Stitch 3.0 (New Upgrades): Google just COOKED with the New Stitch UI Designer UPGRADES!

Key Concepts

• Stitch by Google: An AI-first design environment for generating UI screens, importing Figma designs, iterating with prompts, and exporting code.
• Gemini 2.5 Pro: The advanced AI model powering Stitch's design agent, offering refined outputs, improved spacing, typography, and photo/font pairings.
• Variance: A feature allowing users to generate multiple alternate design variations of a screen without re-prompting.
• Canvas Generation: The ability to generate an entire user flow (multiple screens) at once, arranged as a flow.
• Organizer: A tool to clean and arrange messy canvases into a tidy grid.
• Multi-select and Batch Prompts: The capability to select multiple screens and apply a single prompt to all of them simultaneously for consistent updates.
• Sharing (Read-only Link): Allows anyone to view a project without logging in, facilitating client reviews and feedback.
• Follow-up Prompt Suggestions: AI-generated prompts that appear after a screen is generated, suggesting next steps to extend the project.
• Experimental Mode: Offers higher fidelity generations with the Gemini 2.5 Pro model, but with slightly less in-place tweakability compared to standard mode.
• Standard Mode: Provides quicker, more interactive options, especially for UI controls like color pickers.
• Privacy Toggle: A setting to disable model training for privacy-conscious users.

Stitch by Google: Recent Updates and Enhancements

This video details recent updates to Stitch by Google, an AI-first design environment, highlighting significant improvements that make it a more robust tool for rapid prototyping and design iteration. The core of these updates revolves around the integration of the Gemini 2.5 Pro model and the introduction of several new interaction-focused features.

1. Core Model Upgrade: Gemini 2.5 Pro

The most significant update is the tuning of Stitch's design agent to Gemini 2.5 Pro. This upgrade has led to demonstrably more refined outputs, with improvements in:

• Spacing: AI-generated layouts now exhibit more sensible and deliberate spacing.
• Typography: Font choices are more considered and professional.
• Photo/Font Pairings: The synergy between images and typography has noticeably improved.

The impact of this upgrade is described as moving away from "AI placeholder vibes" towards "real design intent." Stitch claims a significant user preference for these new results, a sentiment echoed by the presenter's personal experience.

2. Experimental Mode Enhancements

Experimental Mode has received substantial improvements, making it more practical for users:

• Increased Generations: Users now get a higher, "usable limit" of experimental generations per month.
• Gemini 2.5 Pro Access: This mode fully leverages the capabilities of the 2.5 Pro model.
• Translation Support: Added support for over 30 languages, beneficial for exploring multi-language product designs.

While Experimental Mode offers high-fidelity outputs, the presenter notes that Standard Mode still provides richer UI controls, such as color pickers, making it faster for immediate style adjustments. Experimental mode is ideal for higher fidelity generations but is currently less tweakable in place.

3. Key New Features for Enhanced Workflow

Several new features are highlighted as crucial for improving the design process:

• Variance:

  • Functionality: Users can click on any screen and generate multiple alternate design variations (different layouts, spacing, or styles) without needing to re-enter prompts.
  • Benefit: Accelerates the exploration of visual directions quickly.
  • Future Development: Custom prompts for variants are planned, allowing for targeted alternatives (e.g., "cleaner, minimal variant" or "bold, colorful variant").

• Canvas Generation:

  • Functionality: Enables the generation of an entire user flow (multiple screens) at once, rather than screen by screen. Stitch outputs a set of screens arranged as a flow, mimicking Figma's multi-frame approach.
  • Benefit: A significant time-saver for mapping product journeys, including the generation of realistic image assets.

• Organizer:

  • Functionality: A tool to clean and arrange messy canvases into a tidy grid with a single click.
  • Benefit: Indispensable for managing complex flows, allowing designers to focus on ideation rather than layout issues.

• Multi-select and Batch Prompts:

  • Functionality: Users can select multiple screens (by holding Shift) and apply a single prompt to all of them simultaneously.
  • Example: "Make primary buttons rounded and increase contrast" applied to all selected screens.
  • Benefit: Ensures consistency across the entire flow without manual repetition, a feature the presenter uses "all the time."

• Sharing (Read-only Link):

  • Functionality: Users can generate a read-only link to their project, allowing anyone to view it without needing to log in.
  • Benefit: Streamlines client reviews, QA processes, and quick feedback loops.
  • Future Development: This is seen as groundwork for a "remix flow," suggesting future collaborative features like forks and shared templates.

• Follow-up Prompt Suggestions:

  • Functionality: After a screen is generated, Stitch suggests follow-up prompts (e.g., "add settings screen," "create onboarding checklist").
  • Benefit: Keeps the creative flow going by providing immediate next steps and reducing the cognitive load of formulating new prompts.

4. Export Options and UI Polish

• Export: Designs can be exported as images or downloaded as HTML/Tailwind code. The Tailwind export is described as "nicely usable" with coherent and tweakable classes. While a direct React export is still desired, the Tailwind HTML is considered a good intermediate step for handoffs.
• In-app Preview: A full-screen preview and direct download button are available for quick asset retrieval.
• UI Polish: General improvements have been made across the UI, including smoother tooltips, a nicer layout, and fewer "janky bits" when switching screens.

5. Privacy Considerations

A privacy toggle is available in the settings to disable model training, catering to users who are privacy conscious.

6. Demo: Movie Tracker App

The presenter demonstrates the new features by creating a simple movie tracker app flow:

1. Initial Prompt: Using Experimental Mode with Gemini 2.5 Pro, the prompt was: "create a movie tracker app with authentication review screen and a dark theme option."
2. Flow Generation: Stitch generated multiple screens for the flow, showcasing realistic asset images, cleaner layouts, and nuanced typography.
3. Batch Prompt Application: All screens were selected, and a batch prompt was applied: "Make primary buttons pillshaped, increase CTA contrast, and use a warmer accent."
4. Result: Stitch applied these changes consistently across the entire flow in seconds, demonstrating the power of multi-select and batch prompts.

7. Conclusion and Call to Action

The presenter concludes that the combination of Gemini 2.5 Pro, Variance, Canvas Generation, Organizer, Multi-select, and improved Sharing makes Stitch feel significantly more "production ready." The tool is now faster for iterating ideas, maintaining consistency, and involving others without the overhead of extensive export/import processes. Users who may have tried Stitch previously and found it lacking are encouraged to revisit it to experience these new features.
