Production-Grade Retrieval Pipeline

Not a basic vector search. A multi-stage pipeline that finds the right answer every time.

🔍

Hybrid Search

Combines dense vector similarity with PostgreSQL full-text keyword search. Fused with weighted Reciprocal Rank Fusion.

🧠

Query Expansion & HyDE

AI generates alternative phrasings and a hypothetical answer passage to improve recall for ambiguous queries.

📊

LLM Reranking

After retrieval, an LLM scores each candidate for relevance. Low-quality results are filtered before reaching the prompt.

📄

Parent Document Retrieval

Small chunks for precise matching, large parent chunks for rich context. Adjacent chunk expansion as fallback.

🎯

MMR Diversity

Maximal Marginal Relevance prevents duplicate content in results, ensuring diverse and useful context.

🕷️

AI Content Refinement

Crawled web pages are cleaned by AI before chunking — removing navigation noise, cookie banners, and boilerplate.

Provider-Agnostic by Design

Every layer is pluggable. Switch AI providers, vector stores, or voice engines without changing your workflows or knowledge base.

🤖

7 AI Providers

Vertex AI, OpenRouter, DeepSeek, BytePlus, Alibaba for text. OpenAI Realtime and Nova Sonic for voice. Fallback and circuit breaker built in.

🗄️

6 Vector Stores

pgvector (default), Qdrant, Pinecone, Weaviate, Milvus, Chroma. Embedding space isolation prevents mixing incompatible vectors.

🔌

12+ Connectors

Google Calendar, Shopify, Twilio, and more. Each connector exposes actions as AI tools and workflow steps. Add your own with one PHP class.

Your Infrastructure, Your Control

Deploy on your servers and maintain complete ownership.

🔐

Data Privacy

Customer conversations never leave your servers. Meet GDPR, HIPAA, and other compliance requirements.

💰
