The AlchemyAPI Android SDK enables real-time semantic analysis of text, HTML, or Internet-hosted Web page content. The SDK provides mechanisms to extract Concepts, Named Entities, Keywords and Tags, Categories, and clean HTML into text, and even detects languages. It can analyze text in eight different languages: English, French, German, Italian, Portuguese, Russian, Spanish, and Swedish. Example code and a demo application are included to help get you started.
Google Calendar Chrome Extension adds a button to your browser toolbar that displays a preview of your calendar while you're navigating. (works on any page). If you're on certain sites where it detects the presence of events, the icon changes to a green "+". Clicking that icon lets you add the event to your Google Calendar, and shows you a Map (if there's a location it could detect.) Supported sites include Facebook, Evite, and any site that uses the hCalendar microformat or derivative microformats such as hResume.
CreditCardNanny is a Web browser extension for Google Chrome and Mozilla Firefox that detects forms that otherwise look secure (with a proper and valid SSL certificate, encrypted, and seemingly safe to enter sensitive data such as credit card details) but actually then submit this form data in a cleartext email to the site administrators. This extension detects such forms and warns you of the possibility that sensitive information may be exposed in clear-text, putting you and your sensitive data at risk. You can test the extension by browsing to https://cc-nanny.appspot.com/test-secure-page, a dummy credit card form that uses a form emailer script, a very common pattern used on an alarmingly large number of Web sites.
