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, 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 that specific design 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.

​

The Emails Section

Open Emails in the sidebar. A toggle at the top switches between two tabs: Emails (one-off sends) and Automations (triggered flows).

​

The Emails Canvas

When you create an email, it appears on the Emails canvas. The canvas is your working surface for one-off emails. From here you can:

• See several designs side by side: when one prompt produces multiple emails, they appear next to each other on the same row
• Click into any email to edit it
• Resize, clone, or delete any email from the toolbar
• Switch between versions: every edit creates a new version, and the version dropdown lets you preview earlier ones
• Import designs from Figma, HTML, or images

Canvas view vs list view. Toggle between two views from the top of the Emails tab:

• Canvas view. Best for creating and editing. The default working surface.
• List view. Best for scanning a large library. Shows every email in a compact table.

​

The Automations List and Flow Editor

Switching to the Automations tab opens a list view, every automation with its status and trigger. Click an automation in the list to open it on its own flow canvas. Each automation has a dedicated canvas, so the flow you’re editing is always exactly the one you selected. The flow editor shows the trigger, Send Email nodes, Wait nodes, Filter nodes, and Split nodes. Click the trigger node to edit or change what starts the flow: an integration event, a custom HTTP trigger, or a manual audience you run on demand. You can still use chat to make changes; the artifact you’re editing is a flow instead of a single email. For everything about building automations, see Automations.

​

Import Tools

Already have email designs? Bring them into Brew from the Import tools on the right side of the canvas: You can also forward emails to hello@email.brew.new. Forwarded emails land in Templates → Forwarded and can be remixed into your brand.

​

Navigation Shortcuts

Global search. Press Cmd+K (or Ctrl+K) to search navigation, emails, contacts, settings, and integrations from anywhere in the product. 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

By default, Brew uses Claude Sonnet for the orchestrator and Claude Haiku for fast email generation. Change models any time from Settings → AI:

• Anthropic (Claude Sonnet, Claude Haiku)
• OpenAI (GPT-4.1 Mini, GPT-5 Nano)
• Google (Gemini 3.1 Pro, Gemini 3 Flash)

You can also enable reasoning effort (low / medium / high) for slower but more thoughtful generations on Anthropic models.
