The fact that it does not require my clients to create login details or download apps. You can also click the preview button to see the file and the annotation features exactly as the clients will see it.

Good, helping to reduce time working on creatives with clients as amends and tasks can be seen in a visual way with an audit trail

I've been using it for a few months to manage graphical revisions of my products, and I have to say it's solved a problem I've had for years: the classic infernal circle of emails with attachments, randomly renamed versions, and clients commenting on blurry screenshots via WhatsApp. The thing I appreciate most is the version comparison system—there are four different modes, and the "Difference" mode in particular is something I didn't know I needed so much. You upload the old and new versions, and the software highlights exactly what's changed. It seems trivial until you realize how much time you were wasting checking every corner by eye. The fact that external reviewers can access it via a link without registering is also a huge convenience: clients don't want to create yet another account, so they open the link, leave comments directly on the file with the annotations, and that's it. In short, it's one of those tools that makes your life easier.
