10 Best Free AI Courses for Marketing and Business Professionals (2026)

If you work in marketing or run a business and you haven’t properly learned how to use AI yet, you’re not behind — but the window is closing. The good news is you don’t need to spend hundreds of pounds on a course. The best AI training available right now comes directly from the companies building the technology, and it’s all free.
I’ve spent time going through dozens of courses so you don’t have to. What follows are the 10 I’d genuinely recommend — not the usual roundup of whatever Coursera surfaces first, but courses I’ve picked because they’re practical, current, and actually useful for people who work in marketing and business.
Note: I run in-company training and public courses on AI for marketing and business. More info here.
What makes a good AI course in 2026?
Before we get into the list, here’s what I looked for — and what you should look for too.
First, genuinely free. Not “free to watch but pay for the certificate,” not “free trial for 7 days.” Actually free. Second, practical. Theory is fine, but you need to walk away knowing how to do something you couldn’t do before. Third, current. AI moves fast. A course from 2023 teaching you about GPT-3 isn’t going to cut it. And finally, relevant. Most AI courses are built for developers. These are built for people who use AI as a tool, not people who build AI as a product.
Here’s the list, roughly ordered from broadest to most specific.
1. Anthropic Academy: AI Fluency — Framework & Foundations
Platform: Anthropic Skilljar (anthropic.skilljar.com)
Length: ~1 hour of video across 14 lectures
Certificate: Yes, free
Best for: Anyone who wants a proper mental model for working with AI
This is Anthropic’s flagship course, and it’s the one I’d start with if I could only recommend one from this list. Rather than teaching you prompt tricks, it teaches a structured framework — the 4D AI Fluency model — for how to think about working with AI. That includes designing prompts, evaluating what you get back critically, and understanding where AI is genuinely useful versus where it’ll waste your time.
It was co-developed with academics from Ringling College and University College Cork, and it’s released under Creative Commons, which tells you something about the quality. It’s tool-agnostic too — you can apply what you learn to ChatGPT, Claude, Gemini, or whatever you use.
Why it matters for marketers: Most people plateau with AI because they never learn how to think about it — they just collect prompts. This course fixes that.
2. OpenAI Academy
Platform: OpenAI (academy.openai.com)
Length: 11 on-demand modules, self-paced
Certificate: Certifications coming late 2025/2026
Best for: Getting hands-on with ChatGPT’s full feature set
OpenAI’s own learning hub covers everything from prompt engineering basics through to deep research, data analysis, reasoning, and using ChatGPT Projects for ongoing work. It started as a developer-focused programme but expanded in 2025 to serve a much wider audience, including small business owners and marketing professionals.
The standout modules are the ones on prompt engineering, data analysis, and deep research — these are the features most marketers underuse. The content comes directly from the team building ChatGPT, so the guidance is as authoritative as it gets.
Why it matters for marketers: If ChatGPT is your primary AI tool, this is the official manual. The data analysis and deep research modules alone are worth your time.
3. Google Cloud Skills Boost: Introduction to Generative AI Learning Path
Platform: Google Skills (skills.google)
Length: ~2 hours total
Certificate: Digital skill badge on completion
Best for: Quick, solid grounding in how generative AI actually works
Google’s free learning path includes three short courses: Introduction to Generative AI, Introduction to Large Language Models, and Introduction to Responsible AI. The non-technical path is specifically designed for people in roles like marketing, sales, HR, and operations — not developers.
It won’t teach you how to use a specific tool, but it will give you a clear understanding of what’s happening under the bonnet. That matters when you’re evaluating AI tools, explaining AI to clients or colleagues, or trying to figure out what’s genuinely useful versus what’s hype.
Why it matters for marketers: When a client or your boss asks “but how does AI actually work?” — this is how you get confident answering that question in two hours.
4. Microsoft GitHub: Generative AI for Beginners
Platform: GitHub (github.com/microsoft/generative-ai-for-beginners)
Length: 21 lessons, self-paced
Certificate: No formal certificate
Best for: Ambitious learners who want to go deeper than surface-level
This is more substantial than most courses on this list. It’s a 21-lesson curriculum with quizzes, diagrams, and hands-on exercises covering prompt engineering, LLM integration, building search applications, and AI ethics. Microsoft built it as an open educational resource and it’s one of the most well-structured free AI learning programmes available anywhere.
It does get technical in places, but the early modules on prompt engineering and practical LLM usage are accessible to non-developers. If you’re the kind of person who wants to understand AI properly — not just use it — this is where you go.
Why it matters for marketers: The prompt engineering and responsible AI sections are immediately applicable. The deeper modules give you a genuine competitive edge in conversations about AI strategy.
5. Semrush Academy: How to Become an AI-Powered Marketer
Platform: Semrush Academy (semrush.com/academy)
Length: ~2 hours
Certificate: Yes, free
Best for: Marketers who want to apply AI to their actual job, today
This is the most directly practical course on the list for working marketers. Led by Michael Olaye, who AdAge recognised as a leading authority on AI in marketing, it covers prompt refinement, AI for strategy development, campaign planning, and content creation. It’s not theoretical — it’s built around real marketing workflows.
What I particularly like is that it goes beyond “here’s how to write a prompt” into how to think about integrating AI across your marketing process. The content creation and campaign modules are the highlights.
