Dirac is an AI email agent aimed at founders who spend the start of each day sorting messages. The company describes it as a product built around decisions rather than busywork, based on the belief that founders should not be their own email assistants. Rather than offering a faster inbox, it works behind the email account a person already uses.
Each morning, Dirac presents a brief covering what matters, what has been handled, and what needs a yes or no. It reads incoming mail, prioritizes it, and prepares draft replies written in the user's own voice. The user reviews the drafts and sends them with a tap. The company offers a 7-day free trial and a $20 per month plan.
Dirac connects to Gmail, and the site says this takes minutes. While the user is away, it reads the inbox, separates threads that need judgment, such as prospects, customers, investors and legal items, from routine mail like newsletters and notifications, which it files or archives. The user does not have to learn a new inbox.
In the morning, the user opens the brief and sees the few items that need a decision, along with drafts ready to send. Dirac learns tone from the user's sent mail, so replies are calibrated to the user's voice. Nothing is sent until the user taps approve, and the site states there is no autopilot.
The core feature is overnight triage, which surfaces the threads that need the user and handles the rest. This is paired with a morning brief that summarizes priorities in one view, so the user does not scroll through threads to plan the day. Voice learning drives the drafts, which the site contrasts with generic AI templates.
A third feature lets users manage the inbox by instruction in plain English. Examples on the site include starring anything from investors or archiving newsletters from last month. Dirac finds matching threads, prepares the action, and waits for one tap. The company also states that email data is not sold and public models are not trained on user inboxes.
