Brex
Six ways to run it from a message.
Drive it by message when you need it, or put it on autopilot.
Create from voice
Record expenses, set up new cards, or create departments by voice message from WhatsApp, Telegram, or Slack.
Set up budgets and cards
Message 'Create a $100k marketing budget' or 'Add a card for sales' to configure Brex without navigating the web app.
Ask about your spend
Question: 'Show me all transactions over $500' or 'What are my active budgets?' and Notis delivers instant answers from your Brex account.
Weekly spend summaries
Receive daily or weekly digests of your top transactions, budget usage, card activity, and department spend delivered to your messaging inbox.
Scheduled Brex actions
Set Notis to run recurring tasks like 'pull all expenses from last month' or 'list this week's transactions' on your schedule.
Link to your workflow
Connect Brex with Slack, Google Sheets, or accounting tools to sync expenses, automate reconciliation, and unify your financial workflows.
