Quest Research Integrates AI Research Product Group into "Cork" Series. Transitions to New System for Seamless Qualitative and Quantitative Research Provision.

Quest Research Inc. (Headquarters: Minato-ku, Tokyo; Representative Director: Kenta Minami), which provides AI research solutions, announced on April 14, 2026 (Tuesday) that it has rebranded its AI product group, which covers both qualitative and quantitative research, as the new "Cork" series.

The AI qualitative research product "qork" has been renewed as "Cork Interview," and the AI survey analysis tool "Koemiru" has been renewed as "Cork Survey," integrating the two products into the same series. Moving forward, these two products will be more closely integrated, establishing a system that can seamlessly operate qualitative and quantitative research on a single platform.

First Pillar: "Cork Interview" Evolved with Over 8,000 AI Interview Achievements

"Cork Interview" has been continuously and rapidly updated based on customer site needs. Over the past six months, the AI interview function has been strengthened to be even easier to use for both researchers and respondents.

【Main Updates】 Large-scale parallel support: Enables simultaneous AI interviews with over 100 people. Also supports large-scale VoC collection. Dictionary function: Automatically prevents variations in notation by pre-registering industry terms and proper nouns, reducing analysis man-hours. Refreshed LLM model and enhanced voice function: Updates to the latest model and improved voice reading realize a more natural conversational experience and highly accurate automatic transcription.

【Case Study: Social Research Service Inc. (SSRI)】 Social Research Service Inc. (SSRI), a major player in the medical research industry, has adopted the evolved Cork Interview.

Second Pillar: From Quantitative Survey Respondents Directly to Interviews. "Cork Survey"

Guiding respondents who participated in a Cork Survey directly to a Cork Interview via API to delve into the "why" behind quantitative trends – this is the new collaborative experience between quantitative and qualitative research that the "Cork" series realizes.

Intuitive design and AI automatic check: While creating surveys with an intuitive operation screen, AI detects question bias and logic flaws before distribution. Immediate aggregation and delivery after completion of actual survey: Distribution, collection, and cross-tabulation are completed in one stop. Decision-making speed is not slowed down by overwhelmingly fast delivery within a minimum of 2 business days. MCP integration to utilize organizational knowledge: Seamlessly connects with external AI tools to automate and streamline analysis. AI refers to accumulated survey data, improving design and analysis accuracy with each survey.

By combining this product, which has over 1,200 achievements, with Cork Interview, end-to-end research – "grasping trends quantitatively and delving into causes qualitatively" – can be completed with "Cork" alone.
