A practical, no-code guide to the new class of AI browsers and computer-use agents that browse and act on your behalf. Learn how they work, compare ChatGPT Atlas, Perplexity Comet, and Gemini in Chrome, run real research and automation workflows, steer them safely, and defend against prompt injection and data exposure.

AI browsers arrived fast in 2026, and suddenly your browser can read pages for you and, in agent mode, click and type on your behalf. This beginner-to-intermediate course is a practical, no-code guide to using that power without getting burned. You do not need to write code or install anything exotic. You need clear judgment about what these tools do well, where they fail, and how to keep control, and that is exactly what you will build here.
Across nine hands-on lessons you will learn how computer-use agents perceive a screen and act one step at a time, tour the 2026 landscape (ChatGPT Atlas, Perplexity Comet, Gemini in Chrome, and Dia), and choose the right tool for your device and budget. You will run real research and summarization workflows, automate multi-step tasks like comparison shopping, and master the four levers of steering an agent: goals, guardrails, checkpoints, and takeover. The course's centerpiece is a serious security lesson on indirect prompt injection, the attack where a web page hijacks an agent that holds your logged-in sessions, plus a practical hygiene checklist you can apply immediately.
This course is for curious professionals, students, and anyone who wants to adopt agentic browsing deliberately rather than accidentally. It is 100% free from start to finish, and passing the final exam earns you a free certificate of completion you can add to your LinkedIn profile and resume.

Yes. Every lesson, quiz, and the final exam are completely free, and you earn a free certificate of completion when you pass.
No. This is a no-code course about using, evaluating, and safely steering AI browsers, not about building your own agent framework.
It covers the 2026 landscape at a practical level: ChatGPT Atlas, Perplexity Comet, Gemini in Chrome, and Dia, plus the computer-use APIs underneath. Always confirm current prices and platforms on each vendor's page, since they change fast.
No. Many assistant features are available on free tiers, and the course teaches you to start there. Agent mode features are often gated behind paid tiers, but the skills apply either way.
How to use agent mode safely. The security lesson on prompt injection and data exposure is the course's key differentiator and the skill that matters most as these tools spread.
