Dirac

About Dirac

Dirac is an AI-native inbox built for founders who want to reduce time spent on email triage. It scans incoming messages, drafts replies in the user's voice, and presents a morning brief containing only threads that require a decision. Unimportant emails are sorted, archived, or starred in the background without manual intervention.

Review

Dirac approaches email management differently from tools that simply speed up processing. Instead of showing every message, it filters out what the maker calls the "80% of un-important emails" and surfaces what needs attention. The system learns tone from sent mail via a one-time analysis, and background actions follow a reversibility rule-archiving, starring, sorting-so no irreversible automated replies are sent.

Key Features

• Morning brief that lists only emails requiring a decision, based on inbox scanning for topics and types like "needs reply" or "prospect may be interested."
• AI drafts replies in the user's voice after a manual tone analysis of sent mail; re-analysis can be triggered anytime from settings.
• Background handling of low-priority mail using reversible actions (archive, star, sort) without sending replies on the user's behalf.
• 14-day free trial with no credit card required.

Pricing and Value

Pricing details beyond a launch promotion of 50% off for two months are not yet defined. The free trial lasts 14 days and does not ask for a credit card. No subscription tiers or long-term costs have been published at this stage.

Pros

• Reduces inbox noise by hiding emails that don't need a decision, letting founders focus on building.
• Tone learning from sent mail helps draft replies that sound like the user, not generic AI text.
• Background actions are limited to reversible operations, which lowers the risk of AI making unwanted changes.
• Manual re-analysis of tone gives users control over when the voice model updates.
• Quick setup-connect an email account and the brief starts populating without lengthy configuration.

Cons

• Pricing after the promotional period is unknown, making long-term cost hard to evaluate.
• Currently only works with email; integrations with tools like Sentry, Linear, or Stripe are mentioned as future possibilities, not available now.
• Not well suited for people who prefer to see and process every email themselves, or who need detailed manual control over inbox organization.

Dirac fits founders who want a morning summary of decisions rather than a full inbox view and who are comfortable delegating sorting to an AI that only takes reversible steps. It's less appropriate for those who rely on external alerting sources or who want to inspect every message. The tool's emphasis on showing only what matters could appeal to small teams where the founder is the bottleneck for email triage.
