I will build a chat with PDF and database ai assistant
Vikant Sharma
Over deze dienst
Do you need an intelligent AI system that can read, extract, and accurately answer questions from your private documents? I will build a production-grade Document AI and RAG solution tailored to your files and business data.
Supported Document Formats:
- PDFs, scanned reports, and research papers
- Excel spreadsheets & CSV files
- Word documents (DOCX), Markdown, and TXT
- Knowledge bases (Notion, Google Drive, SQL dumps)
Technical Capabilities:
- Accurate Source Citations: Every answer references the exact page and source paragraph to prevent hallucinations.
- Vector Embeddings & Hybrid Search: Pinecone, Chroma DB, FAISS, or PGVector for fast semantic retrieval.
- LLM Integrations: OpenAI (GPT-4o), Anthropic Claude 3.5, or 100% private local models via Ollama (Llama 3, Mistral).
- Table & Structure Parsing: Accurately extracts numbers and financial tables without losing structure.
- Full-Stack UI: Clean, intuitive React frontend where you can drag-and-drop new files and chat in real-time.
Senior Full-Stack & AI engineer. Clean code with full documentation.

Veelgestelde vragen
How does the bot avoid hallucinations when reading my documents?
We implement strict Retrieval-Augmented Generation (RAG) guardrails. The AI is restricted to answering exclusively from the retrieved document chunks and includes precise citations (such as page numbers and document titles) for every fact it outputs.
Can the AI read complex tables, charts, or scanned PDFs?
Yes. For standard digital PDFs and spreadsheets (CSV/Excel), text and tabular structures are parsed directly. For scanned documents or image-heavy PDFs, we integrate OCR pipelines (such as Unstructured or Tesseract) to extract tables and text accurately.
Can this run completely offline without uploading my data to third parties?
Yes. If privacy or compliance is a priority, I can deploy the solution using local open-source LLMs (like Llama 3 or Mistral via Ollama) and a local vector database (like Chroma). Your documents never leave your server or local machine.
How do I add or update documents later?
In the Standard and Premium packages, the system is designed to dynamically ingest new files. You can drop new PDFs, CSVs, or text files into an upload directory or frontend interface, and the pipeline automatically chunks, embeds, and updates the vector database.
