I lead Business Systems and AI Enablement at a software company, and I've watched plenty of AI tools get installed and quietly abandoned. Rebel is one that stuck.
What sets it apart from a chat window is that it plugs into the actual work. It connects to all our SaaS apps with API or MCP access, then acts across them. One team has it pull from several systems every Monday and draft a leadership briefing, replacing an hour of manual system hopping. A product manager connected it to a live codebase and shipped a real UI change in under two hours. Our sales team is running roughly 30% more demos because Rebel handles most of the admin work in the CRM for them. None of this is staged. It's daily use.
Three things I rate:
Memory done right. It distinguishes what's private to me, what's for my team, and what's company wide, and stores things accordingly. That's the foundation of trust.
Automations and skills. You teach it a workflow once and it runs on a schedule, so the time savings compound.
Privacy by design with a real safety layer. It drafts rather than auto sends and asks before anything sensitive.
It's not flawless. Complex tasks take time, and it wants capable hardware. But the output quality makes the wait worth it.
If you want a chatbot, there are cheaper options. If you want an agent that lives inside your tools and does the work, this is the one I'd back.

Thanks for the thoughtful review. We’re working on the speed bit as we indeed built it for “real work” (as opposed to many others which did this the other way around).
Cost is also very high on the roadmap, with real movement already from next week
