Llamail: Private Local AI Email Agent
A developer built Llamail, a private, local AI email agent (persona: Sable) that runs entirely on personal hardware and exposes a Telegram bot interface. The project uses llama.cpp with a Llama 3.1 8B model (Q8_0) for inference, Nomic Embed v2 MoE for embeddings, FastAPI as the application layer, n8n in Docker as a lightweight orchestrator for Gmail/Telegram events, and SQLite (WAL) plus ChromaDB for storage and semantic search. Workflows include RAG-based search, live incoming-email processing, draft generation, campaign personalization, and reply tracking. Reported performance: email summarization 2–3.5s, embeddings <0.1s, bulk import ~5 emails/min, RAG Q&A ~7s. Source code is published at github.com/sviat-barbutsa/llamail.
Demonstrates a practical, privacy-first local LLM application for email workflows and RAG search; relevant to teams exploring on-device inference, cost trade-offs, and first-party data handling but not a major platform update.

Key Takeaways & Evidence Grounding
- Author built Llamail, a private local email agent with a configurable persona named Sable.
- Inference uses llama.cpp + Llama 3.1 8B (Q8_0); embeddings use Nomic Embed v2 MoE (Q6_K).
- Architecture: FastAPI backend, n8n in Docker for Gmail/Telegram event bridging, SQLite (WAL) + ChromaDB for storage/search, and a Telegram bot interface.
- Performance benchmarks reported: summarization ~2–3.5s, embedding <0.1s, bulk import throughput ~5 emails/min, RAG Q&A ~7s.
- Source code repository: github.com/sviat-barbutsa/llamail.

LLM-as-Router for a Local Telegram Email Agent
A technical how-to describing an architecture that uses a local LLM as an intent router for a private Telegram-based email agent (Llamail). The author explains a three-tier router (slash commands, safe direct compound commands, and LLM classification for natural language), the Jinja2 classifier prompt that returns JSON intents/params/confidence, and a dispatch registry (COMMAND_DISPATCH / INTENT_DISPATCH) that maps labels to deterministic Python handlers. The article details implementation choices (hybrid retrieval with ChromaDB + SQLite FTS5, llama.cpp for local inference), UX touches (immediate Telegram 'Analyzing your message...' notifier), and how to add new intents while keeping prompt and dispatch table in sync. Code is available at github.com/sviat-barbutsa/llamail.
Private Local LLM Queries Git and Project Data
A developer built a private, offline AI assistant that answers natural-language questions about git history and project-management data by translating user questions into SQL. The system ingests commits and project board data into a single SQLite database (via Python collectors), uses an auto-discovery step to surface exact values, and runs a local LLM (Ollama with qwen2.5-coder:7b) to generate Text-to-SQL queries and summarize results. The project emphasizes privacy (no cloud or API keys), avoids vector RAG/embedding stores for structured data, and is implemented as a small CLI codebase (~8 files, ~400 lines). Planned enhancements include hourly refresh cron jobs, adding chat history as a data source, and a simple web UI.
Build Local LLM Chatbot with Ollama and Python
A step-by-step tutorial showing how to run a local Large Language Model (LLM) chatbot on a personal machine using Ollama and Python. The guide explains installing Ollama, pulling an open-source model (example: Llama 3.2), setting up a Python virtual environment, installing packages (langchain, langchain-ollama, ollama), and provides a complete example script that maintains conversation history. It also outlines customization options such as switching models (phi3, mistral, gemma), adding a web UI (Streamlit or Flask), and implementing RAG with LangChain and ChromaDB. The article emphasizes privacy benefits of local inference and offers troubleshooting tips for model availability, performance, and memory.
