"Let's Ask AI About Subsidies" -- "Hojokin Sagasu AI" Launched, Finding Optimal Subsidies with jGrants Official Data x AI Search

jGrants API integration automatically updates subsidy information daily. "Hojokin Sagasu" is completely free and requires no registration.

X-HACK Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo; Representative Director: Shinsuke Matsuda) launched "Hojokin Sagasu AI" ( https://hojokin-hub.ai ), a free web service that allows users to search for subsidies and grants using AI, on March 24, 2026. By combining a natural language AI search with the official database linked to the jGrants API operated by the Digital Agency, the service proposes optimal subsidies in response to queries such as "What subsidies can be used for IT introduction?" or "Tell me about equipment investment subsidies for manufacturing industries."

Development Background

For small and medium-sized enterprises (SMEs) and sole proprietors, subsidies and grants are crucial funding sources for business growth. However, information is dispersed across ministries and local governments, leading to many voices saying, "I don't know which subsidies I can use" or "I don't have time to search."

Many existing subsidy search services are keyword-centric, assuming users know the appropriate search terms. However, for businesses unfamiliar with subsidies, the biggest hurdle was often not knowing what to search for in the first place.

"Hojokin Sagasu AI" offers a new search experience where AI finds the optimal subsidy simply by describing your business in your own words.

Service Features

【1. AI Search ── Proposes optimal subsidies by simply describing your business】 Based on the concept of "Let's ask AI about subsidies," it is equipped with natural language AI search. By simply asking in your own words, such as "Subsidies available for IT introduction" or "Startup funds for restaurants," the AI proposes the optimal scheme from the nationwide subsidy database. You can find the right subsidy for you even without specialized knowledge of subsidies.

【2. jGrants API Integration ── Official data automatically updated daily】

Linked with the jGrants API, the electronic application system for subsidies operated by the Digital Agency. It automatically acquires and updates national and local government subsidy information daily, always reflecting the latest application status. Subsidies whose application periods have ended are automatically updated, so there's no need to worry about outdated information.

【3. Completely Free, No Registration, No Ads】

All functions are provided free of charge. You can search for and view details of subsidies without creating an account. There are also no advertisements.

【4. Comprehensive Refined Search】

In addition to AI search, traditional search functions are also enhanced. - Full-text keyword search (cross-searches subsidy names, descriptions, eligible applicants, and implementing organizations)- Regional filter for 47 prefectures + nationwide- Filter by application status (open for application, scheduled for application, closed)- Filter by industry category- Highlight display for subsidies with approaching deadlines

In the future, new AI-powered features will be added sequentially, such as an AI business plan verification function and AI support functions to improve adoption rates.
