Feature Comparison
conceptviz
User-Friendly Interface
ConceptViz offers a simple, intuitive interface that allows users to sign in and select their subject matter effortlessly. This makes it accessible for educators and students with varying degrees of technical expertise, enabling them to focus on content rather than navigation.
Plain English Descriptions
Users can describe the diagrams they need in plain English, making the tool approachable for everyone. This feature eliminates the need for specialized terminology, allowing educators to express their ideas freely and receive tailored visuals based on their descriptions.
Projector-Ready Diagrams
All diagrams generated by ConceptViz are designed to be high-resolution and projector-ready. This ensures that visuals maintain clarity and legibility, from the front row to the back of the classroom, making it easier for students to engage with the material.
Subject and Grade Presets
ConceptViz includes quick presets for various subjects and U.S. grade bands, which facilitate the creation of diagrams specifically tailored to different educational levels. This feature allows educators to quickly generate relevant content without the need for extensive customization.
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.
Secure Share Links & Client Collaboration
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.

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.
