a trend line.
Use a survey when the only thing you need is the number. If “how likely are you to recommend us” is the whole job, a conversation is overhead. The interesting part of NPS is not the score. It is why a detractor gave it. That is a second step, not a reason to throw out the score.
Use a survey when people will not give you several minutes. A receipt page, a cancellation button, a prompt inside a product that has to stay out of the way: a short form respects that. An interview belongs where someone has already agreed to talk.
When an AI interview fits
Use an interview when the decision depends on a reason: why someone churned, why they bought, where onboarding stalled, what they compared you with. The list of reasons you would have put on a form is the list you already believe. The interview is how you find the one you left off.
It also fits when scheduling a human researcher for every customer is the thing that stops the research from happening. The participant opens a link from an email, from inside the product, or from a QR code. They can speak or type, switch, replay a question, or ask for it another way. You are not on a calendar, and neither are they.
It is a poor fit when you need statistical confidence across a whole market, when the topic needs a human interviewer in the room, or when you do not yet have customers of your own to invite. Insightful Chat does not supply participants, and an AI interviewer is not a substitute for a moderated session with a prototype in someone’s hands.
The useful combination
Many teams already have the survey. Keep it. Send the interview to the people whose answer you do not understand. An NPS survey can keep producing the score. The detractors, or the people who chose “other”, get a link and a conversation about why. A cancellation form can keep the checkbox. The people who cancel get a short interview while the reason is still fresh.
The survey tells you how many. The interview tells you which of those numbers is actually a different problem. You do not have to pick one method for every question you will ever ask.
Try one conversation
The shortest way to judge the difference is to take an interview yourself. It is a real conversation, about two minutes, and nothing you say is tied to your name.
