What does Diaform do?
Diaform is a tool that automates customer interviews using an AI agent. Instead of sending out a static survey, you create a set of base questions, and Diaform conducts a voice-based conversation with each respondent. It asks follow-up questions in real-time, probes for deeper meaning when answers are vague, and aims to uncover the 'why' behind user feedback. The result is a collection of insights that feel more like the depth of a one-on-one call, but can be scaled to hundreds or thousands of users.
It works by using a human-like AI voice to conduct interviews directly in a user's web browser, with no login required. What makes it stand out is its ability to adapt dynamically. The AI doesn't just follow a rigid script; it listens to what the user says and pivots the conversation. If someone mentions 'pricing,' it can ask about budget. If they report a bug, it asks for reproduction steps. After the interviews, Diaform provides automated summaries, tags key themes, and analyzes sentiment, so you don't have to sift through thousands of chat transcripts.
This tool is a clear fit for product managers, user researchers, and founders who need qualitative feedback at scale. Real-world use cases include running continuous user research pulses, collecting detailed testimonials post-purchase, conducting churn surveys to understand why customers leave, and gathering targeted onboarding feedback. It's for teams that know the value of customer conversations but lack the time to conduct them all manually.
