Building Shared Memory For Ai Agents In Notion

Notion’s Lore stores lessons from agent sessions in shared pages that later sessions can retrieve. Its engineering article describes keeping procedures, decisions and other reusable knowledge accessible to both people and agents, with expiration and maintenance tools to manage stale information.

Notion’s own evaluation used coding scenarios chosen because models could not reliably complete them without Lore. In 149 paired scenarios, agents with a memory collection seeded with relevant information passed 102, versus 82 without it. Memory helped in 27 scenarios and hurt in 7. Notion did not benchmark its messier team-created collection, which its own sampling suggests contains duplicates and low-value notes. The evidence supports relevant, retrievable memory as an aid on these hard tasks; it leaves the benefit of accumulating unmaintained session notes unresolved.
