One memory across all of them. Shared spaces, where teammates recall each other's decisions, come with a Team seat.

“Our team works from one shared memory. When someone picks up our algorithm work, their coding agent already knows what everyone else has tried and why, so we build on each other's work instead of repeating it. Day to day, it's also made my LLM interactions more productive.”
