Run Copilot for Obsidian on O3 Mini
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, its bring-your-own-key setup needs no Copilot license, and Opper is one of the providers in its catalogue: pick Opper, paste your key, and your vault runs on any of 700+ models, with your notes going only to the model you chose.
