Aozora Research is a research browser designed for deep web searching, product research, company research, and price comparison.

Aozora Research helps you keep them organized by research theme. You can save web pages, manage product and price notes, store company notes, use tabs, open private tabs, search within a page, open pages in Google Translate, save favorite sites, and search across your saved information. It is useful for repeated research tasks such as finding parts, comparing products, checking prices, collecting seller information, researching repairs, and saving useful web pages for later. Main features: - Research themes - Free Research mode for quick searches - Save web pages - Tab browsing with up to 5 tabs - Page thumbnails in the tab list - Private tabs - Find in Page - Open in Google Translate - Favorite Sites - Product and price notes - Company notes - Browsing history management - Global search across saved information - Share current pages - PRO unlock to remove the free theme limit Aozora Research is made for people who want to search, save, compare, and review information without losing what they found.
