One API call. Layered, editable, on-brand output. Real text you can click and change. Every element on its own layer. Not a template fill. Not a flat image from a diffusion model. A complete design your users can actually work with. Sivi gives you three ways to add a design API to your product: a REST API for backend automation, an SDK that drops a full design studio into your frontend, and an MCP server that lets any AI agent generate designs.

Sivi has been the Large Design Model category creator.
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.
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.
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.
Other APIs return flat images or filled templates. Here is what changes for your product when you integrate a design API instead.
| Feature | Sivi Design API | Image APIs | Template APIs |
|---|---|---|---|
| User experience | Users generate, edit, and export designs without leaving your product | Users get a static image to download | Users fill pre-made slots |
| Your engineering effort | One integration, zero template maintenance | Prompt-tuning per use case, custom post-processing | Build every template, update when designs change |
| Adding a new content type | Same API call, different prompt | Retrain or hope the model generalizes | New template per content type |
| Adding a new language | One parameter change, layout re-composed | English-only or separate pipelines | Separate template per language |
| Adding a new size | One parameter change, layout re-composed | Crop or regenerate | New template per size |
| AI agent support | Native via MCP server, zero glue code | Build your own integration | Build your own integration |
| Time to first integration | Under 60 minutes with SDK, under a day with API | Varies widely | Days to weeks per template set |
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.
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.
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.
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.
Your users stay in-platform at the creative stage. They generate ad creatives instantly instead of dropping off to design somewhere else. All IAB sizes. A/B variations on demand.
Users generate branded social posts, stories, and reels covers without switching to an external tool. Every post matches their brand kit.
Brand governance at scale. The API enforces your brand kit across thousands of creatives, 72+ languages, any channel. The SDK gives regional teams self-serve access.
Add a Generate Banner button to your page editor. Hero banners, hello bars, blog covers, on demand.
Automate daily content production. Generate professional marketing designs in 72+ languages at publishing speed.
Generate email headers and newsletter visuals that match the campaign content. Output exports as HTML.
Explore the output. The response includes an array of variant objects containing URLs and links to an anonymous design studio where you can view, edit, and export the generated designs.
Decide your integration path. API only? SDK embed? MCP for your AI agent? Mix and match. Pick the plan that fits.

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.
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.
Really great tool, game-changer that disrupts a huge market and everything connected with design and content creation.
I am an early beta user of Sivi and I love its present and future. I love the deep thought the team has put in it to understand the design process and making it business owner savvy. This is transformational for our GTM to help us quickly have multiple options in design for our messaging.
As per the tool - I’ve been looking for a long 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!
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.
