Perkoon
Peer-to-Peer (P2P) File Transfer
The P2P file transfer feature allows users to send files directly between browsers without any intermediary servers. This means that there are no size limits, no accounts needed, and the process is entirely free. It leverages a decentralized network that ensures privacy, as data transmitted never touches Perkoon’s servers.
Encrypted Cloud Storage
For users needing to send files to recipients who are offline, Perkoon offers a secure cloud storage solution. This feature encrypts files while they are held on the servers, ensuring that only the intended recipient can access them. The paid service for cloud storage is transparent, as it solely covers the operational costs associated with maintaining the servers.
AI Integration
Perkoon stands out with its native design for AI interaction, allowing AI agents to communicate directly with the service without needing to scrape the interface. This innovative feature makes it easier for machines to utilize Perkoon for automated file transfers, enhancing productivity for users who leverage AI in their workflows.
Referral Program
Perkoon incentivizes its users through a referral program that rewards both the referrer and the new user with additional storage benefits. By sharing a unique link, users can invite friends to join, and once the new user engages with the platform, both parties receive bonuses, fostering a community-driven approach to file sharing.
Refbox
Always-on-Top Floating Frames
Refbox's signature feature is its ability to create persistent, floating windows for any reference media. These frames can be resized, repositioned, and set to stay on top of all other applications, ensuring your inspiration never gets buried. You can work directly behind locked frames or minimize them temporarily, giving you complete control over your screen real estate while keeping references just a click away, eliminating the need to alt-tab or dig through folders.
Infinite Canvas & Instant Collections
Organize your references on a limitless digital canvas where you can spatially arrange images, videos, and notes for any project. The app allows you to create and switch between different Collections instantly with a single click, enabling you to segregate references for multiple clients, projects, or artistic phases effortlessly. This visual organization system makes moodboarding and project planning both efficient and intuitively satisfying.
Advanced Media Handling & Tools
Refbox goes beyond simple image display with a suite of powerful, creative-centric tools. It features frame-by-frame GIF playback, pixel-perfect rendering for pixel art, and the ability to take website screenshots directly by pasting a link. You can crop images, view SVG files, use a built-in color picker on any media to copy hex codes, and save or copy assets directly to your clipboard for use in other applications.
Streamlined Navigation & Shortcuts
Designed for speed, Refbox offers extensive keyboard shortcuts and navigation aids to keep your hands on the keyboard and your mind in the flow. You can swiftly swap through references in a frame using arrow keys, auto-hide your entire Refbox panel until you need it, and execute all major functions via customizable hotkeys. These thoughtful interactions minimize friction and save valuable time during intensive creative sessions.
