AESio provides that encryption and security to enable online collaboration on even sensitive data projects. Once users have signed-up, they can begin uploading files and creating notes. Files can be uploaded directly if they are less than 50 MB. Users can create multiple workspaces that are sized at 200 MB each. Users can, if they wish, add collaborators to their workspace in which case the shared workspace capacity is 100 MB. Messages can be sent to one another as long as they are less than 5 MB. Notes created or shared with others, support advanced special formatting such as hyperlinks, text colors, and text highlighting in various colours.
