“I check my balance maybe four times a day. It’s not because I think money disappeared — it’s the feeling that if I look I’m in control.”

Anxiety / control “…the feeling that if I look I’m in control.”

“My friends laugh at me but I’d rather check and feel calm than ignore it and panic at month-end.”

Studies you can run

Qual at scale. Without sacrificing depth.

IDIs

In-depth interviews

Field 50–500 IDIs in a week with adaptive AI moderation. Human takeover whenever you want.

Diary

Longitudinal diaries

7-day, 30-day or 90-day. Photos, voice, location — captured in the moment, themed live.

Ethnography

Digital ethnography

“Day-in-the-life” at scale — n=100 instead of n=8. Same depth, 1/5 the budget.

Hybrid

Quant-qual hybrid

Run a survey of n=2,000 with embedded open-text follow-ups on every response. Themed automatically.

Why qual researchers stop scheduling Zooms.

Three pieces of the qual workflow Yazi quietly deletes.

01 · Recruitment that doesn’t take three weeks

If you have phone numbers, you have fieldwork.

Send WhatsApp invites direct to your panel, your client’s CRM, or Yazi’s recruited audience. Most studies field within 48 hours of brief sign-off.

02 · Transcripts in any language

No more outsourced transcription tickets.

Voice notes auto-transcribed in 100+ languages with original-language + English side-by-side. Speaker turns, timestamps, ready for client debrief.

03 · Coding that proposes, you approve

AI suggests codes. You stay in control.

Themes propose themselves as interviews come in. Accept, reject or rename — every code traces back to the original quote. Auditable, not magical.

Robin Nixon

Managing Director, Greenfields Research

"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."

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."

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 a WhatsApp diary study?

∨

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.

02.

What is the difference between a WhatsApp diary study and a traditional diary study?

∨

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.

03.

Why do WhatsApp diary studies have higher completion rates than app-based tools?

∨

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.

04.

Can you send automated reminders in WhatsApp diary studies?

∨

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.

05

What types of media can participants submit in WhatsApp diary 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.

06

How long can a WhatsApp diary study run?

∨

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.

07.

Can researchers intervene or probe participants during a live WhatsApp diary study?

∨

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.

08.

How does WhatsApp handle offline or low-data environments for diary studies?

∨

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.

09.

What kind of reporting do you get from a WhatsApp diary study?

∨

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.
