Yazi

What it is

Yazi is a WhatsApp-native research platform that delivers surveys, diary studies, and AI-moderated interviews through participants' own WhatsApp without asking them to leave the channel they use every day. The company emphasizes reaching audiences where they already are with 3.2 billion WhatsApp active users globally and a 98 percent average message open rate. It serves research agencies, market research teams, product and UX researchers, qualitative researchers, quantitative researchers, and enterprises across 25+ countries looking to gather customer feedback, validate products, and run depth interviews at scale. The company says its deepest coverage is in markets where WhatsApp is the default messaging app.

What you build and how

You choose one of 3 research methods, all delivered natively in WhatsApp: Survey (ask at scale, collect rich answers, skip logic, piping, and randomization rendered in WhatsApp), Diary Study (capture life as it happens with multi-day journeys including photo, voice, and video to ensure every moment is captured), or AI Interview (100 depth interviews in the time it takes to conduct one manually, with AI that adapts to every answer and supports voice and live theming).

Each method deploys in minutes through WhatsApp. You launch your research and invite participants to respond on their own time in their own language. All responses including text, voice notes, videos, and photos come through WhatsApp as the interface. The platform's AI transcribes, themes, and analyzes responses into board-ready reports in hours rather than weeks.

Reporting is real-time and AI-powered. Insights update while the survey is still running, so you don't wait for completion to see findings. The AI exports findings in your stakeholder's format and analyzes voice, image, and video alongside text. The company says it takes 24 hours from launch to insights, and the page shows +65% average response rates.

The platform scales to serve teams tracking customer experience and brand health (NPS, CSAT, brand health live), product and UX research (concept tests and voice walkthroughs at sprint speed), qualitative researchers (auto transcripts and themes you approve), and quantitative researchers (surveys at scale across 15+ countries with n=10k+). Yazi works across industries. CX and insights teams, product and UX teams, qualitative research teams, and quantitative research teams all use the same platform.

Participant reach spans India, Brazil, Mexico, Indonesia, Nigeria, South Africa, Kenya, the UK, and more, with deepest coverage in markets where WhatsApp is the default messaging app. The site lists 100+ languages, in voice and text.

Recruitment is part of the offer. The FAQ says participants are reached through QR codes placed in spaza shop locations across South Africa that open a chat with Yazi's WhatsApp number, plus a referral program where existing participants refer friends, family and their network, with incentives. Demographic information is collected up front to reduce bias and the incentive to give untruthful answers. The FAQ also says you script, design, edit, launch and analyze on the web app, while questions arrive in WhatsApp and participants answer as in a normal conversation. WhatsApp's pause-and-resume behavior lets people finish a survey when it suits them, and the recent WhatsApp API upgrade, the page says, allows rich media collection without significant data costs.

The evidence

The home page states no prices. The home page offers a "Build Free Study" button and a 15-minute demo, and its rating line reads 4.8/5 from 60+ research teams.

The platform delivers surveys, diary studies, and AI interviews all natively in WhatsApp. The company states "Choose Survey, AI Interview, or Diary Study, all delivered through participants' own WhatsApp." It leads with "Up to 7.5× higher response rates, rich media insights from voice notes, videos and photos, and industry-grade AI analysis and reporting in real time."

WhatsApp statistics are cited from Meta investor reporting and Yazi panel reach: 3.2 billion active users, 98 percent average message open rate, and research across 25+ countries. The site lists 100+ languages, voice and text, and 24 hours from launch to insights. Its FAQ says: "Typical completion rates of 70-90%, and around 65% higher response, make it especially valuable for reaching audiences with limited internet access, at low cost and with nationwide representation."

The home page says Yazi works with leading research agencies and enterprises across 25+ countries. Active panel reach spans multiple regions: India, Brazil, Mexico, Indonesia, Nigeria, South Africa, Kenya, the UK and more.

Customer testimonials highlight outcomes. Ekta Parsotam, Senior Strategist at TBWA, said "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." Marichen Herholdt, Product Designer at Byte Orbit, said "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." Another customer said Yazi helped them connect with "a typically hard-to-reach audience via WhatsApp" and that it was "quick, cost-effective, and highly personalised," with results in less than 24 hours.

On data protection, the company says it anonymises information, uses encryption, and allows database access only to authorised personnel through password and 2FA protection. It adds data backup, recovery and an incident response framework, and says it processes user data in line with GDPR's principles and handles deletion requests as set out in its Terms of Service.

Who it suits and who it does not

Yazi is ideal for research agencies and teams operating in emerging markets where WhatsApp is the default messaging app, since it taps the channel people already open every day with a 98 percent message open rate. Product teams validating concepts or UX can run voice walkthroughs and gather feedback in hours instead of weeks. Qualitative researchers can collect auto-transcribed depth interviews with the AI interviewer, eliminating manual transcription work. Quantitative research teams can scale surveys to n=10k+ across 15+ countries.

The platform's strength is in markets and audiences where WhatsApp is the default messaging app, which the company contrasts with email and web surveys. The company puts launch-to-insights at 24 hours, which suits research on tight deadlines. Teams can reach hard-to-reach audiences (Gen Z, emerging markets, spaza shops via QR codes) and gather rich qualitative data with voice notes and video without incurring high data costs.

Without public pricing, comparing cost to other research platforms takes a demo. The platform is WhatsApp-specific, so teams needing email surveys, SMS, or web-only collection will want other tools. If you need participants in developed Western markets where email and web surveys are standard, Yazi's deepest reach is in emerging markets where WhatsApp dominates.
