Feature Comparison
LuxSign
Sovereign Luxembourg Data Hosting
LuxSign's foundational and most critical feature is its exclusive data residency within Luxembourg. Unlike platforms that use global or US-based cloud servers, LuxSign ensures all document processing, encryption, and storage occurs on secure servers physically located in Luxembourg. This guarantees compliance with GDPR and the strict Luxembourg data protection legal framework, providing unparalleled peace of mind for businesses handling sensitive European personal and corporate data. Your documents never leave the protective jurisdiction of the EU.
eIDAS-Compliant Legal Validity
LuxSign is built to comply with the EU's eIDAS regulation (910/2014), providing Simple Electronic Signatures (SES) that are legally admissible and valid for a vast majority of business transactions across all 27 EU member states. This feature removes the legal ambiguity often associated with digital signatures, offering a secure and court-admissible audit trail. For transactions requiring higher assurance, the platform is structured to support Advanced and Qualified Electronic Signatures, making it a versatile legal tool.
Intelligent Drag-and-Drop Workflow Builder
Streamline complex signing processes with an intuitive visual editor. Users can effortlessly drag and drop signature, initial, date, and text fields onto any PDF or Office document. This feature allows for the configuration of parallel signing (all signers at once) or sequential signing (in a specific order), enabling the automation of multi-party agreements, HR onboarding, or client contracts with just a few clicks, dramatically reducing processing time from days to minutes.
Comprehensive Collaboration Workspaces
Move beyond single document transactions with dedicated team workspaces. This advanced feature allows teams to organize documents into folders, manage member access permissions, and collaborate seamlessly on ongoing signing projects. It centralizes control, enhances visibility into team activity, and simplifies the management of high-volume signing operations, making it ideal for legal, sales, and HR departments that handle numerous contracts simultaneously.
Refbox
Always-on-Top Floating Frames
This is the cornerstone of the Refbox experience. You can pin any reference—image, GIF, video, or note—into a dedicated frame that stays visible above all other applications, whether you're in Photoshop, Blender, Figma, or your code editor. These frames are fully resizable and can be minimized or locked, ensuring your inspiration is always just a glance away without obstructing your work. It completely eliminates the disruptive cycle of window switching, keeping you locked in your creative zone.
Intelligent Media Sidebar & Collections
Acting as your central command hub, the Refbox sidebar lets you effortlessly gather media from anywhere: drag-and-drop from your computer, paste directly from your clipboard, or import from the web. You can then organize these assets into multiple, separate Collections for different projects or themes. Switching between a character design board and a UI kit reference is as simple as a single click, keeping your workspace meticulously organized and your resources instantly accessible.
Masonry Mode & Infinite Canvas
For visual thinkers, how references are displayed is crucial. Refbox’s Masonry Mode automatically arranges your images and media in a dynamic, Pinterest-style grid on an infinite canvas, allowing you to see your entire inspiration board at once. Alternatively, you can flip through items in a focused slideshow view for detailed comparison. This flexible viewing system adapts to your task, whether you're building a broad mood board or examining specific details.
Advanced Creative Utilities
Refbox goes beyond simple pinning with a suite of powerful, niche tools that cater to professional workflows. Step through GIFs frame-by-frame for precise animation reference, use the built-in color picker on any media to capture hex codes, create website screenshots by pasting a URL, and even crop images on the fly. For pixel artists, the Pixel Rendering mode ensures crisp, non-blurry viewing, while SVG support and styled notes with checklists round out a feature set designed to handle the real-world complexities of creative work.
Use Cases
LuxSign
Enterprise Contract Management & Procurement
Large organizations can leverage LuxSign's bulk signing, custom branding, and full API access to integrate e-signatures directly into their ERP or procurement systems. The platform automates the sending of vendor contracts, NDAs, and purchase agreements, with all documents and audit trails securely stored in Luxembourg for compliance. The collaboration workspaces allow legal and procurement teams to manage workflows efficiently.
Legal & Financial Services Compliance
Law firms, consultancies, and financial institutions handling highly sensitive client data require guaranteed GDPR and local law compliance. LuxSign's sovereign data hosting and eIDAS validity make it the perfect tool for signing client engagement letters, confidentiality agreements, and financial reports. The tamper-proof audit trail provides a verifiable record for regulatory inspections and dispute resolution.
HR & Remote Employee Onboarding
Modern HR departments can onboard employees anywhere in the world swiftly and securely. Using sequential workflows, new hires can digitally sign employment contracts, policy acknowledgments, and tax forms in a predefined order. Automated email notifications and reminders ensure the process stays on track, while all personal data remains protected under EU law within LuxSign's secure platform.
SME Sales & Client Agreement Acceleration
Small and medium-sized businesses can close deals faster by sending proposals, service agreements, and sales contracts directly from LuxSign. The simple three-step process (upload, place fields, send) allows sales teams to operate with professional efficiency. The Premium plan's features like templates and cloud integrations (e.g., connecting to Google Drive or Dropbox) make repeating this process for multiple clients incredibly efficient.
Refbox
3D Modeling and Texturing
For 3D artists working in software like Blender or Maya, maintaining visual consistency is key. Refbox allows you to float reference images of concept art, material samples, and orthographic views directly over your viewport. You can color-pick directly from textures, step through animation GIFs for movement study, and keep model sheets visible without ever leaving the modeling environment, dramatically speeding up the sculpting and texturing pipeline.
UI/UX and Web Design
Designers in Figma or Adobe XD can use Refbox to keep competitor screenshots, design system components, and brand guideline documents pinned and accessible. The ability to take instant website screenshots by pasting a link is invaluable for research. By organizing different client projects or page types into separate Collections, designers can maintain a clutter-free workspace and iterate faster with all necessary references persistently on screen.
Digital Illustration and Concept Art
Illustrators and concept artists can build dynamic mood boards by pulling in inspiration from across the web into a single Refbox collection. Using Masonry Mode, they can view an entire palette of inspiration at once. While painting in Photoshop or Clip Studio Paint, they can float specific anatomical references, color palettes (captured with the color picker), and style frames right beside their canvas, enabling a truly immersive and reference-rich painting session.
Motion Graphics and Animation
Animators and motion designers can leverage Refbox to pin video reference clips, storyboard frames, and timing charts in always-on-top windows over their timeline in After Effects or Premiere. The GIF playback control is particularly crucial for analyzing motion frame-by-frame. This setup allows for precise side-by-side comparison of reference and work-in-progress, ensuring accurate timing and movement without constant playback toggling and window management.
