Ancestry.com can give you automatic record hints (e.g. suggesting a birth certificate for one of your ancestors) without you doing nearly anything.

To get their automatic record hints, you just need to sign up for ancestry.com and enter as much of your family tree as you know. After that, ancestry.com will start looking for historical records using the data you provided, and will send you an email mentioning them, and keep a list of these hints in ancestry.com.

What’s more, from my experience so far their hints have been very good.

Although ancestry.com is a paid subscription, but for some reason LDS church members can access it for free (currently, anyway).
