If you're looking for a mobile app to share images with interactive comments and feedback, PinMy is a top contender. It lets you annotate images collaboratively with a range of communication tools like annotating specific parts of an image and annotating comments to specific parts of an image. The app also lets you record voice-to-text comments and share images by email, SMS or services like Slack. That makes it a good choice for designers, photographers, teachers and real estate agents, and its free plan lets you have unlimited pins and comments, while a premium plan offers more storage space and longer voice comment times.
Another good option is Commented, a collaboration and commenting tool designed to let people work more collaboratively. It's got rich annotation, task assignment, public commenting and AI suggestions. It's geared for teams, but it can be used with mobile SDKs, too, so you can use it on your phone. That could be useful for product managers, developers and designers who want to get project feedback without a lot of hassle.
For developers, Velt offers a JavaScript SDK that lets you add collaborative abilities to your products. It can handle a variety of collaboration modes, including real-time feedback, and includes features like commenting, in-app notifications and drawing tools. The SDK can be used with a variety of tech stacks and web frameworks, so it should be adaptable to whatever tools you're using for video editors, form builders, task managers and other apps.
Although primarily an image browser in the cloud, Poly has features that could be useful for sharing and organizing images. It uses multimodal AI for natural language search and customizable views. It's not designed for interactive comments, but its fast previews and organization abilities could help you share and manage your images.
