Built upon the Pi agent, piFlow lets you import local documents to build a private knowledge base. Ask questions in natural language, and get answers with source citations—every response traces back to the specific document and paragraph. All documents, vector indexes, and chat history are stored in a local SQLite database, with zero cloud dependencies.

Supports PDF (including scanned documents with OCR), Markdown, TXT, HTML, and more. You can choose your generation backend: local GGUF, remote Ollama, or DeepSeek. The app is built with Tauri 2 + Node dual‑process architecture. continuously improving it — contributions and feedback are always welcome!
