Copilot for Obsidian puts an AI assistant inside your Obsidian vault: chat with your notes, generate and rewrite content, and query your whole knowledge base without leaving the app. It is open source, and its bring-your-own-key setup takes custom OpenAI-compatible providers with no Copilot license required. Add Opper as that provider and your vault runs on any of 700+ models, with your notes going only to the model you chose.
Copilot for ObsidianoninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
