Frequently Asked Questions

Is Claude AI safe for confidential documents?

Claude AI sends your data to Anthropic's servers for processing. While Anthropic has strong safety practices and won't use your data for training (with Claude Pro), your confidential documents still leave your control. For attorney-client privileged information, HIPAA data, or trade secrets, local processing with Vult is safer.

How does Anthropic handle my Claude conversations?

Anthropic retains Claude conversations for 30 days by default for safety monitoring. Your inputs may be reviewed by Anthropic staff for safety purposes. With Claude for Business, you get additional controls, but data still travels to Anthropic's cloud infrastructure.

Is Vult as capable as Claude 3.5 Sonnet?

Claude 3.5 Sonnet is one of the most capable AI models available. Vult uses leading open-source models like Llama 3 and Mistral which are highly capable for document analysis and business tasks, though Claude may have an edge in some complex reasoning tasks. The key tradeoff is privacy: Vult keeps your data local.

Can I use Claude for GDPR-protected data?

Using Claude with GDPR-protected personal data requires careful compliance consideration. While Anthropic offers data processing agreements, your data still transfers to their servers. Vult avoids this entirely by processing everything locally.

What about Claude Enterprise?

Claude Enterprise offers enhanced privacy controls and SOC 2 Type II compliance. However, your data still leaves your organization and is processed on Anthropic's infrastructure. For maximum data control, Vult's local processing remains the more secure option.
