Is a design API the same as an image generation API?

No. An image generation API produces a flat raster image where text is pixels and nothing is editable. A design API produces a structured, multi-layered design where text is real text, every element is on its own layer, and the entire output is editable.

Can a design API replace a graphic designer?

For high-volume work like bulk product banners, social post variations, and ad creatives in multiple sizes and languages, yes. For strategic brand work and custom creative direction, you still need a designer.

Do I need templates to use a design API?

No. A generative design API like Sivi creates original layouts from scratch. You send a prompt or structured content, and the model composes a new layout every time. No templates to build or maintain.

How does a design API handle brand consistency?

Through a brand kit. You upload your brand's colors, fonts, logos, and style rules once. The API enforces them on every design generated under that brand kit. No manual review needed.

Can a design API generate designs in multiple languages?

Sivi supports 72+ languages including RTL scripts (Arabic, Hebrew, Urdu). The model generates designs directly in the requested language, re-composing the entire layout so typography, reading direction, and spacing work correctly.

How do AI agents use a design API?

Through the Model Context Protocol (MCP). The AI agent treats the design API as a callable tool — it sends a design brief, receives a layered design back, and presents it to the user. Any MCP-compatible assistant can generate marketing designs as part of a conversation.

What's the cost of using a design API?

Sivi's design API starts with a free sandbox (10 designs/day). Paid plans start at $96/month for 800 designs. At scale, that's roughly $0.11 per design — compared to $15+ per banner with manual design at $60/hour.

Do I need to know how to code to use the design agent skill?

No. The skill runs inside your AI coding assistant. You type a natural language prompt describing the design you want. The skill handles the API call, polling, and result display automatically.

Can I use my brand colors, fonts, and logos with the design agent skill?

Yes. Pass colors as hex codes and logos as URLs directly in your prompt. For full brand kit management including fonts, brand components, and style rules, set up a brand kit in the Sivi dashboard and use it via the API.

How is the design agent skill different from using the Sivi API directly?

It uses the same API. The skill is a convenience layer that handles prompt parsing, payload construction, polling, and result display. If you are building an integration, use the API directly. If you want to generate designs from your IDE, use the skill.

Design agent skill

Turn your AI coding assistant into a design agent. Type a prompt, get back layered, editable, on-brand designs. No browser, no design tool, no context switching. This is an open-source agent skill that wraps the Sivi design API. It works with Claude Code, Cursor, GitHub Copilot, Windsurf, Cline, and 17+ AI agents. You bring your API key. The agent skill handles the rest: parsing your brief, calling the API, polling for results, and displaying the output inline.

How the design agent works

Step 1

Describe your design

Type a natural language prompt in your AI coding assistant. A simple prompt such as "Instagram post for a summer sale on outdoor furniture" or a detailed one like this: "Create four different Facebook ads. Headline: Refined Sanctuary, Description: Transform your home with KraftHaus Living., Button: Explore Now. Brand Colors: #CAAB75, #F8F8F8, #000000". Use logo from https://media.hellosivi.com/logos/s6FVztpTVjO.svg.

Step 2

The design agent calls the Sivi API

The agent skill parses your prompt, selects the right design type and size, and sends the request to the Sivi design API with your API key. You can also specify text message, colors, themes, logos, images, language, and dimensions. The Sivi API uses the Large Design Model and composes the design.

Step 3

Get designs inline

The design agent polls for results and displays the generated design variants directly in your IDE. Each variant includes a preview image and an edit link to the Sivi design studio where you can fine-tune and export. Note that Claude code does not display the image inline.

The designs are also downloaded to your local folder.

One prompt. Multiple design variants. Layered, editable output. A design agent that works where you code.

How to install the design agent skill

One command via skills.sh

Install the sivi/skills design agent with a single command. Works with Claude Code, Cursor, GitHub Copilot, Windsurf, Cline, and 17+ AI agents.

That's it. Your AI coding assistant is now a design agent.

Clone from GitHub

Alternatively, clone the repo and set up manually.

git clone https://github.com/sivi/skills.git

# Add your Sivi API key
echo "SIVI_API_KEY=your_api_key_here"

That's it. Your AI coding assistant is now a design agent.

MCP (Model Context Protocol)

The skill can be packaged as an MCP server for use with any MCP-compatible client - Claude Desktop, Cursor, Windsurf, and others. See the GitHub repo for MCP setup instructions.

Get your API key

You need a Sivi API key to use this skill. Sign up at the Sivi web app and get sandbox access.

All parameters except the prompt are optional. The design agent uses sensible defaults.

Skip the browser. Skip the design tool. Generate production-ready marketing designs from the same terminal where you write code.

Sivi's design API gives you three integration paths: REST API for backend automation, SDK for embedding a design studio in your frontend, and MCP server for AI agent workflows. All three enforce your brand kit automatically.

Skip the browser. Skip the design tool. Generate production-ready marketing designs from the same terminal where you write code.

Why a design agent inside your IDE

Developers, marketers, and founders who work in the terminal or IDE shouldn't have to open a browser, log into a design tool, and context-switch to create a quick banner or social post.

This agent skill puts a design agent where you already work. It's the same Sivi API that powers production design pipelines for ecommerce platforms and agencies - just accessed through a conversational interface instead of code.

What business owners, marketers, AI enthusiasts, and designers say about Sivi

I like how the prompt wizard is created. Generate process is cool. I like the approach when you actually see what is going on, instead of looking at some spinner for X minutes and be not sure if it is still processing or it is freezing. Simple and easy to use Edit mode. This is really cool product.
George Frigo
Lead product designer
Sivi.ai is an impressive tool that can significantly speed up your design workflow. Its ability to generate visuals in a variety of dimensions and the option to edit the designs make it a versatile option for anyone in need of appealing designs.

As per the tool - I've been looking for along time when there will be an AI tool to generate design from text with a user-friendly interface. And it seems like this is the one!
Oleksandr Naumov
Marketer
Loved the idea of providing a prompt template to help new users get the most out of their first tries! I was surprised by how complete this product is, being able to edit the content and the visuals separately is a really good idea.
