Chat with AI

Chat with AI is the in-editor AI chat app that helps with your editing and coding tasks. Use it to get help, refactor and generate code, or get quick explanations — all without leaving your editor.

Supported Providers

Chat with AI supports the OpenAI, Deepseek, Google, and LM Studio (OpenAI-compatible) providers. For cloud providers, you’ll paste an API key into the plug-in settings; for LM Studio, you can run models locally and connect without an API key. This flexibility means you can prioritize privacy, cost, or performance based on your workflow.

Quick Install

View the help page for installation details and step-by-step instructions. It covers the Desktop Installer and Portable methods as well as LM Studio setup.
An API key is required for OpenAI, Deepseek, or Google providers. You may find Google’s free trial to be the most convenient option.

Core Capabilities

Key features of Chat with AI include:

  • Threaded conversations that preserve context within each chat.

Why Chat with AI Stands Apart

Chat with AI is integrated into EmEditor. You don’t need to open other AI chat apps when EmEditor is already open. There are features like Copy to Editor or tool calling that enables the AI to directly modify your document.
The plug-in emphasizes privacy. Chat with AI directly connects to the provider API for AI requests instead of relying on a proxy server. LM Studio support gives you the option to run models locally without internet connection.
You will find that using provider APIs is often much cheaper than subscribing to services such as ChatGPT. To give an example of API prices, GPT-5 mini is priced at $0.25 per 1 million input tokens (as of Aug 2025).

Customizable Settings

The Settings dialog lets you tailor the app to your preferences:

  • Choose the AI provider
  • Pick a model and tweak AI parameters
  • Enable individual tools for tool calling
  • Set UI options
