CROSS-POST FROM THE TIPS & TRICKS FORUM:
Hi Everyone,
Christian’s Evernote script in the tips forum inspired me to write a couple of my own DEVONthink=>Evernote / Evernote => DEVONthink AppleScripts. 
You can find them here:
http://veritrope.com/tips/connecting-evernote-and-devonthink-with-applescript
My approach differs in that:
[]You can select the notes to export from the script itself (don’t have to manually export the ENEX files beforehand).[/]
[*]It creates and imports a "Web Archive" from the Evernote data, preserving the formatting and content a little better.[/*]
[*]I have also added Growl Support to monitor the status of the export.[/*]
These are “the 1.0 versions” (have some ideas for the next revisions already!), so please test them out and leave me comments on each script’s page to let me know how they are working out for you!
Hope they are of help to you!
Kind Regards,
Justin
