Why we built this
AI is changing everything. But most AI tools are generic. They know a bit about a lot of things, and not much about anything specific.
We think the best AI tools come from real experts. People who've spent years mastering a craft, building portfolios, running businesses, solving real problems. When you combine that hard-won expertise with AI, you get something extraordinary.
That's what Cowork Plugins is. A marketplace where domain experts package their knowledge into AI plugins that anyone can use. Starting with property investment, because that's where we have the deepest expertise.
Every plugin on our marketplace carries the Made by Human certification. This means a real person with verified experience built it. Not a script. Not a scraper. A human who's done the work.

What Makes Us Different
Expert-first, not AI-first
The human expertise comes first. AI amplifies it. This is the opposite of auto-generated content dressed up as knowledge.
Verified creators
We check that plugin creators have genuine domain experience. Track records, not just marketing claims.
Quality over quantity
We'd rather have 12 brilliant plugins than 12,000 mediocre ones. Every listing is reviewed and tested.
Built for real people
You don't need to be technical. Install a plugin, ask it questions in plain English, get expert-level results.
