txtai is an all-in-one embeddings database for semantic search, LLM orchestration and language model workflows. Embeddings databases enable vector search over text, documents, audio, images and video. Workflows integrate large language model (LLM) prompt chains, summarization, transcription, translation and more to build intelligent applications.

txtai provides the following features.

• 🔎 Vector search with SQL
• 💡 Pipelines powered by language models
• ↪️️ Workflows to join pipelines together and aggregate business logic
• ☁️ Run local or scale out with container orchestration
