Obsidian for Images vs refern: 2026 Comparison

TL;DR: Obsidian is excellent for local Markdown knowledge management and can support image workflows through attachments, plugins, and note conventions. It does not ship a first-party visual DAM. refern is built for visual references, with a native image grid, color and similarity search, canvas, and a relationship graph designed around visual assets.

Quick verdict

Introduction: two local-first tools, two different jobs

Both Obsidian and refern are local-first desktop apps that put you in control of your files. Both have a graph view. Both let you arrange things on an infinite canvas. Both avoid storing your data on someone else's server by default.

That is where the similarity ends.

Obsidian is built for thinkers who work in text. Its graph connects notes, wikilinks connect ideas, and its plugin ecosystem extends that text foundation in nearly unlimited directions. Artists and designers who reach for Obsidian to organize visual references are trying to use a text-first architecture for a job it was not designed to do.

refern is built for visual references. The primary view is a masonry image grid. Every search feature, every metadata field, and the relationship graph itself are designed around images, not text documents.

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 $35 one time, runs on Windows, macOS, and Linux, and indexes existing folders in place.

What is Obsidian?

Obsidian is a local-first markdown note-taking and personal knowledge management app made by Dynalist Inc., first released in 2020. It stores notes as plain markdown files in a user-owned folder called a vault, connects them with wikilinks and bidirectional backlinks, and visualizes those connections as an interactive graph. Its 2,700+ community plugins and 548+ themes make it one of the most extensible productivity apps available. [Source: obsidian.md, moritzjung.dev plugin stats]

The core app is free with no account and no telemetry. Cross-device sync is a paid add-on at $4 per month billed annually, or $5 per month billed monthly, as of 2026 (obsidian.md/pricing). Obsidian runs on Windows, macOS, Linux, iOS, and Android.

It is genuinely excellent at what it does. The "second brain" and Zettelkasten communities have made Obsidian a standard for good reason: plain files, no lock-in, a mature plugin ecosystem, and a model of sustainable indie software that is an inspiration for refern's own approach.

What is refern?

refern is a desktop visual reference manager for artists and designers, built on Rust via Tauri v2 and available on Windows, macOS, and Linux. During normal workspace indexing it leaves existing images in place and builds a local index and thumbnail cache; explicit imports and capture actions can create files and application metadata remains after uninstall until removed.

The app has four main pillars: a masonry image library with folders, hierarchical tags, smart folders, 21 user-visible search operators, color search, and visual similarity; an infinite canvas with layers, shapes, text, drawing, filters, crop, and overlay mode; a relationship graph; and browser extensions for Chrome, Firefox, and Safari.

refern costs $35 one-time. One license covers up to 3 devices, commercial use included. There is a 30-day free trial with no account required.

Organization and search

Obsidian

Obsidian's organization is folder-based and tag-based, with nested tags and the file explorer. For text notes, this is powerful and natural. For images, the architecture creates friction.

Images in Obsidian are vault attachments. Obsidian does not ship a first-party visual DAM with per-image ratings, color search, or similarity search, so structured gallery workflows typically use plugins or one-note-per-image conventions. A Medium author documented limitations in one such 900-image setup; treat that as one workflow report, not a universal Obsidian ceiling. [Source: medium.com images-as-notes article]

A 2021 thread on the official Obsidian forum titled "Creating an image gallery" found no built-in solution. The thread remains unsolved. [Source: forum.obsidian.md image gallery thread]

refern

refern's interface is built around image organization. Every folder is a masonry gallery. Tags support hierarchies, groups, links, and macros. SQLite FTS5 search exposes 21 user-visible operators such as type:image, tag:architecture, rating:>=4, color:#3a5f8a, is:duplicate, derived:, and linked:. Color and visual-similarity search run locally without a search API.

Smart folders let you save any search query as a live folder that updates automatically as your library changes.

Verdict: refern provides a purpose-built image-library model, while Obsidian relies on notes, embeds, and plugins. If organizing, tagging, and searching visual references is your goal, compare the workflows with a representative vault or library; no controlled cross-product scale benchmark is published.

Canvas and boards

Obsidian

Obsidian added Canvas in December 2022 as an infinite whiteboard for arranging notes, images, PDFs, and web content. Cards can be edited inline. Connections between cards can be labeled and colored. It exports to image and uses an open JSON Canvas format.

For brainstorming text ideas in a spatial layout, Obsidian Canvas works well. For visual reference boards, it shows strain. Artists in the Obsidian forum have requested features that have not been addressed: grayscale toggle, nearest-neighbor rendering for pixel art, proper image scaling by resolution, and mass import from disk. A 2023 forum thread on these requests was closed by a moderator without resolution. [Source: forum.obsidian.md canvas-for-artists thread] There is no search within a canvas board, no per-image metadata sidebar, and no always-on-top overlay mode for use alongside other applications.

refern

refern's canvas is designed around images. You can import images from your library or from disk, arrange them in layers with fractional z-ordering, group them with named and colored group backgrounds, and crop non-destructively. Text blocks, 9 shape types, freehand drawing with the perfect-freehand stroke model, and color swatch elements round out the canvas. Image filters let you adjust how references look on the board without modifying the original file.

The nearest-neighbor rendering that Obsidian artists asked for and did not get is a per-file setting in refern. Flag a file as Pixelated and it draws with hard pixel edges instead of blurring at every size, in the grid, in the viewer, and on the canvas. Flag a whole selection at once from the metadata sidebar, then pull the set back up with the is:pixelated search operator. Sprite sheets and game art stay legible when you scale them up on a board.

