I make MemoryPlugin (https://www.memoryplugin.com) that adds long term memory to TypingMind. Works very similar to ChatGPT but adds some improvements on top, like "Buckets" where you could categorise and isolate related memories together, so imagine a Bucket for each Agent for instance.

Also your memories can be shared across ChatGPT, Claude and Gemini first party apps (+LibreChat too).

I would love something like this, or the ability to ask questions across chats. I do appreciate that this probably wouldn't be easy but it would be amazing.

Seems like a pretty intense feature to make. How would it know what to memorize?

Plus one. A memory variable which would be appended to default system prompt would be amazing.
