Are these tools really free?

Yes. Every tool here is free, with no trial and no watermark on anything you make.

Do I need to sign up?

No. Open a tool and use it. There's no account, and you never need to give an email to see a result.

Can I use the results for client work?

Yes. What you make with a tool is yours to use, for your own work or for a client's.

Do you keep what I paste in?

No. The tools that run in your browser never send what you type to a server. Some keep your last draft in your own browser, so it's still there when you come back, and you can clear it at any time.

Where does the work happen, in my browser or on a server?

In your browser, for most tools. A tool that has to fetch something, like a web page, sends only that link to my server, and the tool says so.

Is anything I paste used to train AI?

No. Nothing you paste is stored, so there's nothing to train on.

Can I suggest a tool?

Yes. Tell me the job you want done and I'll look at it. Send me a message with the tool you'd like.

How do you pick what to build next?

I build the tools people ask for most, and the ones that fit what I teach: AI, content and running a business on your own terms.

Will I hear back when it's live?

Yes, if you leave your email when you suggest it. I'll let you know when the tool is live.

Who is Navid Moazzez?

I'm an AI business strategist and the host of the AI Creator Summit, watched by 100,000+ creators. I help creators and founders master AI and build their own AI Operating System (AI OS) to automate their business and life.

Why does Navid build free tools?

Because a tool you can use in a minute is the fastest way to show how I work, and it helps you right away.

How do these tools connect to the AI OS?

An AI OS connects your AI to your context, your data and your tools, so it can do the work for you. Several tools here link to the open source MCP server and CLI or the skill that does the same job inside your AI, so you can go from doing it by hand to having your AI do it.
