Google releases Deep Review to check long technical documents, two free a week

Google Research has publicly released Deep Review, an agentic AI system that checks long technical documents for logical consistency, verifies mathematical statements, grounds facts and compares the work with existing literature. It grew out of the Paper Assistant Tool, which gave opt-in, pre-submission feedback on more than 16,000 manuscripts at STOC 2026, ICML 2026, NeurIPS 2026 and ICLR 2027, and Google says it now covers documents in fields such as law and finance. Every user gets two free reviews a week, and heavier users can connect a Gemini API key for higher limits and API access. It accepts PDFs and plain text for now. Google says uploaded documents are never used to train its models and are stored for one year only so they can be shown in the Deep Review interface. Sorted take: a cheap second reader for long reports, contracts or papers, but treat its findings as prompts to check, not a sign-off.
