The problem: 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
How was your experience?
I didn't like the app.
Any other comments?
No.
✓ Thanks for your feedback!
A user tells your form "The app is confusing." The form says "Thanks." You lose the customer and learn nothing.
The Unpredictable User
Q1: Experience?
├─ “good” → Q2a
├─ “bad” → Q2b
├─ “pricing” → Q3a
├─ “bugs” → Q3b
├─ “slow” → Q3c
├─ “cancel” → Q3d
├─ “competitor” → Q3e
And you're still not even close.
Your user just told you exactly why their team won't buy - but your form doesn't have a branch for that. Real conversations go off-script. Forms can't. AI can.

Manual interviews are gold, but you can't schedule 500 of them. Great insights from 5 people, silence from the other 495.
Forms are flat. Conversations have depth.
Traditional feedback tools give you a rigid, one-dimensional surface. Diaform transforms that into a rich landscape of insight — where every response adds depth and every follow-up reveals more.
Diaform in action
You define questions. The AI conducts a natural voice interview - probing deeper when answers are vague, just like a real researcher.

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’
Static forms accept vague answers. Diaform spots them and asks intelligent follow-up questions to uncover the root cause.
It was fine I guess
Interesting - what part felt just okay? Was there something you wished worked differently?
Actually yeah, the pricing page confused me. I almost left.
Dynamic & Adaptive
No complex logic trees. The AI pivots based on what users actually say.
User mentions “pricing”
Asks about budget
User mentions “bugs”
Asks for repro steps
User sounds happy
Asks for testimonial

Why teams switch from form builders and clunky chat widgets
Rigid forms and generic chatbots weren't built for real conversations. Diaform was.
Built for product teams
Created by SaaS founders who were tired of expensive, rigid feedback tools. Diaform slots right into modern product workflows.
Purpose-built UI
Clean interface to make sure users stay focused on the topic.
Dynamic interviews, not rigid scripts
The AI intelligently adapts to each response. No flowcharts, no branching logic, no hours of setup.
We built Diaform because we needed a smarter way to listen to users. Forms felt robotic and interviews didn't scale. Now the interviews happen on autopilot while we can focus on building.
Run interviews in 32+ languages without extra setup.
Diaform mirrors tone, follows up naturally, and summarizes every conversation in the target language - no prompt juggling or manual translations required.

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.
