Arlong

Arlong is a search engine built for both human readers and AI systems. It provides web search results enriched with link evaluations, source context, and threat analysis, allowing users to inspect the underlying evidence. For AI agents, Arlong outputs predictable, structured data records containing relevance, reputation, and threat metadata. The platform also screens for indirect prompt-injection attempts and isolates flagged content from the downstream context. The platform operates on a subscription membership model, offering API and Model Context Protocol (MCP) access with selectable research depths ranging from quick routing to deep parallel extraction.
