PureRef and Organizer in One App: Stop Running Two Tools (2026)

Most artists who use PureRef for reference boards also run Eagle or Allusion for their library. The reason is simple: PureRef has no search or tagging, and Eagle has no canvas. Neither was designed to do the other's job, so you need both. refern is a single desktop app that combines an Eagle-style library with a PureRef-style infinite canvas, so you stop switching between two tools entirely.

That said, the dual-app setup is functional and each tool is genuinely good at what it does. This page explains why the two-app pattern exists, what it costs you, and when collapsing into one app makes sense vs. keeping the specialist tools.

Why artists end up running two apps

The core problem is a deliberate gap on both sides.

PureRef is a board, not a library

PureRef is excellent at one thing: putting reference images on screen while you work in another app. The always-on-top overlay, transparent-to-mouse mode (click-through so you can eye-drop colors into Photoshop), and lightweight canvas are genuinely best-in-class for that use case. PureRef has been at this since 2013 and the overlay experience is polished.

But PureRef has no database, no search, and no tags. Its own handbook is explicit about this: there is no way to find a specific image once your board grows large except by scrolling. A forum thread from 2022 asked for folders, tags, and tabs; the feature has not shipped as of PureRef v2.1.3. [pureref.com/forum/read.php?3,2698] Each .pur file is a self-contained board. There is no "all references I have ever collected" view, no cross-project retrieval, and no way to find that anatomy study from six months ago without remembering which board it is on.

PureRef is a whiteboard. It is not a library.

Eagle is a library, not a canvas

Eagle is the dominant asset manager in the category for good reason. It supports 99 to 108 file format previews depending on platform, has a mature plugin ecosystem, a robust browser extension, and handles very large libraries with reported stability at 600K to 2M+ files. [en.eagle.cool/store]

But Eagle has no canvas. There is no infinite board, no overlay mode, no pin-on-top, no drawing tools, no freehand annotation. It is a library manager with no composition surface. Artists who need to arrange references spatially while modeling or painting in another app cannot do that inside Eagle. So they open PureRef alongside it.

Eagle also copies every file into its .library folder on import. This can double disk usage. Its own FAQ addresses the common question about why the library takes more space than the original files. [en.eagle.cool/blog/post/eagle4]

Allusion is a free library, also not a canvas

Allusion takes a similar role to Eagle for budget-constrained or open-source-committed artists. It indexes your images in place without copying them (similar to refern), supports hierarchical tags, and is free. Its homepage explicitly positions it as complementary to PureRef. [allusion-app.github.io]

The limitation is the same: no canvas, no color search, no visual similarity search, and no active development. The project's last official release was February 2023 and a GitHub issue filed April 2025 declared it unmaintained. [github.com/allusion-app/Allusion/issues/649] For artists who need a library, Allusion works if the library is small, but the combination with PureRef remains a two-app setup.

What the dual-app setup costs you

Running two specialist tools works. Plenty of professional artists do it every day. But it has real costs:

Your canvas and your library are disconnected. Images you pull onto a PureRef board are not indexed in your Eagle or Allusion library unless you explicitly import them. References you save via Eagle's browser extension do not automatically appear on your PureRef boards. The two systems do not talk to each other.

Context switching breaks concentration. Hunting for a reference in Eagle, then dragging it into PureRef, then realizing the image you need is in a different Eagle folder, then switching back, is cognitive overhead that adds up across a long work session.

Two file locations to manage. Eagle stores copies of your files in its .library folder. PureRef embeds images inside .pur files. Your references end up scattered in multiple locations on disk, some in Eagle's library, some living only inside a .pur board. Recovering everything after a drive failure or a .pur corruption (which can happen when a save is interrupted) requires tracking down both sources. [pureref.com/forum/read.php?5,1367]

RAM pressure compounds. PureRef loads all board images into memory uncompressed. A developer post on the PureRef forum confirmed this explicitly. [pureref.com/forum/read.php?2,1947] Running PureRef with a large board alongside Eagle with its thumbnail cache and browser extension adds up quickly on machines with 16 GB or less.

How refern combines both into one app

refern is a desktop reference manager for artists that combines Eagle-style organization with a PureRef-style infinite canvas and an Obsidian-style relationship graph. It costs $30 one time, runs on Windows, macOS, and Linux, and does not copy your files.

The library side

refern indexes your existing folder in place. You point it at a folder on disk, and it builds a SQLite index and thumbnail cache alongside your originals without moving or copying anything. This is fundamentally different from Eagle's approach. If you delete refern, your files are exactly where they were.

The library includes nested folders, hierarchical tags with tag groups and linked tags, color labels (9 colors), ratings (1 to 5 stars), source URLs, descriptions, notes, creator fields, and custom metadata. Smart folders auto-populate based on saved search queries. Directory metadata presets auto-apply tags when a file lands in a folder.

