Create, edit and translate layouts with AI
Describe the email you want and let AI build the layout, change an existing one, or translate it. You use your own account with Anthropic (Claude), OpenAI, Google Gemini or OpenRouter, so there are no AI credits to buy in the app and you pay your provider directly.
Connect a provider
- Create an API key with the provider you prefer: How to get an Anthropic (Claude) API key, How to get an OpenAI API key, How to get a Google Gemini API key or How to get an OpenRouter API key.
- In the app, open Developer and the Connections tab.
- Paste the key into that provider's card and save. The key is checked with the provider first.
- Pick the Default model. You can connect several providers and choose one each time you generate.
The key is encrypted and only used when you generate, edit or translate a layout. It is never shown again and never returned by the app's API.
Create a layout
With a provider connected, Create Email Layout opens a Create a layout with AI window. Choose the editor (visual builder or rich text / HTML), describe the email, for example an order confirmation with a thank-you heading, the order items and a button to track the order, and click Generate. The draft fills the page; review it and Save.
Edit a layout
The layout editor shows an Edit with AI bar. Describe a change, for example add a line items table or make the tone friendlier. The whole layout is updated in the editor; nothing is saved until you click Save, and Discard brings back what you had.
Translate
In Languages, choose Translate with AI when adding a language. See Send emails in your customer's language.
Choosing a model and cost
The model list comes from your provider account, so new models appear without an app update. Each model with a known price shows an estimated cost per generation (a full layout), billed to your provider account, not your plan. Larger models write better designs and take longer.
| Provider | Good defaults | Models and prices |
|---|---|---|
| Anthropic (Claude) | Claude Sonnet 5 (about $0.06 per layout), Claude Opus 5 for complex designs | Models, pricing |
| OpenAI | GPT-5.6 Terra (about $0.07), GPT-5.6 Luna for low cost | Models, pricing |
| Google Gemini | Gemini 3.8 Flash (about $0.02), Gemini 2.5 Pro | Models, pricing |
| OpenRouter | Any listed model; one key for many companies | Models and prices |
OpenRouter is the easiest way to try models from several companies with one key and one balance. If a model is not in the list, choose Other model id on the Developer page.
Models and prices change over time; the provider's pages are the reference.
Good to know
- Generated layouts are checked like any layout: Liquid must be valid and only your own uploaded files can be used. The AI never picks images from your media library; add those yourself.
- Larger models take longer; a full layout can take a minute or two.
- A bad or expired key shows the provider's error when you generate.
- Prefer to work from your own assistant? Connect it over MCP and ask it to build layouts: see Connect an AI assistant (MCP).
