Step 3 Difficulty discovering interest-based local social groups

Problem

After retirement, social connections for people in their 50s-60s shrink rapidly, increasing depression and isolation. To find local groups with shared interests (hiking, board games, book clubs, community gardening, etc.), they must separately search community center bulletin boards, Naver Cafes (Korean online forums), and KakaoTalk open chats. Joining Platforms designed for people in their 20s-30s (like Somoim or Munto) feels uncomfortable due to the generational gap, and there is no centralized source for groups specifically for those 50 and older.

Solution

Users select their neighborhood (district-level) and interests, and the system aggregates local social group information for ages 50+ in one place. It crawls and integrates data from community center lifelong learning programs, Naver Cafes, KakaoTalk open chats, and library reading groups, then structures and compares age range, activity frequency, and membership fee information. A feature to create new groups is also provided.
