0N — the inbox that takes your side

Not a mock-up. A still of the live demo office, taken from the real app after every release. The glass lifts when you tap it.

TRY IT ON THIS PAGE

In 0N every email obeys the reader, not the sender. This page obeys you the same way. Pick, and watch the letter and the whole page follow.

PEOPLE v. YOUR INBOX

Exhibits from a real week of office email. Each one animates its crime, then its sentence. Tap any exhibit to flip it yourself.

EXHIBIT A — THE COMIC SANS COUNTER-OFFERAS SENT

We are prepared to offer a refund of $40. As stated previously, nobody reads cakes. Govern yourself accordingly!! 😊

We are prepared to offer a refund of $40. As stated previously, nobody reads cakes. Govern yourself accordingly.

Their font never enters the building. The email arrives in their words — it opens in yours. You'll simply never know it was Comic Sans, and you'll be happier.

EXHIBIT B — THE UNBROKEN LINEAS SENT

PLEASE BE ADVISED THAT PURSUANT TO SECTION 12(b) OF THE AFOREMENTIONED AGREEMENT THE UNDERSIGNED HEREBY GIVES NOTICE WITHOUT WAIVER OF ANY RIGHTS REMEDIES OR OBJECTIONS PREVIOUSLY RESERVED AND FURTHERMORE

PLEASE BE ADVISED THAT PURSUANT TO SECTION 12(b) OF THE AFOREMENTIONED AGREEMENT the undersigned hereby gives notice…
⟨ narrower · remembered for this sender ⟩

One tap, and it wraps forever. 0N remembers that this sender writes in one enormous line — and quietly fixes every email they will ever send you.

EXHIBIT C — THE BILLBOARDAS SENT

…the actual message is down here somewhere. It's two sentences.

Counsel — confirming receipt of the revised worksheet. We will respond by Thursday.

Just the words. Banners fold away, tracking pixels starve, and printing is text-only by default — opposing counsel's logo can buy its own ink.

EXHIBIT D — THE MICROSCOPICAS SENT

The parties agree that all notices shall be delivered in writing and shall be deemed received upon the earlier of actual receipt or three days after mailing, whichever occurs first, provided however that any notice delivered by electronic mail shall be deemed received upon transmission absent a bounce, and further provided that the foregoing shall not limit any right to object on grounds of legibility, which right the drafter has thoughtfully made impossible to exercise by rendering this clause in a font size customarily reserved for the bottom row of an eye chart.

You read at 21px. Or 42. Your call, every email, automatically.

The lean-in squint is not a core exercise. Every person in the office sets their own size, font, and spacing once — and every email obeys.

EXHIBIT E — RE: RE: RE: RE:AS SENT

confirmed. reporter as before.

Threads read as a conversation. Their side left, your side right, newest at the bottom — and the untouched original is always one tap away. We never change the email. Only how it treats you.

EXHIBIT F — THE SUBJECT THAT WAS THE WHOLE LINKAS SENT

(no body. one picture. the subject is the address bar.)

🔗 my.uscis.gov …iUfilename (a link, as the subject)🖼 1 picture — fits the screen

tap the link line for all 112 characters, if you ever want them

Someone will paste the whole link into the subject. 0N shows the part a human can read, keeps the rest one tap away, and makes the picture that came with it fit your screen instead of your scroll finger.

AND THEN — THE PART NO EMAIL APP HAS

Ten people, one Gmail, and the only question an office inbox was ever asked — "who's on it?" — answered at a glance, all day. Nobody forwards the office its own mail. The boss never has to ask.

EVERY COMPLAINT, ANSWERED

Twenty years of "why can't email just…", in the words people actually say, and what 0N does about each one. Only things that are live in the demo office today. Nothing here is a roadmap.

①READING

The sender picked 9pt grey on white and I'm squinting.: Every person sets their size, font, spacing and colour once. Every email obeys, automatically. The sender chose the words; the rest is yours.
Tracking pixels. Remote logos. Billboards.: Remote pictures are held back by default. A banner says how many and from whom. One tap shows them, or always from that sender, your rule.
In a clean reader I can't tell who it's from.: The sender's logo and brand colour sit atop the 0N letter, fetched once by our server, never by your browser.
Twelve levels of > > > quoted history.: The quoted history folds. An open email shows the last message and one line: expand thread.
Where is the original?: "Show original" on every email and every bubble. Raw if plain, framed if HTML. WE NEVER CHANGE THE EMAIL.
They pasted the whole link as the subject.: It reads as a short link. The whole thing, all 112 characters, on a tap.
Bold and colour the sender put in are gone. Or the mail is a mess.: The sender's formatting survives in the clean reader, with TIDY one tap away to strip it.
I need this in English.: 🌐 on the email. Spanish, Hebrew, Russian, Turkish, anything, into the office's language, by the office's own AI. The original stays one tap away.
Date, no year, no time.: Every message carries its weekday, date and time. On the phone, every bubble is stamped.

