All the above exist now, have existed for years, and with the recent rise of AI require less effort to use than ever. But not an app but rather are website search engines and news aggregator sites like Google, Bing, and Yahoo. The primary issue in the past is that many people, especially seniors that have not used computers until recently, have not adequately learned how to use computers and specifically Internet programs.
In decades past, there were many news stories of people who were never able to program their TV VCRs to record programs, or use even simple early era GUI interfaces of newer products like FM radios. With the rise of smartphones, all this has just become more divisive between the tech savvy and those not.
Usually, the issue is more one of attitude, not being willing to read the user information and manual. Although some of those are language limited, or sbubstance use dumbed, there are plenty of otherwise intelligent persons that are simply too lazy to bother reading instructions, a poor habit developed by many in recent decade public schools. Many people just want to turn power on any device and perform simplest operations, without having to deal with setting up options or going into specific modes or entering commands. Because their past experience is one of getting confused and lost trying to deal with such minor complexities, they learn to avoid and ask others for help. Not a wise direction in an increasingly complex and competitive world unless one isolates themselves in rural environments.
I spent much of a career working with the most complex equipment and programs, and was very good at it, that resulted in better paying employment in electronic hardware engineering. I also occasionally wore customer and field support service hats and the most common issue has always been a lack of RTFM. So instead of just answering questions say on the phone or within email, I would first point to user manual pages and website product information as a way of showing the many people, that resist doing so, that they really didn't need to contact support for most issues.
