Spongecell: An Online Calendar

Spongecell is an innovative online calenar with lots of features. You can enter new appointments into the Spongebar as if you were naturally speaking. For example, "Soccer practice every other Wednesday at 6," and the appointments are created. You can click and drag to create an appointment, drag and drop to move it, and drag its borders to resize it. You can receive reminders on your cell phone, invite them to new events, and publish public and private calendars via RSS and iCalendar.

The Spongecell developer API is built with Ruby on Rails, and the javascript libraries Prototype and script.aculo.us. The patent-pending natural language processing (NLP) engine that powers the Spongebar and email/TXT entry is written in Java. As they progress, additional inputs to the NLP engine will be exposed.

The mobile features are what make Spongecell really stand out. You can use Spongecell with any mobile phone via text messaging. Some examples of the mobile features (from the Spongecell website):

1 - Send a txt message with a new appointment to sponge@spongecell.com - for example, “Dinner with bob next thursday”. Time isn’t mandatory, the sponge will do it’s best to figure out what you mean.
2 - Subscribe to your calendar via RSS feed. There are many different time frames to choose from. Hint - feeds in “weeks” are Sunday through Saturday, and feeds in “days” are Today + X days.
3 - To find out the details of your next appointment, send a txt message that says “next” to sponge@spongecell.com. This also works for “today”, “tomorrow”, “next thursday” and a date such as “june 23″ to get a list of appointments.
4 - Set a reminder to be sent to your mobile phone. Just click the “Text Message” box in the event details.
