// autonomous inbox employee
InboxOS is an AI agent that manages your email around the clock. It classifies, drafts, and handles routine messages — in your voice, on your behalf. You only see what matters.
Start for free →// how it works
Link your Gmail or Outlook account in under two minutes. InboxOS immediately begins learning your communication patterns, your tone, and your priorities.
Every incoming email is analyzed in real time. InboxOS classifies by intent — inquiry, request, notification, cold outreach — and flags urgency based on context, not just keywords.
Routine replies are drafted in your voice, staged for review, and sent on your behalf once you've set your boundaries. You decide what gets auto-sent and what lands in your review queue.
Every morning you get a crisp briefing: what's been handled, what's waiting, what needs your attention. Your inbox becomes a curated to-do list, not a pile to dig through.
// the voice system
InboxOS doesn't write generically. It analyzes your sent history — word choice, sentence length, punctuation, tone — and applies it to every reply it drafts. After two weeks, clients stop being able to tell the difference.
Dear Sir/Madam,
I hope this email finds you well. I wanted to follow up on our previous correspondence regarding the proposal we sent last week. Please let me know if you have had a chance to review the materials.
Kind regards,
[Name]
Hey Marcus,
Checking in on the proposal — I know you're deep in Q3 planning. Happy to hop on a 15-min call if it helps move things forward.
Let me know.
[Your style, your phrasing, your tone]
// why we built this
"Inbox zero was always a lie. You clear a hundred emails and a hundred more arrive. The promise was never about the tools — it was about reclaiming time. But tools kept asking you to do the work. We decided to stop asking."
Email is the world's largest to-do list that no one organized. Professionals spend 11.7 hours a week on it. Generative AI has been capable of handling most of it since 2023. The only thing missing was an agent that would actually do it — autonomously, consistently, on your behalf.
InboxOS is that agent. It works while you sleep, thinks in your voice, and only interrupts you when it genuinely needs to.
// privacy
Your emails are used only to operate your agent. We don't use them to train any model, period. Your communication stays private.
Define auto-send rules by sender, topic, or intent. Set escalation thresholds. Whitelist VIPs who always reach you directly. You're never surprised.
Disable auto-send in one tap. Pause the agent entirely. Delete your conversation history. Revoke access at any time. Control is immediate and complete.
Enterprise-grade encryption in transit and at rest. Full audit logs on every agent action. Ready for compliance-heavy industries from day one.
InboxOS runs as a autonomous AI agent. Connect your email once, set your boundaries, and come back to an inbox that's already been handled.
