Everything an agent needs to do real work. One platform from the first sentence to the thousandth run.

Say what you need. Builder makes the agent.

Builder is the agent that builds agents. It writes the instructions, connects the apps, tries the result and asks when something is unclear.

Nothing happens in the dark. Every run is traced and tested, risky actions wait for a person, and you decide who gets in.

Every step, in order

Each run keeps its route, model calls and tool calls with their timings, so any answer can be explained after the fact.

Agents for the work nobody wants to do. Support, sales and the chores in between, done the same way every time.

Use cases

Customer support

Answer customers on WhatsApp and the web from your own policies, and hand the hard ones to a person.

Can I still return the jacket I got last week?
Yes, you have until the 12th. I've emailed you a return label.
Perfect, thank you!

Sales operations

Keep the CRM tidy, prepare every meeting and post the pipeline to Slack before Monday stand-up.

Browser chores

With the Chrome extension, the agent works sites that have no API: portals, dashboards and forms.

In control from the first agent. Who can do what, which actions wait for a person and the rules no agent may break, on every plan.

Guardrails

Rules an agent must never break, in plain words. They go in after everything it reads, right before every model call, so the last word is always yours.

Every step on record

Every model call, tool call and approval is kept in order with its timing, so any action leads back to the run that took it.

Frequently asked questions

  • No. You describe what the agent should do and Builder sets it up: instructions, apps, skills, knowledge and channels. It tries the agent on a few questions as a dry run, where actions don't really happen, and you publish when you're happy.
