If you're open to spending a little:
Help and Manual (I've used for several years)
HelpNDoc Looks Cool Also (Free Personal Edition with WaterMarks. Inexpensive for standard edition)
I have also used Confluence. $10 one time payment for self hosted 10 user
I recently started working with Dockuwiki as well for an internal site I'm creating
Dokuwiki has Bootstrap themes and all the site page files are stored as text files so you can programmatically update your site or edit the markdown files quickly.

subject: Re: [PCTECH] Documentation Software
Even though OP specifically expressed doubts about a wiki, that seems to be a popular choice.
To get an idea of the free ones out there, check out this list on Wikipedia:
Notably, all 6 of the primary implementation languages featured on that list are available for PASE, so there are plenty of choices that could run on the i if desired.
One of the ones on the list is DokuWiki, which specifically positions itself as a documentation system.
Please understand I have no personal experience with any wiki software, other than making a few edits on a handful of wiki sites, including Wikipedia.
