Feature Comparison
Opal44
Plain English Insights
This foundational feature connects directly to a user's GA4 account and interprets the raw data, providing explanations in simple, everyday language. Instead of presenting confusing metrics like "bounce rate" or "session duration" in isolation, Opal44's AI explains what these numbers actually mean for the business, such as identifying which pages fail to engage visitors or which traffic sources deliver the most valuable users. It eliminates the guesswork and technical jargon, making sophisticated analytics accessible to everyone on the team.
Conversation-Style Reports
Opal44 delivers analytics updates and reports in a format that mimics a natural conversation with a knowledgeable guide. This approach transforms dry data summaries into engaging, easy-to-digest narratives. Users receive insights that read like a chat, highlighting key trends, anomalies, and performance summaries in a clear and straightforward manner. This style enhances comprehension and ensures that critical findings are communicated effectively to all stakeholders, regardless of their analytical background.
Smart, Data-Driven Tips
Beyond simple explanation, Opal44 provides tailored, actionable recommendations backed by the user's specific GA4 data. The AI analyzes performance patterns to offer concrete suggestions for improvement, such as optimizing underperforming pages, capitalizing on high-traffic sources, or improving conversion funnels. These tips are designed to help users actively improve website traffic, enhance user engagement, and boost overall business results based on empirical evidence from their own analytics.
Real-Time Alerts
This proactive monitoring feature notifies users immediately when significant changes occur in their GA4 data. Opal44 tracks metrics for unusual spikes or drops in traffic, sudden changes in user behavior, or conversion rate anomalies. By providing real-time alerts, the platform ensures that users are always informed of critical events, allowing them to respond quickly to opportunities or address potential issues before they impact business performance negatively.
Proofapp
Visual Commenting
This foundational feature allows users to click directly on any area of a captured website screenshot to leave precise, contextual feedback. By pinning comments visually, it completely eliminates the guesswork and lengthy descriptions common in email or chat (e.g., "top left, under the navigation"). Each comment initiates a thread where team members and clients can reply, fostering clear and focused discussions tied directly to the design element in question, ensuring everyone is literally on the same page.
Multi-Breakpoint Testing
Proofapp automatically captures and presents screenshots of the submitted website at both desktop and mobile viewports simultaneously. This feature is critical for modern web development and design, allowing teams to review and collect feedback on a site's responsiveness and user experience across different devices within a single project. It ensures that visual and functional issues are caught and addressed for all breakpoints, not just a single screen size.
Secure, Account-Free Sharing
Project owners can generate secure, shareable links to send to clients and stakeholders for review. A significant advantage is that recipients can view the project and leave detailed feedback without the friction of creating a user account or remembering a password. These links can also be set to expire, providing control over access. This streamlines the client onboarding process and encourages faster, more direct participation in the feedback cycle.
Real-Time Collaboration & Notification
All activity within a Proofapp project is synchronized in real-time. When a new comment is pinned or a thread is updated, team members see the changes instantly without needing to refresh the page. Coupled with integrated real-time notifications and Slack integration, this feature ensures that feedback loops are tight and that no comment goes unnoticed, enabling dynamic, live collaboration that mimics an in-person review session.

Frequently Asked Questions
Opal44 FAQ
How does Opal44 connect to my Google Analytics data?
Opal44 connects to your Google Analytics 4 (GA4) property through a secure, code-free, and read-only OAuth integration. This means you grant Opal44 permission to access your GA4 data for analysis without it being able to alter any settings or data within your Google Analytics account. The setup process is designed to be completed in just a few minutes, requiring no technical coding or complex configuration.
What are "credits" in the pricing plans?
Credits in Opal44's pricing model represent units consumed each time you use the AI to generate an insight, report, or recommendation. One credit is typically used per AI action, such as asking a question about your data or generating a summary report. Plans offer a monthly allowance of credits (e.g., 5,000 or 10,000), with higher-tier plans providing more capacity for frequent, in-depth analysis and user queries.
Is my GA4 data secure with Opal44?
Yes, data security and privacy are paramount for Opal44. The platform employs enterprise-grade security measures for data transmission and storage. Your GA4 data is used solely to generate your insights and is never sold, shared with third parties, or used to train public AI models. You retain complete ownership and control of your data at all times, aligning with standard data protection principles.
Can I use Opal44 with multiple GA4 properties or accounts?
Capabilities depend on your chosen plan. The Starter plan typically supports connection to one analytics account. The Professional plan offers support for unlimited Google Analytics accounts at the Account level, making it suitable for agencies or businesses managing multiple properties. The Agency plan provides fully customizable solutions for complex, large-scale deployments with numerous properties and users.
Proofapp FAQ
How does Proofapp capture website screenshots?
Proofapp uses a secure, automated system to render and capture the webpage at the URL you provide. It processes the site to generate high-fidelity screenshots at predefined desktop and mobile breakpoints, ensuring an accurate visual representation for review. The process is typically completed within seconds, and the screenshots are stored securely within your project for your team and clients to annotate.
Do clients or reviewers need an account to give feedback?
No, one of Proofapp's key features is that reviewers do not need to create an account. Project owners simply generate a secure, shareable link and send it to their clients or stakeholders. Recipients can click the link, view the project, and immediately start leaving visual comments and participating in threads, making the feedback process incredibly frictionless and accessible.
Can I use Proofapp for websites that are not live or are behind a login?
The standard capture process requires a publicly accessible URL. For sites in development on localhost, staging servers, or behind authentication, Proofapp may not be able to capture them automatically. In such cases, users often manually upload full-page screenshots or use browser extensions to facilitate the review process, though native support for password-protected staging sites may be a feature under consideration.
What kind of integrations does Proofapp support?
Proofapp offers direct integration with Slack to send real-time notifications about new comments and project activity directly into your team's channels. This helps keep everyone informed without needing to constantly check the Proofapp dashboard. The platform is designed with an API-forward approach, suggesting potential for future expansions and custom integrations with other project management and development tools.
