Feature Comparison

LuxSign

Sovereign Luxembourg Data Hosting

Every document you upload, sign, and store on LuxSign is processed and kept on secure servers located exclusively within Luxembourg. This is a foundational feature that guarantees compliance with the EU's General Data Protection Regulation (GDPR) and Luxembourg's national data protection laws. By eliminating data transfer outside this strict jurisdiction, LuxSign provides a legally watertight environment for handling sensitive contracts and personal data, making it the definitive choice for businesses with high compliance mandates in Europe.

eIDAS-Compliant Electronic Signatures

LuxSign provides Simple Electronic Signatures (SES) that are fully compliant with EU Regulation 910/2014 (eIDAS). This means every signature generated through the platform carries legal validity and is admissible in court across all European Union member states. The platform is built to support the legal requirements for most business transactions, offering a seamless bridge between digital convenience and legal enforceability without the need for complex hardware or certificates for standard agreements.

Flexible Signing Workflows & Collaboration

Move beyond simple one-to-one signing. LuxSign supports sophisticated workflows for documents requiring multiple signatories. You can choose parallel signing for faster turnaround, where all parties sign simultaneously, or sequential signing to control a specific approval order. This is enhanced by Collaboration Workspaces in advanced tiers, allowing teams to organize documents in shared folders, manage member permissions, and work together seamlessly on complex signing processes from a centralized hub.

Comprehensive Audit Trail & Security Logs

For compliance, verification, and internal oversight, LuxSign automatically generates a detailed, tamper-proof audit trail for every document. This log meticulously records every action—from sending and viewing to signing—with precise timestamps, IP addresses, and signer identification. This feature provides complete transparency over the signing process, creating an immutable record that is essential for audits, dispute resolution, and demonstrating due diligence in regulated industries.

Refbox

Always-on-Top Floating Frames

This foundational feature allows you to pin any reference—images, videos, GIFs, or notes—into individual frames that float above all other application windows. You can resize, reposition, and minimize these frames with ease, ensuring your key sources of inspiration are always visible as you sketch, design, or animate. This eliminates constant window-switching, a major workflow interruption, and keeps your focus locked on creation.

Masonry Mode & Desktop Canvas

Refbox offers a unique, organized sidebar that displays your references in a dynamic Masonry layout. From here, you can drag and drop items directly onto your desktop, creating a customizable, infinite canvas of inspiration. This mode is perfect for building mood boards, arranging storyboards, or simply keeping a collection of related visuals within easy reach and sight, all without leaving your creative environment.

Markdown-Enabled Notes & Checklists

Beyond visual media, Refbox integrates powerful note-taking directly into your reference ecosystem. Create notes with markdown support for styling, and even embed checklists for project to-dos or step-by-step instructions. This consolidates your workflow by removing the need for a separate note-taking app, keeping your creative briefs, ideas, and action items pinned right alongside your visual references.

Advanced Media Controls

Refbox provides deep control over your reference media. Scrub through videos and GIFs frame-by-frame for detailed study, perfect for animators and motion designers. Capture website screenshots by simply pasting a URL, crop images to focus on specific details, pick colors directly from any pinned media, and view SVG files as images. These professional-grade tools save hours of manual work in other applications.

Use Cases

LuxSign

HR & Employee Onboarding

Streamline the entire employee onboarding journey by sending offer letters, employment contracts, confidentiality agreements, and policy documents digitally. New hires can sign from any device, anywhere, accelerating their start date. HR teams benefit from automated reminders, organized workspaces for each hire, and a complete, secure digital audit trail that replaces cumbersome physical files and manual follow-ups, ensuring full compliance with data protection laws.

Law firms and corporate legal departments can expedite the execution of client engagement letters, settlement agreements, vendor contracts, and non-disclosure agreements (NDAs). The eIDAS compliance ensures legal validity across the EU, while features like sequential signing allow for partner approvals before a document is sent to a client. The secure, Luxembourg-hosted environment is critical for maintaining attorney-client privilege and protecting sensitive case-related information.

Freelancer & Small Business Proposals

Freelancers, consultants, and small business owners can project professionalism and close deals faster by sending project proposals, service agreements, and invoices that require a signature directly through LuxSign. The free tier is perfect for starting out, allowing them to sign their own documents and receive signed contracts from clients securely. This eliminates printing, scanning, and email ping-pong, saving valuable time and creating a more reliable client experience.

