Frequently Asked Questions

What is the best AI for analyzing documents?

Claude Pro leads for long-document analysis — its 200,000-token context window handles 150,000-word documents in a single session with zero fabricated citations in Bottley's 50-document benchmark. Gemini Advanced wins for Google Drive document analysis. Docugami wins specifically for contract extraction at scale.

Can AI analyze legal documents?

Yes, with important caveats. Claude, GPT-4o, and Gemini Advanced all achieve 85%+ accuracy on clause identification and definition extraction from standard commercial contracts. However, AI tools miss jurisdiction-specific nuances and should not replace legal review — they accelerate it. Average time savings: 2.3 hours per contract on initial review.

What is the best free AI document analyzer?

Claude's free tier handles documents up to 30,000 tokens (approximately 22,000 words) with strong extraction accuracy. For PDFs specifically, Smallpdf's AI features offer free document Q&A on documents up to 14MB. ChatGPT's free tier allows file uploads with document analysis via GPT-4o mini.
