Dropstone for everyone

The agent that acts in the real world on your behalf, and knows the one moment to ask.

Dropstone started in the terminal. Developers have used the Dropstone CLI to hand an agent real work and watch it get done. Today we are bringing that agent to everyone, at chat.dropstone.io.

The general version of Dropstone lives alongside your inbox, your calendar, and your contacts, and acts in the real world on your behalf. It reads what comes in, decides what actually needs you, drafts what it can, and waits at the one line a careful assistant would wait at. Nothing irreversible happens without your yes.

We built it on a belief we set out in our research, Project Yaazh: for an agent you let into your real life, knowing when to stop matters more than knowing how to act. This is that agent, now in your hands.

What you can do with it

Email that drafts itself, and waits. Dropstone reads your inbox, sorts what matters from what does not, and prepares replies in your voice. The drafts sit ready. Nothing sends until you say so.

A calendar that organizes around your real work. It reads the commitments forming in your mail, holds your focus time, sequences your day, and surfaces a conflict before it becomes a missed meeting.

Calls and bookings made for you. Ask Dropstone to book the table or check availability, and it makes the call, handles the back and forth, and brings the decision back to you when the choice is yours to make.

The urgent things, brought to you. When something cannot wait and needs your words, Dropstone reaches you, takes what you tell it, and turns it into action you approve.

A few built-in tools

Dropstone comes with the tools an assistant actually needs, working together as one agent rather than a drawer of separate apps:

Email: read, triage, draft, send on approval.

Calendar: organize, schedule, resolve conflicts.

Contacts: find the right person, confirm before reaching them.

Calls: make and take calls on your behalf. In beta for Max, in select regions to start.

Web research: look things up, and report back when you are away.

More tools are on the way. They will arrive the same way these did, only after they can be trusted with the access they need.

How it works

Dropstone is a resident agent. It does not wait for you to open it. It runs continuously on our servers, watching for what needs doing while you are asleep or away, and reaching back to you when a moment is yours to decide.

It is powered by the Dropstone model family, Fast, Pro, and Heavy, choosing the right one for each step and leaning on Heavy, our most capable model, for the hardest reasoning. It acts through real channels rather than a chat box. The core of it is a single rule: Dropstone can read, think, draft, and dial, but it cannot send, book, spend, or commit without your explicit yes. That gate is not a setting. It is the foundation everything else is built on.

Built to be trusted

An agent that lives on servers and can act in the world is exactly the kind of thing that deserves caution, so we built the restraint first.

The gate. Nothing consequential happens without your approval. Drafts wait. Bookings are held, not confirmed. People are identified, but not contacted until you nod.

Staged access. Power arrives in rings. Reading and organizing first, drafting next, acting on approval after that, and live calls last, the highest-stakes ring.

Transparency. Every call announces itself as an AI. Every action leaves an audit trail. Everything is reversible, and there is always a hard stop.

We stress-tested this before shipping it. In Project Yaazh, across 139 adversarial attempts, on-the-spot pressure, forged authorizations, and instructions hidden inside incoming mail, none produced an unapproved action. That is the bar, and it is the one we keep testing against.

Availability

The general version of Dropstone is live today at chat.dropstone.io , on the Pro and Max plans. Email, calendar, contacts, and web research are open now, in beta.

Phone calling is in beta for Max users, in select regions to start, the places where we can meet the calling rules before we widen.

Actions that touch the most sensitive parts of your account sit behind additional security layers we are still completing, and will reach Max users once that work is finished and tested.

Developers can keep using the Dropstone CLI, the same agent, in the terminal.

Plans and pricing are at dropstone.io.

What's next

For a long time, the assistant people imagined was never a smarter chatbot. It was something that would simply handle things, and check with you when it counted. That is what we are building, and today it opens to everyone. Dropstone does the real-world work, and it waits for your hand.
