Scapple — a cross between scabs and Snapple? Thankfully not: Scapple is in fact a brand new (as in beta) mind-map app for writers. What’s that, you say? There are already a ton of mind-map apps out there? That’s true. But none of them comes from the developer of the awesome Scrivener.

Next Monday is November 1st and for us would-be wordsmiths, that date has special import as the first day of National Novel Writing Month, or NaNoWriMo. Over the next thirty days, tens of thousands of would-be novelists will smash out as much prose as they can, trying to finish the first draft of a short, complete novel before the clock strikes midnight on November 30th.

In order to help novelists prepare for the orgy of fiction that will all but consume the lives of Mac-using NaNoWriMo next month, Scrivener — our favorite project planner for writers and novelists — has seen fit to release the public preview of the much anticipated 2.0 update… and it’ll be completely free to use until December 7th.
