refern is a local-first desktop app for collecting, organizing, and working with visual references.

The library side gives you folders, hierarchical tags, smart folders, ratings, color labels, color search by hex, image-to-image visual similarity, and more than 14 typed search operators, all running on your machine with no account and no cloud.

The canvas side is a full infinite moodboard with layers, text, shapes, freehand drawing, image filters, and a pin-on-top mode with adjustable transparency and click-through, so it covers the always-on-top reference workflow too.

A relationship graph view maps how your folders, images, canvases, and tags connect. refern never copies your files: a workspace is a normal folder on disk, and it indexes your originals in place.

Questions & Answers

As answered by people managing Convertio and refern..

What's the story behind your product?

refern.'s answer:

I'm an artist, and too often I was frustrated: I couldn't find the right pictures, I struggled to organize and keep track of my reference images, and I was juggling too many apps when all I wanted to do was draw. I wanted one tool that could do it all, with every component well integrated. So I made refern.

What makes your product unique?

refern.'s answer:

The flow of collecting references for art usually goes like this:

find references and inspiration online -> save and organize those images -> use them on their own or in a moodboard -> reuse them for the next project or share them with others

Normally that means a different app for each step. refern does all of it in one place, with every part built to work together.

Why should a person choose your product over its competitors?

refern.'s answer:

Most tools solve only one part of the reference workflow, so artists end up juggling several. refern combines them in one app: Eagle-style organization and search, a PureRef-style infinite canvas, and an Obsidian-style graph of how your references connect. It never copies your files, so it doesn't double your disk usage. It runs on Windows, macOS, and Linux, works fully offline, and is a $30 one-time purchase with no subscription. Built in Rust, it stays fast even on libraries with hundreds of thousands of images.

How would you describe the primary audience of your product?

refern.'s answer:

Individual artists and creative professionals: illustrators, concept artists, digital painters, designers, and photographers. They collect and organize large libraries of visual references, build moodboards, and study from reference. refern is built for solo creators rather than teams, spanning hobbyists and students through working professionals.

Which are the primary technologies used for building your product?

refern.'s answer:

refern is a Tauri v2 desktop app with a Rust backend and a React 19 (with React Compiler) plus TypeScript frontend. Data is stored locally in SQLite (rusqlite) with FTS5 full-text search. The interface uses Tailwind CSS, Zustand, and TanStack Query, with motion/react for animation. The infinite canvas and graph view are built on react-three-fiber and three.js. Thumbnailing, perceptual hashing, and color and visual similarity run in Rust with rayon and SIMD.

Best Online Image Converters in 2026: Docpose.cloud Leads the Pack
Users highlight Docpose.cloudโ€™s reliabilityโ€”no failed conversions even on rare formats. CloudConvert gets praise for quality tweaks but frustrates with daily resets. iLoveIMG is loved for extras like AI, but free limits irk. Smallpdf suits PDF-image hybrids, less pure images.
