Vir is a knowledge management tool that automatically extracts valuable insights from AI coding assistant sessions and stores them as organized notes in your personal notes app. It reads your past conversations, identifies patterns, gotchas, decisions, and tool usage notes, then writes them as searchable markdown files organized by category and project. The tool runs on a schedule to process new sessions, or can be run manually, and integrates with Claude Code so future AI sessions can consult your accumulated knowledge. It uses your AI service account to analyze conversations and can optionally use local embedding models for semantic search. The knowledge flows from your AI sessions into your vault, and the most useful notes get injected back into your AI assistant's memory so it learns from past work.
How It Works
You work with an AI coding assistant that helps you build software, creating a record of every decision and solution.
You keep your project notes in an app like Obsidian where you organize everything with links and tags.
You run a simple install command and vir guides you through connecting your notes app and AI service.
The first time you run it, vir reads through all your past AI conversations and pulls out the useful bits—patterns you discovered, mistakes you fixed, and decisions you made—then writes them as clean notes in your vault.
vir sits in the background and checks for new AI conversations every few hours, adding fresh insights to your vault without you thinking about it.
You run it whenever you want to process new conversations and refresh your knowledge.
Later, when you're stuck on something, you ask vir questions and it searches through your accumulated wisdom to find relevant patterns and gotchas from past projects.
vir puts the most important knowledge into your AI assistant's memory file so it starts every new conversation already knowing about your past work.
Each new AI session adds to your knowledge vault, making every future session smarter than the last.
