Free Web Search Ultimate

Free Web Search Ultimate (canonical repo: cross-validated-search) is a tool for evidence-aware web search, browsing, and automated claim verification designed for AI agents. It combines live search, page reading, and structured evidence analysis to produce citation-ready, source-backed results with confidence signals. It supports common agent workflows (CLI, MCP, skill surfaces for Gemini, Claude Code, Manus, and more) and works with both free and self-hosted search providers. The tool is ideal for developers, researchers, and ecosystem integrators seeking more robust, transparent, and reasoned web search workflows for AI-powered systems.
