Webjimbo lets you access the popular information management program Yojimbo from anywhere on the Web--even from your iPhone, which Webjimbo has been optimized to handle. You work through a Web-based interface that's very similar to the Yojimbo desktop interface, letting you add new information and access anything you've previously stored--from text to images to PDFs--from anywhere you can open a browser. There are some limits, however: for example, you can only edit notes in plain text, and you can't view some encrypted data (such as PDFs or images).
Webjimbo doesn't duplicate your data and uses standard SSL encryption for live access to your Mac, which is a benefit in terms of security, but it also means that your computer has to be on and connected for Webjimbo to be effective. Unfortunately, Webjimbo costs almost as much as Yojimbo itself--but if you already use Yojimbo, it can be an extremely handy addition, even if you use it as Web-based solution only for sharing Yojimbo data between multiple users or computers (which can otherwise be difficult with the desktop app alone).
