Google now has several AI tools that can help create interfaces, branded marketing content, images, video and even complete creative workflows. The confusing part is that these Google AI design tools overlap just enough to look interchangeable when they actually solve different problems.
The simplest way to understand the current lineup is this: Stitch is primarily for interface and software design, Pomelli is built around brands and marketing, and Flow is a broader AI creative studio for visual production. This guide explains what each tool does, where they overlap, what they still cannot replace and how to choose the right one for the project in front of you.
Use Stitch when you need to design an app, website interface, dashboard or other UI.
Use Pomelli when the job starts with a business, brand identity, campaign or marketing system.
Use Flow when the output is primarily images, video, editing or a broader custom creative workflow.
Do not choose by feature count. Choose according to the thing you are trying to produce.
1. What Are Google’s AI Design Tools?
“Google AI design tools” is best understood as an umbrella description rather than the name of one official product suite. Google’s AI ecosystem now contains multiple products that touch different parts of the creative process, from early interface concepts to branded marketing assets and visual production.
For most people exploring AI-assisted design, three products are especially useful to understand:
Best starting point: UI and interface design.
Apps Websites UI concepts PrototypesBest starting point: brands and marketing.
Brand identity Campaigns Brand books WebsitesBest starting point: visual creative production.
Images Video Editing WorkflowsGoogle also has tools such as Google AI Studio and Antigravity that become relevant when a project moves from designing toward building software. They are useful parts of the broader workflow, but they are not identical to Stitch, Pomelli or Flow.
2. Google AI Design Tools Compared
The most useful comparison is not “Which product has the most AI features?” It is which product begins closest to your actual problem.
| Google tool | Best for | Typical output | Good fit for |
|---|---|---|---|
| Stitch | UI and software design | App screens, website interfaces, dashboards, prototypes | Designers, founders, developers and product teams |
| Pomelli | Brand and marketing creation | Brand identity, campaign assets, brand books and websites | Small businesses, ecommerce sellers and marketers |
| Flow | Visual creative production | Images, videos, edits and custom creative workflows | Creators, marketers and visual production teams |
Think about the final artifact. If you need an interface, begin with Stitch. If you need a consistent business brand or campaign, investigate Pomelli. If you need image or video production, start with Flow.
3. What Is Google Stitch?
Google Stitch is an AI-native design canvas focused on software interfaces. Google describes it as a way to create, iterate and collaborate on high-fidelity UI using natural language.
Instead of beginning with an empty design canvas and manually constructing every screen, you can describe what you are trying to build, add context and iterate on the interface with AI assistance.
That makes Stitch especially relevant when the desired result looks like:
- an app screen;
- a website interface;
- a landing-page concept;
- a dashboard;
- a multi-screen user flow; or
- an early software prototype.
What changed with Stitch in 2026?
Google significantly expanded Stitch in 2026. The updated Stitch Agent can stream work onto the design canvas in real time, allowing users to steer the direction while it works instead of waiting for one finished result.
Google also says Stitch can accept text or voice instructions and use existing code and design files as context. When a design is ready to move beyond visual exploration, Google provides paths toward AI Studio, Antigravity and web publishing workflows.
That makes Stitch more interesting than a simple “prompt to mockup” generator. Its bigger idea is an ongoing AI-assisted design environment where you can explore, critique, revise and then move closer to implementation.

Who should consider Stitch?
Stitch makes the most sense when your blank page is an interface problem. A founder exploring an app idea, a designer testing several UI directions or a developer who needs an early interface concept may find it more directly relevant than a general image-generation tool.
It is less appropriate when your main goal is producing advertising creative, generating cinematic video or establishing an entire business brand.
What is DESIGN.md in Stitch?
One of Stitch’s more interesting ideas is DESIGN.md, an agent-friendly way to carry design-system rules between projects and tools.
Google open-sourced a draft DESIGN.md specification in April 2026. Rather than forcing an AI system to guess why a particular color, component or rule exists, the format is intended to make more design-system context explicit. Google also points to accessibility-rule validation as one potential use.
This matters because consistent AI-assisted design depends on more than generating attractive individual screens. A useful design system needs rules that stay consistent as a product grows.
