GatherOS keeps your library local on your Mac rather than in the cloud, arranges items on an open canvas instead of a grid, and syncs saves from X and Instagram automatically. It launched into public beta in April 2026 and is still active, with a Chrome extension and a small but real user base. What it does not have yet is a shipped 1.0 or an announced price, which is the main reason people go looking for something they can commit to right now.
The right alternative depends on whether you most want the freeform canvas, the local-first ownership, or both. Below is a quick side-by-side, then a short, honest profile of each option. We make one of them, Muse, and for people who want a native Mac app they can buy and use today, with a freeform Canvas view built in, we think it is the best fit, with its trade-offs called out as plainly as everyone else's.

The alternatives, one by one
Honest profilesMuse Our pick for Mac
$29 once · 30-day trialBest for: People who want GatherOS's local-first, native-Mac idea in a shipped app they can buy and rely on today.
Muse is a native Apple Silicon app that keeps your library as real files on your Mac, with no account and no cloud, matching GatherOS's local-first approach. It has a freeform Canvas view for arranging items spatially, alongside Cards, List and Timeline, so you are not locked into one layout. Its AI runs entirely on-device: it tags items, reads the text inside images, and does colour and visual search. It also imports your X bookmarks directly. Where it is honestly weaker than GatherOS's stated ambitions: Muse's X import is a one-off pull rather than continuous live sync, and it does not sync Instagram saves at all, in line with Instagram's own guidelines.
Strengths
- Shipped and stable, not a beta with no price
- Local files you own, no account or cloud
- A real freeform Canvas view, not just grids
- On-device AI, including search inside images
- One $29 payment, imports your X bookmarks
Trade-offs
- X import is a one-off pull, not live sync
- No Instagram sync
- Mac only, with no phone or web app
Milanote
Free (capped); Individual $9.99/moBest for: Planning and moodboarding on a visual board, with a real free tier to try it first.
Milanote is a well-established visual board tool for planning projects and moodboards, with notes, images, links and to-do lists arranged freely on a canvas. It runs on the web plus Mac, Windows and mobile apps, and is cloud-based so your boards sync everywhere. The free plan is capped at 100 items and 10 uploads, after which Individual is $9.99 a month. It leans toward planning and presentation more than a searchable personal library.
Strengths
- Mature, polished canvas for planning and moodboards
- Real free tier, works on every platform
- Great for presenting boards to others
Trade-offs
- Free tier capped at 100 items
- Cloud-based, ongoing subscription for real use
- Less of a searchable personal library
Kosmik
7-day trial; Pro from about $12/moBest for: People who want an infinite canvas with AI moodboarding and a built-in browser and PDF reader.
Kosmik is an infinite-canvas app for images, notes, files, PDFs and web pages, with AI features aimed at moodboarding and an in-canvas browser so you can research without leaving the board. It runs on Mac and Windows and is cloud-based. It offers a 7-day trial before a Pro subscription, cited at roughly $12 a month by most sources, though it is worth a final check on their own site before you commit.
Strengths
- Genuine infinite canvas with AI moodboarding
- Built-in browser and PDF reader in the canvas
- Handles a wide range of file types
Trade-offs
- Cloud-based, not local
- Subscription only, short trial
- Pricing needs a final check on their site
Apple Freeform
FreeBest for: Quick moodboards and whiteboards using an app you already have, at no cost.
Freeform is Apple's own infinite-canvas whiteboard, built into every Mac, iPad and iPhone. You can drop in images, video, PDFs, sticky notes and drawings anywhere on the board, and it syncs through your iCloud account for free. It is a whiteboard rather than a searchable, tagged library, so it suits quick moodboarding and brainstorming more than long-term organising of a large collection.
Strengths
- Completely free, already on your devices
- Syncs through your own iCloud
- Good for quick moodboards and brainstorms
Trade-offs
- No tags, search or real library structure
- Not built for a large, long-term collection
- Apple only
Eagle
$34.95 onceBest for: People who want a mature, deep local library and do not mind folders and grids instead of a canvas.
Eagle is a well-established local library for images, video, audio, fonts and design files, organised into folders and smart folders rather than a freeform canvas. It supports over 90 formats and runs on Mac and Windows for a one-time $34.95. If GatherOS's spatial canvas was the main draw, Eagle will feel different, but if what you actually wanted was a stable, mature, local library, it is one of the safest choices available. See the full Eagle alternatives roundup for more.
Strengths
- Mature, deep local library, one-time price
- Supports 90+ file formats, Mac and Windows
- Long track record, actively maintained
Trade-offs
- No freeform canvas, folders and grids only
- Built with Electron, not native
- Links are second-class next to visual files
