Automatically updating ORCID, etc, from arXiv?
Google scholar will add anything it finds to your profile automatically. Usually it is more necessary to clean up (e.g. if a name of a preprint does not match the published version exactly) than to add more.
ORCID only lists papers that are published by journals - no preprints. But it also does this automatically (and does a good job - you can help if you use your ORCID during submission).
I don't know about research gate.
