Dirac

The third major feature is By Instruction, which lets founders manage their inbox using plain English commands. Instead of learning complex filters or rules, users simply tell Dirac what they want: 'star anything from investors this week' or 'archive newsletters from last month.' Dirac finds the relevant threads, displays them for review, and waits for a single tap to apply the action. This capability extends to batch operations—like filing all promotional emails or marking certain senders as priority. Additionally, Dirac integrates directly with Gmail, requiring no new inbox to learn; it sits behind the email the founder already uses. The AI runs 24/7 at a fraction of the cost of a human assistant ($20/month) and works continuously, even during weekends and late nights when deals might close. This combination of natural language control and continuous operation makes Dirac uniquely accessible.

Dirac's overall approach is to turn email from a daily burden into an overnight operation. The workflow begins when the user connects their Gmail account, which takes under ten minutes. Each night, Dirac's AI scans every incoming message, categorizes them by relevance—deals, investors, customers versus newsletters, notifications, and spam. It then generates the Morning Brief, a curated summary that highlights threads needing action, along with ready-to-send drafts written in the user's voice. In the morning, the founder opens the brief, reviews the handful of items that require personal judgment, taps send or provides edits, and is done within minutes. Dirac never sends anything without approval; every draft must be explicitly authorized. This methodology eliminates the reactive triage loop and replaces it with a proactive decision-making session, effectively shrinking the inbox to only what matters.

Concrete use cases illustrate Dirac's impact. A founder closing a funding round can instruct Dirac to 'flag any email from investors or legal counsel' and receive a morning brief with term sheet follow-ups and signature requests. A product manager dealing with a critical bug can have Dirac prioritize all engineering threads and draft status updates for stakeholders. A busy agency owner can archive newsletters automatically, respond to client emails in their own voice, and never miss a project deadline. The outcomes are consistent: founders reclaim 10+ hours weekly, start their day with clarity, and never worry about missing an important message. For example, one user reported that after switching from Superhuman, they no longer spend mornings triaging—Dirac handles it overnight, leaving a smaller, actionable inbox. Another noted that Dirac's voice learning made drafts feel personal, increasing response rates without extra effort.

Dirac is built for founders, entrepreneurs, and startup executives who live in their inbox and cannot afford to lose productive hours to email management. It works exclusively with Gmail accounts, integrating seamlessly without requiring a new email client. The pricing is $20 per month with a 7-day free trial, a fraction of the cost of a full-time assistant ($3,000+) or even Superhuman ($25/user/month). Dirac's target audience values trust and privacy—the company does not sell data or train public models on inbox content. The platform is always on, handling emails overnight and learning the user's voice from their sent mail. In summary, Dirac is not a faster inbox; it's a smaller one that lets founders start each day as decision-makers. The primary takeaway is that Dirac transforms email from a source of stress into a tool that works for you, silently and effectively.
