Reach n=10,000+ across 15+ countries in days, not months. 70-90% completion once a participant starts. Statistical rigour your stakeholders will sign off on.
Large-sample foundational studies. Quotas, weighting, and analysis-ready cuts on day one.
Statistical clustering with descriptors, sizing and ready-to-share segment summaries.
Price-sensitivity meters and conjoint trade-offs rendered natively in WhatsApp Flows.
Weekly or monthly waves with stable panels. Auto-generated wave-on-wave reports.
Three problems traditional online panels can’t fix.
WhatsApp’s a primary channel, not a forgotten inbox. Means you can run lighter recruitment, shorter fielding, and tighter margins on the same incidence rate.
Emerging market respondents. Low-LSM segments. Specific niches by phone number. The audiences your panel partner says “we can try” but never delivers on.
Weighted exports, banner tables, segment cuts. Or pipe responses into your warehouse in real time and run your own models.
15-minute scoping. Bring your last quant brief -
we’ll price it both ways.
Discover why leading agencies and researchers trust Yazi for their data collection needs. Hear directly from our satisfied clients who've experienced the transformative power of our platform.
"The established techniques we had been in field for about three weeks and with Yazi, we were able to create our questionnaire launch and get feedback within a 24-hour cycle... Here you're able to get a very good sense very quickly about what works or what doesn't work or what types of things may need further investigation."
"Yazi really simplified data collection for us, increased our engagement, increased our response rate, and gave us an overall better platform to collect quality data for our clients. Through using the tool, we can see Yazi being leveraged in other research activities such as price collection through OCR, customer satisfaction, customer experience, and mystery shopping."
"Yazi's targeted approach was essential in validating our concept for a project aimed at SMEs. Their efficient data collection and ability to access the right market segment provided us with the crucial insights needed to validate and refine our product strategy, especially in understanding operational, pricing, and competitive dynamics."
"The results Yazi delivered were outstanding. Their platform allowed us to engage with Gen Z on their preferred platform—WhatsApp—and the AI interviewer provided deep insights that we hadn't captured with traditional methods. The real-time feedback and rich qualitative data from voice notes gave us the edge we needed to understand our future customers better. We’re excited to apply these insights to the retailer's marketing strategies."

"Yazi was a game-changer for us! It helped us connect with a typically hard-to-reach audience via WhatsApp, opening up a whole new segment for our research. It was quick, cost-effective, and highly personalised. We received our results in less than 24 hours! Yazi saved us loads of time and empowered us with valuable insights to make informed product development decisions based on a deeper understanding of our audience."
"Yazi's WhatsApp platform has been such an amazing resource for our team to utilise. It granted us swift and direct access to our target market, significantly enhancing our product development process. Tim from the Yazi team was particularly helpful, offering guidance on question design and research methodology. Thanks to Yazi, we were able to refine our marketing strategy, positioning, and communication effectively."
"Working with Yazi, and particularly with Tim, showcased the platform's remarkable flexibility and problem-solving prowess. Tim's foresight and ability to anticipate our project needs were exceptional. Yazi's adaptability was key in managing the dynamic demands of academic research, proving invaluable in my studies."
"Yazi built a table that shows who has completed and who hasn't, allowing us to track progress in real-time, which was a game-changer for us. Yazi’s AI Interviewer exceeded our expectations, delivering the depth and quality of insights we require, but in a much more efficient manner."
We have gathered the answers to common queries about how Yazi facilitates revolutionary market research through WhatsApp, alongside a host of other insightful information.
A WhatsApp diary study is a longitudinal research method where participants document their daily behaviors, experiences, or product usage directly through WhatsApp chat over a period of time. Instead of logging into a separate app or website, participants communicate with researchers (or automated systems) through the messaging app they already use, significantly lowering barriers to participation in qualitative research.
Traditional diary studies often rely on physical journals, email logs, or dedicated research apps that feel like "homework." WhatsApp diary studies feel like natural conversations. They capture data "in the moment" rather than relying on end-of-day recall, resulting in more authentic, immediate, and detailed insights. The familiar WhatsApp interface also reduces participant training time and technical barriers.
Traditional mobile ethnography requires participants to download specific apps and create new accounts, creating significant drop-off. WhatsApp diary studies eliminate this friction entirely since participants already use WhatsApp daily. Additionally, researchers typically ask participants to pin the diary chat to the top of their WhatsApp, keeping it visible and top-of-mind throughout the study period. This results in substantially higher completion rates compared to the 40-55% typical of dedicated research apps.
Yes. WhatsApp diary study platforms can schedule automated "nudges" and triggers that fire at specific times of day or based on participant behavior (e.g., "Don't forget to log your lunch"). Because these appear as standard WhatsApp notifications, they are seen almost immediately, maintaining high compliance throughout multi-day studies.
Participants can submit text, voice notes, photos, and videos directly through WhatsApp. This is ideal for tasks like "show us your pantry," "record your unboxing experience," or "tell us how you feel right now." All media uploads instantly to research dashboards, and voice notes are typically auto-transcribed for analysis.
There is no technical limit to WhatsApp diary study duration. Studies can range from a few days to several weeks or months. For longer studies, platforms typically support engagement strategies like chat pinning and automated incentive tracking to maintain participant motivation throughout extended research periods.
Yes. While diary studies can be fully automated, most WhatsApp research platforms offer "agent takeover" functionality. This allows human researchers to step into the chat, view incoming responses in real-time, and ask follow-up questions or clarify instructions manually when needed.
WhatsApp is designed for stability in low-bandwidth areas. If participants are offline, their diary entries (including photos and videos) are stored locally and uploaded automatically once they reconnect. This makes WhatsApp diary studies ideal for research in areas with spotty internet coverage.
WhatsApp diary study platforms typically provide real-time dashboards that aggregate all participant data. This includes automated transcription of voice/video content, thematic analysis of text responses, and demographic filtering capabilities. Most platforms allow data export to Excel/CSV or can generate presentation-ready summaries automatically.
