Web automation that learns the site,
then runs it deterministically.

A3 uses LLMs to learn each site and writes Playwright scripts once — then the runner replays them with no model in the loop. 99% cheaper* and 10× faster than LLM-controlled agentic browsers.

*based on 1000 automations with different input criteria

— Setup

Define the workflow.

Describe the automation in plain English.
A3 asks clarifying questions, then proposes schemas and the site steps you need.

— Learn

Learn the site.

Tell A3 which site to automate.
It navigates in the browser and writes verified Playwright stages one by one.

"Vitruvian Man" — one model, any use case.

— Run

Run deterministically at scale.

Create A3 jobs via the Automation Cloud API — 0 tokens, no LLM required.
Or expose the same project as MCP / UCP tools for agents.

"Terracotta Warriors" — runners at scale.
