About "見える化エンジン"
What is Mieruka Engine
Mieruka Engine is a platform from Plus Alpha Consulting Co., Ltd. (listed on the Tokyo Stock Exchange Prime Market) for analyzing and visualizing the Voice of the Customer (VOC). It ingests text data scattered across inquiries, surveys, social media, call-center audio and more, analyzes it with text mining and generative AI, and "visualizes" it into a form usable for marketing and product development. It has held the No.1 domestic share of the text-mining tool SaaS market for 14 consecutive years, with over 1,900 companies deploying it.
The core is text mining, and generative AI complements and automates that analysis. Recently it has added generative-AI features such as "AI-managed analysis reports" and "AI Interview," and officially positions itself as a "generative-AI-equipped Voice-of-the-Customer platform" (as of August 2026).
Visualize scattered "customer voices"
Customer voices are scattered across inquiries, surveys, social media and call centers, making them hard to use as-is. Mieruka Engine takes in this text data and visualizes what is being said and what emotions are moving. On top of 40+ analysis functions, generative AI automates summarizing key points and producing reports, so even non-analysts can gain insight.

Track record
14 straight years, domestic share
Plus Alpha Consulting
In Fuji Chimera Research Institute's study (Software Business New Market 2025 edition), it has held the No.1 domestic share of the text-mining tool SaaS market for 14 consecutive years.

How Mieruka Engine differs from other VOC/analytics tools
Mieruka Engine stands out for specializing in text mining and combining 40+ analyses with generative-AI automation in one tool. Its breadth differs from spreadsheet tallying or single-purpose analysis tools.
| Aspect | Mieruka Engine | Spreadsheet tallying | Single-purpose tools |
|---|---|---|---|
| Analysis | Dependency/sentiment/network + generative AI | Manual tallying | Only specific analyses |
| Voice types | Inquiries, surveys, social, audio | Scattered by file | Limited |
| Strength | No.1 share, auto reports | Simplicity | Purpose-specific |
Around customer touchpoints, Neurons (predicting reactions to ad creative), Intercom Fin AI (inquiry handling) and Helpfeel (resolving via search) are adjacent comparisons/complements. For companies that want to analyze scattered customer voices and act on them, Mieruka Engine is a standard choice.
To consider it alongside the self-service and conversation-handling types that sit upstream of analysis, see Customer Support AI Tools Compared: 8 Products.