See Google’s explanation of DESIGN.md.
4. What Is Google Pomelli?
Pomelli approaches design from a different starting point. Instead of asking primarily, “What interface should we make?”, it is designed around the needs of a business and its brand.
Google originally introduced Pomelli to help small and medium-sized businesses create on-brand content. Its newer agentic capabilities can help build what Google calls a Business DNA or brand identity using existing materials or information supplied through conversation.
Once that brand foundation exists, Pomelli can use it to support additional work such as:
- brand identity development;
- on-brand marketing content;
- campaign assets;
- brand books;
- product-focused creative; and
- website creation.
Who should use Pomelli?
Pomelli is especially interesting for small-business owners and marketers who repeatedly run into the same problem: individual pieces of creative may look fine on their own, but the overall brand does not feel consistent.
The underlying goal is not simply “generate another image.” It is to give the AI more context about the business so future outputs have a better chance of following the same visual and marketing direction.
Stitch starts with: What interface should we design?
Pomelli starts with: What does this business and brand need to communicate?

5. What Is Google Flow?
Google Flow needs a particularly careful explanation because its role has expanded.
Flow originally arrived with a strong filmmaking focus, but Google now describes it more broadly as an AI creative studio. Its capabilities include image and video generation, visual editing and increasingly customizable creative workflows.
Flow therefore makes more sense when your creative problem centers on visual media rather than interface structure or brand-system management.
Examples include:
- generating visual concepts;
- creating or refining images;
- generating video;
- editing visual content through AI-assisted workflows;
- experimenting with multimodal creative work; and
- building custom creative tools or workflows.
Google’s 2026 Flow update also introduced Gemini Omni capabilities and described ways for creators to build bespoke workflows using natural-language instructions.
That custom-workflow direction is important. It moves Flow beyond being only a place where you enter a prompt and receive a media file. The larger opportunity is to connect multiple creative steps into a repeatable process.

If you are creating AI-generated visual assets for different platforms, decide the output shape before generation. Our AI image aspect ratio guide explains how ratios change the way an image should be composed.
6. Stitch vs. Pomelli vs. Flow: Which One Should You Use?
You do not need to memorize every feature. Start with the problem you are trying to solve.
| I want to… | Best starting point | Why |
|---|---|---|
| Design an app interface | Stitch | The problem is primarily UI and product design. |
| Prototype a website interface | Stitch | Stitch is designed around interface creation and iteration. |
| Create a brand identity | Pomelli | Pomelli is built around business and brand context. |
| Create a brand book | Pomelli | Brand books are part of Pomelli’s current workflow. |
| Create marketing assets consistently | Pomelli | The goal is consistent branded communication. |
| Generate or edit images | Flow | The job centers on visual creative production. |
| Create AI video | Flow | Flow has dedicated video-generation and editing capabilities. |
| Build a custom creative workflow | Flow | Flow is increasingly designed for broader customizable creative processes. |
Notice that there is no honest “best overall” answer. A tool can be more powerful on paper and still be the wrong choice if it starts too far away from the output you actually need.
7. Three Practical Google AI Design Workflows
Individual tool descriptions become much easier to understand when you see how they fit into an actual process.
Idea to app or website
Idea → Stitch → UI iteration → development workflow
Begin with the product idea and user objective. Use Stitch to explore interface directions, refine the screens and then move toward development once the visual direction is strong enough.
Brand to campaign
Business → Pomelli → Business DNA → branded assets
Start with the business, existing brand materials and positioning. Build a clearer brand foundation before generating repeated campaign or website assets.
Brief to visual production
Creative brief → Flow → generate → edit → reuse workflow
Begin with a clear creative brief, create the visual media, refine the strongest outputs and turn repeatable steps into a more structured production workflow.
8. A Simple Google AI Design Tool Decision Framework
If you are still undecided, use these four questions.
1. Is the final output primarily an interface?
Start with Stitch.
2. Is the main problem brand identity or marketing consistency?
Start with Pomelli.
3. Is the final output mainly images or video?
Start with Flow.