Search uses SQLite FTS5 with 14+ inline operators: type:image, tag:anatomy, rating:>=3, color:#a34b2c, is:duplicate, derived:, linked:, and more. Color search finds images by dominant color, HSV histogram, and color layout. Visual similarity finds images that look like a target image. All of this runs locally with no API calls.

A browser extension (Chrome, Firefox, and Safari) adds hover-save, right-click save, and batch save from any website, routing images directly into your library with tag-on-save. You can also import an existing Eagle library with folders, tags, ratings, sources, and notes intact.

The canvas side

The infinite canvas supports layers and groups (nestable, named, optionally backgrounded), text elements, 9 shape primitives, freehand drawing with a pen tool, image filters (brightness, contrast, saturation, hue), and non-destructive crop.

The overlay features match PureRef's core use case. The canvas window can be pinned on top of other applications, set to any transparency level, and made click-through (mouse events pass through to the app underneath). You can arrange references on the canvas and eye-drop colors directly into Photoshop, Procreate, Blender, or any other app without switching windows. That is the same workflow PureRef is known for, built into the same app that holds your library.

From the library, you drag images directly onto a canvas. From a canvas, images appear in a "Placed in canvases" section of the sidebar so you can see which canvases an image appears on. The library and the canvas are connected.

The relationship graph

refern also includes a navigable relationship graph view across your library: folders, images, canvases, groups, and the typed links between them. Typed links include grouped (fan cards in the grid), derived-from (crop provenance), placed-in-canvas, and cross-reference. The graph view works like Obsidian does for text notes, but for visual references. Neither Eagle nor PureRef has anything comparable.

Side-by-side comparison

Where each specialist tool still wins

The comparison above is not a case against PureRef or Eagle. Both are strong tools with real advantages.

PureRef wins on:

• Free for personal and student use. No other tool in this category is free with the same canvas quality.
• 13+ years of trust and industry penetration. PureRef is taught in concept art schools and used in game studios. refern is new (June 2026).
• Instant start with zero setup. Open PureRef, drag images, done. No workspace to create.
• Proven per-project workflow. The one-file-per-project .pur model fits single-assignment moodboards well.
• Larger community of tutorials and content on YouTube, ArtStation, and 80.lv.

Eagle wins on:

• Format breadth. 99 to 108 native file format previews, including fonts, audio, 3D (.glb/.stl), and rare design formats. refern previews images and video natively; creative source files are indexed but not rendered.
• Font management. Eagle can preview and categorize fonts without installing them. refern cannot.
• Plugin ecosystem. Hundreds of community plugins for format conversion, AI tools, and workflow automation. refern has none at launch.
• AI auto-tagging. Eagle's AI Action plugin (announced March 2026 for Eagle 4.0) can auto-name, auto-tag, and auto-sort on import. refern's equivalent local-model auto-tagging is planned, not shipped.
• Larger established community and support surface.

If your workflow depends on those specific Eagle or PureRef strengths, the dual-app setup or a single-specialist-tool choice may still be the right answer.

Who should consolidate into one app

The single-app approach makes sense if:

• You collect references across projects and need to find them later by name, tag, or color. PureRef has no search; an Eagle-only workflow requires opening Eagle and then exporting to PureRef. refern keeps both in one place.
• You use your canvas references beyond the session. If you want to know which images you placed on which canvases, or find all images tagged "anatomy" regardless of which board they appeared on, that cross-reference is impossible in a two-app setup.
• You are on Linux. Eagle does not have a Linux client. PureRef does, but it has no library. refern runs natively on all three platforms.
• You want your references in your own folder structure. Eagle copies files into its proprietary library. refern and PureRef both leave files in place, but PureRef embeds them in a .pur binary. refern keeps them in a normal folder you own.
• You want a relationship graph across your references. Neither Eagle nor PureRef has this. refern's graph view shows how folders, images, canvases, groups, and tagged relationships connect.
• You are paying for commercial use. PureRef requires $49 for the Small Business license (commercial use). Eagle is $34.95. refern is $30 and includes commercial use with no tier distinction. [pureref.com/download.php]

The dual-app setup remains a sensible choice if:

• You are a student or early-career artist who needs a free tool. PureRef at $0 personal + Allusion at $0 is a fully functional setup with no cost.
• You depend on Eagle's plugin ecosystem or font management.
• You are deeply practiced on PureRef's keybindings and canvas feel. The switching cost is real.
• You only need per-project boards that you discard after each assignment. PureRef's one-file-per-project model is genuinely efficient for this use case.

Getting started if you want to try one app

refern offers a 30-day free trial with full features and no account required. If you have an existing Eagle library, the Eagle import reads your folders, tags, ratings, source URLs, and notes. Your original files stay where they are. If you decide refern is not for you, deleting it leaves your folder exactly as it was. There is no lock-in.
