## Prototide

Prototide sits in the browser toolbar and works on whatever page you are already looking at. Instead of switching to a separate review tool or waiting for a teammate's comments, you open the extension, choose whether to review just the current viewport or the whole page, and fill in a short brief: who the page is for, what you want visitors to do there, and which design concerns matter most to you. The extension then produces clear, plain-language observations about hierarchy, clarity, spacing and other visible design issues.

The workflow is deliberately lightweight. Feedback arrives as a list you can read in context, save for later, and work through one item at a time. Because the analysis happens against the rendered page, the suggestions tend to reference concrete elements rather than abstract principles, which makes them easier to hand to a designer or to apply yourself during a quick iteration.

The extension is aimed at solo builders, small product teams and freelancers who want a fast second opinion before shipping. It is free to install, with optional in-app purchases for expanded use. Because the developer's domain no longer resolves and the most recent store update was in mid-2024, treat it as a stable but lightly maintained tool rather than a rapidly evolving platform.

**Pricing & Plans:** Free to install from the Chrome Web Store, with optional in-app purchases for additional features or usage. The listing does not publish specific tier prices, and the developer's pricing page is currently unreachable because prototide.app no longer resolves. Check the in-extension upgrade prompt for current amounts.

- **Screen or full-page review:** Choose a focused critique of the current viewport or a comprehensive pass over the entire page, depending on how broad you want the feedback to be.
- **Brief-driven analysis:** Supply the target audience, the desired action and your own design concerns so the generated feedback is tailored to the page's actual purpose.
- **Actionable in-browser insights:** Read suggestions without leaving the tab, so you can compare each point against the live design and decide what to change.
- **Saving feedback for later:** Keep the review output so you can work through items across multiple sessions or share the list with collaborators.
- **Privacy-conscious data handling:** The developer discloses handling of personally identifiable information and website content, and states that data is not sold to third parties.

**Strengths:** Works directly on any live page in Chrome, with no separate canvas or mockup needed; The audience, goal and concerns brief produces noticeably more relevant feedback than generic checklists; Feedback is saved and readable, making it easy to turn into a task list; Free to install, with upgrades only if you need more usage

**Limitations:** The developer's own site, prototide.app, no longer resolves, so support and documentation options are limited; No store ratings yet and a small install base, so there is limited community evidence about output quality; Updates have been infrequent, with the last published version dating to 2024

## 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
