Logseq Integration

Logseq is an open-source knowledge management and note-taking application with outliner-style editing. Its AI features support custom LLM providers for intelligent note assistance.

Logseq's AI plugin supports custom OpenAI-compatible endpoints.

Prerequisites

An LLM API account with an API key
Logseq 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 Logseq

Open Logseq and navigate to Settings → Plugins.
Install or open the AI/LLM plugin settings.
Select "OpenAI Compatible".
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.

Test the Integration

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

Logseq's block-based structure works well with AI for organizing and expanding your notes.

Benefits of Using LLM API with Logseq

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
