I will build a rag chatbot and ai agent on your own data with langchain


Level 1
Über diesen Service
I build chatbots that answer from your data, with citations, so you can check every answer.
Most chatbot builds fail the same way: the bot sounds confident and invents things. I build retrieval-first, so every answer traces back to a source document you can open.
What I build:
- RAG chatbots over your PDFs, docs, spreadsheets, and internal wikis
- Chat over video and audio libraries using transcription and on-screen text extraction
- Source citations on every answer
- Vector search with FAISS or your preferred store
- Chat API or a simple web interface
- Ingestion pipelines that keep the index current as your data grows
Why me:
- 5+ years building production AI systems
- Built a multi-source retrieval system as graduate research: Whisper transcription, OCR, FAISS vector search, LangChain query layer
- LREC 2026 published paper; public dataset and model on Hugging Face
- 45 orders completed, 20 five-star reviews, repeat clients
Have video or audio, not just documents? That is the Premium tier, and it is the part most sellers cannot do. I transcribe, extract on-screen text, and index both so your bot can answer from footage.

FAQ
How is this different from just uploading files to ChatGPT?
Your data stays in your own index, answers cite their sources, it scales past upload limits, and it plugs into your product through an API.
Will it make things up?
Retrieval-first design with citations makes that far less likely, and you can verify any answer against the source.
What formats can you ingest?
PDFs, Word, text, CSV, HTML, and scraped pages. Video and audio on the Premium tier.
Which model does it use?
Your choice: Claude, GPT, or an open model you host. I can also make it swappable.
Do I get the code?
Yes. Full source, documentation, and setup instructions.
Can you connect it to my existing app?
Yes, that is what the chat API is for.
