Mature Python/JS framework for building RAG pipelines, composable loaders, splitters, vector stores, and retrieval chains with full production flexibility.
Code-first. requires Python experience. More boilerplate than visual builders like Dify or Flowise.
Provides efficient vector similarity search with semantic embedding storage.
When you need traditional keyword or full-text search.

Upload PDFs directly in ChatGPT Plus and query them in chat, quickest zero-setup option for one-off document Q&A without building a pipeline.
File uploads are session-scoped. not a scalable or programmable RAG solution for production apps.
RenderTargetPool supports devtools workflows.
Premium needed for priority support.

Self-hosted chat UI with built-in RAG over local documents, connects to Ollama or any OpenAI-compatible API with zero data leaving your server.
Requires Docker and a local or private LLM. not a no-code option for non-technical teams.
Handles ingestion, indexing, and retrieval with strong anti-hallucination scoring.
Proprietary platform limits customization of the retrieval pipeline.
Delivers correlation specifically designed for rag over your documents.
Not ideal if your rag over your documents requires extensive manual customization.
RDFox is a semantic RDF database engineered for complex inference and reasoning over linked data.

Copy and paste these prompts into your chosen tool to get started.
Fill in placeholders (optional):
I have a RAG system that works for simple questions but fails on multi-hop queries. How do I implement query decomposition or chain-of-thought retrieval?
Write a hybrid search implementation that combines keyword search (BM25) and semantic search (embeddings) for better RAG retrieval: [describe current setup]
Implement a re-ranking step after initial retrieval using a cross-encoder model. Show the code and explain the performance tradeoff.
My RAG system hallucinates when the answer isn't in the documents. Write a grounding check that returns 'not found' instead of a fabricated answer.
Design a RAG architecture that handles [X] million documents efficiently. Address: indexing strategy, chunk size optimization, caching, and latency targets.
Write an evaluation framework for a RAG system. Measure: faithfulness, answer relevance, context precision, and context recall using [RAGAS or custom evaluation].
