# Things that make them smart *Hire and onboard* Upload documents, connect Notion or Google Docs, and train your AI agents on your actual business knowledge. A 6-layer memory system ensures they never forget a conversation, a decision, or a preference. When one employee learns something new, the whole team benefits through shared knowledge. An AI employee is only as good as what it knows about your business. Upload documents, connect knowledge bases, and feed internal processes directly to your employees. Knowledge lives in a 6-layer memory system that prevents forgetting. Short-term context, long-term facts, past experiences, learned procedures, entity relationships, and shared team memory all work together. When one employee learns something new, the entire team benefits through shared knowledge. Train once, apply everywhere. ## At a Glance - **6** Memory layers - **100%** Retention across sessions - **0** Duplicate training needed ## Use Cases ### Train your employee on internal docs Upload SOPs, product manuals, and policies. Your AI employee reads and retains them, so answers reflect your actual processes rather than generic knowledge. ### Let employees remember past conversations The 6-layer memory system captures preferences, decisions, and context over time. Employees recall what was discussed last week and build on it, not start fresh every session. ### Share knowledge across the team Add documents to shared knowledge so every AI employee on the team draws from the same source of truth. One update propagates everywhere, instantly. ### Keep knowledge fresh as your business changes Update training documents any time. Your AI employee picks up the changes on the next interaction, so they stay current without manual re-configuration. ## Features in this Category - **[Train on Your Knowledge](/en/features/knowledge/knowledge-training)** — Upload documents and connect tools like Notion or Google Docs so your employee understands your business deeply. - **[Memory That Never Forgets](/en/features/knowledge/memory-system)** — Six distinct memory layers ensure your employee remembers conversations, learns from experience, and recalls trained knowledge instantly. - **[Shared Team Knowledge](/en/features/knowledge/shared-knowledge)** — Train one employee and the whole team learns, so you never explain the same thing twice.
