AI memory systems: semantic memory stores facts, long-term memory preserves context

3. Semantic memory
Stores factual knowledge and concepts.
Examples:
- Python is a programming language.
- LangGraph is used for AI agents.
- Neo4j is a graph database.
Useful for knowledge assistants, educational systems, and AI research tools.
This is the “what” memory of AI systems.
2. Long-term memory
Stores information across multiple interactions.
Examples:
- User preferences
- Historical conversations
- Project information
- Persistent knowledge
Without long-term memory, every conversation starts from zero. It is what makes AI systems feel personalized and intelligent.
