Our go-to for anything sensitive

Diana K.·Head of Product·E-commerce Platform

We use Claude for everything that involves customer data or proprietary information. The privacy-first approach means our legal team actually approved it. Only wish the free tier were more generous.

Use case: Customer analytics, product development

Pros

  • +Privacy-first design
  • +Excellent reasoning
  • +Good enterprise controls

Cons

  • -Free tier is limited
  • -API costs add up quickly

Best privacy posture of any AI provider

Mike R.·CISO·Financial Services Firm

After evaluating every major LLM provider, Claude won on security. No training on data by default, zero-retention API, HIPAA BAA available, and the safety approach gives our compliance team confidence. The 1M context window is a game-changer for document analysis.

Use case: Document review, compliance analysis

Pros

  • +No training on user data
  • +HIPAA BAA available
  • +Excellent long-context performance
  • +Strong safety approach

Cons

  • -Smaller ecosystem than OpenAI
  • -Context window can be expensive at scale
