Is this a Gmail extension?

No. Airbox works entirely through email forwarding, so there's nothing to install and nothing reading your whole mailbox. You forward what you choose, or set a Gmail filter to do it automatically.

How is this different from Gemini in Gmail?

Gemini in Gmail locks you to Google's model inside Google's UI. Airbox is bring-your-own-AI — use Claude, ChatGPT, Google Gemini, or others — and works by forwarding, so it fits any inbox. See the Gemini-in-Gmail comparison for details.

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.

Add AI to Gmail

The short answer

To add AI to Gmail, get a private Airbox address, connect your own AI provider key, and forward mail to it — or set a Gmail filter that auto-forwards matching messages. Airbox summarizes, drafts, translates, or triages each email and sends the result back into Gmail. No browser extension, no account switch, and you use your own AI model.

How to connect AI to Gmail

Create a free Airbox address and connect your AI provider key (Claude, ChatGPT, Google Gemini, and more).
Forward any email to your Airbox address, or in Gmail go to Settings → Filters → Create filter and add a “Forward to” action pointing at your Airbox address.
Add a short instruction on the subject or first line; the AI's reply comes back into your Gmail inbox.

Example

Subject: Fwd: Long client thread

(* @gemini summarize and list what needs a reply *)

---------- Forwarded message ----------
...the email you forwarded...

Gmail forwarding addresses need a one-time confirmation — Airbox surfaces the confirmation email so you can approve it.

What you can do from Gmail

Summarize long threads and newsletters
Draft replies in your voice, ready to send
Auto-forward whole labels (newsletters, receipts) through AI
Translate, extract tasks, or triage incoming mail
