Build a moodboard, gather references for a project, or study an artwork up close. Everything stays together instead of scattered across screenshots, folders, and tabs.
COLLECT FROM ANYWHERE • Take photos and video, scan documents, or import from Photos and Files • Save web links as preview cards, or import images, video, and PDFs from a link • Drag and drop, paste, or use the Share menu from other apps • Open common image formats along with video, GIFs, and PDFs up to 300 pages
STUDY WHAT YOU COLLECT Use the ToolBox's five lenses on any image or video frame without changing the original: • Values: grayscale, value ladder, and Notan for reading light and shadow • Color: extract a palette or inspect temperature and saturation • Composition: overlay grids, test framing, and check symmetry • Read: simplify large shapes, inspect detail density, and follow edge hierarchy • Measure: use plumb lines, snapping angle guides, and length comparisons The Analysis panel shows value range, histogram, hue, saturation, and color distribution. Export a study or keep a copy on the board. Step through GIFs and video frame by frame with onion skinning and a filmstrip.
ANNOTATE AND ARRANGE Mark up images or draw directly with pens, highlighters, and shapes. Arrange everything on an infinite canvas: drag, scale, rotate, group, nest, align, distribute, lock, undo, and redo.
YOUR BOARDS, EVERYWHERE Keep the same boards on iPhone, iPad, and Mac through iCloud. ArtDeck works fully offline and catches up when you reconnect. Choose which boards sync, use Split View or Stage Manager on iPad, and keep the ArtDeck window above other apps on Mac.
ORGANIZE IT YOUR WAY Browse every board in carousel or grid view. Add labels, combine filters, and favorite, archive, rename, or duplicate boards.
EXPORT AND HAND OFF Export a whole board or a selection as PNG, JPEG, HEIC, or PDF, up to 8K. Save a complete board as an .artdeck file for backup or handoff.
Keep what catches your eye.
Most engineering teams run AI coding agents on individual laptops. Close the lid, lose the session. When a new developer joins, they spend hours recreating the same setup.
CloudCLI gives your team shared cloud environments where AI agents run 24/7. Every developer gets their own isolated container, but the team shares MCP servers, context files, and configurations across all projects. Onboarding takes minutes.
Sessions can be started through a full REST API, so workflows in Linear, Jira, or n8n can trigger background coding agents programmatically. A ticket gets filed, an agent starts coding, the developer reviews the PR in the morning.
The web UI and mobile interface include a file explorer, git explorer, and full shell access. Review PRs on your iPad, make fixes from your phone, then pick up in VS Code over SSH.
Unlike GitHub Codespaces, CloudCLI is purpose-built for agentic development. Claude Code, Cursor CLI, Codex, and Gemini CLI come pre-installed. Sessions survive laptop closure. Teams bring their own API keys with no vendor lock-in.
Built on an open-source core (AGPL-3, 9,000+ GitHub stars). Self-host for data sovereignty or use the managed service from €7/month.
ArtDeck
CloudCLIArtDeck's answer
ArtDeck is a native Apple application, not a cross-platform wrapper. It is written in Swift with SwiftUI, and shares one codebase across iOS, iPadOS, and macOS while adapting the interface to each.
CloudCLI's answer:
CloudCLI is built with a modern JavaScript/TypeScript stack:
The entire codebase is open source under AGPL-3 and available on GitHub.
ArtDeck's answer
Against PureRef. PureRef is excellent on a desktop and has more specialized window modes: click-through transparency, always-on-top of one chosen app, separate overlays. It also runs on Windows and Linux, which ArtDeck does not. Choose ArtDeck when your references need to move between iPhone, iPad, and Mac, when you work on iPad beside a drawing app, when you study video reference, or when you want palette, value, composition, and measurement tools built in.
Against Eagle. Eagle is a library manager with strong tagging, smart folders, and batch operations on Mac and Windows. It has no native phone or tablet board. ArtDeck is a board first: things sit side by side on a canvas rather than in a grid, and the board travels with you.
