Three products, one engine
Sivi has been the Large Design Model category creator.
Sivi API
For backend integration and automated pipelines.
Send a JSON request with your text prompt, content, brand kit, and output size. Get back a multi-layered design with every element individually addressable. Export as JSON, HTML, JPG, PNG, or PDF.
Best for: bulk generation, automated workflows, scheduled campaigns, server-side processing.
Sivi SDK
For user-facing design experiences.
Embed a complete design generator and editor inside your product. Your users type a prompt, get a design, edit any element, and export. White-label the entire experience with your brand colors, fonts, and logo.
Best for: client portals, SaaS embeds, seller dashboards, team design tools.
Sivi MCP
For AI agents and agentic workflows.
Connect any AI agent to Sivi through the Model Context Protocol. Your agent calls Sivi as a tool, generates layered designs mid-conversation, and returns results to the user. No custom integration code. Works with Claude, ChatGPT, Cursor, Windsurf, and any MCP-compatible client.
Best for: AI assistants, agentic workflows, copilot features, chat-based design generation.
What the output looks like
Other APIs return flat images or filled templates. Here's what changes when you integrate a design API instead.
Built for your platform
Sivi's design API automates design creation within platforms. Instead of relying on templates, Sivi uses its Large Design Model to produce fresh, professional layouts instantly. Each integration looks different. Here's what it looks like for yours.
Ecommerce platforms
Auto-generate product banners, category headers, and sale creatives for thousands of SKUs. One API call per product. Feed in your product data, get back layered banners.
Agencies
Build a white-label design studio for your clients. Each client gets their own portal with their brand kit. They self-serve on-brand designs within your guardrails.
LLM and AI products
Your AI agent writes the copy. Sivi composes the matching visual. Chain text generation and design generation in the same workflow. Use the MCP server so your agent calls Sivi directly as a tool, no glue code needed.

Common questions about the design API, SDK, and MCP
What is a design API?
A design API takes a text prompt, brand assets, and size specifications as input and returns a structured, multi-layered design as output. Every element (text, images, vectors, backgrounds) exists on its own layer and can be edited independently. It is different from an image generation API (which returns flat pixels) and a template API (which fills pre-made layouts). Read the full guide.
Is this a template-based system?
No. Every design is generated from scratch by Sivi's Large Design Model. No templates to build, manage, or maintain.
How to integrate Sivi API in your website or app?
Choose from client SDK, server APIs, or a mix of both. The SDK embeds a design studio in your frontend. The Core Design API gives you backend control. Most teams get up and running in as little as 60 minutes.
How is Sivi's design API different from image generation APIs?
Image generation APIs return flat pixels with no layers and no editable text. Sivi returns structured design files where every element is individually editable.
Can I use the API, SDK, and MCP together?
Yes. Many integrators use the API for high-volume automated generation (batch product banners, scheduled social posts), the SDK for interactive, user-initiated design (client self-serve, on-demand creation), and the MCP server so their AI agents can generate designs as part of agentic workflows.
Do I need the SDK, the MCP server, or is the API enough?
The API includes an anonymous design studio link for every generated design, your users can open it and edit the output (move elements, change text, export). What they cannot do with the API alone is work with the prompt or update the input. If your users need to generate designs themselves, control prompts, and manage the full input-to-output flow inside your product, you need the SDK. If you're building an AI agent or copilot that should generate designs as a tool call, use the MCP server.
What is the Sivi MCP server?
An MCP server that lets AI agents call Sivi as a tool during conversations and agentic workflows. Compatible with Claude, ChatGPT, Cursor, Windsurf, and other MCP clients.
What user management API options are available?
Three options: redirect users to create Sivi accounts, manage users programmatically via the API, or embed fully so users never leave your platform. User management docs
What enterprise API integration features are available?
White-labeling, custom themes, staging environments, dedicated support, custom feature development, and influence on the roadmap. Talk to sales
How is data secured during API interactions?
All API traffic is encrypted. Brand assets and generated designs are isolated per account and never used for model training.
Do I own the designs generated through the API?
Yes. Full IP rights stay with you. Sivi claims no ownership over your generated output or brand assets.
What languages are supported?
72+ languages including RTL scripts like Arabic, Hebrew, and Urdu. The layout is re-composed per language, not just text-swapped. Supported languages
