Feature Comparison
Refbox
Always-on-Top Floating Frames
The core feature of Refbox is its floating frames. You can pin any image, video, GIF, or note in a resizable window that stays on top of all other applications, like Photoshop, Blender, or your code editor. This eliminates the need for alt-tabbing or rearranging windows, keeping your reference material instantly accessible and your primary workspace uncluttered. You can have multiple frames open at once, each independently adjustable.
Masonry Mode & Gallery View
Refbox offers flexible viewing options to suit any task. Masonry Mode automatically arranges your references on an infinite canvas in a clean, Pinterest-style grid, perfect for mood boarding and seeing the big picture. For focused review, the full-screen Gallery View lets you flip through items like a slideshow, making detailed comparison quick and effortless.
Smart Media Handling & Tools
Beyond simple display, Refbox includes powerful tools for working with your references. You can step through GIFs frame-by-frame for detailed study, take screenshots of websites by pasting a URL, and use a built-in color picker on any media to copy hex codes. It also supports cropping images, viewing SVG files, and creating styled notes with checklists, making it a versatile hub for all your reference needs.
Streamlined Workflow Shortcuts
Designed for efficiency, Refbox is packed with intuitive controls. Quickly swap references in a frame using your arrow keys, minimize frames to access apps behind them, or instantly switch between different collections of references. You can auto-hide your entire "Box" and summon it only when needed, keeping your screen clean until inspiration strikes. These thoughtful shortcuts save countless clicks and hours over time.
SureThing.io
Proactive Autonomous Operation
Unlike passive tools that wait for commands, SureThing takes initiative. It constantly scans your connected work environments—like your email inbox—identifies what needs attention, and acts on your behalf. This means it can flag urgent messages, draft initial responses, and manage routine tasks without you having to prompt it every single time, freeing you to concentrate on strategic thinking.
Persistent, Adaptive Memory
This is SureThing's core superpower. It builds a comprehensive understanding of you over time, remembering your communication style, your priorities for different projects, and your preferences for scheduling. The longer you work together, the less context you need to provide. It won't forget a detail you mentioned last week, ensuring consistency and personalized service in every action it takes.
Enterprise-Grade Security & Reliability
SureThing is built for users who need to trust an AI with real, sensitive work. With SOC 2 certification and Google CASA Tier 2 compliance, it meets rigorous standards for data security, privacy, and system availability. This foundation of trust means you can confidently connect it to your critical work apps, knowing it's designed for dependable, day-in, day-out performance.
Cross-App Action & Integration
SureThing doesn't just observe—it acts. It can move information and execute tasks across the applications you use, such as updating your project management tool when an email confirms a deliverable or scheduling a follow-up meeting based on a conversation thread. This creates a seamless, automated workflow that bridges gaps between your favorite tools.
Use Cases
Refbox
Digital Illustration & Concept Art
Illustrators and concept artists can keep character sheets, environment photos, and color palettes floating right next to their canvas in Clip Studio Paint or Procreate. The ability to lock frames means they can even sketch directly over a reference without it moving, and the pixel-perfect rendering mode ensures pixel art references are displayed with crisp clarity.
UI/UX & Web Design
Designers building interfaces in Figma or Sketch can float style guides, competitor screenshots, and component libraries in Refbox. The website screenshot feature lets them quickly capture live pages for reference, and the color picker tool allows instant sampling and copying of colors directly from any inspiration image into their design tool.
3D Modeling & Animation
3D artists and animators working in Blender or Maya can pin orthographic reference images, texture photos, or motion study videos in floating windows around their viewport. The GIF playback control is invaluable for animators to scrub through frame-by-frame to study movement, all without leaving their 3D workspace.
Motion Graphics & Video Editing
Motion designers in After Effects or video editors in Premiere Pro can use Refbox to keep storyboards, style frames, and video reference clips visible. They can organize sequences in the Gallery view to flip through quickly, ensuring their creative direction stays consistent throughout the editing and compositing process.
SureThing.io
The Overwhelmed Solo Founder
For a founder running a business alone, SureThing acts as a force multiplier.

SureThing can prioritize emails, draft succinct summaries of long threads, schedule meetings based on preferences, and ensure nothing falls through the cracks, allowing the executive to stay focused on leadership and decision-making.
The Project Manager Juggling Multiple Threads
SureThing helps project managers stay on top of dependencies and communications. It can monitor project-specific email channels, update task statuses in tools like Asana or Jira based on updates, send gentle reminder follow-ups to contributors, and compile progress reports, keeping the entire project moving forward smoothly.
The Professional Protecting Deep Work Time
For anyone who needs uninterrupted blocks of time, SureThing serves as a protective shield. It can handle routine communications, filter out non-urgent notifications, and only escalate truly important items. This allows the user to enter a state of deep focus without the constant fear of missing something critical.

Frequently Asked Questions
Refbox FAQ
What kinds of files can I use with Refbox?
Refbox supports a wide range of media types to cover most creative needs. You can directly add common image formats (JPG, PNG, WebP, SVG), video files (MP4, MOV), and GIFs. You can also create and format text notes right within the app. A standout feature is the ability to paste a website URL, and Refbox will automatically generate a screenshot of that page for you to use as a reference.
Does Refbox work on multiple monitors?
Yes, absolutely. Refbox is designed for modern workflows and works seamlessly across multiple monitors. You can drag your floating reference frames onto any screen, allowing you to dedicate one monitor entirely to your references in Masonry mode while keeping your main screen focused on your creative application.
Can I organize my references into different projects?
Yes, you can. Refbox allows you to create and save multiple Collections. This lets you separate references for different projects, clients, or tasks—like one collection for a logo design and another for a website redesign. You can switch between these collections instantly with a single click, keeping your workspace organized and context-specific.
Is there a free trial or version of Refbox?
Refbox operates on a simple, one-time purchase model. This means you pay once and own the current version of the app forever. While there isn't a traditional subscription, the website may offer a limited-time trial so you can test all the features and ensure it fits your workflow before making the one-time purchase.
SureThing.io FAQ
How is SureThing different from a standard AI chatbot?
Standard chatbots are reactive—they only respond when you ask a question. SureThing is proactive and autonomous. It takes initiative based on its understanding of your work and goals. Furthermore, its persistent memory means it learns and remembers your context permanently, unlike chatbots that start fresh with each conversation.
What does "Google CASA Tier 2 Compliant" mean?
Google's Cloud Application Security Assessment (CASA) framework evaluates the security of applications that integrate with Google Workspace. Tier 2 compliance is a rigorous level that indicates SureThing has undergone a thorough independent security review, giving you confidence that it handles your Google-connected data with a high standard of protection.
Can I control what SureThing does on my behalf?
Absolutely. You maintain full oversight. SureThing is designed to suggest actions and draft communications for your review before sending. You can approve, edit, or reject anything. Over time, as it learns your preferences, it may automate more routine tasks, but you always have the final say and can adjust its permissions.
How does SureThing learn my "voice" for communication?
SureThing analyzes your past written communications—emails, messages, etc.—to understand your tone, formality, common phrases, and style. When it drafts a reply or message, it mimics these patterns. You can also provide direct feedback ("make this more casual" or "sound more enthusiastic"), which it remembers and applies to future drafts.
