# Memory > What the crew remembers, where each memory came from, and who it reaches. Source: https://docs.cruma.ai/concepts/memory/ The crew doesn't start from nothing each time. Everything it remembers is something you can see, with where it came from and when, and you can correct it. ## Noted for next time When you teach the crew something outright in a chat, like a correction, "we always…" or "never…", it keeps it straight away. The chat shows **Noted for next time:** and the lesson, with **Undo**. Every lesson keeps the message it came from. A lesson about one client is used only for that client. ## Lessons Cruma infers After a chat goes quiet, the crew looks back over it and may notice a lesson nobody said outright. Those wait for your OK. The chat shows "Cruma learned 1 thing from this chat" with the lesson and where it came from, and **Keep** or **Dismiss**. Kept, it says who will use it: "Kept. Research and Social will use it for Lumen." Waiting lessons also show on the crew member's page, under **What it has learned**. The crew relies only on lessons someone kept. ## What you tell it about yourself Tell a crew member something about yourself, like "Remember that I like numbers in a table," and it goes straight in. Its answer shows **Remembered:** and what it saved, with **Undo**. From then on, the crew keeps it in mind when you ask. ## Thumbs up and down **Good answer** and **Bad answer** tell the crew how it did. **Bad answer** asks "What was off? The crew learns from it." Your reason goes to whoever answered, and it can become a lesson. ## Facts about your work As the crew reads your email, files and chats, it proposes facts about your records: a deadline, an audience, who prefers what. Each fact has its source, how sure the crew is, and "as of" when it was last confirmed. A proposed fact shows dashed until someone keeps it. See [Types and records](/concepts/types-and-records/). Facts carry their age. An old fact is flagged ("last confirmed 3 years ago") before anyone relies on it, and the crew re-checks important ones from new email and files. A correction never erases what was believed before, so "what did we think in March?" always has an answer. ## Who a memory reaches Every memory keeps the audience of where it came from. A fact learned from a Finance file stays with Finance wherever it's used. When the crew answers in a chat, it uses only what everyone in that chat may see, so a lesson from a small chat never reaches a wider one. What one person told the crew about themselves stays with that person. ## Tidy over time The crew's memory is kept tidy, not just added to: lessons are merged, duplicates removed and outdated rules retired, and each still shows when it was learned and last used. ## Long chats The crew reads the latest part of a chat word for word, and keeps notes on everything older: short items, each pointing back at its message, so a decision or a number from an hour ago isn't lost. In the chat, a line marks where the notes begin, with **Show notes**.
