Ask your mail a question. Watch it search. Check its sources.

You remember the email. Something about the deck quote, from a contractor, around May. You could search "deck" and read twenty threads. Or you could ask.

Ask Zero takes the question, decides what to search for, runs the searches through every account you've connected, reads what comes back, and answers. The part we care most about is that it shows every step and cites every email it read.

Ask the way you think

"Did I ever reply to the landlord about the lease?" "Pull every invoice from Q2." "Which account is my Figma login on?"

Zero turns each into one or more provider searches: from: a sender, subject: a word, newer_than: a range. You watch it choose them, and if it searched for the wrong thing you know at once.

A question fans out to every mailbox you've connected, each searched with that mailbox's own credentials through the provider's own search. The results come back as one answer.

Watch it work

While Zero works, the steps appear in order. Searched inbox with the query it chose. Read email with the subject. Read attachment with the filename.

Under the answer sit the emails it read, as cards showing sender and subject. Tap one and you're in the thread.

That citation is the load-bearing part. A language model summarising your mail can be confidently wrong. A citation lets you check in one click.

Live, not mirrored

Zero searches your providers directly, so there's no date window. A thread from three years ago is as reachable as one from this morning, as long as the provider's search can find it.

The trade is that it searches by keyword. If the message says "rear timber decking" and you ask about "the deck", Zero has to guess the words, and sometimes it guesses wrong. The Searched inbox steps tell you when.

The app's search box works the other way round. Its instant tier covers the last six months of mirrored mail with a keyword pass and a semantic pass that matches meaning. Switch it to All mail and it goes live, like Zero does.

Where it stops

It can search, read a message, read an attachment's text, and draft. Ask it to reply and it writes the reply in the conversation, ready to take into a compose window from whichever mailbox the thread lives in.

It can't send. It can't archive, label, trash or forward.

A conversational assistant is exactly where "just do it for me" is tempting. Reading a draft takes two seconds. Recovering from a sent email takes a phone call.

Where it's weak

Keyword guessing, above. Attachments are shallower than bodies: text in a PDF, Word file or CSV is read on request, while a scanned image or an .xlsx spreadsheet isn't.

And the answer inherits the model's mistakes. Follow the citations on anything that matters.
