One thing I’d wish for would be for it to use an LLM other than grok though.
When you connected, it would load the AOL application which contained most of what AOL offered - built in AIM (AOL instant messaging), a web browser, group chats, keyword search, email, etc.
You were still connected to the internet and could use alternate browsers, but most people stayed inside the AOL app and ecosystem. Keywords were a time before search, where companies could buy keywords (from AOL) and then when people searched them they would show up. It was kinda a separate system from DNS that AOL tried to profit from.
You had competitors like Prodigy and CompuServe offering similar dial-up + custom app offers.
You wouldn't use the AOL app without having AOL dial-up service (although I recall them offering it separately late in its life, bring your own internet). People thought "AOL" was the internet. You might recall the classic "You've got mail" movie. That was from the AOL app which loaded after connecting.
aside: It's crazy how AOL could have become Facebook. AIM chat was the main focus - but AIM had "profiles" which you could customize, and I did - even with daily status updates. Modern Facebook is basically the reverse - profiles with a chat attached.
Like Prodigy and Compuserve and GEnie and some others, it was an on-line information system. Chat, message boards, news, stock quotes, (limited) shopping, games, software downloads, etc. But all within a single system. Kind of like a nationwide/global BBS, but with a GUI interface. In the 80s, all these systems were independent, in the early 90s they got internet email, and the mid 90s added web browsers and (eventually) real tcp/ip.
All that said, I still communicate with one person who maintains their aol.com email address to this day in spite of it all.
Didn't they try to come back as a brand when free ad-supported dialups became a thing for a bit?
Related, while doing a quick search to see if I could learn anything about what you described I found Wikipedia quoting NYT as writing about EarthLink in 2000: "second largest Internet service provider after America Online". I guess it was around y2k when aol finally got its ISP (and this its "world's largest") designation by the world at large. :)
AOL allowed their users to interact with eachother (chats, forums, multiplayer games), read news, and otherwise kill some time. It was a walled garden that required both money and special software to access.
There were other paid services that were vaguely similar, each with different shapes for how the walls of their respective gardens were arranged. In the US, some of these competing services were CompuServe, Prodigy, GEnie, and Delphi.
Of all of these, AOL became the most-broadly known. As time moved on, they increasingly would mail out floppy disks with their software on what seemed like a continuous basis, with flashy color brochures, to millions of homes. (Some weeks I'd wind up with as many as 3 or 4 new AOL disks to use for whatever, delivered right to the mailbox on the front porch. Later, they'd send CD-ROMs instead that were most-useful as drink coasters.)
These services each vied to get as many users locked into their garden as possible, which was important to them because they tended to be metered services: Unlike something like a Netflix or Hulu streaming account, the more time a person spent using these services, the more money they had to spend.
And then, September came again -- and it never ended[1]. The walls of the gardens began to open up and users of these proprietary services began being exposed to what the greater Internet had to offer.
But at the same time, AOL grew. They got proper-fucking big. They went from being a cheeky dialup service with a friendly interface and some pervasive advertising campaigns to buying Time Warner for $182 billion.
And today, all of that business is just kind of a dusty memory.
When you logged in, you'd get a "Welcome" screen with news, if you had any mail, etc. Most of AOL was organized into "Channels" which were different sections focused on things like Sports or Kids.
You could jump to a channel with a keyword, somewhat like a URL.
The channels looked somewhat like hypercard decks. Everything was designed to load fast on a slow modem and assets were shipped with the client, typically on floppy or CD. Occasionally a channel would download an "art pack" which could take 5-10 minutes, but this was rare.
After AOL 2.6 or so it had internet functionality and became an ISP. You still needed to use the AOL software to dial in (it didn't use PPP like others) but otherwise it worked fine.
It was the easiest "one of those" at the time, competing with CompuServe and Prodigy. Apple had a rebranded AOL briefly called eWorld.
If you called into a certain department at AOL, you could tell them you were a business and would like to put out their CDs for display. So long as the order was for under 1000 or so they would send them to you, for free, directly to the address of the "business".
I also learned in middle school that CDs sting but don't really hurt and the various ways to launch attacks in a CD war with friends and classmates. You throw CDs vertical to be precise and sideways for a crazy flight path to confuse your opponents.
Sadly I also discovered that all the racist didn't die in the 70s, as the owner of one of the largest AOL hacking discussion forums I frequented loved to talk about how he would move if a black family ever moved into his neighborhood.
