We have added new AI functionality that makes expense automation faster and smarter than ever. These new changes include LLMs for:

- **High-risk expense flagging:** Brex AI will flag “vodka” even when “alcohol” isn’t on the receipt.
- **AI-powered commenting**: Brex’s AI assistant will start a conversation with you to explain why an expense is out of policy.
- **Smart filtering on search: **Ask Brex AI for _“marketing expenses > $200 without receipts last month”_ and instantly get a list of filtered expenses.
