- Hybrid retrieval
- Source evidence
- Cited answer
Built for sales questions
A Vietnamese-first assistant for looking up specifications, pricing, promotions, warranty terms and sales policies in approved internal documents. The knowledge tools support search, excerpts, document metadata and evidence comparison.
From documents to searchable knowledge
The ingestion pipeline supports Google Drive, Google Docs and Sheets, PDF, DOCX, XLSX, CSV and text. It includes OCR for scanned PDF pages, document versions and incremental updates to the knowledge index.
Retrieval with source evidence
Keyword and semantic retrieval combine in PostgreSQL with pgvector. Results carry document references, versions and page information where available, so answers can be checked against their source.
Access boundaries around the answer
The implementation limits Telegram access to the configured group and checks document permissions during retrieval and excerpt reads. Cached results are rechecked against current access. When approved evidence is missing, the assistant returns a clear unavailable response.
