ArtDeck VS DynamicDocumentAPI

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.

DynamicDocumentAPI's answer:

It covers the whole path from data to finished document in one API: you design a template in a visual or HTML editor (or send raw HTML, CSS or Markdown), send JSON, and get a PDF or image back. The same service also creates e-invoices (XRechnung, EN 16931, Factur-X / ZUGFeRD) that are validated against the official rules before they are returned, and can embed them in the PDF. Rendering is deterministic: the same template and data always give the same document, laid out by a headless browser, with no AI model generating content. Everything runs in the EU (Germany). It also ships an MCP server, so AI agents like Claude and ChatGPT can render documents directly.

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.

DynamicDocumentAPI's answer:

Most document APIs do one thing: convert HTML to PDF, or fill templates. Dynamic Document API does both, adds image templates, PDF merging and validated e-invoices, and offers them through a REST API, SDKs for Node and Python, Zapier, Make, n8n and an MCP server for AI agents. Data is processed and stored in the EU only, files come back as signed links that expire, and storing nothing at all is a supported option. Pricing is predictable: one published credit table, the same core features on every paid plan and a spend cap you control. We also publish a render-time benchmark with its method and raw data, so you can check our speed instead of trusting a claim. The free plan includes 50 renders a month without a credit card.

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.

DynamicDocumentAPI's answer:

Developers and product teams whose software has to send documents: invoices after a payment, certificates after a course, reports, labels and statements. Typical users are SaaS companies, marketplaces, e-commerce and learning platforms. A second group are businesses in Germany and the EU that need compliant e-invoices (XRechnung, ZUGFeRD) for the German B2B e-invoicing mandate and public-sector buyers. No-code builders use it through Zapier, Make and n8n, and teams building AI agents use the MCP server.

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.

DynamicDocumentAPI's answer:

Almost every product eventually needs to produce documents, and most teams end up building their own rendering stack: a headless browser, fonts, page breaks, storage and retries. It works until an invoice splits a table row or a certificate shows the wrong date, and then it becomes a support ticket. We built Dynamic Document API to be that layer for them: templates, rendering and delivery as one service, hosted in Europe, treating pagination, fonts and formatting as engineering problems rather than edge cases. When e-invoicing became mandatory for B2B in Germany, we added validated XRechnung and ZUGFeRD output, and with AI agents producing more paperwork, an MCP server followed.

ArtDeck'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.

DynamicDocumentAPI's answer:

Rendering runs in Rust workers that drive headless Chromium over the DevTools protocol, with MiniJinja for templates. The API and control plane are built with Django and Django REST Framework, with Celery, PostgreSQL, Valkey and NATS JetStream for queues and events, and S3-compatible object storage for files. PDF/A output is checked with veraPDF and e-invoices with the official KoSIT validator. The dashboard and website are built with Next.js. Everything runs on Kubernetes in data centres in Germany.

DynamicDocumentAPI's answer:

Dynamic Document API is a young product. Our users are mostly developers and small SaaS teams, and we don't name customers without their permission.
