“Good product, good customer support. I purchased PictureEcho in order to help with collating and editing thousands of digital images collected over 15+ years - it was very useful and I am really glad I came across it (I asked ChatGPT to recommend tools to help in collecting 'similar' images and PictureEcho was one of the tools it suggested) - the ability to choose the level similarity was very useful - and it is remarkable fast compared to other tools which offer to sort based on similarity. I had a glitch with the license code but the support team reacted speedily and sorted it out. Recommended product and company.”
