The Idea Behind Jetro

Give everyone with AI
an infinite canvas

No subscriptions. No vendor lock-in. No limits. Just your editor, your agent, and a canvas that can become anything.

There's nothing like it

No tool lets you explore data, write custom logic, run deep analysis, and see it all on a visual canvas. Not in one place. So we built one.

AI agents are the unlock

The most powerful LLMs already run inside code editors. They can build apps, dashboards, automations. Anything, really. All they need is the right tools and a surface to create on.

Your machine, your data

Everything stays local. Files on disk. DuckDB on your machine. No cloud databases, no data leaving your laptop. Use whatever AI you already have. Zero lock-in.

Free. Actually free.

No pricing tiers, no "free trial", no credit card. Jetro is free because the best tools are the ones people actually use. We want it in everyone's hands.

One canvas. Infinite possibilities.

Your agent builds it. You arrange it. Live data keeps it fresh.

Product A drove most of the growth this quarter. Consider increasing allocation. Service D needs review — third month of decline.

What is Compound Interest?
Interest earned on both the initial principal and the accumulated interest. The formula:
A = P(1 + r/n)^(nt)
Where P = principal, r = rate, n = compounds/year, t = years

Who we are

The most powerful AI models today run inside code editors. Claude, GPT, Gemini. They can build dashboards, analyze data, create apps, write reports. But most people never touch that power because code editors feel like they're made for programmers. And even for the people who do use them, there's no visual surface. Just text in, text out.

Jetro fixes that. We added an infinite visual canvas to the code editor, where AI shows its work. Charts, tables, live dashboards, interactive tools. You talk to it in plain English. No code, no commands, no learning curve. Whether you're a student exploring data for the first time or a professional tracking live markets, it just works.

We built Jetro for everyone who wants to do more with AI. A teenager building their first stock tracker. A teacher creating interactive lessons. A researcher tearing through 200-page reports. A team watching live data on a shared screen. If you can describe what you want, Jetro helps your AI build it.
