What Courses and Programming Languages Are Available on Sololearn?

Sololearn offers more than 20 courses spanning programming languages, web development, data, and AI, with most language tracks split into introductory and intermediate levels. The catalog is organized into named course tracks rather than a single flat list, so you can pick a language path or a topic path depending on your goal. All courses are described as interactive and hands-on, with lessons, in-lesson quizzes, and practice built in.

Programming language courses

The core language catalog covers the most common beginner and intermediate languages:

The pattern here is a two-step ladder: an "Introduction to" course for first exposure, then an "Intermediate" course once you have the basics. HTML and CSS appear as standalone introductory courses rather than paired with an intermediate level, which fits their role as entry points into web development.

Web development and front-end

Beyond individual languages, Sololearn groups web-related material into tracks:

• Web Development — a broader track that combines front-end skills
• Front-end for Beginners — an entry point for people starting with the browser-facing side of the web
• Angular — a framework course for those moving past plain JavaScript

If your goal is building pages, the natural sequence is Introduction to HTML → Introduction to CSS → Introduction to JavaScript, then Front-end for Beginners or Web Development for structure. Angular comes later, once JavaScript is comfortable.

Data and analytics

Data-focused courses include:

• Coding for Data
• Data Analytics with AI
• Visualize Your Data
• Introduction to SQL and Intermediate SQL (also listed under languages, but central to data work)
• Data Literacy with AI

These mix traditional data skills (SQL, visualization) with AI-assisted workflows, which reflects how the catalog has expanded beyond pure programming.

AI and machine learning

This is the largest and fastest-growing part of the catalog. Courses include:

• Generative AI in Practice
• Introduction to LLMs
• Machine Learning for Beginners
• Prompt Engineering
• Ethical AI Foundations
• AI Agents for Beginners: How They Work (Python)
• Agentic Workflows
• Bias Detection and Mitigation in AI Systems
• AI-Powered A/B Testing
• AI-Powered Product & UX
• Write with AI, Brainstorm with AI, Think Creatively with AI, Research with AI, SEO with AI
• Project Planning with AI, Social Media Marketing with AI
• Vibe Coding
• Critical Thinking – AI Era
• Growth Mindset in the Age of AI
• Meet Claude

Note that several of these are applied AI courses aimed at non-programmers (marketing, SEO, product, planning), while others (Machine Learning for Beginners, AI Agents for Beginners) assume some coding ability.

Foundations and general skills

For people who want a starting point before committing to a language:

• Coding Foundations
• Tech for Everyone
• Python Developer (a broader track rather than a single course)

How the levels work

Sololearn structures most tracks as Introduction → Intermediate, with quizzes inside lessons to check understanding and certificates available on completion. The site describes lessons as "bite-sized" and step-by-step, and states that learners write real, functional code within minutes of starting. Progress syncs across web, iOS, and Android, so you can switch devices without losing your place.

Choosing a path

• Never coded before: Coding Foundations or Tech for Everyone, then Introduction to Python.
• Want to build websites: Introduction to HTML → Introduction to CSS → Introduction to JavaScript → Front-end for Beginners.
• Interested in data: Introduction to SQL → Coding for Data → Visualize Your Data.
• Curious about AI but not a programmer: Prompt Engineering, Generative AI in Practice, or one of the applied courses like SEO with AI.
• Already know a language: jump straight to the Intermediate course for that language.

The catalog is described as continuously updated, and the AI section in particular has grown well beyond the original language courses. Pricing details for full access are listed separately on Sololearn's pricing page, so check there if you need to know what the free tier covers versus paid plans.
