Microsoft has announced the removal of the Deep Research feature from Copilot, effective August 18, 2026. Previously available at no extra cost, this capability for generating in-depth reports and analyses will be replaced by the new Researcher tool, which requires a Microsoft 365 Premium subscription. Existing content will remain accessible, but interaction will require payment. A decision that has disappointed many users, yet several free alternatives exist.
Perplexity: real-time research with verified sources
Perplexity stands out for providing answers backed by citations and verifiable claims. Its real-time web search makes it ideal for news, products, and academic studies. The free tier is fully functional and represents a worthy replacement for everyday analysis.
Claude: deep analysis with specialized connectors
Claude from Anthropic can generate long-form explanations with legitimate citations. It offers connectors such as PubMed, bioRxiv, and Consensus, which serve as research databases. A strong choice for those needing structured reports and academic sources.
