The AI handles follow-ups automatically.

Static forms are a one-way street.

You are trying to understand your customers using tools built for simple data entry. Surveys leave you guessing, and manual interviews don't scale.

The "Dead End" Feedback

The "Dead End" Feedback

If a user tells a standard form "The app is confusing," the form just says "Thanks." You lose the customer, and you learn nothing about how to fix it.

The Missing Context

The Missing Context

Surveys can't ask "Why?" They give you shallow data points (e.g., "NPS is 6") but zero explanation on what features are actually driving that score.

The "Zoom" Cap

The "Zoom" Cap

Manual interviews are gold, but you can't schedule 500 of them. You end up with great insights from 5 people, and silence from the other 495.

Diaform closes the loop.

It interviews your users, digs for the root cause, and takes action instantly. Get the quality of a Zoom call with the reach of a survey.

Diaform is like cloning your best user researcher

Diaform conducts hundreds of interviews simultaneously. It never gets tired, never forgets to ask "why", and gives you structured data instantly.

Probes for the 'Why'

Probes for the 'Why'

Static forms accept vague answers. Diaform spots them and asks intelligent follow-up questions to uncover the root cause.

Dynamic & Adaptive

Dynamic & Adaptive

No complex logic trees. If a user mentions pricing, the AI pivots to ask about budget. If they mention bugs, it asks for reproduction steps.

Zero-Friction Launch

Zero-Friction Launch

No login walls or scheduling links. Your audience can start the interview instantly in their browser, increasing completion rates.

Analysis, not just Transcripts

Analysis, not just Transcripts

You don't have time to read 1,000 messages. Diaform auto-summarizes every interview and tags key themes like 'Pricing' or 'UX' for you.

The highest-converting forms feel like conversations

Diaform uses human-like voice AI to keep users engaged and collect deeper feedback than any text box ever could.

AI Interviewer

State-of-the-art voices

Modern voices with natural flow, emphasis, and pauses - it sounds like a real interviewer, not a chatbot.

Fast, gapless playback

Audio starts instantly. We the audio so replies feel responsive and conversational.

Skyrocket your completion rates

The immersive audio-sync feels like a real 1:1 interview, keeping users hooked and delivering significantly higher conversion rates than static forms.

Use cases where Diaform shines

Drop the AI interviewer into the exact moment that matters—whether you need discovery insight, proof to publish, or a churn rescue signal.

Customer interviews

Run continuous discovery on autopilot. The AI interviewer matches your tone, asks open-ended questions, and follows up until it gets the full story — so you get the depth of a 30-minute call from a 3-minute chat.

  • Runs 24/7 — no scheduling, no no-shows

  • Every response gets an AI summary with key themes

  • 10x more responses than manual interviews

AI interviewer

Tell me about the moment you realized you needed this. What was going on?

Customer

Honestly, I was buried. Spending 3+ hours every week just copying user feedback from emails into spreadsheets. My manager kept asking for insights and I had... nothing organized.

AI interviewer

That sounds frustrating. When you first tried it, what surprised you most?

Post-purchase stories & testimonials

Trigger a conversation right after checkout while the experience is fresh. The AI draws out specific moments and emotions — turning a generic "great product" into a publishable quote.

  • Captures the story behind the purchase, not just a star rating

  • AI extracts the best quote automatically

  • Collect 5x more testimonials without asking your team to chase them

AI interviewer

Congrats on your purchase! What was the deciding factor for you?

Customer

I'd been comparing tools for weeks. Yours was the only one that let me run interviews without scheduling calls. That was the dealbreaker.

AI interviewer

Love that. If you had to describe the experience to a colleague in one sentence, what would you say?

Customer

"It replaced three hours of weekly user calls with a link I send once."

Extracted testimonial

“It replaced three hours of weekly user calls with a link I send once.”

Churn surveys

When someone cancels, a one-question form gets you a shrug. An AI conversation gets you the real reason — and sometimes saves the customer before they leave.

  • Empathetic follow-ups that don’t feel like an interrogation

  • Surfaces patterns like pricing confusion vs. missing features

  • Avg. 3x longer responses than static exit surveys

AI interviewer

We're sorry to see you go. Can you walk me through what led to this decision?

Customer

It's not that the product is bad — I just couldn't figure out how to connect it with our CRM. I spent a whole afternoon on it and gave up.

AI interviewer

That's really helpful to know. If we had a guided setup for CRM integrations, would that have changed things?

