What Is HiDocument?
Quick Answer: HiDocument is an AI-powered document intelligence platform that gives anyone — not just enterprise law firms — access to 10 types of professional document analysis. Upload a PDF, Word doc, or image and Claude AI returns a summary, risk flags, PII compliance score, document chat, timeline, and more in under 30 seconds.
Our Mission
Document intelligence should not be a luxury reserved for Fortune 500 legal departments. Independent attorneys, small law firms, compliance officers at growing startups, contract managers at agencies, and freelancers all read dozens of documents a week — often without the tooling that big-firm associates take for granted.
HiDocument exists to close that gap. We use Anthropic's Claude AI — one of the most capable language models in the world — to deliver the same depth of analysis a senior associate would produce in two hours, but in under 30 seconds and at a price anyone can afford.
How does HiDocument work?
- Upload any PDF, Word doc, plain text file, or image (we OCR images automatically).
- Claude AI analyzes the document and generates 10 types of insights in parallel.
- Explore the results across tabs: summary, risk flags, PII scan, timeline, document chat, and more.
Why Claude AI?
We chose Claude (specifically the claude-sonnet-4 model) because it is one of the best models in the world at long-form reasoning, structured output, and following nuanced instructions. Document analysis demands all three. Claude reads your contract end-to-end, identifies one-sided indemnification clauses, spots auto-renewal traps, and answers your questions with verbatim source quotes — not hallucinations.
