Google's free Deep Review checks long documents for gaps and inconsistencies
Deep Review is a Google Research tool that reads a long document and reports where it contradicts itself or makes unsupported claims. Google says it can check internal consistency across clauses and data tables in legal and financial documents, flag ambiguous terms, and test whether presentation takeaways match their charts. It began as a reviewer for academic papers and was piloted on more than 16,000 conference submissions. For a small business owner, it offers a second read on a contract or proposal before sending it. Its findings are a starting point for review, not a guarantee of accuracy.
- For
- Creatives and small business owners who write or receive long documents such as proposals, contracts, pitch decks, or financial summaries and want an extra check before relying on them.
- Cost
- Free for two document reviews per week, per Google. Users who need more can connect their own Gemini API key for higher usage limits and access to the Deep Review API. Google does not state the API pricing in this announcement.
- Access
- Google says Deep Review is available worldwide through the Google Research portal. Input is initially limited to PDFs and plain text, with multi-file uploads described as coming soon. Google says uploaded documents are never used to train or improve its models and are stored for one year so they can be displayed in the Deep Review interface.
Your moveOpen Deep Review on the Google Research portal and test it with a non-sensitive PDF, such as an old proposal. Read the data policy before uploading anything confidential, because Google keeps uploaded files for one year.
