Notion AI helps you work with what is written in Notion. Heidi builds a brain from everything, meetings, chat, tickets, docs, code, and then acts on it: agents, long jobs, and an API every AI tool can read.
Workspace AI assistants are bounded by their workspace. The knowledge that matters most, decisions made in meetings, promises made in chat, context in tickets, mostly never reaches the wiki.
Heidi captures across systems, keeps sources and permissions on every fact, and does not stop at answering: she runs teammates and scheduled work against that memory. If Notion is one of your sources, connect it and it feeds the brain too.
