With Blix, researchers can code open-ended survey responses in minutes instead of days, turning thousands of verbatim responses into clear, quantified insights. The platform helps teams analyze customer feedback, brand tracking studies, concept tests, NPS surveys, employee feedback, and other open-text survey data quickly and easily, without sacrificing professional coding quality.
Blix is designed to support the way market research teams actually work. Upload your survey data, generate a codebook, review and refine the themes, and export coded results back into the formats your team and clients need.
The platform combines the speed of AI with human-quality coding, giving researchers more control, transparency, and consistency than generic text analytics tools.
Market research agencies use Blix to reduce manual coding time, handle large volumes of open-ended responses, improve turnaround times, and deliver better insights to clients.
Instead of spending hours reading and categorizing verbatims manually, teams can quickly identify key themes, quantify response patterns, and understand what customers, consumers, or employees are really saying.
Blix supports multilingual open-end coding, brand awareness coding, customer feedback analysis, and survey text analysis across a wide range of research projects. It is especially useful for agencies managing recurring trackers, high-volume surveys, multi-market studies, and projects where speed, accuracy, and consistency are critical.
