## Stitch

Stitch is Google's AI design experiment aimed at the front end of product work: turning an idea into a plausible interface fast. You describe the screen or app you have in mind, or supply a reference image or sketch, and Stitch generates multiple design variations. That makes it useful for early ideation when you want to see several directions before committing to one.

From there the workflow is conversational. You refine a chosen direction with follow-up prompts, adjusting layout, components, colors and theme, and Stitch re-renders the design. Because generation is quick, it works well for exploring mobile and web layouts side by side, or for quickly visualising an app concept during a meeting or spec discussion.

Stitch is built and operated by Google and sits alongside Google's other AI design experiments. Its strongest use is early-stage design ideation and rapid prototyping of interfaces rather than pixel-perfect production design. Availability, quotas and export options are set by Google and may change or be limited to certain regions or accounts.

**Pricing & Plans:** Freemium. Stitch is offered by Google with a free tier and usage limits; availability and quota details may vary by region or account. Check the official site for current access conditions.

- **Prompt to UI generation:** Describe an app screen in natural language and Stitch produces multiple complete UI designs, including mobile and web layouts.
- **Image and sketch input:** Upload a sketch, screenshot or existing screen and Stitch produces a matching design interpretation.
- **Fast iterative refinement:** Iterate with follow-up prompts to change layout, color themes and components without starting over.
- **Design-to-code handoff:** Move generated designs toward implementation with export options suited to design and development handoff.
- **Theme and style exploration:** Experiment with different themes and styles to explore multiple directions early in a project.

**Strengths:** Very fast way to visualise an app idea as a real interface; Generates multiple design variations at once for comparison; Supports both text prompts and image or sketch input; Backed by Google and integrates with design and dev handoff workflows

## UI Copilot (Design Copilot)

UI Copilot is a Chrome extension that turns your browser into a portable design review tool. Rather than copying screenshots into a chat window or waiting for a colleague's feedback, you click the extension icon, drag a selection box over any part of a page, and within seconds get a written list of suggestions about the layout, spacing, color scheme, typography, and overall usability of that region. Because it operates on a screen capture rather than page source, it works equally well on public websites, localhost, and internal development servers.

The extension follows a bring-your-own-key model: you supply a free Google Gemini API key, which is stored locally in the browser's sync storage and used only to make calls to the Gemini service. The product was free during its beta period with near-unlimited feedback requests, and it automatically falls back between the Gemini Pro and Flash models when rate limits are hit. That design keeps the tool free to use while letting advanced users control their own quota.

UI Copilot is aimed at anyone who cares about interface quality — professional designers wanting a second opinion, developers improving their UI instincts, entrepreneurs validating a landing page, or students learning design principles in context. Reviews on the Chrome Web Store are modest in number but positive, and the extension has a small, focused user base.

**Pricing & Plans:** Free. The extension is free to use and relies on a bring-your-own Google Gemini API key, so your only potential cost is whatever the Gemini API charges beyond its free tier. The developer offered the tool free of charge during its beta period.

- **Screen capture with drag-to-select:** Click, drag, and release over any region of a webpage to capture exactly the area you want reviewed.
- **Instant AI design critique:** Captured regions are analyzed by Google Gemini models and returned as a concrete list of design suggestions in seconds.
- **Works on localhost and dev servers:** Because it reviews what is rendered on screen, it functions on production sites, staging environments, and local development builds alike.
- **Bring-your-own API key security:** Your Gemini key stays in browser sync storage, accessible only to the extension, and is used solely for Gemini API calls.
- **Automatic model fallback:** The extension switches between Gemini Pro and Flash models when rate limits are reached so feedback keeps flowing.

**Strengths:** Completely free to use during the beta period; No account signup required — you only need a Google Gemini API key; Works on live sites, localhost, and internal dev servers; Key is stored locally in browser sync storage, not on a third-party server

**Limitations:** Requires you to obtain and manage your own Google Gemini API key; Feedback quality depends on the Gemini models and is limited by their free-tier rate limits; Small user base and modest review history make long-term maintenance uncertain
