The Overview

VaultMail is a full-stack web application that bridges your Obsidian knowledge base with AI-powered email drafting. Upload your vault, and VaultMail parses every Markdown file, chunks and embeds the content using Google's Gemini Embedding API, and indexes it into a Qdrant vector database. When you describe an email, it retrieves the most relevant notes and drafts a context-aware email using Gemini Flash — grounded in your own words. It also features Gmail SMTP integration to send finalized emails directly from the app, all wrapped in a premium 'Obsidian Terminal' custom dark theme.
