Kagi could differentiate itself as a news aggregator by leveraging its' search engine capabilities to find relevant primary sources. E.g. the actual filed complaint from courtlistener relevant to the story below.
This would be shown similarly to relevant news publication sources, but in its' own section, as well as being used as a source for LLM generated summaries.

This would create 2 seperate "sources" article sections for primary and secondary sources.
Google news occasionally aggregates major government announcements, but they are not differentiated as a primary source, which makes it less clear that primary sources suffer from the bias of being directly involved with the article subject. E.g. the civil complaint referenced above is written by one party in an adversarial legal system, basing it in favor of the complainant.