Customer

Honestly, yeah. If I could get that working I'd probably stick around.

Integration blockerSaveable

Onboarding feedback

Drop a conversation at key milestones — first login, first project created, day 7. Catch friction before it becomes churn and give your CS team specific things to fix.

  • Trigger at any onboarding milestone via link

  • Spots UX confusion, missing docs, and integration blockers

  • Summaries go straight to Slack so your team acts fast

AI interviewer

You just created your first project — nice! How did the setup feel?

New user

Pretty smooth actually. I got stuck for a sec trying to add my knowledge base — it wasn't clear I needed to save the project first.

AI interviewer

Good catch. Anything else that felt confusing or took longer than expected?

New user

I wish the preview showed how it looks on mobile. I almost published without checking.

AI summary

Two UX friction points: knowledge-base upload requires save first (confusing), and mobile preview is missing from the editor.

User research pulses

Need to validate a feature idea or test new messaging? Launch a quick study in minutes, collect 50+ responses by end of week, and get an AI-generated brief with the top themes.

  • From question to insight in days, not weeks

  • No need to hire a researcher for lightweight studies

  • Keyword and sentiment analysis built in

AI interviewer

We're thinking about adding team collaboration features. How do you currently share insights with your team?

Participant

Right now I just screenshot the dashboard and drop it in Slack. It works but my team never reads the full context.

AI interviewer

What would make it easier for your team to actually use the insights?

Participant

If I could share a live link to a filtered view — like 'here's everything about onboarding friction this week' — they'd actually look at it.

Why teams switch from form builders and clunky chat widgets

Rigid forms and generic chatbots weren't built for real conversations. Diaform was.

We replaced our exit survey with Diaform and the difference was night and day. Instead of one-word answers, we started getting paragraphs of context. Our product team now has 3x more actionable feedback to work with.

The AI follow-up questions are surprisingly good. It picks up on subtle cues in user responses and digs deeper in exactly the way I would in a live interview. It's like having a junior researcher who never gets tired.

I set it up in under five minutes and had our first batch of insights by the next morning. No scheduling, no Zoom fatigue, just real customer feedback showing up in my inbox. It's the fastest path from question to insight I've found.

Frequently asked questions

How fast can I launch my first interview?

You can create an interview, set it up with your questions and context in minutes. No engineering work or complex setup steps required.

Can the AI handle follow-up questions automatically?

Yes. Our model understands the context you provide, probes for clarity, and only advances once it has the detail you need.

Do I need to manage transcripts manually?

No. Conversations are summarized automatically the moment a session ends. You’ll have full data to review inside the dashboard.

Is voice input supported out of the box?

Yes. Customers can speak or type their responses.

Can I upgrade as usage grows?

Absolutely. Start on the Free plan and unlock more conversations, questions, seats, and advanced analytics when you move to Pro.

What counts as an AI conversation in the subscription plan?

A new conversation is counted the moment someone opens your interview link and starts a new conversation. Everything that follows—clarifications, retries, summaries—stays within that single session. Free includes 20 sessions per month.

Can I add knowledge so the feedback assistant knows what it is doing?

Yes. Each interview has a Knowledge section where you can add product briefs, docs, or FAQs. The Free plan allows up 20k tokens total, so the assistant can stay on-message and reference the right facts mid-conversation.

What is an AI interview?

Inside Diaform an interview is a scripted, AI-powered interviewer that asks your questions, follows up intelligently, enforces the conversation flow (next question, end conversation, etc.), and saves transcripts plus summaries to your dashboard.

How is Diaform different to a Google Form or similar?

Forms collect static answers; Diaform runs a live interview. The AI can clarify vague inputs, accept voice replies, adapt questions on the fly, and auto-summarize the full exchange so you spend less time cleaning spreadsheets and more time acting on insights.

Do you use my data to train AI models?

No, we do not use your data to train AI models, we respect your privacy. Your conversations and insights remain private and secure.

How do I control the feedback collection interview?

From the interview editor you decide the exact question list and knowledge sources. You can pause or archive any interview instantly, so nothing goes live without your approval.

How do I start collecting feedback?

Once an interview is published, copy its share link (e.g. https://yourbrand.diaform.io/c/...). Send the link via email, drop it in-app, or embed it on your site and every visitor will launch a new tracked conversation.

Ready to upgrade your feedback loop?

Stop guessing why users leave. Start an automated interviewer in seconds and get the deep insights of a Zoom call at the scale of a survey.