Enterprise Procurement & Vendor Management

Large organizations can manage high-volume procurement processes efficiently. Using bulk sending and template features, teams can send out thousands of standardized vendor agreements, purchase orders, or compliance certificates simultaneously. The integrated audit trail provides a centralized record for the entire procurement cycle, while API integrations allow LuxSign to connect directly with existing ERP or procurement software, creating a seamless, automated workflow.

Refbox

3D Modeling and Texturing

For 3D artists, maintaining visual consistency is crucial. Refbox allows you to pin reference images for textures, lighting, anatomy, and concept art directly over your 3D viewport. You can scrub through turntable videos frame-by-frame, pick colors from photos for materials, and keep modeling guidelines visible, all without ever leaving your modeling software, accelerating the entire sculpting and texturing process.

UI/UX Design and Development

Designers and developers can use Refbox to pin style guides, component libraries, and competitor screenshots for quick comparison. The floating frames ensure brand colors, spacing rules, and layout references are always in view while designing in Figma or coding in an IDE. Notes can hold hex codes and copy, while the gallery mode on a second monitor is perfect for reviewing full user flow mockups.

Digital Illustration and Concept Art

Illustrators and concept artists can build a dynamic mood board by dragging inspiration images directly onto their desktop canvas around their drawing software. They can lock a frame with a specific anatomical reference to draw over, use the color picker to sample palettes from photos, and keep narrative notes or client feedback pinned and visible throughout the entire sketching and painting phase.

Animation and Motion Graphics

Animators can pin sequential storyboard frames, character turnarounds, or video references in floating frames to study movement. The frame-by-frame scrubbing for GIFs and videos is indispensable for breaking down complex motions. Having these critical motion references always on top of the timeline in After Effects or Blender ensures accuracy and saves immense time otherwise spent switching back and forth.

Frequently Asked Questions

LuxSign FAQ

Is a LuxSign signature legally valid?

Yes, signatures created with LuxSign are legally valid. The platform provides Simple Electronic Signatures (SES) that comply with the EU's eIDAS regulation (910/2014). This makes them legally admissible and valid for a wide range of business and personal transactions across all European Union member states. For transactions requiring a higher level of legal presumption, such as certain government documents, you may need to consider Advanced or Qualified Electronic Signatures.

Where is my data stored with LuxSign?

All your document data is encrypted and stored exclusively on secure servers located within Luxembourg. We do not transfer or replicate your data to data centers in other countries. This sovereign hosting model is a core tenet of our service, designed to ensure strict compliance with the EU's GDPR and Luxembourg's national data protection regulations, giving you full certainty about your data's jurisdiction.

What file types does LuxSign support?

LuxSign supports all common document formats for signing, including PDF, DOC, and DOCX files. When you upload a Word document (DOC/DOCX), the platform automatically converts it to a PDF for the signing process, ensuring formatting remains consistent. There is a file size limit of 10MB per document for uploads, which covers the vast majority of standard contracts and agreements.

Can multiple people sign the same document?

Absolutely. LuxSign allows you to add up to four signers to a single document on the Premium plan. You have full control over the signing workflow: you can set it up for parallel signing, where all signers receive the document at once, or for sequential signing, where each person signs in a specific order you define. This flexibility is ideal for contracts, board approvals, or any agreement requiring multiple parties.

Refbox FAQ

What types of files can I add to Refbox?

Refbox supports a wide range of media to fuel your creativity. You can directly add images (JPG, PNG, SVG, etc.), video files, and GIFs. You can also create text notes with markdown formatting. Additionally, you can import content by dragging from the web, your local file system, or even by pasting URLs to instantly capture website screenshots.

How does Refbox help with multi-monitor setups?

Refbox excels in multi-monitor environments. You can use the full-screen Gallery mode on a secondary monitor to display an entire collection of references like a digital mood board, leaving your primary screen completely free for your creative software. Floating frames can also be moved and resized across monitors, giving you flexible control over your reference placement.

Can I organize my references into different projects?

Yes, absolutely. Refbox allows you to create multiple, distinct Collections. You might have one collection for a client's branding project, another for a personal illustration, and another for tutorial resources. You can swap between these collections instantly with a single click or a keyboard shortcut, keeping your workspace organized and context-specific.

Is there a way to quickly hide Refbox when I don't need it?

Yes, Refbox is designed to be unobtrusive. You can set your main "Box" sidebar to auto-hide, so it only appears when you need to access your library. Individual floating frames can also be minimized to a small tab or managed with keyboard shortcuts, giving you full control to clear your screen and focus solely on your primary application when necessary.
