What makes Iterasi unique is that, unlike other bookmarking tools that just save a link, Iterasi captures a web page at a particular moment in time. This makes Iterasi ideal for saving pages that change over time or pages that disappear after you navigate away (like a receipt for an online purchase).

1) In today's release, Mac users can start to use Iterasi by installing the provided Firefox plugin. The plugin supports both Firefox 2 and 3 and works on OS 10.5 and up.

2) However, all Iterasi users will be excited about the new scheduler service. Like the name implies, the scheduler allows you to have Iterasi notarize a page on whatever scheduled basis you configure - either daily, weekly, or monthly. There are so many different ways to use the scheduler. The Iterasi team suggest you could use to capture retail sites with daily specials, for example. You could also use it in an investigative way to track a site that you think might be changing its messaging over time. You could even use it to track the changes on a site that doesn't offer a news feed for you to subscribe to. We're sure you can think of million ways to use the scheduler - those are just a few to get you started.

3) Another new feature launched today are "public pages." Each Iterasi user has a Public Webpage created for them called "My Public Pages" in the Iterasi viewer. As you save pages, you can mark them as private to keep them from being added to the Public Page. Anything else is saved to the Public Page where you can share it with friends who can then subscribe to it via an RSS reader or by using the provided widget.

4) One last feature made available just for Twitter users is the introduction of a short URL service. Using the domain http://sqrl.it (short for Squirrel It - since you "squirrel" away web pages with Iterasi), you can now tweet links to your Iterasi pages.

You can check out the new service in action in the video below:

The Web is Dynamic

Dynamic pages are those that may change at any time from its initial download. This could be from either the server's knowledge of a user or the actions of a user on the website. With many of today's pages created using dynamic technologies like CSS, AJAX, and other database-driven content, valuable information you may have wanted to save can be lost forever. Another problem that Iterasi addresses is the condition of "linkrot." This occurs when a page you've bookmarked disappears from the internet forever. With Iterasi's bookmarking service, you'll never have to lose information again.

The Iterasi application itself is a web browser toolbar. When you find a page you want to save, you click the "Notarize" button and the page is immediately transferred to a secure personal account, where a copy of the web page is saved including all images, forms, transactions, receipts, confirmations, and personalized content. Since Iterasi saves an exact replica of any web page you're looking at, it's great for things like saving online receipts or quickly capturing the contents of a page deep in search or after answering a series of questions.

Your private Iterasi account is accessible from any web browser. Within your account, you can view your saved pages, organize them into folder, add descriptions, or tag them. You can also search your saved pages using a powerful search agent that even searches the pages' text. Another great tool Iterasi provides for power users is the Scheduler, which will automate page captures on a regular basis so you can track and analyze changing web pages over time.

The Iterasi team said they've decided to start with IE7, so, at first, their toolbar with be IE-only. However, Firefox and Mac support will come later on. They based their decision on the fact that IE7 is the most widely adopted browser and the hardest to tackle, too.

When Can I Use It?

"As the Web increasingly becomes a more personal experience, there is a growing need for tools like Iterasi," said Chris Shipley, executive producer, DEMO.  "By uniting saving, searching and retrieving for dynamic and static Web content, Iterasi will be one of the more useful buttons on the ever more crowded toolbar".
