Re: studio lease — final numbers

Hi — great, those terms work for us. I’ve attached the signed addendum so we’re all set for the 1st.

One small thing: could we keep the loading-dock access on weekends? It’d make the move-in a lot smoother.

Thanks for being so easy to work with on this.

What makes it good

Everything you want. Nothing you don’t.

Built on battle-tested foundations, wrapped in an interface that respects your attention.

Search that actually finds it

A full-text index over every message — 50,000+ mails return instantly. Speak its language: from:*school.org, is:unread, has:attachment — filters become chips as you type, with live counts. Save any search as a Nest and it lives in your sidebar like a mailbox.

A reader that tames ugly mail

Every message is re-typeset into clean, readable text — no blinding HTML, no jarring fonts. Remote images and trackers are blocked until you say so. Marketing mail finally reads like a letter.

Compose without the chaos

A calm, constrained editor in the spirit of Notion and Obsidian. Bold, lists, quotes, code, links — and markdown shortcuts that just work. No font menus, no color pickers, no junk in the wire.

All your accounts, grouped

Bring every inbox together and organize them into groups that match your life — Personal, Work, Side projects — each with its own icon and color. A true Postbox replacement for people who run more than one address.

Bring your own AI (or not!)

Point it at your own local model and it catches phishing, scams, and spam the old filters miss — running entirely on your hardware, with nothing about your mail ever sent to a cloud. Don’t want AI? Leave it off; everything else works exactly the same.

Instant, even at 50k messages

Native AppKit lists, optimistic actions, and an architecture tuned for huge mailboxes mean no spinners and no stutter. Archive, flag, and triage at the speed of thought — with multi-level undo.

Why it’s different

Opinionated on purpose.

A few principles we won’t compromise on.
