SELF-IMPROVING MEMORY FOR AGENTS
Summary from the TLDR AI newsletter
Perplexity Brain is a memory system that builds a persistent context graph across tasks, projects, decisions, files, and sources so agents can start with relevant context instead of starting from scratch. Brain links every memory to its original source, continuously updates and organizes knowledge over time, and improves answer correctness while reducing task costs through better retrieval and reuse of prior work.
