The email agent built around decisions,
not busywork. Dirac is not just an inbox. It's a product made with a belief that founders shouldn't be their own email assistants. Dirac lets you know what's important for the day, and the AI sorts out everything in the background.

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

Social proof
Trusted by founders who live in their inbox.
“There's no shortage of email tools out there. I stick with Dirac because of trust. My inbox is personal. If someone starts shuffling things around and I can't find stuff, that's worse than the mess I started with. Before this I would've just kept doing it all myself.”
Silvia Jiang

“I love Dirac's take that email shouldn't be the founder's job. I get a morning brief, tap send on what looks right, and I'm out. That's the whole thing. No inbox first thing, no triage spiral \[before\] coffee.”
Artin Amraei
Builder | Agency Owner at Nerodyn
“I used Superhuman for two years. Fast inbox, still my problem every morning. Gmail organizes what arrives. Dirac handles it before I wake up. Not a faster inbox, a smaller one. I switched and haven't looked back.”

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
Dirac handles it overnight. You start as a decision-maker, not an operator.
AI that does the work
Superhuman makes you faster at triage. Dirac triages overnight for you. You review and send — from scratch.
Always on, fraction of the cost
Dirac runs 24/7 for $20/month and learns your voice in one click.
Your voice, your approval
Nothing sends without your tap. Dirac drafts in your tone from your sent mail — private to you, no autopilot.
Morning brief
Open one summary — what matters, what's handled, what needs yes or no. No scrolling through threads to figure out your day.
Works where you already are
Connect Gmail in minutes. No new inbox to learn — Dirac sits behind the email you use.
Learns how you write
Dirac reads your sent mail to match your tone. Drafts sound like you, not a generic assistant.
Private by default
Your mail stays yours. We don't sell data or train public models on your inbox — nothing sends without your approval.
