Twoody
Offline AI
An offline alternative to ChatGPT
ChatGPT needs a connection: every question goes to OpenAI's servers. Twoody runs a language model on your computer, Mac, Windows or Linux — it keeps answering with Wi-Fi off, and your questions are answered there, not on a server.
Can ChatGPT work offline?
No. ChatGPT, its Mac app included, sends each question to OpenAI's servers and needs a connection. To use AI without internet, the model has to run on your own computer: that is what a local LLM is.
How Twoody works offline
On installation, Twoody downloads the model that suits your computer once: 3.5 or 6.7 GB. After that, conversations, documents and voice messages are processed on the computer: turn Wi-Fi off and it keeps answering. What goes through the internet stops while you are offline: web search, off at first, online connectors and the optional account.
Private, too
Your conversations and documents are processed on your computer, and a private conversation is kept there only. What goes out depending on what you turn on — such as the update check, the model downloads, web search if you turn it on, the conversations you keep on your optional account, encrypted end to end — is listed, with how to check it.
Where it helps
- On a plane or a train.
- On a closed or monitored network.
- With confidential files: clients, patients, contracts.
- Wherever the connection is poor.
What to expect
A model that runs on a personal computer is smaller than ChatGPT's: excellent for writing, summarizing and questions about your documents, less so for the hardest reasoning. Offline, it knows nothing that happened after its training.
Frequently asked questions
Is there an offline version of ChatGPT?
No: ChatGPT always runs on OpenAI's servers. An offline alternative runs a model on your own computer, as Twoody does on a Mac or on a Windows or Linux PC.
Does Twoody really work without internet?
Yes, once its model is installed: turn Wi-Fi off and it keeps answering, documents included. What goes through the internet, such as web search or the optional account, stops until the connection is back.
Which computer do I need?
A Mac with macOS 13.3 or later, a PC with Windows 10 or 11 (64-bit), or a PC with Linux (x86_64); an Apple Silicon Mac with 16 GB is comfortable. The calculator shows what each computer can run.
