Fair questions.

A chatbot lives in a browser tab and tells you how to do the thing. Lyndran is an app on your own computer that does it — you hand it your folders, your mail, your tabs or your screen, and it hands back the finished thing instead of instructions: the three contracts tabled, the invoice out of March’s mail and into a folder, the twelve orders filled in and waiting for your press. It asks before it changes anything, and every change undoes in one press. And unlike a chat, an answer that works is kept as a tool you can run again for free.

They are real, and if what you want is a folder rearranged, several will do it. Two things decide whether this is the one you want. The first is reach: Lyndran does the task inside the things you already use — your mail, your Finder, the browser you are signed into — so “find the invoice they sent in March and file it” is one task, not a file operation with the rest still left to you. The second is the press: confirming a deletion is a dialog somebody added, and this is the other thing — the ability to commit is not in the app, so there is nothing to switch off or forget. And one thing we are plainly not: this is not for writing software. No terminal, no code, no repository. It is for the invoice, the supplier and the claim.

Right now, yes — nothing is charged. Bring your own model provider key and Lyndran is free in the plain sense: your Mac talks to the provider directly, you pay them for the thinking, and you pay us nothing. Memberships, where we handle the key and meter the carrots for you, will open later; we’ll publish the prices before they apply and we’re not promising a date we don’t have. Nobody gets moved onto a paid plan quietly.

No — but this page used to say something stronger than we can say now, so here is the exact shape of it. An email is written for you and put in front of you whole: every recipient, the subject, the entire body. You press send on that card. Lyndran presses the mail app’s own Send button afterwards, so you are not sent off to find it — your press is the approval, and without it nothing goes. There is no bcc field anywhere in the code, five recipients is the most a card can carry, and “always allow” is never offered for sending, because a sent email cannot be recalled. One more thing sends in your name, and only when you ask for it: an out-of-office. The card shows the Gmail account, the days and the exact reply, and after you press it, Gmail sends that reply to everyone who emails you until the last day, or until you ask Lyndran to turn it off. Replies it has sent cannot be recalled either. Nothing is deleted for good either: what it clears goes to the Trash, and every change it makes has a one-press undo. Say no and nothing happens at all.

It is being built now, and there is no date we would stand behind yet. The parts that live in your browser and in your own files already work there — reading a page, filling one in, finding and renaming and tidying your own files. The parts that reach into Mail, Messages, Music and the Finder are Mac things, and they have no Windows twin; on Windows it also cannot click inside other applications the way it can on a Mac. Leave your address on this page and you will hear the day it lands.

Your files stay on your own computer, and everything Lyndran keeps — tools, history, preferences — lives there too, inside a boundary you can open in Finder — six folders to start with, plus any you add yourself in Settings, one at a time. When a task needs fresh thinking, the relevant slice of context goes to the model for that thought and comes back; nothing about you is stored off your machine. And “forget everything about me” is one press away.
