Web Review: https://andisearch.com
Using this site, I went to its setting on the upper right and selected in-depth answers.
An exciting mix of AI Chatbot/Search Engine with a forgiving search and interesting results.
The goodness of such a site depends on what you want to know, how to ask, and if it has been trained in a way to answer your question.
The site points to freely available resources.
Features and Functionality
I suggest looking at their About Page because the site is growing.
Benefits and Potential Use Cases
I liked each result's built-in summary and read buttons, so it might be suitable for older folks.
Drawbacks and Limitations
I liked using it the way I set it up.
Conclusion and Recommendations
Not only bookmark it but try sending it to older folks.
