Obsidian Copilot Integration

Obsidian CoPilot is a plugin for the Obsidian knowledge management app that adds AI-powered features including chat, text generation, summarization, and semantic search across your notes vault.

Obsidian CoPilot supports custom OpenAI-compatible endpoints in its plugin settings.

Prerequisites

An LLM API account with an API key
Obsidian Copilot installed or accessible

Setup

Get Your LLM API Key

Log in to your LLM API dashboard
Click Create Key to Start
Copy your new API key immediately — it will only be shown once
Store the key securely (e.g., in a password manager or .env file)

LLM API is an OpenAI-compatible gateway that gives you access to dozens of AI models through a single API key and endpoint.

Configure LLM API in Obsidian CoPilot

Open Obsidian and navigate to Settings → Community Plugins → CoPilot.
In the CoPilot settings, find the LLM Provider section.
Select "OpenAI" or "Custom" as the provider.
Enter:
- API Key: paste the key you copied from app.llmapi.ai/api-keys
- Base URL: https://api.llmapi.ai/v1
Set the model name.
Close settings and use CoPilot in your vault.

Test the Integration

Verify that Obsidian Copilot can successfully communicate with LLM API by sending a test request. All requests will now be routed through LLM API.

CoPilot can search and summarize your entire Obsidian vault using LLM API's models.

Benefits of Using LLM API with Obsidian Copilot

Multi-Provider Access: Use models from OpenAI, Anthropic, Google, and more through a single API
Cost Control: Track and limit your AI spending with detailed usage analytics
Unified Billing: One account for all providers instead of managing multiple API keys
Caching: Reduce costs with response caching for repeated requests
