Personal assistance, from your Mac

Hand off the details.
Keep your day.

Why Rosi

Most chatbots answer.
Rosi keeps going.

Rosi can act across the services you already use, find current information, and carry context into tomorrow—so a conversation can become ongoing work.

01

A catalog of 1,000+ services.

Connect the services you already use—from Instagram, LinkedIn, Slack, and Notion to Google Drive, Docs, Supabase, Convex, and ClickUp. Ask naturally; Rosi can find a relevant capability and tell you when access is needed. Available actions and permissions vary by service.

Searches the live web

Rosi can pull the latest news, compare products, look up companies and people, check the weather, and crawl a website on demand to turn its pages into useful, source-backed data.

03

Builds continuity, not chat history

Journal with Rosi, maintain ledgers for workouts or any ongoing practice, save lasting memories, keep context across projects, and schedule work or daily briefs that use what came before.

04

Adapts to you. Grows with you.

Rosi learns your preferences, routines, and working style, so its help becomes more relevant over time. You can also create reusable skills for the way you work—and those skills remain fully owned by you.

Coming soon

Deep Research for the hard questions

Rosi will coordinate multiple research agents across parallel lines of inquiry, inspect the evidence, and return a clear synthesis for complex topics—not a shallow list of links.

A chatbot gives you a reply. Rosi gives you continuity, ownership, and follow-through.

Connected Apps

Ask first.
Connect only when needed.

When a task needs an account, Rosi sends a secure Rosi link in your chat. You review the access, continue through the service's sign-in screen, and return to the same conversation. Connected Apps are powered by Composio.

Personal by design

Your Mac is home base.
You stay in control.

Core assistant state lives on your Mac. You choose what Rosi can access, which accounts to connect, and what it should remember. You can create your own reusable skills and keep full ownership of them. Permissions are requested when they are useful—not as a wall of setup screens.
