Amazon Nova Act

What is Amazon Nova Act?

Amazon Nova Act is a model trained to perform actions inside a web browser, paired with an SDK for building agents that drive a browser reliably. It comes from Amazon's AGI lab and targets a known weak spot of browser agents: doing many steps in a row without drifting off course.

The approach is to compose: instead of one open-ended instruction, you break a workflow into small, specific actions (click this, fill that, extract these fields) and let the SDK chain them, mixing in your own Python where it helps. That makes the resulting agent easier to test and more dependable.

Nova Act is aimed at developers who want to automate web tasks that have no clean API. It has been offered as a research preview, so treat it as an evolving building block and confirm availability and terms before depending on it.

Strengths

What it's best for

  • Automating web workflows that lack an API, broken into small reliable steps.
  • Developers who want to script browser actions and interleave their own code.
  • Building testable agents where each step can be checked rather than one big prompt.
  • Teams in the AWS and Amazon ecosystem exploring browser automation.
Limits

Where it falls short

  • Non-developers: it is an SDK and model, not a finished consumer agent.
  • Production-critical workflows before you have validated reliability for your case.
  • Sites whose terms forbid automated access, which you must check first.
How to use it

Ways in

Use the Nova Act SDK with an API key. You write a script that issues small, specific browser actions and let Nova Act carry each one out.

Decompose the workflow: rather than one broad instruction, give a sequence of narrow steps, and add Python around them for logic, retries, and checks.

How to use it

Getting the most out of it

Keep each action small and verifiable; reliability comes from composition, not from one long prompt.

Add assertions between steps so the agent fails loudly when a page is not in the expected state, rather than drifting.
