Questions

AI assistant: common questions

Does it cost extra?

No. The assistant is part of every plan. If you use a cloud model, that provider bills you for it as usual; Apple Intelligence and local models cost nothing.

Can I use my ChatGPT subscription?

Yes. Sign in with ChatGPT in Settings › AI and the assistant uses your plan, no API key needed.

Is my mail used to train models?

bytemail sends only the text needed for the task, straight to the provider you picked, under that provider's terms. Choose Apple Intelligence or a local model and nothing leaves your Mac.
