⚖️ Privilege protection important note

Brainiall provides technical safeguards consistent with attorney-client privilege preservation: Zero Data Retention mode (Business plan), no model training on customer data, EU data residency, encrypted at rest + in transit, DPA + AVV available.

Important: Each jurisdiction has different privilege rules. Consult your bar association before sending privileged communication to any AI service. We recommend ZDR mode + DPA + internal AI policy for law firm deployments.

# Read 200-page contract (fits in 1M context)
contract_text = open("acquisition_agreement.pdf.txt").read()

# Single query gets full analysis
response = client.chat.completions.create(
    model="claude-opus-4-7",  # 1M context, best reasoning
    messages=[
