Local RAG app for question answering from PDFs, fully offline

A Flask-based local RAG application that lets users upload PDFs, chunk and embed them, then ask questions answered solely from the document content. It uses Ollama for chat and embedding models, ChromaDB as vector store, and runs entirely offline, solving privacy and data control needs for users who want to query their own documents without sending data to external services.

The app processes PDFs by splitting them into overlapping chunks to preserve sentence continuity, generates embeddings via Ollama, stores them in ChromaDB with PersistentClient, and answers questions using a local chat model. Tech stack: Flask, Ollama, ChromaDB. No traction signals beyond the post.

Wigolo: MCP server giving LLM coding tools live web access with crawling and caching

Wigolo is an open-source MCP server that runs locally and provides LLM coding tools (Claude Code, Cursor, Codex, Gemini CLI) with ten web tools: multi-engine search with reranking, page fetching for JavaScript-heavy sites and PDFs, whole-docs-site crawling, structured extraction, and persistent local caching. It solves the problem of LLMs relying on stale training data by giving them real-time web access.
