The internet, for a day.

Agents keep running into the same wall. They can write, reason and call tools, but they cannot receive a file from a person, hand one over, or take a callback from a service, because none of that exists until someone makes a URL. hello.new makes the URL.

The idea

Almost every real task has a moment where the agent needs the outside world to reach it. Get the accountant to send the CSV. Show the client the draft. Wait for Stripe to say the payment went through. Today that moment ends with a human creating a bucket, a form, a tunnel or a deploy. We wanted it to end with one HTTP call, from the agent, with nothing to sign up for.

So hello.new is a small set of primitives that answer one sentence: I need a temporary internet resource. An upload link. A shared page. A webhook. Each is a single POST that returns a branded URL for the person or service, a key for the agent, and an expiry. Then it is gone.

Why anonymous and temporary

  • The agent is the user. It cannot fill in a sign-up form in the middle of a task, and it should not have to. No account means the first call works.
  • Temporary is a feature. Most of these resources are needed for an hour. Expiring by default keeps the service clean and means nobody has to remember to delete anything.
  • The URL is the product. Every link carries the name. The person who receives one finds out what it is by using it, which is the only kind of advertising we plan to do.
  • Machine-readable first. A skill, an llms.txt, an agent.json and an OpenAPI description, so an agent can discover the whole thing without a human reading this page.

How we make money

Not from the first webhook, or the hundredth. Anonymous, temporary use stays free, and so does keeping links under a name of your own. Pro is for agents that keep a lot: more storage, bigger files, busier webhooks. We charge for keeping a lot, not for trying things.

What is next

A one-time secret handover, once its security model is boring enough to publish. Longer retention behind an account. Listings wherever agents install skills. And we would rather add fewer primitives that agents actually reach for than a catalogue.

Agent addresses

hello.new began as addresses for assistants: @you/name, with a web chat and an MCP endpoint that relays to the computer the assistant runs on. That still works and is documented at /docs/addresses.
