Google launches Deep Review, an AI tool for verifying technical documents

Key points

• Deep Review is now publicly available worldwide, expanding beyond academic papers to Google Docs and presentations.
• Every user gets two free document reviews per day; high-volume users can connect a Gemini API key for more.
• Initially supports PDFs and plain text; multi-file inputs are described as coming soon.
• Uploaded documents are not used to train Google models and are stored for one year for display in the Deep Review UI.

Why it matters for marketers: Content teams can run pre-publication checks on claims, consistency and data tables, and integrate verification into drafting workflows via API.
