Mindstone Rebel
A local AI workspace that connects your work and asks before it acts
Overview
Rebel is Mindstone's attempt at agentic AI that doesn't ask you to hand over the keys blindly. It's a desktop workspace that connects your calendar, files, meetings, and tools so an AI agent can actually help with day-to-day work, but anything sensitive requires a human approval step before it goes through. It's Fair Source and local-first, meaning you can download it, run it on your own machine, and inspect what it's doing, and any given version converts to MIT open-source 24 months after release.
It's built for individuals and teams who want the productivity of agentic AI without the anxiety of an agent quietly taking actions on their behalf. Mindstone itself is better known for AI skills training than software products, so Rebel is a newer bet for the company, but the "ask first" design and local control are a genuinely sensible response to how nervous people are about giving AI agents free rein. It's free for individuals and organizations under 100 concurrent users, with a paid Mindstone Pro license kicking in above that threshold.
Key Features
Approval Checks: Sensitive actions stay behind a human approval step instead of running automatically.
Local-First Desktop App: Runs on your machine, so you can inspect, customize, and control what data it touches.
MCP Connectivity: Connects to your own tools through the Model Context Protocol rather than a closed integration list.
Chief-of-Staff README: A local file that separates private, team, and company-wide context so agents know what they're allowed to see.
Model Choice: Portable workflows that aren't locked to a single AI provider.
Impact Dashboard (Pro): Shows where Rebel is saving time and money across business units.

What Makes It Unique
