What's great
I have a paid subscription to Gemini, but sometimes I want/need the high end (not free) features of one or more of the other platforms and I can't justify paying for subscriptions to all of them. For example this month I needed to use the HIGH END of the Claude ecosystem, but not only is that not available in the free tier, but it's also only available in the tier that's $100/month. I used up all my 1 Min AI Credits and had to add another $10 to get everything done, but it was a FAR SUPERIOR OPTION to spending $100 and I REALLY BENEFITTED from their high end model that's not available on the $20/month option.
Also, earlier in the month I had a question that I suspected I might get Hallucinations from Gemini on, here in the Multi Ai Chat I can pose the question to 3-15 different models all at one and directly compare the answers. When they all give the same information I can be quite confident it's accurate, when they all give different answers I know I'm dealing with hallucinations and I go back to old school methods.
What needs improvement
The interface is a little clunky and it took me a little time to get used to it.
It is improving and I assume it'll continue to improve, but I was able to learn it and I'm used to it now.
vs Alternatives
Getting the all in one allows me to do more for less money. It allows me to get short term use out of a platform that I am not subscribed to and it allows me to use ALL of them without paying for all of them.
