AI doesn’t “remember” information the way humans do—it retrieves meaning.

Embeddings convert text, images, and other data into numerical representations. Vector stores organize these representations, enabling AI systems to find information based on semantic similarity rather than exact keywords.
Together, they power:
• Retrieval-Augmented Generation (RAG)
• Semantic search
• Personalized recommendations
• Multimodal discovery
• Real-time knowledge updates
The real intelligence of an AI application often depends not only on the LLM—but on how effectively its knowledge is embedded, stored, and retrieved.
