Ninjasell

Proofapp
Visual Commenting
This is the heart of Proofapp's collaborative power. Instead of describing issues with words like "top left, under the nav," team members and clients can click directly on any element of the captured screenshot to leave a pinned comment. This visual context eliminates all guesswork and misinterpretation, ensuring feedback is precise and immediately understandable. Each comment initiates a thread where collaborators can reply, ask clarifying questions, and attach relevant files, creating a complete, actionable history for every piece of feedback directly where it matters.
Multi-Breakpoint Testing & Capture
Proofapp understands that modern websites must work across devices. When you provide a URL, the platform automatically captures and presents screenshots of your site at both desktop and mobile breakpoints. This allows for comprehensive review and ensures feedback is relevant to all user experiences. Teams can seamlessly switch between views to leave contextual comments on each version, guaranteeing that design and functionality issues are caught and resolved for every critical screen size in one unified review session.
Real-Time Collaboration & Notifications
Feedback loops move at the speed of your team's collaboration. Proofapp provides a real-time dashboard where all project participants can see new comments, replies, and resolutions as they happen, without needing to refresh the page. Integrated notifications keep everyone in sync, whether they are in the app or connected via Slack. This live, cooperative environment accelerates decision-making, prevents duplicate feedback, and creates a transparent record of the review process from first comment to final approval.
Secure, Client-Friendly Sharing
Collaboration extends effortlessly to clients and external stakeholders. Project owners can generate secure, shareable links to the review workspace. These links can be set to expire for added security, and crucially, reviewers do not need to create a Proofapp account to participate. This frictionless access lowers barriers for client feedback, making it easy for them to contribute visually and contextually while maintaining control and organization for the core team, all within a professionally branded environment.
Use Cases

Quick Launch for New Sellers

Reviving Stagnant Listings
For sellers with listings that have not sold for an extended period, NinjaSell's ReSpark feature brings a lifeline by automatically updating titles and tags. This helps ensure that even previously stagnant products have a chance to gain traction.

Hands-Free Marketing with Pinterest Auto-Poster
Sellers can leverage the Pinterest Auto-Poster to automatically publish their products to relevant boards, driving organic traffic to their Etsy shops. This feature allows sellers to market their products effortlessly, enhancing visibility without additional effort.
Proofapp
Streamlining Client Feedback for Freelancers
Freelancers can present a supremely professional front to their clients while saving hours of administrative work. Instead of exchanging confusing emails with attached, annotated screenshots, they share a single Proofapp link. Clients click directly on the design to leave clear, pinned feedback. This collaborative approach reduces back-and-forth by an average of 60%, impresses clients with a modern workflow, and allows the freelancer to focus on executing revisions rather than deciphering them.
Managing Cross-Functional Website Reviews
When launching a new landing page or campaign, marketing, design, and development teams need to align quickly. Proofapp serves as the single source of truth for all visual feedback. Marketers can comment on copy and layout, designers on UI elements, and developers on technical implementation—all in one visual space with comments pinned to the exact location. This synergy breaks down departmental silos, ensures nothing is lost in translation, and accelerates the path to a polished, approved launch.
Accelerating Design-Developer Handoff
The transition from design mockup to live website is a critical phase often fraught with miscommunication. Using Proofapp, developers can review the live staging URL directly. They can pin questions or flag implementation issues visually on the actual build, and designers can respond with clarifications or approvals right on the element in question. This visual, collaborative dialogue ensures the final product matches the design intent perfectly, reducing costly post-launch fixes.
Conducting Efficient Quality Assurance (QA) Testing
QA testers and project managers can use Proofapp to document bugs and issues with unparalleled clarity. Instead of writing lengthy reports describing a bug's location and behavior, testers can capture the page state and click directly on the problematic button, image, or text to log the issue. They can attach console logs or additional screenshots to the comment thread. This creates a visual, organized bug tracker that developers can immediately understand and act upon, streamlining the entire QA process.

Proofapp FAQ
Do reviewers or my clients need an account to give feedback?
No, one of Proofapp's core collaborative features is its client-friendly access. You can share a project via a secure, expirable link. Anyone with that link can view the screenshots and leave comments, pin feedback, and participate in threads without ever needing to sign up for an account. This removes a significant barrier to entry and makes collecting external feedback incredibly simple and efficient.
How does Proofapp capture screenshots of my website?
The process is designed for team efficiency. You simply paste the public URL of your website (either a live site or a staging environment) into Proofapp. Our system then automatically visits that URL and captures full-page screenshots at pre-defined desktop and mobile breakpoints. This happens in seconds, allowing your team to move immediately into the collaborative review phase without any manual screenshotting or uploading.
Can I use Proofapp for private or localhost websites?
Proofapp is built for collaboration on publicly accessible projects. The automatic screenshot capture system requires a publicly accessible URL to function. For websites on a local development environment (localhost) or behind a secure login, the system cannot access the content to capture it. For these private projects, teams typically use a public staging server for the review and feedback phase.
How does Proofapp support real-time collaboration?
Proofapp creates a synchronized workspace for all project participants. When one person leaves a comment or replies to a thread, that activity appears instantly for everyone else who has the project open. There is no need to refresh the page. This live updating, combined with optional email and Slack notifications, ensures your team stays in perfect sync, enabling fast, cooperative decision-making and eliminating the lag of asynchronous communication.
