Amazon Nova Act Goes Live: AI Browser Agents Hit 90% Reliability in Enterprise Production

The wait is over. Amazon Web Services today announced the general availability of Nova Act, its browser automation AI service that's already achieving a remarkable 90% reliability rate in enterprise production environments. This isn't another AI demo—it's a fully deployed system that's actively replacing human workers in browser-based tasks across major corporations.

The Reliability Breakthrough That Changes Everything

Here's what makes Nova Act different from the parade of AI automation promises we've seen: it actually works consistently. AWS engineered this through a custom Nova 2 Lite model trained via reinforcement learning across thousands of tasks on hundreds of simulated web environments.

The 90% reliability threshold is crucial. It's the difference between "interesting prototype" and "deploy this to replace our QA team tomorrow." And that's exactly what's happening.

Real Companies, Real Results, Real Job Displacement

Hertz accelerated software delivery by 5x and eliminated its Quality Assurance bottleneck by deploying Nova Act for end-to-end testing across its rental platform. Let's translate that corporate speak: Hertz cut QA headcount while dramatically improving output. The people who used to manually click through test scenarios? Nova Act does it faster, more thoroughly, and never calls in sick.

Meanwhile, startup Sola Systems integrated Nova Act to automate hundreds of thousands of workflows per month for their clients. We're talking about automating "business-critical tasks like reconciling payments, coordinating shipments, and updating medical records." These aren't edge cases—these are core business operations that previously required human workers.

Technical Capabilities: Beyond Simple Form Filling

Nova Act handles the full spectrum of browser-based work that currently employs millions:

• Form filling and data entry: Goodbye, administrative assistants
• Search and extract operations: Research analysts, take note
• Shopping and booking workflows: Customer service reps, this one's for you
• Quality assurance testing: QA teams, we've seen how this ends
• Payment reconciliation: Finance clerks, start updating that LinkedIn
• Medical record updates: Healthcare administration, you're next

The Developer Experience That Accelerates Deployment

AWS made Nova Act ruthlessly easy to deploy. You start in the Nova Act Playground, where you prototype agents using natural language descriptions. No complex configuration, no downloading specialized software—just describe what you want automated and test it immediately.

Then you move to the Nova Act extension for VS Code, Cursor, or Kiro to refine your agent. This streamlined workflow means companies can go from "let's automate this process" to "production deployment" in weeks, not months.

The Economics of 90% Reliability

Here's the math that terrifies human workers: At 90% reliability, Nova Act agents are already more consistent than most human employees. Factor in 24/7 availability, no benefits, no vacation time, and no training costs, and the economic case becomes overwhelming.

Even if Nova Act fails 10% of the time, companies can structure workflows where human oversight handles exceptions while agents tackle the bulk of routine work. This hybrid model eliminates the majority of positions while keeping a skeleton crew for edge cases.

What This Means for the Workforce

Nova Act's general availability represents more than a product launch—it's the moment browser automation became industrially viable. The service targets the exact type of work that employs millions of office workers: clicking, typing, copying, pasting, and following standardized procedures.

The companies already deploying Nova Act aren't piloting the technology—they're scaling it to replace human workflows entirely. When Hertz can eliminate QA bottlenecks and 5x delivery speed, the competitive pressure to automate becomes irresistible.

For workers in affected roles, the window for adaptation is narrowing rapidly. Browser-based administrative work, data entry, basic customer service, and routine testing are becoming automated by default, not by exception.

The Broader Context: AI Automation Goes Mainstream

Nova Act's launch coincides with AWS re:Invent 2025, where Amazon positioned agentic AI as the next phase of cloud computing. This isn't experimental technology anymore—it's infrastructure-as-a-service for workforce automation.

The combination of 90% reliability, easy deployment, and immediate ROI creates perfect conditions for rapid adoption. Companies that don't automate these workflows will find themselves at a massive competitive disadvantage against those that do.

The question isn't whether browser automation will reshape the workforce—it's how quickly. With Nova Act now generally available and proven at enterprise scale, that timeline just accelerated dramatically.
