An offline alternative to ChatGPT

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

When you set Twoody up, it downloads once a model sized for your computer, 2.8 or 5.8 GB. From then on, conversations, documents and voice messages are handled on the computer: turn Wi-Fi off and it keeps answering. Only web search, off by default, and the conversations you keep on your optional account need the internet.

Private, too

What never goes out cannot leak: without an account, or in a private conversation, your conversations and documents stay on your computer. The few things that do go out — the update check, the model downloads, diagnostics without content during the beta (which can be turned off), web search if you turn it on, the conversations you keep on your optional account, encrypted end to end — are listed, with how to check them.

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.
