Feature Comparison

Mailopoly

Cleanbox AI Inbox Management

Mailopoly's Cleanbox feature acts as an intelligent gatekeeper for your attention. From day one, with zero manual setup or complex rules, its AI accurately identifies and surfaces only the emails that truly matter—like urgent messages from your boss or time-sensitive delivery updates—while quietly filtering out promotional noise and low-priority correspondence. It learns your preferences with a single tap, ensuring your notifications are reserved for genuine priorities, dramatically reducing daily distractions and creating a consistently organized, manageable inbox that promotes focus instead of overwhelm.

Poly - Your Integrated AI Life Assistant

Poly is more than a chatbot; it's a personal executive assistant built directly into your inbox with full context of your account. You can ask Poly natural questions like "What do I need to pay this week?" or "Summarize emails from my accountant," and it will provide instant, accurate answers. It manages your life admin by tracking shipments with full timelines, monitoring upcoming events, and helping you manage personal finances. This deep integration means you get actionable insights and summaries without ever needing to open multiple emails or apps.

AI-Powered Reply Drafting

This feature eliminates the friction of composing responses. Mailopoly's AI doesn't just generate generic replies; it analyzes your writing style and history to draft emails that sound authentically like you. Whether for personal notes, work correspondence, or side-hustle communications, it provides multiple tone-appropriate suggestions instantly. You simply review, make minor edits if desired, and send—turning the tedious task of email writing into a quick decision-making process, saving significant time and mental energy.

Intelligent Unsubscriber & Email Tracker

Mailopoly tackles inbox clutter at its source with an instant unsubscriber that actively and reliably removes you from unwanted mailing lists, not just moving them to spam. Complementing this is a powerful email tracker that provides full transparency on your sent messages, showing you exactly who opened them, how many times, and their geographic location. This suite of tools gives you unprecedented control over both incoming noise and outgoing communication effectiveness.

SupaSidebar

Universal Menubar Sidebar

SupaSidebar transforms your macOS menubar into a powerful, Arc-inspired command center. This elegantly designed panel provides instant, one-click access to your saved links, files, folders, and open browser tabs from any application. It consolidates disparate elements of your workflow into a single, distraction-free interface, eliminating the need to hunt through Finder windows or browser bookmarks. The sidebar is always accessible but never intrusive, living discreetly in your menubar until summoned.

Global Keyboard Shortcuts

The app is built for speed, powered by a suite of intuitive global keyboard shortcuts that work from anywhere on your Mac. Save the current website link with CMD+CTRL+S or copy it with CMD+CTRL+C directly to the sidebar. Instantly open the search panel with CMD+CTRL+K to find any file, folder, website, or app. These shortcuts are designed to minimize mouse travel and context switching, allowing you to execute commands and retrieve information without breaking your concentration or leaving your current application.

Privacy-First, On-Device Storage

SupaSidebar is engineered with a fundamental commitment to user privacy. All your data—every saved link, file path, and organizational structure—resides securely on your Mac. Nothing is sent to external servers or cloud storage unless you explicitly choose to sync via iCloud. This approach ensures your sensitive work materials, research, and personal references remain completely under your control, offering peace of mind alongside powerful functionality.

Intelligent Organization with Spaces & Recents

Organize your digital assets into customizable "Spaces" for different projects, contexts, or workflows. The free plan includes 3 spaces, perfect for daily use, while Pro unlocks unlimited organization. Furthermore, the "Recents" feature automatically tracks every website you've used in the last 48 hours, creating a dynamic, searchable history that helps you instantly find work you were just viewing, preventing valuable links from getting lost in a tab avalanche.

Use Cases

Mailopoly

The Overwhelmed Professional & Parent

For individuals balancing a demanding career with family life, Mailopoly is a lifeline. It automatically filters out internal company newsletters and promotional blasts, ensuring notifications only come through for critical emails from a child's school, a partner, or an urgent work client. Poly can instantly find that buried flight confirmation or invoice, while the automated reply drafting handles quick confirmations during a busy day. This use case is about reclaiming mental space and ensuring nothing important slips through the cracks amidst the chaos.

The Entrepreneur & Side-Hustler

Managing multiple income streams means managing multiple email accounts and communication channels. Mailopoly consolidates everything—Gmail for the main business, Outlook for a freelance gig, a custom domain for a side project—into one clear dashboard. The AI extracts key tasks and deadlines from client emails, tracks shipments for product-based hustles, and helps draft professional replies in the appropriate voice for each venture. It turns a scattered operation into a centralized, manageable command center.

The Frequent Traveler & Event Planner

For those constantly on the move or organizing events, details are everything. Mailopoly automatically extracts booking confirmations, check-in times, gate information, and hotel details from emails, presenting them in an easy-to-scan format. The integrated event manager allows for sending custom invitations and tracking RSVPs seamlessly. Poly can answer "What are my upcoming trips?" or "When does my package arrive?" instantly, making travel and event coordination remarkably smooth.

