The tool is simple, easy-to use for users without any technical knowledge or expertise in design software (such as Photoshop). It's also free! I have no complaints about this product at all so far - it has been very helpful with our branding needs since we are not designers ourselves. We're using coreBook mainly because of its ease-of-use but it does offer some great editing tools too which other products lack such as guides that can be applied across multiple pages/images easily plus text frames where you can add custom fonts etc., really useful if your website contains images from different sources like stock photos / logos & icons + vector graphics created by yourself via Adobe Illustrator CC 2018+.
