Show HN: Hika – A AI search engine that explores knowledge from multiple angles (opens in new tab)

I built Hika during GAP years, focusing on a different approach to AI search. Key features:

* Paragraph segmentation for deep dives into specific topics * Visual knowledge graphs for concept exploration * Interactive follow-up questions * Professional knowledge source integration * Free to use

We've been operating for several months with positive user feedback. Built with friends over the past year, focusing on thoughtful exploration rather than just quick answers.
