Google Research launched Deep Review publicly. It evolved from the Paper Assistant Tool used in 16,000+ academic submissions. The tool now reviews technical documents beyond papers, including legal and financial files. It uses a four-stage agentic pipeline for deep verification. Users get two free reviews per week. Higher limits require a Gemini API key. Documents are never used for model training. Deep Review also integrates with Antigravity via a new pattern. Multi-file support is coming soon.
