Introducing Brain in Computer. Brain is a continuously learning memory system. Every task on Computer plugs into a context graph built by Brain. It makes Computer more stateful with every run. Available as a research preview for all Perplexity Max subscribers.
With Brain, Computer starts each task with full context of your projects, decisions, and sources instead of from scratch. On tasks that require past context, Brain improves answer correctness by 25%, recall by 16%, and runs 13% cheaper per task.
Every memory links back to the session, file, or source it came from with full transparency and control. You can access Brain and your saved memories under "Customize" in the sidebar. Read more about Brain: https://t.co/lExdtp176d
Context
Perplexity's Brain is designed to carry project between Computer tasks while preserving where that context came from. The company describes a context graph that connects past work, decisions and sources, with each saved memory linked to its originating session, file or source. A user can therefore inspect the basis of a remembered detail instead of treating it as an unexplained assertion. Brain launched as a research preview for Max subscribers, with saved memories accessible through Customize. The announcement describes these controls.
