Message Digest

Message Digest is a personal, single-user tool. It runs on its owner's own computer, picks out firm plans from the owner's own messages, and adds them as events to a dedicated "Message Digest" calendar in the owner's Google Calendar.

It is not a public service and is not offered to anyone else. There is no sign-up and no account to create.

What it does with Google Calendar

• Creates one secondary calendar named "Message Digest" and adds, changes or removes events only on that calendar.
• Reads events on the owner's main calendar for the day of a new event, to avoid adding a duplicate.
• Moves one of the owner's own events to a new time when the owner agreed to the change in a message.
