Converts uploaded documents into vector embeddings using local language models, storing them in a local vector database without sending data to external servers. Uses retrieval-augmented generation (RAG) architecture where documents are chunked, embedded via local transformers, and indexed for semantic search. The entire embedding pipeline runs on-device, enabling privacy-preserving document understanding without cloud dependencies.
Unique: Runs entire embedding pipeline locally using open-source models (Sentence Transformers, LLaMA embeddings) rather than relying on OpenAI/Cohere APIs, eliminating data transmission and API costs while maintaining full control over model selection and inference parameters
vs alternatives: Stronger privacy guarantees than cloud-based RAG systems (Pinecone, Weaviate Cloud) because documents never leave the local machine; trade-off is slower embedding speed and requires local compute resources
Answers questions about uploaded documents using a locally-running large language model, combining retrieved document chunks with the LLM prompt to generate contextual answers. Implements a retrieval-augmented generation (RAG) loop where user queries are embedded, matched against indexed documents, and the top-K relevant chunks are injected into the LLM context window before generation. No query or document content is sent to external LLM APIs.
Unique: Integrates local embedding retrieval with local LLM inference in a single privacy-preserving pipeline, allowing users to swap LLM models (Ollama, LM Studio, vLLM) without changing the retrieval layer, and supports quantized models (GGML, GPTQ) for resource-constrained environments
vs alternatives: Eliminates per-query API costs and data exposure compared to ChatGPT+Retrieval plugins or LangChain+OpenAI stacks; slower inference but complete data sovereignty and model flexibility
Exports QA results (questions, answers, source documents) in multiple formats (JSON, CSV, Markdown, PDF) for sharing, archival, or integration with other tools. Supports batch export of entire chat sessions or individual Q&A pairs. Includes options for including/excluding source document references, metadata, and confidence scores in exports.
Unique: Supports multiple export formats with configurable content inclusion, enabling flexible sharing and integration with downstream tools while maintaining source attribution and metadata
vs alternatives: More flexible than copy-paste or screenshot sharing; comparable to ChatGPT's export features but with more format options and control over included content
Exposes Private GPT functionality through a REST API or Python SDK, enabling developers to integrate document QA, semantic search, and embedding capabilities into custom applications. Supports authentication (API keys), rate limiting, and request/response serialization. Allows programmatic control over document indexing, querying, and model configuration without using the GUI.
Unique: Provides both REST API and Python SDK for programmatic access to document QA and embedding capabilities, enabling integration with custom applications and workflows
vs alternatives: More flexible than GUI-only tools; comparable to LangChain's integration layer but tightly coupled to Private GPT's specific implementation and local-first architecture
Searches across multiple documents using semantic similarity rather than keyword matching, embedding the user's search query and comparing it against indexed document chunks to return contextually relevant results. Uses cosine similarity or other distance metrics to rank chunks by relevance, enabling users to find information even when exact keywords don't match. Supports filtering by document metadata (filename, date, tags) before semantic ranking.
Unique: Implements semantic search entirely locally using open-source embedding models and vector databases, avoiding dependency on proprietary search APIs (Elasticsearch, Algolia) while maintaining full control over ranking algorithms and metadata filtering
vs alternatives: More semantically aware than keyword-based search (grep, Ctrl+F) and avoids cloud API costs compared to Azure Cognitive Search or AWS Kendra; slower than optimized cloud search for massive corpora but better privacy
Accepts documents in multiple formats (PDF, DOCX, TXT, MD, CSV) and converts them to a unified text representation for embedding and indexing. Uses format-specific parsers (PyPDF2 for PDFs, python-docx for DOCX, CSV readers) to extract text while preserving document structure metadata (page numbers, section headers, table information). Handles OCR for scanned PDFs if enabled, converting image-based text to machine-readable format.
Unique: Integrates multiple format parsers with optional OCR in a single pipeline, automatically detecting document type and applying appropriate extraction logic, while preserving source document metadata for traceability
vs alternatives: More flexible than single-format tools (PDF-only readers) and avoids manual format conversion; slower than cloud document processing services (AWS Textract) but runs locally without API costs or data transmission
Splits documents into overlapping text chunks optimized for embedding and LLM context windows, using configurable chunk size (typically 256-1024 tokens) and overlap percentage (10-50%) to preserve context across chunk boundaries. Implements smart chunking that respects document structure (paragraph breaks, section headers) rather than naive fixed-size splitting, ensuring semantic coherence within chunks. Metadata (source document, chunk index, page number) is attached to each chunk for source attribution.
Unique: Implements structure-aware chunking that respects paragraph and section boundaries rather than naive token-based splitting, combined with configurable overlap to preserve context, and attaches rich metadata for source attribution
vs alternatives: More sophisticated than simple fixed-size chunking used in basic RAG implementations; comparable to LangChain's recursive character splitter but with tighter integration to Private GPT's embedding and retrieval pipeline
Stores vector embeddings and document metadata in a local vector database (e.g., FAISS, Chroma, or SQLite with vector extensions) that persists across sessions, enabling users to build and reuse document indexes without re-embedding on each startup. Supports incremental indexing where new documents are added to existing indexes without rebuilding from scratch. Provides basic CRUD operations (create, read, update, delete) for managing indexed documents.
Unique: Provides transparent persistence layer for local vector databases with incremental indexing support, allowing users to build and maintain document indexes without cloud dependencies or per-query API costs
vs alternatives: Simpler and more privacy-preserving than cloud vector databases (Pinecone, Weaviate Cloud) but with limited scalability; comparable to Chroma's local mode but tightly integrated with Private GPT's embedding and retrieval pipeline
