The Interface

Brew is built around one idea: you describe what you want, Brew builds it. Everything starts in chat. This page explains where things live and how to move around.

​

The Chat

Every interaction starts in chat. Open it from Home, or use the chat panel on the left side of the canvas. Type what you want and submit. You can ask for one email, several at once, a full automation flow, or edits to something you’ve already made:

• “Create a Black Friday email with a product grid and a 24-hour countdown.”
• “Generate three subject-line variations for this announcement.”
• “Build a 4-step welcome flow for new SaaS trial users.”
• “Preview this across real inboxes.”
• “Make this more direct and cut it by half.”

Brew picks the right tool based on what you ask. That could mean generating an email, editing one, building variants, running an inbox preview, or assembling an automation flow. You don’t select a mode. Add to chat. Select any email on the canvas and click Add to chat in the toolbar to bring it into the conversation. Edits and previews you ask for then run against it, without touching anything else on the canvas. Chat tabs. Open a new chat, switch between active chats, or reopen an older conversation using the tabs across the top of the canvas. From an agent, list_chats over MCP (GET /v1/chats) lists the brand’s chats, most recently active first, and get_chat_context picks one up where it left off.

​

Canvases

A canvas is a working surface scoped to one container. You never see everything at once. You open a container, and the canvas shows what lives inside it. Both Emails and Automations open the same way: a list of containers, one card or row each, and a click to enter. What the container is depends on the feature.

​

Emails

Open Emails in the sidebar. The container is a group, and each group has its own canvas holding that group’s designs side by side. Ungrouped is the default, and New canvas creates a named group. For how groups work, what you can do on a group’s canvas, and the Groups and List views, see Groups and Canvases.

​

Automations

Open Automations in the sidebar. The container is the automation itself, and its canvas is the flow editor: the trigger, then the sequence of Send Email, Wait, Filter, and Split nodes. For the list and the node reference, see Automations. For the build, test, and publish workflow, see Build an Automation.

​

Import Tools

The Import tools sit on the right side of the canvas. They bring existing HTML, a Figma frame, or a screenshot in as an editable email. See Importing existing designs for what each one does.

​

Navigation Shortcuts

Global search. Press Cmd+K (or Ctrl+K) to search navigation, emails, contacts, settings, and integrations from anywhere in the product. Notifications. The bell at the top right lists what finished or failed (generations, sends, imports, domain checks), plus comment mentions and replies addressed to you. Mark all read clears the dot in this browser. From an agent, list_notifications (GET /v1/notifications) reads the same list without marking anything read. An API key sees only the rows its scopes cover and never a comment mention or reply, which reach only the person they’re addressed to. Send-limit alerts reach organization admins only. Brand switcher. The active brand is shown at the top of the sidebar. Switching brands updates the canvas, audience, automations, analytics, domains, and integrations, everything scopes to whichever brand is active.

​

AI Model Picker

Brew defaults to Claude Opus 4.8 for the orchestrator and email agents. Change the model or the reasoning effort from Settings → AI; Settings lists the options.
