This was mentioned on the Digitalclassicist list and it’s kind of neat (especially if you’re metrically challenged, as am I). You can cut and paste Greek text into it and it will break it down (seems to work best if you apply correption and synizesis):

I wish this featured more visual integration. The analyses are placed to the side of each line, so it feels like the writing’s being translated into some kind of code. If only they could place the meter notation directly above the line, like musical notes, we’d have something golden.
Thank you for your comment, Ryan. We just launched an update with the notation above the line, as you requested.
