IWantSandy.com and responds via email, in natural language to my requests that she remember people, (web) places, and events.
So I emailed Sandy, Remember Election Day is November 4 and this morning she sent me the reminder pictured in this post.
I've asked Sandy to remember birthdays, appointments, group meetings, and household maintenance items I need to perform on a periodic basis. She works admirably at all.
Her real power is in acting as a reminder to a group of an event they have agreed upon. She is so efficient at the task that I've had correspondents ask me if I could have my assistant assemble and edit their slides for them.
I did a radio segment about Sandy at some point in the past. I'm going to have her put it on my ToDo list to go find it and post it here (if I haven't already.)

As you can see above, she will even tag things for you.
