Dirac · Writing · Productivity
Dirac is an AI email assistant that reads your inbox overnight and shows up with a morning brief before your first meeting. It handles inbox management by sorting mail into what actually needs a decision, summarizes long threads, and produces AI email drafts in your own writing voice. Nothing leaves your outbox without your approval, which is the whole point for founders who clear their queue daily and still feel buried.
About Dirac
What Is Dirac
Dirac is an AI-native email client built around decisions, not busywork. You connect a Gmail or Outlook account, and the Dirac email agent spends the night reading your inbox, running email triage on every thread, and preparing a short brief for the morning. Instead of another set of filters and labels, you get a list of what needs you and a stack of replies already written.
The pitch is narrow on purpose. Founders and small teams don't need a faster way to move mail around. They need something that tells them which three messages matter today and handles the rest, and that's a different problem than the one most email apps solve. So what makes Dirac different? It studies your sent mail to learn how you write, so the drafts sound like you rather than like a chatbot.
There are limits worth knowing up front. Dirac is a web app for Gmail and Outlook; it isn't a standalone mail server, and there's no mobile app listed yet. Access currently runs through a waitlist, so early access rolls out over time and you might wait before you can use it.
Getting Started
- Join the waitlist on the Dirac site and wait for your early access invite.
- Connect your inbox with OAuth for Gmail or Outlook. No passwords are stored, and you approve the access Dirac gets.
- Let Dirac read your sent mail privately so it can learn your tone, vocabulary, and how you close loops.
- Wake up to your morning brief, review the priorities and ready-to-send drafts, then approve what you want to send.
- Adjust drafts or ignore them. Nothing sends on its own.

Key features
Overnight Inbox Reading
Dirac reads your inbox while you sleep and prepares a morning brief by the time you sit down. It pulls out what needs a decision rather than just what arrived, so you open the day with a short list instead of a full queue.
Priority Triage by Consequence
Every plan includes priority triage that ranks threads by how much they matter. Labels and filters can help you move faster, but Dirac's job is telling you which messages actually need you and which can wait.
AI Drafts in Your Voice
The agent studies your sent mail privately, learning tone, vocabulary, and how you close loops. Drafts come back sounding like you wrote them, which cuts the editing time on routine replies to almost nothing.
Morning Brief
Your brief shows priorities, thread summaries, and ready-to-send replies in one place. It's designed to land before your first meeting, so you can decide what to approve in a few minutes rather than an hour.
Approval-First Sending
Nothing sends without you. Dirac prepares the work, but every message waits for your approval, which keeps a human in charge of anything that leaves the outbox.
Gmail and Outlook Support
Dirac connects through OAuth to Gmail and Outlook, the two inboxes most founders live in. As a Gmail email agent it never stores your password, and it starts reading only with the access you approve.
Pros and cons
Pros
- Prepares overnight work so your morning starts with a brief, not a backlog.
- Drafts replies in your own voice by learning from your sent mail.
- Triage ranks threads by consequence, not just recency.
- Approve-before-send keeps you in control of everything that goes out.
- Works with Gmail and Outlook through OAuth, with no passwords stored.
Cons
- No free plan. You get a 7-day trial with no credit card, then it's $20 a month or $200 a year.
- Access is waitlisted, so early access may take time before you can use it.
- Only Gmail and Outlook are supported, so other providers are out of luck.
- No mobile app is listed, which means no brief on your phone yet.
