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.

Proofsnap features and specs

  • Photo Documentation with Timestamps
    ProofSnap allows users to capture and store timestamped photos, providing verifiable proof of conditions, progress, or events at specific points in time, which is valuable for contractors, inspectors, and property managers.
  • Easy-to-Use Interface
    The app is designed with simplicity in mind, making it straightforward for users to quickly snap photos and organize documentation without a steep learning curve.
  • Organized Project Management
    ProofSnap helps users organize photos by project or job, making it easy to keep track of documentation across multiple assignments and retrieve evidence when needed.
  • Proof for Dispute Resolution
    The timestamped and geotagged photo evidence can serve as useful documentation in disputes with clients, insurance claims, or legal situations, helping professionals protect themselves.
  • Cloud Storage and Backup
    Photos and documentation are stored in the cloud, reducing the risk of losing important evidence due to device failure or accidental deletion, and allowing access from multiple devices.

Possible disadvantages of Proofsnap

  • Niche Use Case
    ProofSnap serves a relatively specific market of professionals who need photo documentation proof, which means it may not offer enough general-purpose features to justify the cost for casual users.
  • Subscription Cost
    Like many SaaS tools, ProofSnap may require ongoing subscription fees that can add up over time, which could be a concern for independent contractors or small businesses on tight budgets.
  • Dependence on Internet Connectivity
    Cloud-based features may require reliable internet access to sync and upload photos, which can be problematic for users working in remote job sites or areas with poor connectivity.
  • Limited Brand Recognition
    As a smaller or newer tool in the market, ProofSnap may lack the extensive user community, third-party integrations, and established trust that larger project management or documentation platforms offer.
  • Potential Storage Limitations
    Depending on the pricing plan, there may be limits on the number of photos or amount of storage available, which could be restrictive for users who handle large volumes of documentation across many projects.

Questions & Answers

As answered by people managing refern. and Proofsnap.

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.