The pin-on-top mode is the PureRef use case, built directly into refern: you can pin the refern window on top of any other application, adjust transparency, and enable mouse clickthrough so clicks pass through to the app underneath. This lets you use refern as a floating reference overlay over Blender, Photoshop, or any other tool.

Verdict: For ideas and notes arranged spatially, Obsidian Canvas is capable. For visual reference boards with image-specific controls, refern's canvas is purpose-built. Artists who currently use PureRef for the overlay use case will find that use case covered directly in refern.

Relationships and graph view

Obsidian

Obsidian's graph view is the most mature knowledge graph implementation in personal software. It shows the connections between all your notes based on wikilinks and backlinks, with filtering by depth, tag groups, and color coding. For visualizing how your ideas, research, and writing connect across a text-based knowledge base, it is excellent.

The graph does not understand images as distinct objects. An image embedded in a note appears as a property of that note, not as its own node. You cannot navigate from an image to related images via the graph, or see that two folders both contain reference images of the same subject.

refern

refern's relationship graph is built for visual assets. Every image, folder, canvas, and group is a node. Typed entity links create edges: member-of (group membership), derived-from (crop provenance), placed-in-canvas (canvas references), and cross-reference (manual direct links). The Linked References sidebar shows, for any selected image, everything that references it, everything it has been cropped from, every canvas it appears in, and everything directly linked to it.

The mental model will feel familiar to Obsidian users: bidirectional backlinks, a navigable graph, and typed relationships between entities. The difference is that the entities are images, canvases, and folders rather than text notes.

One refern alpha user described it as "what if Obsidian had pictures instead of notes." That framing captures what the relationship graph is doing here: the same philosophy applied to a visual library.

Verdict: Obsidian's graph is a major strength for text knowledge. refern applies a related navigation model to visual-library entities. This comparison does not claim that no other visual graph product exists.

Pricing

Obsidian wins on upfront cost: the core app is free, full stop. If you only need one device and no sync, Obsidian costs nothing.

The calculus changes when cross-device access matters. Obsidian Sync Standard is $4 per month billed annually or $5 monthly; Plus is $8 annually or $10 monthly as of September 1, 2026. refern licenses up to three devices but does not yet sync the library between them. Obsidian has a shipped encrypted sync solution now.

Full feature comparison

Who should choose refern

refern is the right choice if your primary need is managing, searching, and using a library of visual references.

Choose refern if you:

• Work as an artist, illustrator, concept artist, game developer, or designer and keep a library of reference images.
• Want to search your images by tag, color, rating, source, or visual similarity without setting up plugins or building workarounds.
• Use PureRef as a reference overlay and want that functionality combined with your image library.
• Currently run Obsidian + Eagle + PureRef as three separate tools and want to consolidate the visual-reference half of that stack.
• Care about a graph view that shows how your visual references relate to each other, not just how your text notes connect.
• Want to own your images without any app copying or locking them.

refern is not the right tool if you need text-heavy knowledge management, a second brain for research and writing, a mobile app, or a cross-device sync solution today.

Who should choose Obsidian

Obsidian is the right choice for text-based personal knowledge management, and it has no serious competition in that domain.

Stay on (or switch to) Obsidian if you:

• Think in text and want a "second brain" for research, writing, ideas, and notes.
• Need a plugin ecosystem to extend your tool in every direction imaginable.
• Want iOS and Android apps with sync built in.
• Need collaborative shared vaults.
• Value the free-core-app pricing model.
• Are a developer, researcher, or writer whose primary assets are documents, not images.

Obsidian is also worth keeping alongside refern. The "Obsidian for text, refern for visuals" combination is exactly what several refern alpha users described as their preferred setup.

Switching from Obsidian to refern (or adding refern)

Most users will add refern rather than replace Obsidian, since the tools handle different things. But if you have been using Obsidian Canvas or an "images as notes" plugin stack to manage visual references, here is what to expect when you move that work to refern.

What transfers easily:

Your image files are just files in a folder. Point refern at the folder where your images live (inside or outside your Obsidian vault), and refern will index them in place without moving or copying anything. Your originals stay where they are, untouched.

If you have been storing metadata in markdown frontmatter, you will need to re-enter tags and ratings in refern. refern does read EXIF, IPTC, and XMP metadata embedded in image files on import, so if your images carry embedded metadata, refern will pick it up automatically.

If you are coming from Eagle, refern's importer has full parity across its supported transfer surface. It copies the first media placement, uses linked database placements thereafter, and excludes password locks, saved smart-folder rules, arbitrary plugin-owned data, and unsupported media.

What does not transfer:

Text notes that live in separate markdown files do not have an equivalent in refern. refern supports descriptions and notes on images, but it is not a markdown editor. Keep Obsidian for that.

Wikilinks between notes have no equivalent in refern's relationship model. refern's typed entity links connect images and folders to each other, not notes to images.

Zero lock-in:

Normal refern workspace indexing leaves files in place. If you stop using refern, the SQLite index and thumbnail cache inside the workspace can be deleted without affecting your originals. Explicit import, copy, and move actions can create or relocate files only when you choose them.

The verdict

Obsidian and refern are complementary tools that happen to share a local-first philosophy and a graph view. They are not competing for the same job.

If you are using Obsidian to manage visual references and feel like you are fighting the tool, that friction is real. Obsidian's architecture was not designed for images. The workarounds are documented, community-maintained, and brittle at scale.

refern is the local-first visual reference manager that Obsidian users have been describing when they ask "what if Obsidian had pictures instead of notes." It applies the same philosophy (local files, no lock-in, relationship graph, search as a first-class feature) to a library of images rather than a library of text.
