AnythingLLM vs ChatGPT: rent an assistant or run an open-source system?
ChatGPT is a closed assistant you rent from OpenAI, and AnythingLLM is an open-source app that chats with your documents on your own machine. Kortix is the open-source AI Operating System you own, where agents, skills, memory and connectors live in one git repo.
Three layers: a closed assistant, a document app, an owned system

Three commands to a live system

What each of the three is
ChatGPT is OpenAI's closed hosted assistant. You rent access on its plans, it runs on OpenAI's cloud, and the plans run from a free tier to paid per-seat subscriptions, checked October 2026 (ChatGPT pricing). AnythingLLM is an open-source app from Mintplex Labs that runs on your own desktop or as a self-hosted Docker deployment, chats with your documents, and connects to local or cloud models.

Kortix is the open-source AI Operating System: your agents, their skills, your company memory, and every connector in one git repo you own, with the agents working on real cloud computers.
What you own in each layer
With ChatGPT, the model, the memory and the projects all sit inside OpenAI's product, and you keep access for as long as you pay. AnythingLLM keeps the documents and the index on your machine, which is a real step for privacy, and it still holds the agents and their settings inside the app. Kortix keeps the whole configuration as text in one git repo. Open source. Read it, fork it, audit it. Any model provider with your own keys. Or the ChatGPT plan you already pay for.
The difference shows when the AI does real work. Kortix runs one isolated sandbox per session. Each session has its own isolated machine and branch. Session work reaches main through a change request. Merge is default-deny for agents. Connector credentials are brokered server-side and never enter the machine.
Where a company moves next
A closed assistant is a per-person tool, and what a team teaches it stays with the vendor. A document-chat app keeps the knowledge and leaves the way the company works inside the app. A company that wants agents doing jobs across its tools, with permissions and an audit trail, needs the third layer. Per-resource permissions for people and agents. Roles, groups, and an audit trail. Run it on Kortix Cloud, in your VPC, or on your own on-prem network. Self-host is free.

Which one to pick
ChatGPT fits when you want a finished assistant and no setup to own. Choose AnythingLLM when you want document chat on your own machine without a cloud account. Kortix fits when the AI has to work across the company and the company has to own the agents, the data and the configuration.
AnythingLLM vs ChatGPT questions
The ownership questions a team asks before it picks.
Yes. Any model provider with your own keys. Or the ChatGPT plan you already pay for. Kortix connects the subscription you keep paying for alongside other providers.
It is close in shape. AnythingLLM runs document chat and agents on your own machine or a self-hosted Docker deployment, and it can use local or cloud models. It stays a document-chat app, so the agents and their settings live inside it.
ChatGPT keeps your data in OpenAI's cloud. AnythingLLM keeps the documents and the index on your own machine or server. Kortix keeps the configuration in a git repo you own and can run on your own infrastructure. The AnythingLLM data privacy page covers the detail.
It adds the parts a team needs to run agents together: per-resource permissions for people and agents, roles, groups, and an audit trail, with each session on an isolated machine and work landing through a change request.
