# Private AI assistants

AI assistants compared on training on your data, local processing, chat retention and accounts, with evidence.

These AI assistants do not use your prompts and files to train models by default, or run entirely on your own device. Compare chat retention and account requirements on each rating.

## Does ChatGPT train on my chats?

See the ChatGPT rating for its current data controls and retention, with links to OpenAI's own documentation.

## Can I run an AI assistant locally?

Yes. Local tools download open models and run them on your computer, so prompts never leave it.
