NavCIS, originally known as CompuServe Navigator (1992) was used to automate connections to the CompuServe Information Service and available for both MS-DOS and Microsoft Windows as a graphical interface.  Also notable as one of the first e-mail and forum clients to feature WYSIWYG e-mail in the early 1990s.

Windows CompuServe Information Manager (CIM) (1990) provided a GUI front end and was available for MS-DOS, Microsoft Windows ("WinCIM"), Macintosh ("MacCIM"), and OS/2 ("OS/2-CIM") and allowed access to CompuServe's features, such as its forums, chat, e-mail, and messaging facilities; these continued to be accessible via standard communications software using alphanumeric shortcuts. The first versions were released in around 1990. Version 2.0.1, released in 1994, included a version of the Mosaic web browser.

OzWin was a third-party client GUI program which was used to connect to the CompuServe Information Service that ran on the Microsoft Windows operating system. OzWin was born out of the earlier OzCIS program which was DOS based

Other client software included ForCIS and TapCIS.

Dick,

      WinCIM also contained and "undocumented featured" called AutoPilot ... it was an early attepmt to have the the software automatically connect and retrieve/send both email and Forum Messages in the manner of an offline reader.  Worked well.

Dick,

      >I thought that's what all offline readers did. Hmmm, come to think of it, I think I used an offline reader to go online, get forum messages, and get off.<

I don't understand what you are saying.  I am making the distinction between an offline reader that is operated 'manually', viz. the user clicks on the appropriate connect button, clicks on the various Forums one belongs to and clicks again to download any new messages ... similarly for email.

An 'automated' client is set up to do all of those things without any further user input after the initial connection click.
