form_remote_tag is used for creating a form which will be submitted via Ajax.

There is actually four types of form commands, in two categories:

Model-Backed Forms (forms based on a activerecord object)

Regular Forms (forms not based on a particular object)

and then there are the Ajax and POST variety of each.

So we have:

1) remote_form_for (ajax, model-backed) which is used to perform ajax
actions on a form which is composed of fields relating to a specific
active record object.

2) form_for (standard POST, model-backed) which is for performing a
standard http post on a form which is composed of fields relating to a
specific active record object.

3) form_tag (standard POST, not model-backed) which is for performing a
standard http post on a form which is not model backed and has arbitrary
input fields.

4) form_remote_tag (ajax post, not model-backed) which is for performing
a ajax post on a form which is not model backed and has arbitrary input
fields.
