On Sunday, I posted about changes in Wolfram|Alpha. Today, Wolfram released Wolfram|Alpha Pro.
Starting today, everyone has access to Wolfram|Alpha Pro at wolframalpha.com. Unlike the “tourist” version of Wolfram|Alpha, though, you have to log in, and, yes, to get full capabilities there’s a subscription ($4.99/month, or $2.99/month for students). (Right now, you can try it for free with a trial subscription.)
Let’s talk first about output. Once you’ve logged in, you have access to your history, and you can define favorites. You can also set preferences, like what location Wolfram|Alpha should assume, or what unit system you want to use. And you can do things like change the overall size of Wolfram|Alpha output.
By scrolling over the output, the new buttons that are available are enlarge, data download, customize and size image, copyable plaintext, and enable interactivity.
Read through the rest of the features on their blog at http://blog.wolframalpha.com/2012/02/08/announcing-wolframalpha-pro/. Which new features will be most beneficial to you?
