AI document assistant

Multi-format document workspace with semantic search, transcription-aware Q&A, and source-grounded answers across PDFs, Office files, tables, and media.

Results at a glance

PDF, Word, Excel, CSV, JSON, and audio/video ingestion

Semantic retrieval with citation-style sourcing

Interactive exploration without brittle keyword-only search

Challenge

Teams needed a single place to upload heterogeneous documents and media, search by meaning rather than filenames alone, and ask questions that respect the underlying sources instead of producing unattributed guesses.

What Habrig built

  • Streamlit-based operator UI for uploads, corpus browsing, and chat-style Q&A scoped to selected documents
  • Clear separation between retrieved excerpts and model answers to keep outputs auditable
  • Embedding and indexing pipeline suitable for mixed modalities with chunking tuned per file type
  • Retrieval layer combining dense semantic search with filters for document sets and formats
  • Optional transcription path for audio/video aligned to the same retrieval stack
  • GPU-backed inference where latency and throughput warrant it, with fallbacks for lighter deployments
  • Repeatable environment definitions so demos can move from laptop to a small server without rework

Outcomes

  • Faster answers across large document sets without manual tagging every file
  • Reduced “trust but verify” loops thanks to source-grounded responses
  • A reusable pattern for internal knowledge bases and customer-facing doc portals

Technology

frontend

Streamlit UI focused on upload, search, and grounded Q&A flows

backend

Python services for ingestion, embeddings, retrieval, and orchestration (including T5-class tooling where appropriate)

database

Vector-oriented retrieval with metadata for filenames, types, and source spans

infrastructure

Deployable on modest GPU or CPU hosts depending on corpus size and SLA

monitoring

Structured logs around ingestion jobs, query latency, and retrieval misses

cicd

Scripted checks and pinned dependencies for reproducible analyst-facing builds
