We have a user developed tool here
http://www.geni.com/projects/SmartCopy/18783
Technical requirements:
- data subscription from MyHeritage (I believe this is available monthly), which I believe requires a Geni PRO subscription 1st (annual)
- Chrome browser (it's an add on extension)
It's a copy utility. Basically a macro that parses a web page and copies those fields into a Geni profile. So it works with the collections where the parsing has been worked out. That includes the free FindAGrave site.
One use of SmartCopy could be uploading a GED file to MyHeritage and then "copy it across" to Geni.
