In Toast of the Town, we discussed how to promote your products and improve customer experience with screencasts. Now the makers of ScreenToaster have come out with Screenjelly, a pared down version of the original offering. With Screenjelly, you can quickly and easily record up to 3 minutes of video and audio from a simple, one-click interface. Screenjelly is a browser-based application, so no need to download or install anything. One button – that’s it.

The real selling feature of this service is the viral capabilities. Screenjelly comes with a built-in Twitter feature. Once you’re finished recording your screencast, you can quickly tweet it to your entire Twitter network. If you’re maintaining a company Twitter account, imagine promoting mini videos for product updates (e.g. like we did here when we integrated DocStoc with Lizzer) or walking customers through a sign-up process for a contest or event.

Screenjelly is free, so you don’t need to sign up or pay a fee. Just login with your Twitter account to tweet your video. And if you’re not into the Twitter hype, you can share your video via email or different social sites like Facebook, Digg, Delicious, etc. Like Twitter, these options are available directly from the recording interface.