The Privacy-Conscious User Seeking Efficiency

This user is tired of fragmented tools and values security alongside smart features. Mailopoly appeals by offering a SOC 2 certified, privacy-first platform that works with existing email providers without requiring data migration. The intelligent unsubscriber reduces exposure to marketing trackers, while the all-in-one functionality of Poly—handling tasks, summaries, and Q&A—means less data is spread across disparate, less secure apps. It's a single, secure solution for comprehensive life management.

SupaSidebar

The Multitasking Professional

For professionals juggling multiple projects, clients, and communication platforms, SupaSidebar acts as a central nervous system. Quickly switch between project-specific spaces containing relevant documents, dashboards, and communication links. Use global search to pull up a contract, a Slack channel, and a project management board in seconds, all without leaving your email client. This drastically reduces costly context-switching and keeps all project assets organized and immediately accessible.

The Researcher and Creator

Researchers, writers, and content creators who constantly gather sources, references, and assets will find SupaSidebar indispensable. Save article links, PDFs, image folders, and inspiration websites directly from the browser with a single shortcut. Organize them into spaces for different articles or projects. The "Recents" feature is a lifesaver for retracing your digital steps through hours of research, ensuring no critical source is ever lost in a sea of tabs.

The Tab-Hoarder and Bookmark Collector

For users who habitually have dozens of browser tabs open or maintain a sprawling, unmanageable bookmark bar, SupaSidebar offers liberation. It provides a structured way to save important links without the performance hit of keeping tabs open. Pin favorite items to the top for daily use and let less urgent links reside in an organized, searchable list. This clears mental and digital clutter, leading to a calmer, more focused computing experience.

The Efficiency Enthusiast

Anyone looking to streamline their Mac workflow and reduce repetitive actions will benefit. SupaSidebar eliminates the tedious process of manually navigating to frequently used files or typing out often-visited URLs. By making these resources accessible via consistent keyboard shortcuts from any app, it turns complex navigation tasks into simple, muscle-memory commands, saving countless clicks and minutes throughout the day.

Frequently Asked Questions

Mailopoly FAQ

How does Mailopoly work with my existing email accounts?

Mailopoly connects securely to your existing email accounts—including Gmail, Outlook, Yahoo, Hotmail, and any IMAP provider—using standard, secure authentication protocols. It acts as a client, meaning your emails remain on your provider's servers. Mailopoly simply reads, organizes, and presents them intelligently in its interface. You can also get a private @mly.life address. There is zero migration needed; you keep all your accounts and can manage them from one unified dashboard.

Does the AI really sound like me when drafting replies?

Yes. Mailopoly's AI is designed to analyze your unique writing style, including your common phrasing, tone (formal or casual), and vocabulary, from your historical sent emails. When drafting a reply, it uses this learned model to generate suggestions that mirror your authentic voice. You are always in control, with the ability to edit any draft before sending, ensuring every communication feels personal and appropriate.

Is my data private and secure with Mailopoly?

Absolutely. Security and privacy are foundational to Mailopoly's design. The company is SOC 2 certified, which is a rigorous auditing standard for data security. It employs a privacy-first approach, ensuring your email data is handled with strong encryption and robust security practices. You can review their detailed privacy policy for specific information on data handling and retention.

What happens to the emails Mailopoly filters out?

Emails deemed low-priority or "noise" by Mailopoly's Cleanbox AI are not deleted. They are intelligently filtered into a separate "Other" section within the app. You can review this section at any time, ensuring you never miss anything. The system is designed to hide distractions, not remove information, and you can easily "teach" it your preferences with one tap to refine its filtering accuracy over time.

SupaSidebar FAQ

Is SupaSidebar a browser extension?

No, SupaSidebar is not a browser extension. It is a standalone, native macOS application that installs directly on your Mac. It integrates with your system to capture links and information from all major browsers (like Safari, Chrome, Firefox, and Arc) but operates independently from the menubar. This architecture makes it more stable, universally compatible, and powerful than a simple extension.

Which browsers does SupaSidebar work with?

SupaSidebar is designed to work seamlessly with all major browsers on macOS, including Safari, Google Chrome, Mozilla Firefox, Arc, and others. Its system-level integration allows it to capture the current tab's URL and title regardless of which browser you are using, making it a truly universal tool for managing web-based resources across your entire workflow.

Where is my data stored?

Your data is stored locally and privately on your Mac. SupaSidebar operates on a privacy-first principle; all your saved links, files, folders, and organizational spaces are kept on your device. The app does not send your personal data to external servers. Optional iCloud syncing is available if you wish to sync your data across multiple Macs, but this is under your complete control.

Is there a free trial?

Yes, SupaSidebar offers a fully-featured Free Forever plan that includes support for all major browsers, 3 organizational Spaces, and the core functionality like global shortcuts and Recents. The Pro features, such as unlimited Spaces, come with a 7-day free trial that requires no credit card. You can start with the free plan and upgrade to Pro at any time.
