The AI survey tool that asks follow-up questions.

Diaform turns static surveys into adaptive AI interviews. When someone writes "it was fine", the AI asks what specifically felt okay, what was missing, and what would have made it great. You get the depth of a customer interview with the reach of a survey link.

An AI survey tool that actually digs into the answer

Most "AI survey tools" help you write questions or summarize results after the fact. The respondent experience is still a static form: same order, same prompts, same shallow open-text answers. Diaform changes the interview itself. The AI reads each answer in real time and decides whether to probe, clarify, or move on.

Someone writes "the checkout was confusing." A static survey logs it and goes to the next question. Diaform asks which part felt confusing, whether there was a step where they almost stopped, and what they expected to happen instead. That is the difference between collecting feedback and understanding what to fix.

The problem with static surveys

Shallow answers kill your open-text data

"Fine", "ok", "idk", "no comment", static surveys invite shallow answers because the form has no way to ask "why". A third of your open-text column is noise.

Branching logic can't cover real responses

However many paths you design, users will say something you didn't plan for. Classic forms either drop the response or funnel it into a generic bucket.

Synthesis is a manual tax

Even when open-text answers are good, someone still has to code them into themes. That's usually the job that gets skipped, and the survey becomes decoration.

What makes Diaform different from other AI survey tools

The AI does not just help you build the survey. It runs the conversation, follows up on weak answers, and turns the response into structured insight.

Follow-up questions in real time

Not a pre-programmed 'please elaborate'. A real follow-up based on what the respondent actually said, different for every answer.

Adaptive without branching logic

You don't design paths. The AI adapts to each response on the fly and steers back to your goals when it has what it needs.

Voice or text

Respondents can speak naturally or type. Voice answers are usually 2-3× longer and more candid, especially for sensitive or emotional topics.

Auto-synthesis

Every response comes back with a summary, sentiment, themes, and question-by-question mapping. Across a survey you get clusters and the quotes worth sharing, no manual coding.

Share one link, anywhere

Drop the link in email, in-app, Slack, or a churn flow. Any device, any browser, no account required.

30+ languages

The AI runs surveys in your respondents' native language and summarizes back to English for your team. Global research, no translators.

How an AI survey with follow-ups works

Use it anywhere you would normally send a form, but let the AI do the probing a human researcher would normally do manually.

  1. 1

    Write your questions + context

    Add the questions you want answered and upload product context so the AI can reference your features, pricing, and roadmap mid-conversation.

  2. 2

    Share one link

    Send via email, embed in-app, drop in Slack, or paste in a churn flow. Every respondent launches their own session.

  3. 3

    AI asks the follow-ups

    Each answer gets a real-time probe if it's vague or interesting. The AI closes gracefully when it has what you asked for.

  4. 4

    Review synthesized results

    Per-response summary, theme tags, and sentiment arrive instantly. Across the survey you get clusters, top quotes, and trend charts.

What teams use AI surveys for

The best use cases are the ones where a normal form gives you one-word answers and a live interview would be too slow to schedule.

Product surveys

Replace your quarterly product survey with a dynamic one. Capture the why behind every rating, not just the score.

Churn and exit surveys

When someone cancels, skip "why are you leaving?" with five checkboxes. Get the real reason, and catch the saveable ones.

Onboarding and activation surveys

Trigger a conversation at key onboarding moments. Find out why a new user stalled before they churn.

Post-purchase feedback

Fire the survey right after checkout. Voice responses capture the emotional bit you can turn into a testimonial.

Customer research pulses

Quick, lightweight studies, validate an idea, test messaging, gather reactions. Answers arrive with depth attached.

Employee and internal surveys

Run engagement or retro surveys with real follow-ups. The AI probes on 'what would you change' so the answers are actionable.

Static surveys vs. AI surveys with follow-ups

The point is not to make a form look like chat. The point is to ask better follow-ups and return analysis your team can act on.

Frequently asked questions

Q

What is an AI survey tool?

An AI survey tool uses an AI model to conduct the survey, not just to analyze the results afterwards. The best AI survey tools read each response in real time and decide whether to ask a follow-up, clarify, or move on, which unlocks the depth of a research interview in a format that feels like a survey.

Q

Can the AI ask follow-up questions inside the survey?

Yes. That is the core difference between Diaform and a traditional form builder. The AI reads each respondent's answer and asks a relevant follow-up when the answer is vague, surprising, emotionally strong, or important to the research goal.

Q

Is this a replacement for Typeform, Google Forms, or SurveyMonkey?

For most use cases, yes, especially anything involving open-ended questions where you want real answers. Diaform also handles structured data (scales, multiple choice) but adds the conversational layer classic form builders can't.

Q

Can respondents answer with their voice?

Yes. Voice input is built in. The AI also speaks back with a human-sounding voice, natural flow, emphasis, and pauses, so the experience feels like a real interview rather than a chatbot.

Q

How much deeper are the responses, really?

In the use cases customers care about most, churn, onboarding, product feedback, respondents give 2-3× longer answers on average, because they're being asked specifically about what they said. Fewer 'fine's, more 'this specific step confused me because X'.

Q

Can I still export structured data?

Yes. Each conversation produces structured fields (question by question) and an auto-generated summary. You can export to CSV or connect to your BI stack for quant analysis.

Q

Does it work on mobile?

Yes. Surveys run in any modern browser on mobile, tablet, or desktop. No app, no download, no signup for respondents.

Q

How many languages does it support?

Diaform supports 30+ languages. The AI survey runs in the respondent's native language and produces summaries in English for your team.
