Dev spends 3 days reverse-engineering Instinct's memory system, recreates it in 60 lines

DhravyaShah, founder of supermemory, published what he calls his most in-depth blogpost: a full reverse-engineering of the memory system behind Instinct, an iMessage AI assistant he considers among the best available.
After 3 days of digging, he found the design beautifully simple and highly effective. The article breaks down exactly how Instinct's memory works and shows how to implement the same approach in supermemory in about 60 lines of code.
