Quest Research is a Japan-based AI × market research service provider. Built around its in-house “コルク” product series, it offers AI interviews, quantitative surveys, and research consulting. It is positioned not simply as a survey tool, but as a combination of generative AI products and delivery by researchers/consultants, helping companies collect and analyze consumer feedback faster and turn it into “Next Action.” According to its website, customers include large operating companies, consulting firms, and startups.
Its product lineup includes “コルクインタビュー” (formerly qork) and “コルクサーベイ” (formerly コエミル). The former is used for AI interviews and qualitative research; company news mentions thousands of AI interviews conducted in total, with interviews of around 100 people completed in as little as one day. The latter is for quantitative surveys, with copy claiming completion in as little as two days and support from survey design through distribution. Its AI capabilities also include automatic survey screen generation, test automation, and generative AI-assisted analysis. However, the website does not disclose details about the specific models used, algorithm evaluations, sample control mechanisms, or API capabilities.
The website does not publish plans or pricing. Lead generation is mainly handled through document downloads, free consultations, and inquiry forms. Company news mentions limited-time trials, but does not specify quota, duration, or eligibility. Before purchasing, buyers should directly confirm SaaS fees, project-based pricing, sample costs, and the scope of deliverables.
Its strengths are that it covers both qualitative and quantitative research, and can provide one-stop delivery from research design, execution, and analysis to reporting. The team’s background includes strategy consulting, research, and data analysis, making it better suited to customers seeking business insights rather than just data tables. The downsides are that publicly available information is relatively marketing-oriented, with limited transparency around model details, data privacy, integrations, Chinese-language support, and pricing. Enterprise compliance and cross-border usage require additional due diligence.
It is suitable for Japan market research, new business validation, brand awareness studies, concept testing, customer satisfaction, and consumer insight projects—especially for companies that lack an internal research team but need speed. Access from mainland China is unclear. The site is in Japanese, and there is no visible Chinese-language customer support or information about RMB / domestic Chinese payment options. For China-focused samples or Chinese-language research, alternatives to compare include 问卷星, 腾讯问卷, local research firms, or international solutions such as Qualtrics, SurveyMonkey, and Dovetail.
