Do I need ChatGPT Plus?

No. Airbox connects through the OpenAI API with your own key, which is separate from a ChatGPT Plus chat subscription and billed per token.

Can I use a different model than GPT?

Yes. Airbox is bring-your-own-AI, so you can also use Claude, Gemini, and others — even route different Gmail labels to different models.

Do I have to forward each email by hand?

No. Forward or BCC manually when you want, or set an auto-forwarding rule in Gmail, Outlook, or Apple Mail so matching mail reaches your Airbox address automatically and runs through your AI with no extra steps.

How much does it cost?

Airbox has a free plan to get started. You bring your own AI provider API key, so you pay the provider directly for the tokens you use — there is no AI markup from Airbox.

ChatGPT for Gmail, without an extension

The short answer

To use ChatGPT in Gmail, you don't need a browser extension that reads your whole mailbox. Get a private Airbox address, connect your own OpenAI API key, and forward mail to it — or set a Gmail filter to auto-forward. Airbox sends the email to ChatGPT and the reply lands back in your Gmail inbox. You control which mail it sees and you use your own key.

How to use ChatGPT in Gmail

Create a free Airbox address and connect your OpenAI API key (from platform.openai.com, separate from ChatGPT Plus).
Forward an email to your Airbox address, or add a Gmail filter that forwards matching mail automatically.
Put your instruction on the subject or first line; ChatGPT's reply comes back into Gmail.