②THE INBOX

Gmail hides my mail in tabs and "Important".: One list, newest first, nothing hidden by a robot. Categories are yours, and visible.
Who opened this? Did anyone answer?: Every row wears its state. Nobody's seen it. OPENED · JAN. RESPONSE NEEDED. ✓ CALLED BACK. ✓ FILED. ✓ PAID. REPLIED CAN'T BE CLICKED. IT IS EARNED.
Six emails from the same guy in an hour.: The burst row: one line, "6 from them · 2 files". Unfold, done-all, download-all, one reply.
A thread is fourteen rows.: One row per thread with a ⛓ chip. The newest speaks for it.
I can't sort my inbox.: By person, by thread, by day, by sender. Day headers in Sent.
Same sender, same folder, every single time.: The ∞ rule files every future email from them on arrival. Tags become Gmail labels, so Gmail shows the same filing.
Unread is a bold line I keep missing.: An envelope in your accent colour. Or a dot. Your pick.
I keep pressing the star and it changes colour.: Every star and bang Gmail has, same colours, synced both ways.
Take me back to the email I was just on.: ↩ beside INBOX walks back through the emails you opened.
Did it arrive?: The knock. A sound, and a banner with FROM, subject and tags. The tab title counts the unread.

③WRITING

Reply-all accidents.: Reply-all is the default on multi-party threads, outside domains are tinted on the chips, and the reply announces itself: "↩ all 4 · just the sender".
My attachment became a Drive link.: Real attachments, in and out, 15 MB each, shown as boxes at the bottom like normal mail, with a 📎 jump at the top.
Our signature is a mess on phones.: The office signature comes straight from Gmail, rich or plain, under every outgoing mail.
Two of us answered the same client.: Live presence. "Feb is drafting a reply to this right now."
A junior sent it before anyone read it.: 👀 FOR REVIEW on any reply or letter. The team is pinged. The ping opens the draft.
Forward is where?: On the open email, attachments included.
The reply box covers my phone.: It lives behind a grip. Tap to raise, swipe to fold. An AI draft raises it for you.

④THE OFFICE

Who's on it?: Assign an email to a person. They're pinged. You're pinged back when it's done. The boss never has to ask.
Break this into tasks.: Type the task, tap the teammate's face. Select five emails, type "print", tap a face: one task whose checklist is the emails.
What's on my plate?: 🎯 The emails on you, your tasks, the office items. One panel, gold badge.
We forward the office its own mail.: Drop emails into the office chat as links with your comment. "Thoughts on this guy?" Nobody forwards.
Ten logins, ten licenses.: One Gmail, ten PINs. Everyone has their own name, prefs, plate and pings. NO PER-SEAT TAX.
Remember AIM? A room, a buddy list, a door sound.: That's the office in 0N. One room, voice notes, real file drops, who's in, the knock when mail lands. It becomes 🚰 the Watercooler when the inbox is clear. You earn it.
Where's the client's file?: 👤 Every email, every file, every date, owed and collected, a note. Assembled from what's already there. No data entry.
Print it like a lawyer.: Text only by default. Or the print pack: pictures and page one of each PDF. A print station that prints on arrival.

⑤THE PHONE

The mobile app is the lesser version.: The same office. Categories, actions, stars, chat, printing, the AI, your prefs. Full-featured, or better.
Buttons with no names.: Press and hold any button and it says its name before you use it.
Where's the AI on my phone?: The ✨ grip on the left edge. Tap it, or slide it right.
Is there an app?: Add to home screen. It installs from the browser. No store, no update nag.

⑥YOUR AI

Which AI reads our mail?: Yours. Claude, GPT or Gemini on the office's own key. 0N never marks it up and is never the middleman. OFF BY DEFAULT.
Summarise my morning.: The brief: a full read of the last day or two, at the thoroughness you pick.
Draft the reply.: It lands as a draft, into the review loop. A robot never sends.
What's the date in this scanned notice?: Drag the PDF in, ask, add it to the calendar.
Names, numbers, dates, not prose.: The call sheet. The AI fills fields.

Every person also sets their own font (legal, dyslexic-friendly, large caps…), size, boldness, spacing, theme, accent, unread mark, attachment position, dividers, translate language, sort, pictures policy per sender. It follows your PIN to any machine in the office.
