Claude Cowork plugins will kill most AI SaaS products. Here's why I believe that.

I spent months trying to build a SaaS. It didn't work.

Went back to client work — lead gen pipelines, Apollo to Instantly campaigns. That paid the bills. But I couldn't manage my business and stay consistent on LinkedIn at the same time.

So I built ALGA — an AI LinkedIn Growth Assistant — as a Claude Cowork plugin. It reads my Airtable base, knows my projects, my voice, my content pillars, and helps me draft posts and comments with full context. I approve everything before it goes out.

No subscription. Runs on my machine. Knows who I am.

Here's what SaaS products can't do: you can't customize them. You get the features they decided to build, in the way they decided to build them. A plugin is different — you define the behavior, the context, the commands. It's yours entirely.

And now with API access to platforms like LinkedIn, WhatsApp, and most business tools, the infrastructure is already there. Plugins can tap directly into the same data these SaaS products use — without the middleman, without the monthly fee, without the limitations.

That's the shift I see coming. Plugins won't just compete with SaaS. They'll make a lot of it unnecessary.

Just published my first build video if you want to see ALGA live: https://youtu.be/nvbNtQjmr-s

What are you building with plugins right now?
