Why Claude

It's not “prompts for ChatGPT”.

Claude is the model companies choose to really build: code, agents, and automation with judgment. Here you don't learn tricks that expire in a month — you learn Anthropic's professional ecosystem: the API, Claude Code, MCP, Tool Use, and the agents that are already changing how work is done.

GPT vs Claude

Why get trained on Claude

Both are excellent. But for building —programming, automating, setting up agents— Anthropic's ecosystem makes the difference.

The three pieces that make a difference

Claude Code

The agent that programs with you

Stop copying and pasting. Claude Code works on your own project: reads your code, edits files, runs tests and automates repetitive tasks from the terminal.

→ Refactors and documents entire projects
→ Create your own skills and commands
→ Automate workflows with controlled permissions

MCP · Model Context Protocol

Give Claude your data and tools

MCP is the open standard created by Anthropic to connect AI with the real world: your documents, databases and APIs, securely and in a standardized way.

→ Connect Drive, databases and your APIs
→ Set up your own MCP server step by step
→ The same standard used by companies

// mcp-server.json
{
  "tools": [
    "buscar_facturas",
    "leer_drive",
    "escribir_hoja"
  ],
  "context": "tu negocio"
}

Agents

Agents that work alone

An agent reasons, decides which tool to use and executes the complete task. You learn to design them, set their limits and deploy them to work for you.

→ Design of reliable and judicious agents
→ Orchestration of multiple agents
→ From idea to production

# agente de facturas

  doc = leer(drive)
  datos = extraer(doc)
  registrar(datos)
  → ✓ 47 procesadas

Project certificate · verifiable

You finish with a certificate that says something real

It's not a 'I watched a video' diploma. It certifies that you have designed, built and implemented your own agent with Claude, with a public verification code that anyone can check. It doesn't certify theoretical knowledge: it certifies having built something that works.

Who is behind it

Jorge Fernández Aguila with his book La Generación IA

Jorge Fernández Aguila
Founder · instructor · author of the books

I build real products with Claude every day —agents, automations, and software— and I teach exactly that: what works in production, not hype. The course is built on Anthropic's official documentation and is kept up to date.

HONEST

Newly launched academy: you won't see hundreds of reviews yet. I compensate with lifetime access and included updates — and I answer every question personally.

Doubts

Frequently Asked Questions

Who is it for? +

For developers, professionals, and entrepreneurs who want to master Anthropic's AI and apply it for real: automate, program, and build.

Anthropic has launched Claude Academy for free. Why pay for this? +

Because they do different things, and we recommend doing both. Claude Academy is the official Anthropic training: excellent, free, and always up-to-date — 22 courses, with 9 hours of API alone. It has two limits: it's in English and it's manufacturer training, meaning it ends where your work begins: it teaches you the pieces, not your project or how to charge for it. MasterEnClaude is available in English, Spanish and Russian and picks up right there: 6 levels and 88 lessons that take MCP, Claude Code, agents, and API to a real business —invoices, email, databases, content, and SEO— and an entire module on selling what you learn (freelance, consulting, or your own SaaS), with exercises, tests, and a certificate. We tell you all about it without embellishments in this article.

Do I need to know how to program? +

It helps, but we start from the fundamentals and progressively level up. There are very practical parts where you will write code guided step by step.

Is it updated with the latest Claude models? +

Yes. It covers the current Anthropic ecosystem —the latest Claude model family (including Fable generation), Claude Code, MCP, Tool Use, and agents— and is updated when there are new developments. Your access includes updates.

Is the course video or text-based? +

It's a written and practical course: detailed lessons, exercises, and self-assessable tests with progressive unlocking and a final certificate. The Professional plan also includes the videos for all 10 modules.

When does the new edition open? +

The new edition is planned for mid-November. We are preparing it because we are updating the whole course to the current Claude models (Opus 5.5, Sonnet 5.5, Haiku 5.5 and Fable 5.1). Stay tuned! If you join the waitlist, you will be among the first to know, before we announce it publicly. It is free and there is no commitment.

How long do I have access? +

Lifelong. The course is yours, with updates included.

Do you provide an invoice? +

Yes, request it at info@masterenclaude.com.