Why it matters for marketers: This is the one that’ll change how you work on Monday morning. It’s designed for marketers, by marketers, and it shows.
6. Semrush Academy: AI Visibility Essentials
Platform: Semrush Academy (semrush.com/academy)
Length: ~1.5 hours
Certificate: Yes, free
Best for: Anyone responsible for SEO or content strategy
This is the course most people haven’t heard of yet, and it might be the most important one on this list for anyone working in search. It teaches you how AI is changing SEO — from tracking prompts instead of keywords, to measuring whether your brand appears in AI-generated answers, to building content strategies that get cited by large language models.
If you’ve been wondering what “AI search optimisation” actually means in practice, this is the clearest explanation I’ve found. It covers share of voice in AI responses, prompt mapping across the customer journey, and how to build presence on the third-party sites that LLMs trust most.
Why it matters for marketers: SEO is being fundamentally reshaped by AI. This course gets you ahead of the curve while most agencies are still figuring out what’s happening.
7. HubSpot Academy: AI for Marketers
Platform: HubSpot Academy (academy.hubspot.com)
Length: Short course, ~1 hour
Certificate: Free on completion
Best for: Marketers who want a quick, focused introduction
HubSpot’s AI for Marketing course covers using AI for content creation, personalising customer experiences, and evaluating AI tools responsibly. It’s shorter and less in-depth than some others on this list, but it’s focused and well-produced.
If you already use HubSpot, the integration angle is useful. But even if you don’t, the sections on responsible AI evaluation and practical content creation workflows are solid. It’s a good one to recommend to team members who need to get up to speed quickly.
Why it matters for marketers: It’s the fastest course on this list to complete and it’s specifically built for marketing professionals. Good for getting a team aligned on AI basics without asking for a big time commitment.
8. Microsoft Learn: AI Credentials Challenge
Platform: Microsoft Learn (learn.microsoft.com)
Length: Varies by credential
Certificate: Microsoft Applied Skills credential, free
Best for: Anyone using Microsoft 365 who wants to actually use Copilot properly
Microsoft’s AI learning hub is extensive, but the standout offering is the Credentials AI Challenge, which lets you earn three free applied skills credentials: streamlining business workflows with AI chat, generating reports with AI research agents, and creating agents in Copilot Studio.
What makes these different from watching videos is that they’re scenario-based assessments — you prove you can actually do the thing, not just that you watched someone else do it. If your organisation uses Microsoft 365 and Copilot, this is essential.
Why it matters for marketers: Copilot is increasingly embedded in the tools marketers use daily — Word, PowerPoint, Excel, Teams. Learning to use it properly is the difference between “AI is a gimmick” and “AI saves me hours every week.”
9. Microsoft GitHub: AI Agents for Beginners
Platform: GitHub (github.com/microsoft/ai-agents-for-beginners)
Length: 12 lessons, self-paced
Certificate: No formal certificate
Best for: Forward-thinking marketers who want to understand where AI is heading
AI agents — systems that can take actions, make decisions, and complete multi-step tasks autonomously — are the next major shift in how businesses use AI. Every major platform is building agent capabilities. This 12-lesson course from Microsoft covers the fundamentals: what agents are, how they work, and how to think about deploying them.
It’s more technical than some courses on this list, but even working through the first few lessons gives you a conceptual understanding that most marketers won’t have for another year or two. Each lesson includes a pre-lecture quiz, written explanation with diagrams, and practical exercises.
Why it matters for marketers: Understanding agents now is like understanding social media in 2008. You don’t need to build them yourself, but you need to understand what they can do so you’re ready when the tools mature.
10. Anthropic Academy: Claude 101
Platform: Anthropic Skilljar (anthropic.skilljar.com)
Length: Short course
Certificate: Yes, free
Best for: Anyone who uses Claude (or is considering it)
Claude is increasingly regarded as one of the strongest AI tools for professional work — particularly for writing, analysis, and complex reasoning tasks. This introductory course from Anthropic covers the core features, everyday use cases, effective prompting, and an honest look at capabilities and limitations.
You don’t need a paid Claude subscription to take it — just sign up with your email at anthropic.skilljar.com. If you’re already a Claude user, it’ll likely fill in gaps you didn’t know you had. If you haven’t tried Claude yet, it’s a structured way to get started.
Why it matters for marketers: Claude excels at the kinds of tasks marketers do every day — drafting content, analysing data, summarising research, and building strategies. Learning to use it well gives you a second tool alongside ChatGPT, and sometimes it’s the better one for the job.
How to get the most out of these AI courses
Taking a course isn’t the same as learning a skill. Here’s how to make sure the time you invest actually pays off.
Start with one. Don’t try to do all ten. Pick the one that matches where you are right now. If you’re brand new to AI, start with the Anthropic AI Fluency course or the Google learning path. If you already use AI daily, go straight to the Semrush AI Visibility course or the Microsoft agents curriculum.
Apply immediately. After each module, use what you’ve learned on a real task. Wrote a prompt? Use it on a real brief. Learned about AI search? Check whether your brand appears in ChatGPT’s answers. Theory without practice evaporates.
Layer your learning. These courses complement each other. The Anthropic AI Fluency course teaches you how to think. The OpenAI Academy teaches you how to use ChatGPT specifically. The Semrush courses teach you how to apply AI to marketing specifically. That’s a progression worth following.
