Obsidian Smart Connections Integration
Smart Connections is an Obsidian plugin that uses AI to find connections between your notes and provide an AI chat interface that understands your knowledge base.
Smart Connections supports custom API endpoints for its AI features.
Prerequisites
- An LLM API account with an API key
- Obsidian Smart Connections 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)
INFO
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 Smart Connections
- Open Obsidian Settings → Smart Connections.
- In the "Chat Model" section, select "Custom / OpenAI-compatible".
- Enter:
- API Key: paste the key you copied from app.llmapi.ai/dashboard/api-keys
- API URL: https://api.llmapi.ai/v1
- Model: openai/gpt-4o
- Close settings.
Test the Integration
Verify that Obsidian Smart Connections can successfully communicate with LLM API by sending a test request. All requests will now be routed through LLM API.
INFO
Smart Connections' AI chat can answer questions about your notes using LLM API models.
