dirac - your intelligent email

4 min read Original article ↗

The problem

Your mornings shouldn't start in your inbox.
Same you, Completely different day.

Without Dirac

6:58am

Alarm goes off. You already dread opening email.

7:04am

47 unread. You don't know which three actually matter.

7:09am

Scan subject lines. Guess at urgency. Miss context.

7:22am

Reply to one thread. Two others slip.

7:41am

Still in inbox. Your first hour is gone.

8:15am

First meeting. You're reacting, not leading.

With Dirac

7:01am

Open your morning brief on your phone.

7:03am

Three things need your judgment. Everything else is handled.

7:06am

Review two drafts. Tap send.

The product

See what Dirac does while you sleep.

Your inbox is read, prioritized, and drafted before you open your laptop. You step in only where your judgment matters.

01What Matters

You only see what needs you.

Stop guessing which emails deserve your attention. Dirac surfaces the threads that actually need your judgment — deals, investors, customers — and handles the rest before you wake up.

02Voice Learning

Replies that sound like you wrote them.

No generic AI tone. Dirac learns how you actually write from your sent mail, then drafts replies you can send with one tap — calibrated to your voice, not a template.

GENERIC AI

Hi Roelof, I hope this email finds you well - wanted to confirm that we will be signing the documents by end of day. Additionally, I would be available for a call on Friday at 2pm. Please let me know if you have any questions. Yours sincerely, Avi

Roelof,
YES, will get the signed copy over before EOD. Friday 2pm works for me, I'll send a calendar invite.

Looking forward to it :),
Avi

03By Instruction

Manage your inbox in plain English.

Tell Dirac what you want: "star anything from investors," "archive newsletters from last month." It finds the threads, prepares the action, and waits for your one tap to apply.

Star anything from investors this week

FOUND 5 THREADS · WILL MARK AS STARRED

Social proof

I used to lose my first hour every morning to email. Now I open Dirac at 7am, send two drafts, and I'm in my first meeting actually prepared.

The morning brief alone is worth it. I know exactly what needs me before I've had coffee.

Investor replies used to take 20 minutes each. Dirac drafts them in my voice — I just review and send.

Founder, fintech

I stopped missing threads that matter. Dirac surfaces the ones I'd have buried under noise.

Why us

Built because founders shouldn't drown in email.

Most founders lose their first hours to triage, drafting, and follow-up — the same reactive loop, every morning. Dirac exists so your inbox is read, prioritized, and drafted before you open it.

Not a faster inbox

Gmail organizes what arrives. Superhuman helps you move through it faster. Dirac handles it before you wake up — you start as a decision-maker, not an operator.

AI that does the work

Superhuman makes you faster at triage. Dirac triages, drafts, and prepares replies overnight. You review and send — you don't write from scratch.

Always on, fraction of the cost

A full-time assistant costs $3,000+/month, works 9–5, and needs training. Dirac runs 24/7 for $20/month and learns your voice in under 10 minutes.

Your voice, your approval

Nothing sends without your tap. Dirac drafts in your tone from your sent mail — private to you, never sold, never sent on autopilot.
