Feature Comparison

Proofapp

Visual Commenting

This core feature allows any stakeholder to click directly on a live screenshot of a webpage to leave precise, pinned feedback. This eliminates the confusion of written descriptions like "top left, under the navigation" by providing exact visual context for every comment. Users can start threaded discussions, mention teammates, and ensure all communication is tied directly to the relevant design element, making feedback loops dramatically more efficient and clear for everyone involved.

Multi-Breakpoint Testing

Proofapp automatically captures and presents screenshots of any submitted URL at both desktop and mobile viewports. This allows designers, developers, and clients to review and provide feedback on how a website or application renders across different devices simultaneously. It ensures that responsive design issues are caught and discussed early in the feedback process, preventing costly fixes later in development and guaranteeing a consistent user experience.

Projects can be shared effortlessly with clients or external stakeholders via secure, expirable links. The revolutionary aspect is that reviewers do not need to create a Proofapp account to view projects or leave comments, drastically reducing friction in the feedback collection process. This feature provides a professional, branded experience for clients while giving project owners full control over access and visibility.

Real-Time Collaboration Dashboard

All feedback is centralized in a live project dashboard where team members can see comments as they are posted. This facilitates immediate discussion, allows users to reply in threads, attach supporting files (like images or documents), and mark feedback items as resolved. Coupled with real-time notifications and Slack integration, this ensures the entire team stays aligned, progress is tracked transparently, and no feedback gets lost in siloed communication channels.

Refbox

Always-on-Top Floating Frames

This is the cornerstone feature of Refbox. Users can pin any image, video, GIF, or note into a resizable frame that floats above all other application windows. This ensures your reference material is always visible right beside your working canvas, whether you're in Photoshop, Blender, or a code editor. Frames can be minimized, locked in place, or auto-hidden to clean up your workspace, providing ultimate control over your desktop real estate and focus.

Comprehensive Media Support & Organization

Refbox supports a wide array of media types beyond standard images. You can import and view videos, animated GIFs (with playback controls), SVG files, and even take instant website screenshots by pasting a URL. All media is organized into customizable Collections within a sidebar, allowing you to separate references by project, client, or theme. Drag-and-drop makes building and managing these collections intuitive and fast.

Advanced Creative Utilities

The app includes a suite of specialized tools that cater to professional creative needs. This includes a color picker to sample colors directly from any reference media, an image cropper to focus on specific details, and pixel rendering mode for authentic pixel art viewing. For motion work, you can scrub through GIFs frame-by-frame. Notes support Markdown formatting and checklists, making it easy to add textual context or task lists alongside visual inspiration.

Streamlined Workflow Shortcuts

Refbox is designed for keyboard-driven efficiency. You can quickly swap between floating references using arrow keys, change collections with a single click, and use customizable global shortcuts to show, hide, or manipulate frames without touching the mouse. These little touches, like copying media to the clipboard or saving it directly to your system, save countless clicks and hours over a long project, keeping you in a productive rhythm.

Use Cases

Proofapp

Freelancer Client Approvals

Freelancers can use Proofapp to present website designs or developments to clients in a professional, organized manner. Instead of exchanging dozens of emails with attached, annotated screenshots, they share a single Proofapp link. Clients can click to leave clear, visual feedback directly on the design, which the freelancer can then address systematically. This streamlines the revision process, reduces miscommunication, and projects a highly professional image, saving hours per project.

Agency Design Team Workflow

Design agencies managing multiple clients and complex projects utilize Proofapp to consolidate internal and external feedback. Internal teams can conduct design reviews using visual comments before sharing a polished version with the client. The platform handles multiple page reviews within a single project, keeping all feedback for a website redesign or campaign launch organized, actionable, and accessible to all relevant team members, improving internal alignment and client satisfaction.

Marketing Team Landing Page Reviews

Marketing teams launching new campaigns can use Proofapp to gather precise feedback on landing pages from copywriters, designers, product managers, and legal teams. Stakeholders can pin comments on specific headlines, images, or call-to-action buttons, ensuring every element is reviewed in context. This visual collaboration prevents last-minute changes and ensures the final page aligns perfectly with the campaign strategy before it goes live, increasing conversion effectiveness.

Development Team QA and Bug Reporting

Development teams can leverage Proofapp as a visual bug reporting and quality assurance tool. Instead of writing lengthy bug reports describing UI issues, testers and product managers can capture the live site URL, pin comments directly on the problematic element, and attach console logs or other files. This provides developers with exact visual context and all necessary details to reproduce and fix issues quickly, accelerating the development cycle.

Refbox

Digital Illustration & Concept Art

Illustrators and concept artists can gather mood boards, anatomical references, color palettes, and style inspirations into dedicated Refbox collections. By floating these references over applications like Photoshop or Clip Studio Paint, artists can constantly view their guides without breaking concentration. The color picker and zoom features allow for precise color matching and detail study directly from the floating frames.

UI/UX & Graphic Design

UI/UX designers and graphic designers use Refbox to keep brand guidelines, competitor screenshots, typography samples, and layout inspirations instantly accessible. While designing in Figma or Adobe XD, having logos, color hex codes, and component libraries pinned on-screen ensures design consistency and speeds up the iteration process, eliminating the need to search through files or browser tabs.

3D Modeling & Animation

For 3D artists and animators, Refbox is ideal for holding character turnarounds, texture references, environment concepts, and motion study videos. The ability to play video references or scrub through GIFs frame-by-frame in a floating window is invaluable for replicating complex movements and poses in software like Blender or Maya, all while keeping the main viewport uncluttered.

Photography & Mood Boarding

Photographers and art directors can use Refbox to compile shot lists, lighting setups, composition examples, and model poses. The app functions as a dynamic, always-visible mood board during shoots or editing sessions in Lightroom. The notes feature is perfect for adding shot details or client feedback right next to the corresponding visual reference.
