@MemoryPlugin

I'm using MemoryPlugin since a year. It is brilliant how can it improve the work with LLM-s. With any LLM-s. Asad did a lot of improvement, he is open for discussion about enhancements.

Wisdolia is such an useful tool to make flashcards and review content in such an efficient and entertaining way, since you can make flashcards and type the answer and the IA will tell you in which way you got it wrong or right. It's not entirely free unfortunately, you get a limited amount of cards per month.

Great for small assignments and trying to parse through a large document. Got a subscription last month, pretty cheap which is a good benefit, totally worth the cost.
