I released a UI last week noco-ai/spellbook-docker (github.com). Has chat plugins with 50+ in v0.1.0 that handle things like simple math (multiplication, addition, ...), image generation, TTS, Bing news search, etc.

Might be overkill for your use case but the UI I created stores conversations in MariaDB, it is not multi user so anyone who accesses the UI will see the same conversations.
I am releasing a UI that meets those requirements in the next few days, was originally going to have the code ready the 31st of last month but has some stuff come up. Here is a link to the original post I made on it a few weeks back, it supports what you are looking for and has other cool features like plugins (chat function calling) and model routing.

OpenAI is also so overwhelmed with demand that their API "limits" are a complete joke. I have a tier 4 account and have always hit server error issues when running any kind of single threaded application with their API well before hitting any of their published limits. I get more TPS from my local systems than I was ever able to get from the OpenAI API.
