Loose Days Inc. Launches “mipy,” an AI Item Search for Natural Language Queries
TOKYO, Japan – September 15, 2026 – Loose Days Inc., headquartered in Shinjuku-ku, Tokyo, and led by Representative Director Seiji Nakaya, today announced the official launch of “mipy” (https://mipy.jp), an AI-powered item search service. mipy allows users to find products by simply describing what they are looking for in natural language, such as “a mobile battery I can bring on a plane” or “a JIS layout mobile keyboard I can carry around daily,” eliminating the need for specialized product knowledge. The AI interprets these natural language queries into specific product specifications and presents comparable items from approximately 1,500 products, including no-brand items, across multiple shops. The service is free and requires no registration.
Background: The Challenge of Spec-Based Searching Without Expert Knowledge
Traditional search and comparison sites often require users to understand technical specifications like “Wh” or “DisplayPort Alt Mode” and their typical values. This presented a significant barrier for users without specialized knowledge who wanted to find specific items, such as a “mobile battery that can be carried on an airplane” or a “PC that can connect to a conference room monitor.”
Furthermore, comparing no-brand products is particularly challenging. Their product names and spec notations can vary widely across different shops (e.g., “100Wh” versus “27,000mAh/3.7V” for the same specification), making them difficult to compare using conventional model number-based comparison systems.
What mipy Offers
-
Search with Natural Language Descriptions
Users can input their desired item using everyday language. The AI translates these phrases into specific conditions, such as interpreting “can be carried on a plane” as “under 100Wh” or “portable” as “lightest first,” and displays products that meet these specifications. The AI’s interpretation is shown on screen, allowing users to rephrase their query if the results are not as intended.Examples of searches:
-
“A JIS layout mobile keyboard I can carry around daily”
-
“A USB-C hub that can output 4K 60Hz”
-
“A mobile battery I can bring on a plane”
-
-
Compare No-Brand Items by Specifications
mipy reads specifications from product pages, images, and manufacturer-published information, standardizes units, and compiles them into a comparison table. If the same product is sold by multiple shops, mipy consolidates them, displaying the lowest price and price trends.
-
Pre-defined Comparison Pages for Common Conditions
mipy provides comparison pages for frequently searched conditions, such as “USB-C hubs that output 4K 60Hz video” or “inkless mobile printers.” Products for which condition values cannot be verified are excluded, and key metrics like the number of applicable items, lightest weight, and median values are displayed.
Note: The search results in the images were from the development stage. Prices and other details may have changed.
-
Automated Daily and Weekly Updates
Prices and stock are updated daily, while specification readings and classifications are updated weekly. When numerical values have a source, it is listed alongside the data.
