Two products. One way of working.

Meet ROS and the Rosanne Agentic OS.

Agentic web browser · Mac and iPhone

ROS

Private by design. Agents on the way.

A fast, private browser built on WebKit. Trackers are blocked from the start and your history stays on your device.

  • Ads and trackers blocked before pages load
  • History encrypted on your device, no account needed
  • Ask Rosanne: agents coming soon

Agentic operating system · Voice AI built in

Agentic OS

Talk to your agents.

Say or type the outcome you want. Agents with clear roles plan it, make the calls, automate the routine steps and report back. Every step stays visible.

  • Voice AI: talk to your agents, and they take your calls
  • Automation takes care of the routine steps
  • You set permissions and approve key steps

How it works

Four steps from goal to done.

You stay in the loop at every one.

  1. 01

    Ask

    Say what you need in plain language, the way you would brief a colleague.

  2. 02

    Plan

    Agents turn the goal into a plan of clear steps, each one visible to you.

  3. 03

    Approve

    Important actions wait for your approval before they happen. You set the permissions.

  4. 04

    Report

    Agents finish the work and report back, with an activity trail and sources you can check.

Our answer

Build for people.

  • 01

    Augment people

    Agents take on the repetitive, multi-step work, so people spend their time on judgement and ideas.

  • 02

    Retain knowledge

    Shared knowledge keeps expertise with the team, even as people and roles change.

  • 03

    Upskill the workforce

    Working alongside agents is a skill. Rosanne helps people build it for the jobs that are coming.

  • 04

    Include more people

    New work should reach everyone, with a strong ecosystem across Africa and emerging markets.