4. Do you ultimately need working software rather than only a design?
Use the most appropriate design workflow first, then move into development and testing rather than assuming the generated design itself is production-ready.
This framework is deliberately simple. The products will continue to change, but the reader’s underlying problem is more stable.
9. What Google’s AI Design Tools Still Don’t Replace
AI can dramatically reduce the time required to explore ideas and produce early versions, but faster generation does not remove the need for judgment.
Do not treat AI-generated design as automatically production-ready. The faster AI makes creation, the more important it becomes to separate generation from approval.
10. Can You Combine Stitch, Pomelli and Flow?
Yes. In fact, thinking of the products as mutually exclusive may be unnecessarily limiting.
A business could use Pomelli to clarify brand direction, Stitch to explore the interface of a digital product and Flow to produce supporting visual media. The useful question is not whether one Google tool should do everything. It is whether combining tools removes real friction from the workflow.
Avoid using extra AI tools simply because they are available. Every additional tool introduces more handoffs, more versions and more things that can become inconsistent.
A good workflow is usually the smallest reliable combination of tools that gets from idea to finished output.
11. Are Google’s AI Design Tools Free?
Availability, usage limits, geographic access and subscription requirements can change as Google updates its AI products. Some capabilities may also depend on the Google AI plan, model or platform being used.
For that reason, do not choose one of these tools based on an old article that permanently labels it “free” or assigns a fixed feature limit. Check the current Google product page before making a decision based on pricing or availability.
You can review Google’s current experimental AI products directly through Google Labs.
12. Which Google AI Design Tool Is Best?
There is no single best Google AI design tool for every project.
Stitch is the strongest starting point when the output is an interface. It is designed around turning ideas and context into software UI that can be explored and iterated.
Pomelli is the stronger fit when the project begins with a business or brand. Its value comes from establishing brand context and using that foundation across marketing assets, brand books and websites.
Flow is the stronger fit when the project centers on visual creative production. Images, video, editing and custom creative workflows are closer to its core role.
Choose based on what you want to create, not on which Google AI tool has the longest feature list. That one rule makes the current Google design ecosystem much easier to understand.
13. Frequently Asked Questions
What are Google’s AI design tools?
Google has several AI products that support different parts of design and creative work. Stitch focuses on UI and software design, Pomelli focuses on branding and marketing, and Flow focuses more broadly on image, video and creative production workflows.
Is Google Stitch an AI design tool?
Yes. Google describes Stitch as an AI-native software design canvas that can turn natural-language instructions and other project context into high-fidelity UI that users can iterate and collaborate on.
What is the difference between Stitch and Pomelli?
Stitch is primarily centered on designing software interfaces, while Pomelli is centered on businesses, brand identity and marketing content. Choose Stitch when the problem is UI; choose Pomelli when the problem is branding or marketing consistency.
What is the difference between Stitch and Google Flow?
Stitch is mainly an interface-design environment. Flow is a broader visual creative studio for generating and editing images and video and for building creative workflows. They can be complementary rather than direct substitutes.
Can Google AI create website designs?
Yes. Stitch can be used to explore website and interface designs, while Pomelli’s newer capabilities include website creation tied to business and brand context. The better option depends on whether your priority is interface design or branded business content.
Which Google AI tool is best for graphic design?
For general visual creative involving generated or edited imagery, Flow is usually the closest fit among these three. For branded marketing assets, Pomelli may be more appropriate because it starts from business and brand context.
Which Google AI tool is best for UI design?
Stitch is the clearest fit for UI design because Google has developed it specifically as an AI-native software design canvas for creating and iterating on interfaces.
Can Google’s AI design tools replace professional designers?
They can automate or accelerate parts of ideation and production, but generated work still needs judgment, accessibility review, technical testing, brand decisions and final quality assurance. The strongest use is usually AI-assisted design rather than unreviewed AI output.
14. Final Takeaway
Google’s AI design ecosystem makes more sense when you stop treating every product as a competitor.
Stitch solves an interface problem. Pomelli solves a brand and marketing problem. Flow solves a broader visual creative-production problem.
Start with the outcome you need, choose the tool that begins closest to that outcome and keep human review between generated work and anything you publish, ship or sell.
