The Complete Open Source RAG Ecosystem
Four modular Python tools that cover the full production RAG lifecycle. From raw documents to verified, regression-tested responses. Use each independently or combine for an end-to-end pipeline.
Each tool solves one stage of the RAG lifecycle. Use them together or independently.
Document Intelligence for RAG
Converts PDFs, DOCX, PPTX, XLSX into validated, AI-ready chunks with 6 hybrid chunking strategies and HITL review.
pip install "longparser[gpu]"Production RAG Framework
Multi-tenant RAG chatbots with persistent memory, streaming, tool calling, and 9 vector DB providers. 10 lines to production.
pip install longtrainerHallucination Detection
Verifies every claim against source documents using STS + NLI pipeline. No LLM dependency. Trust scores and claim-level tracing.
pip install longtracerWhether you are evaluating our engineering quality or building your own RAG system.
Stop wiring together dozens of libraries. Get production-ready RAG components that work out of the box.

Schedule ConsultationStart with what you need most. Each tool works independently.
Every tool in the Long Suite was extracted from production client projects. LongTrainer powers multi-tenant chatbots serving thousands of users. LongParser processes enterprise documents in regulated industries. LongTracer verifies AI outputs in healthcare and legal. LongProbe catches regressions in CI/CD pipelines.
We open source them because the best way to prove engineering quality is to show your work. If you like what you see, imagine what we can build for your specific use case.
Use commercially. Modify freely. No restrictions.
Built for real workloads, not tutorials.
Regular releases and bug fixes.
Integrates with LangChain and LlamaIndex.
We use the Long Suite in production for enterprise clients across healthcare, fintech, legal, and SaaS. Let us build yours.
