Brush library and installer for digital artists

The moment someone decides to go beyond the defaults — whether for realistic sketching, graphic design, or illustration — they fall into a hole. They search Reddit threads and DeviantArt posts, download ZIP files from random shareware sites, manually move files into obscure application folders, and still aren't sure if the brush will even work with their specific software version. This is a genuinely recurring frustration that touches nearly every serious user of any major image editor.

The gap persists for a structural reason: Adobe and the other incumbents sell editing capability, not brush management. Expanding and improving the default brush set competes with the ecosystem of third-party brush creators who drive platform stickiness — so there's no incentive to make outside brush import easy or to build a curated repository. The brush creator community has grown entirely on its own, hosted on Gumroad, Patreon, and fan sites, with no standardization around compatibility metadata.

What's actually missing is compatibility-aware discovery: when a user searches for a 'watercolor texture brush', they should immediately know which results work with Photoshop 2024 vs. Affinity Photo 2 vs. Lightroom, without downloading and testing. Users specifically complained about 'brushes that are compatible with my version' being hard to confirm, and 'having to manually move them over from what I have saved them as.' Neither the editing apps nor current brush marketplaces surface version compatibility in any structured way.

This is a business because the frustration recurs every time an artist starts a new project style, upgrades their software version, or gets a new machine and has to rebuild their setup from scratch. The cost is time — often hours — plus the creative momentum lost when tooling gets in the way of making work.

What to build

Build a web-based brush marketplace where every listing carries structured compatibility tags (software name + version range), a one-click installer that handles file placement automatically for the detected local app version, and a personal library that syncs across machines so artists never manually move brush files again.

Where to start

Launch with a free personal brush library sync tool first — solve the 'I reinstalled and lost everything' pain point with zero friction — then introduce the marketplace once users have their collection organized there and have reason to discover more.

The hard part

Getting accurate, maintained compatibility metadata at scale requires either deep cooperation with brush creators (who have no current incentive to tag their work precisely) or building an automated detection layer — neither is trivial, and stale compatibility tags destroy trust faster than no tags at all.

How it makes money

Free to store and sync up to a set number of brushes; subscription (~$5-8/month) for unlimited library size, cross-device sync, and access to curated premium brush packs. Brush creators take a revenue share on paid pack sales.