Against Pinterest and the camera roll. Both are good at saving and bad at using. Pinterest ties your collection to an account, an algorithm, and a connection. ArtDeck boards are files on your devices, work offline, and never get reorganized by someone else's feed.
Against Milanote and general canvas tools. Those are built for teams planning work together, priced per seat per month. ArtDeck is built for one person studying images, bought once.
CloudCLI's answer:
Compared to tools like GitHub Codespaces, CloudCLI is purpose-built for agentic development rather than traditional coding. Here's what sets it apart:
ArtDeck's answer
Most reference apps stop once the image is saved but ArtDeck keeps going.
It is the only reference board where collecting and studying happen in the same place, on the device you happen to be holding.
CloudCLI's answer:
CloudCLI is one of the only cloud development environments built specifically for AI coding agents. Where Codespaces and Gitpod give you a cloud editor, CloudCLI gives your agents a persistent home that stays alive 24/7. What makes it particularly valuable for teams: shared MCP servers and environment configs mean every developer starts from the same baseline. A full REST API means sessions can be triggered from automation tools, not just opened manually. Background agents can run overnight and produce PRs for review in the morning. And the entire platform is open source (AGPL-3) so teams can self-host on their own infrastructure.
ArtDeck's answer
People who save images because looking at them carefully is part of how they work.
Concretely, that is digital artists and illustrators, concept and game artists, 3D artists, designers, photographers, animators working from motion reference, and art students. It also fits anyone with thousands of screenshots and saved pins who has never been able to actually use them.
What they have in common is a habit rather than a job title: they gather references from the web, the camera roll, files, and other apps, lay them out side by side, and study what makes them work. They also tend to own Apple hardware and move between it during a single project. Save something on the phone in the morning, study it on iPad beside Procreate in the afternoon, organize the board on Mac later.
CloudCLI's answer:
CloudCLI is built for engineering teams that use AI coding agents as part of their daily workflow. This includes teams adopting agentic development practices with tools like Claude Code, Cursor CLI, or Codex who need shared environments where MCP servers, context files, and configurations stay consistent across every developer. It also serves engineering managers looking to integrate AI agents into existing workflows through API-driven automation with tools like Linear, Jira, and n8n. Solo developers and open-source contributors who want persistent remote access from any device are also a core audience, along with organizations that need to self-host for data sovereignty or regulatory compliance.
ArtDeck's answer
ArtDeck started from a personal problem: references were everywhere and useful nowhere. Saved pins in one place, screenshots in the camera roll, links in browser tabs, images in folders. Plenty of collecting, almost no returning.
The first version was the fix for that, a board where images, links, notes, and videos could sit together on one canvas and come along across iPhone, iPad, and Mac.
The second idea is the one that shaped the app. Collecting a reference and understanding it are not the same thing. Artists have always had a manual set of moves for the second part: squint at the image, flatten it to values, sample the colors, check where the lines land, measure the angle. Those moves were happening outside the app, in other tools or not at all. So ToolBox was built into the board, five lenses that open on any saved image without taking you away from it.
The belief underneath all of it is that what you collect shapes what you create. Collecting is creative work, not filing. And a tool for that should be yours: one purchase, no subscription, works offline, your boards on your own devices.
CloudCLI's answer:
CloudCLI started as an open-source project to solve a problem every developer using AI coding agents hits: your agent ties up your terminal and stops working when your laptop sleeps. We built a cloud-native environment where agents run persistently, paired with an open-source web UI so anyone could manage sessions from a browser or phone. As teams started adopting it, the focus shifted to shared environments, where team-wide MCP servers, configurations, and context files could be maintained in one place instead of duplicated across every developer's machine. The project grew to 9,000+ GitHub stars organically with no marketing. Today CloudCLI offers both a free self-hosted option and a managed cloud service starting at €7/month.
