While we can’t specifically answer this question for you, maybe the following summary gives you some ideas:
- Standard: A very capable tool for everyday personal use. Multiple databases, database and in-document searching, even automation is included.
- Pro: Stepping up from the Standard edition, the Pro edition has features more commonly needed in business and academia. Custom metadata, full text concordance, scanning with OCR, and email importing are some of the high-powered functions you’ll find.
- Server: With all the power of the Pro edition, Server has a built-in webserver made for sharing databases on a network with users on other platforms or Mac users not running DEVONthink. This edition is geared toward multi-user business and group collaboration situations.
You can find a list what differentiates Pro and Server from the Standard edition on the product page.
