Convex is a full-stack development platform and cloud database, including built-in vector search. In this third post in our [series](https://stack.convex.dev/ai-chat-using-openai-assistants-api), we’ll build an AI-powered chat interface using Convex, with our own message storage and context retrieval.

Your document is safely stored, but search is coming up empty? Inconsistent search systems can really confuse users! Don't worry–in Convex, transactional search indexing ensures that users always get what they expect and your apps just work.
