What decides this category
Citation quality, and it is the one thing a vendor rarely publishes a number for. Every answer engine cites. The difference shows up when you open the link and check whether the page supports the sentence it was attached to.
Because no vendor publishes a figure for that, we do not print one either. What we can publish is what each tool says its free tier allows and where that is written down.
Why this is not filed under AI Chatbot
An assistant is bought to produce something. An answer engine is bought to find something and show its working. The overlap in technology is not an overlap in what a buyer is choosing between.
What we publish here
Profiles only, for now.
