Chat with a local model
A classic chat window, but the AI runs on your computer. Your messages and history stay on your drive.
LM Studio is a free desktop app. It downloads an AI model to your machine, then you chat with it in a window, as you would with ChatGPT, but without the internet. Since July 2026, the vendor also offers “Bionic,” a second app that takes on a complete piece of work on your documents.
LM Studio has a free plan. The recommended plan to start with: Free, $0. Prices checked on October 3, 2026 on the vendor’s official page.
Who it’s for: anyone who wants to try offline AI with a real app, with buttons and menus, and no commands to type.
A classic chat window, but the AI runs on your computer. Your messages and history stay on your drive.
A built-in catalog, powered by Hugging Face. You search by name and download in one click. You can install several and switch between them.
You attach a PDF, a Word file, or a text file to the conversation. If the document is short, the AI reads all of it. If it is long, LM Studio searches it for the passages relevant to your question.
