What it is

Obsidian Copilot is the plugin to pick if you keep your notes in Obsidian and want a local LLM wired directly into your writing flow. It bridges to Ollama or any OpenAI-compatible endpoint, so you can run a model like Llama 3.1 8B Q4_K_M on your own hardware and keep everything offline. Inline chat, selection summarization, and vault-wide search-and-ask all work without leaving your editor. Pair it with Smart Connections for RAG over your full note corpus. The catch: mobile use requires a reachable LAN endpoint, and the best vault-context features lean on Obsidian Sync or a self-hosted server.

✓ Strengths

  • +Mature, frequent releases
  • +Vault-wide context-aware features
  • +Cross-platform with Obsidian

△ Caveats

  • −Best features need Obsidian Sync or self-hosted endpoint
  • −Mobile usage requires reachable LAN endpoint
