My Product

What I am Building Now

SerperMatrix

Real-time web access for AI agents

SerperMatrix started as a tiny MVP I built in a panic… because my AI agent kept asking for “real-time web data,” and I got tired of pretending Google didn’t exist.

So I built my own API. Fast. Clean. Ridiculously efficient. And then I realized— hey, this thing is actually good.

Now SerperMatrix gives you instant search data, AI-ready markdown, HTML when you need it, and a bunch of endpoints that make your agents stop complaining.

It’s the tool I created because I needed it… and now you get to use it without suffering through the 3 AM debugging sessions I did.

If your AI needs real web access without the keep saying "Yeah, you are correct I missed there"— SerperMatrix is my love letter to developers who just want things to work.
