Nexus · invite-only preview

DecimaWorks

Your mail already knows what you owe, what you run and who you work with. Nexus writes it down.

Nexus is a desktop app that reads your own Gmail and builds a private knowledge layer on your computer: your Projects, your Commitments and your Network. Every morning it tells you what needs you.

What Nexus does

Three things your inbox never shows you

Mail is where work is agreed and then forgotten. Nexus reads each thread once, records what it says about your work, and keeps that record current as new mail arrives.

  • Projects

    The programs of work in your mail, each on one page: what it is, who is on it, what has been decided and what is still open. Nexus proposes them; you confirm, rename or fold them.

  • Commitments

    What you promised, what others promised you, and when it falls due. Each one links to the mail it came from, so you can check it in one click.

  • Network

    Every person you correspond with, what you work on together, and when you last spoke.

  • The daily briefing

    Once a day Nexus reads new mail and writes a short briefing: the commitments due, the asks waiting on you, the projects that moved.

  • Review

    When Nexus is unsure who promised what, it asks you. Your answer is recorded and the pages update.

  • Agent access

    Optional and off by default: let an AI tool on your own computer read your knowledge layer over a local connection, so it knows your work as well as you do.

Your Gmail

What Nexus does with your Gmail

Nexus asks Google for one mail permission, read-only (gmail.readonly), and for the sign-in permissions that give it your name, email address and account ID. Here is exactly what it does with them.

  • What it readsThe sender, recipients, subject, date and plain-text body of each message in your Inbox, Sent mail and Trash. Newsletter headers, so it can tell a notice from a conversation.
  • What it skipsSpam, Drafts, and mail Gmail sorts into Promotions and Social. Attachments are never downloaded.
  • WhyTo find the projects, commitments and people in your mail and write them down for you. A commitment lives in a sentence in the body, so Nexus needs the body, and a message’s metadata alone would leave every page empty.
  • What it never doesSend, delete, archive, label or change any mail. The permission it holds does not allow it.
  • Where it is storedEverything Nexus builds is stored on your computer.
  • How to stopWithdraw Nexus’s access at any time at myaccount.google.com/permissions. Nexus stops reading new mail at once.

How it works

One program on your computer

Nexus is a single desktop application with the knowledge engine inside it. Everything Nexus builds is stored on your computer.

  • 1. Sign in with Google

    One Google consent covers sign-in and the read-only Gmail permission. Your Google tokens are held encrypted in our cloud, so no secret has to live on your machine.

  • 2. Nexus reads your last week

    The first build reads seven days of mail and writes your first pages. It takes a few minutes and you watch it happen.

  • 3. It keeps up

    Google tells Nexus when new mail arrives. Nexus reads it, updates your pages and, once a day, writes your briefing.
