Corel Corporation is a Canadian software company that's been quietly plugging away since the 1980s, making tools for designers, photographers, and people who just need an alternative to Adobe or Microsoft. Their product line is fairly sprawling: CorelDRAW for vector design, PaintShop Pro for photo editing, Painter for digital painting, WordPerfect for word processing, and various smaller utilities. They're not a one-trick pony, which is partly their strength and partly why their website feels a bit overwhelming.
The company tends to appeal to people who either can't justify Creative Cloud subscriptions or actively dislike Adobe's direction. PaintShop Pro in particular has a loyal following among photographers and hobbyists who think Photoshop is overkill. Corel also owns AfterShot Pro, a raw image processor that's solid if not exactly mainstream. Their stuff works on both Windows and Mac, though the feeling you get is that they prioritize Windows slightly.
Prices are generally reasonable compared to Adobe, and they do one-time purchases rather than forcing you into subscriptions, which some people prefer. The trade-off is that updates aren't automatic and the community is smaller. If you're after niche design software or a genuine alternative to the Adobe monopoly, Corel's worth a look. Just don't expect the same polish across every product.
