Research agents break a question into steps, gather information from multiple sources, and produce a synthesis. This collection focuses on sustained research workflows. Academic search engines and fast answer tools can supply useful evidence, but are separate workflows. The existing product profiles include their research features, so a feature such as Gemini Deep Research or You.com's ARI does not need a second listing. Compare source access, report structure, citations, and the ability to review or steer the research before treating the result as a decision aid.
