I only use Gemini on PC thus far but it definitely remembers conversations. It shows an abbreviated title list on LHS so you can easily spot & enter that conversation again & carry on. Recently it introduced a different looking 'chat box' area, forgot the name. Apparently its something like incognito mode where it purges after some time amount & supposedly does not use those questions for learning. And of course I trusted it completely when I asked 'where would be a great spot to bury my 24kg of gold bars?'. I should use ChatGPT more just to toggle back & forth. I had a good session going on some engineering topic, it was charting graphs, then it suddenly ran out of gas & left me high & dry.
