No real follow-ups
When a respondent writes "it was fine", Typeform moves on. Your open-text column fills with shallow answers nobody can act on.
Diaform vs Typeform: the AI interviewer vs the static form.
Typeform makes static forms feel friendly. Diaform skips the form entirely, an AI interviewer asks, listens, follows up, and synthesizes. Same one-link distribution, very different depth.

Feature-by-feature comparison
Typeform
Interview format
Diaform runs a real conversation, the AI listens, decides what to probe, and adapts question order to each respondent.
Typeform asks pre-written questions one at a time with optional logic jumps. Polished, but every respondent gets the same script.
Follow-up questions
Pick a probing intensity (1, 3, or 5) and the AI generates follow-ups based on the actual answer it just received.
No AI follow-ups. You can branch on a multiple-choice value, but Typeform never reads an open-text answer and digs deeper.
Voice support
Voice input via Whisper plus a natural ElevenLabs voice for the AI. Voice answers are typically 2-3× longer than typed ones.
Text input only. No voice answers from respondents and no spoken AI-led interviews in the form itself.
Auto-synthesis (sentiment, themes, quotes)
Per-conversation summary, sentiment, confidence score, keywords, and notable quotes generated automatically, no manual coding.
Raw responses export to a spreadsheet. Some recent AI add-ons summarize fields, but coding open-text into themes is on you.
Mid-interview automations
13 topic + 5 sentiment triggers fire actions in flow: alert Slack, capture email, offer a discount code, book a meeting, redirect.
Logic jumps and post-submit integrations exist, but no AI-driven mid-flow actions based on what the respondent is saying.
Branded form polish
Branded subdomain by default and custom domain on Business. Clean, conversational UI tuned for interview depth, not landing-page polish.
Industry-leading form aesthetics, typography, transitions, and theme system that designers love. The polish bar for static forms.

CSV export and HMAC-signed webhooks (3 trial / 5 Pro / 10 Business) feed any stack. Native integrations roadmap is short today.
Hundreds of native integrations, HubSpot, Mailchimp, Salesforce, Zapier, Notion, Google Sheets, built up over a decade.

What each tool actually does
Typeform pioneered the one-question-at-a-time conversational form. It's polished, well integrated, and excellent for structured data capture, signups, lead gen, payments, simple surveys with a bit of branching logic. What it doesn't do is read an answer and decide to probe it.
Diaform is an AI interviewer. The same shareable link, but every respondent has a different conversation: the AI hears "checkout was confusing", asks which step, and surfaces the pricing-page friction you'd never have caught with a checkbox. You get sentiment, themes, and notable quotes generated automatically.
Where static forms hit a ceiling
Branching logic is brittle
Every path you didn't pre-design ends in a generic bucket. Real users say things you didn't plan for, and the form has nowhere to put it.
Synthesis is still your problem
Typeform hands you a spreadsheet. Coding open-text into themes is the job that always gets skipped, and the survey becomes decoration.
Where Diaform pulls ahead
Adaptive AI follow-ups
Pick a probing intensity (1, 3, or 5 follow-ups) and the AI decides per answer whether to dig in or move on.
Voice or text on any device
Respondents can speak, voice answers run 2-3× longer. Whisper input plus an ElevenLabs voice make it feel like a real interview.
Auto-synthesis per response
Each conversation comes back with a summary, sentiment, confidence, keywords, and notable quotes. No manual coding.
Triggered automations
13 topic triggers and 5 sentiment triggers fire actions mid-interview: alert Slack, offer a discount, ask for an email, book a meeting.
Per-project knowledge base
Upload product docs (up to 50k tokens) so the AI can reference your features, pricing, and roadmap inside the conversation.
30+ languages, English summaries
The AI runs interviews in the respondent's native language and reports back to your team in English.
Pick the right tool for the job
When Typeform is the better fit
Reach for Typeform when the questions are fixed and the answer is a number, an email, or a credit card, lead capture, signup forms, payment flows, simple NPS. It also shines as a polished marketing-page embed with deep HubSpot, Mailchimp, and payment-processor integrations where open-ended depth isn't the point.
When Diaform is the better fit
Pick Diaform for churn interviews, onboarding feedback, concept tests, and jobs-to-be-done work, anywhere the answer is a story rather than a checkbox. It's built for SaaS teams that want research-grade qualitative data without booking thirty user calls a week, with sentiment and themes synthesized for you.
Frequently asked questions
Q
Is Diaform a Typeform replacement?
For any flow with open-ended questions, yes. Diaform also handles structured fields (scales, multiple choice), but adds the conversational AI layer Typeform doesn't have. For pure lead-gen or payment forms, Typeform is still a great pick.
Q
How does pricing compare?
Typeform Basic is around $25/mo and Business around $83/mo (annual). Diaform Pro is $89/mo ($74/mo annual) and Business is $149/mo ($124/mo annual), with a 14-day trial that includes 150 conversations.
Q
Can I migrate my Typeform questions into Diaform?
Yes, paste your existing question list in and pick a probing intensity (1, 3, or 5). The AI will run those questions as a conversation instead of a static form.
Q
Does Typeform have AI follow-ups now?
Typeform has added some AI features around generation and analysis, but the form itself still asks fixed questions in sequence. Diaform runs the interview itself, the AI decides what to ask next based on what was just said.
Q
What about embedding inside my product?
Diaform runs on a branded subdomain (acme.diaform.io/c/...) by default and supports a custom domain on Business. One link works in email, in-app, Slack, or QR. Typeform's embed widget is more mature for marketing pages today.
Q
Will my data be used to train AI models?
No. Diaform does not use customer conversation data to train AI models.
