I've created a plugin for Typing Mind that enables long term memory. You won't have to set up any servers for this.

The plugin is able to store and retrieve memories, and the great thing is that it's using a vector database instead of text search, a vector database knows that if you mention "rose", it's a plant, a flower, a name, a type of scent, etc.

You can check out the plugin here: https://www.memoryplugin.com :)

I think it can be set up as a custom model since you can run it as a server, in which case TypingMind won't care how the MemGPT internals work or won't need any integration. I added a FR for adding documentation about it: https://typingmind.canny.io/feature-requests/p/add-documentation-for-setting-up-memgpt
