The AI inbox that briefs founders every morning

Founders lose hours everyday to doing email, when they should be spending the time to build and make real progress. Dirac was made to end that. Dirac is an AI-native inbox that scans your threads, drafts replies in your voice, and shows a brief with only what needs your decision, quietly dealing with the 80% of un-important emails in the background. You run your inbox by deciding, not being your own assitant.

Hey Product Hunt!! 👋 I'm Peter, the Maker of Dirac.
On my last startup we were a tiny team with barely any traction. And I was still losing about a fifth of my working time to email. Cold outreach, notifications, prospects, internal threads. Volume wasn't the real issue.Everything funneled through me, and most of it didn't need me. But I had to read every message just to know which was which, or risk something important slipping through.
That's the part I kept coming back to. Founders aren't bad at email. They're stuck being their own assistant.
Every tool out there makes you faster at doing email. Superhuman, Hey, Gmail, all of them. But being faster at the wrong job is still the wrong job. Email pulls you out of building all day, and the best tools only make that a little more bearable.
🚀 🚀
So I built Dirac. An AI-native inbox where the AI does the busywork, not you.
Every morning it hands you a brief with only the emails that actually need you. Everything else gets sorted, filed, and handled in the background. Tell it to reply and it drafts in your voice. It already learned your tone from your sent mail. You show up to email already knowing what matters and what to say.
🎯
That's the difference. Every competitor is AI bolted onto a traditional inbox. Dirac is agentic. You make the calls, it does the work.
It's live at https://dirac.app if you want to try it. 14 days free, no card needed. But mostly I want to hear from you. What's the one email task you'd kill first? And what would you always keep for yourself?
I like the framing that founders shouldn’t just become faster at doing email. The real unlock is probably seeing only what actually needs a decision, and letting the rest move without constantly pulling you away from building.
Curious how Dirac decides what needs the founder’s attention and what can safely be handled in the background. Is that something users train manually over time, or does it learn mostly from inbox and sent email behavior?
Also, the “what would you always keep for yourself?” question is a good one. For me, anything related to partnerships, sensitive customer issues, or important founder-to-founder communication should probably stay human.

@andrasczeizel
Great questions, Andras!
This was actually something that I debated internally alot, cuz you wouldn't want any ai to just go off on their own, replying to stuff. Nobody trusts any tool with that, right?
So Dirac bg tasks follows 1 rule: reversability.
Think: archiving, starring, sorting, briefing you.
And one last thing - Definitely, human-to-human stuff is quite hard to get right, but Dirac (I believe) has hopefully nailed it 💅
I like the framing of “only what needs your decision.” Most inbox tools still assume you want to process everything, while in reality most emails are just noise
Dirac
@alex_j_jemmy Most email apps fall between “everything needs your decision” or “nothing needs your decision”. And both are unreliable.
I tried rlly hard to find the balance for Dirac. Glad someone noticed, Alex!
Dirac
@etiennegarcia Thanks for the question, Etienne.
Dirac reads your inbox and scans for context. EG. maybe 5 threads ago, your coworker mentioned his dog went to the vet on Tuesday 7pm. And when you wanna email him about booking a dinner, Dirac would know to avoid Tuesday.
And yes, it has a bunch of tonal ques that it uses for each seperate type of emails and changes tone automatically.
As someone who spends way too much of her morning triaging email instead of actually building, this hits close to home. The "drafts replies in your voice" part is what I'm most curious about. Does it actually learn your tone over time or is it more of a one-time setup?
Congrats on the launch, rooting for this one!
Dirac
@demi_tan Thanks Demi!
It's a one-time setup in the settings page, but every time you click "analyze" it can scan for your tone again.
So yes and no, hope this helps :)
@peterz_shu That's actually a smart design, manual re-analyze makes way more sense than trying to auto-detect tone changes. Gives you control without overcomplicating it. Makes me want to try it now lol
Dirac
@demi_tan Yeah I think this is max efficiency, minimum cost for both user and Dirac's operator (me).
(I don't want to have super high token costs of running auto-detect every few hours, anyways!)
A morning briefing from your inbox is such a useful idea for busy founders. Can you customize what the daily brief focuses on?
Dirac
@doganakbulut Dirac tries to be “smart” and see patterns by itself. But yes, you can tell it what you mostly want in the brief.
Eg. “Updates from work”, “sent by Sarah”, “prospects replies”.
#9 and 82 points on launch day — how'd you pull that off straight out of the gate? Pre-warmed audience, community seeding, a strong hunter? Genuinely trying to learn what a clean PH launch takes these days.
