How long a thread can Airbox handle?

Long ones — Airbox uses lossless compression and folds the full thread into the request to your model, so the limit is effectively your provider's context window. For very large threads, ask for a structured summary so the key points stay front and center.

Will it summarize attachments in the thread too?

Yes. Text and PDF attachments are extracted and included as content, and images are passed to a vision-capable model, so the summary can cover what's attached, not just the message body.

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.

Is it safe to point Airbox at my real email?

Yes — that's exactly what Airbox is designed for. Airbox only acts on mail from senders you allow, and it only treats the subject and first body line (or a (* … *) block) as instructions. Everything else in a forwarded email is quarantined as untrusted content and never obeyed for your own security and privacy. Your API keys stay fully encrypted.

Summarize long email threads with AI

The short answer

To summarize a long email thread with AI, forward the whole thread to your private Airbox address. Airbox sends it to your own AI model and emails back a tight summary — the decisions made, who owns what, deadlines, and the open questions — usually within seconds. No copy-paste into a chatbot, no app to open

Workflow options

Forward the thread to your Airbox address. Add an instruction like “summarize and list every decision and deadline,” or send it bare for a default summary plus action items.

How to do it

Get a free Airbox address and connect your AI provider key (Claude, ChatGPT, Google Gemini, and more)
Forward the thread to that address
Put your ask on the subject or first line — or leave it blank for the default summary + action items — and send

Example

Forward the thread and put the instruction on the trusted first line:

Subject: Fwd: Q3 launch thread (47 messages)

(* @claude summarize the decisions, owners, and deadlines; list open questions *)

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

Everything below the instruction is treated as content to read, never as a command.

Good asks for a thread

“Summarize and list every decision and deadline.”
“Who owns what after this thread? Bullet the action items.”
“Catch me up — I was out for a week. What changed and what needs me?”
“Draft a reply that confirms the next steps.”
