Sololearn: free coding, AI and data courses

Sololearn currently maintains a free-learning route across its coding and technology catalogue. The official learning page states that many courses, including coding, AI literacy and game design, are completely free to start. The catalogue includes introduction courses such as Python, C and C#, as well as broader learning paths for coding foundations, web development, data and front-end skills. Sololearn also offers paid Pro and Max plans for expanded access, practice and shareable certificates, so the free route should not be interpreted as every premium feature being included. Learners can browse the official course catalogue and begin a course that is currently available through the free tier.
