Yazi marries the comprehensiveness of in-person interviews with the mass distribution scale of WhatsApp surveys.  Personal, in-depth WhatsApp interviews distributed at mass scale.

Surveys Lack Depth.
Interviews Take
Time.

You shouldn’t compromise on either
Yazi provides the depth and context of interviews, but requires far less time, money and human resources.

interviews can't be conducted at scale

  • They take time. 
  • They’re expensive. 
  • The data is difficult to collate, quantify, and analyse.

SURVEYS LACK DEPTH

  • Lack cultural context and human emotion.
  • Limited to shallow insights.
  • Fixed line of questioning.

How Yazi's AI Interviewer works

Launch custom AI WhatsApp interviews to hundreds of people and get results in 7 minutes

Yazi is trained to act as a professional interviewer

This tool enables detailed and interactive research, adjusting questions based on respondent feedback, at a fraction of the usual time and cost.

  • Adaptive questioning: Adjusts questions based on respondent feedback and noticing non-verbal signals
  • Comprehensive insights: Yazi captures the depth of an interview at the scale of a survey.
  • Automated question generation: Questions created from research brief, saving 15-30% of overall project time.

Response features for Participant

Supports 100+ languages in voice and text responses.

Translation

Participant can respond in any 100+ languages. Language barriers can limit participants' ability to express themselves. This feature also saves researchers on translation costs by allowing participants to answer in their preferred language.

Voice note

Participants can choose to respond in text or voice note. Many participants find spelling and typing challenging. Voice notes offer an easier way for them to respond, providing richer context and more accurate data than text alone.

I recently spoke to @Timothy Treagus of Yazi.
Their platform leverages WhatsApp for widespread scalable, autonomous user interviews and surveying.
I tried out Yazi the other day and honestly got that rare feeling that I might’ve just seen the future…

Frequently Asked Question

We have gathered the answers to common queries about how Yazi facilitates revolutionary market research through WhatsApp, alongside a host of other insightful information.

01.

What is an AI-moderated interview on WhatsApp?

An AI-moderated interview is a qualitative research session conducted by artificial intelligence within WhatsApp. Unlike static chatbots that follow fixed scripts, AI interviewers use generative language models to understand participant responses in real-time and ask intelligent, adaptive follow-up questions (probes) to explore deeper motivations, just like human researchers do.

02.

Does the AI interviewer support voice notes and video responses?

Yes. Participants can respond via text, voice notes, or video in WhatsApp AI interviews. When participants send voice notes, the system automatically transcribes the audio, analyzes the content, and generates relevant follow-up questions based on what was said. This creates a seamless, voice-first conversational research experience.

03.

How does AI interviewing on WhatsApp compare to human-moderated interviews?

While human moderation provides deep psychological nuance, it is slow and expensive to scale. AI interviewing allows researchers to conduct hundreds or thousands of in-depth interviews simultaneously—a scale impossible for human moderators. AI interviews bridge the gap between the broad reach of surveys and the qualitative depth of focus groups, though they work best when supplementing rather than replacing human research expertise.

04.

Can WhatsApp AI interviewers conduct interviews in multiple languages?

Yes. AI interview systems can typically conduct conversations in dozens of languages, including local dialects (such as Afrikaans, French, Portuguese, Japanese and Arabic). The systems automatically translate transcripts back into the researcher's preferred language for analysis, breaking down language barriers in global research projects.

05.

How do AI-moderated WhatsApp interviews compare in cost to traditional qualitative research?

AI-moderated interviews are significantly more cost-effective than traditional qualitative methods. Traditional qualitative research involves high recruitment, facility, incentive, and moderator fees per session. AI interviews can reduce these costs by up to 70%, allowing researchers to conduct qualitative projects at quantitative sample sizes and budgets.

06.

What are the advantages of AI interviews over traditional surveys?

Traditional surveys force participants into pre-defined answer choices (A, B, or C). AI interviews allow open-ended exploration where the system can identify when participants give short or vague answers and gently probe for more detail. This captures rich, nuanced insights that standard multiple-choice surveys would miss, while still maintaining the scale advantages of automated data collection.

07.

Can researchers control the questions the AI asks?

Yes. Researchers set the "discussion guide" or core research objectives before launching AI interviews. Most platforms offer hybrid models where specific structured questions are mandatory, while allowing the AI to probe for depth on open-ended responses. Researchers can also set "guardrails" to ensure the AI stays focused on relevant topics.

08.

How do you analyze hundreds of AI interviews?

Yazi uses an automated classification systems that categorize each question by type and each participant answer using tailored category sets. To prevent AI hallucination, the systems typically use number-based category selection rather than generating new text labels, ensuring consistent classification across large datasets. The platforms then generate executive summaries and identify recurring themes automatically, allowing researchers to move from hundreds of transcripts to actionable insights in hours rather than weeks of manual coding.
