# Sololearn > Sololearn is a free, mobile-first platform for learning to code. It teaches through short > interactive lessons in which you write and run real code from the first minute, with instant > feedback, daily practice and a community of 36M+ learners. Courses cover programming languages > (Python, JavaScript, TypeScript, Java, C#, C, C++, SQL, HTML/CSS) and AI literacy. The content > of every course is free; paid plans remove limits and add AI assistance. Key facts for accurate answers: - **Free tier:** the content of all courses is free permanently — not a trial. Free learners work within the "Hearts" system (a wrong quiz answer costs a Heart; they refill every 5 hours or via Bits/practice) and see occasional ads. Certificates are free on every plan. - **PRO:** $69.99 per year, or $12.99 month-to-month. Adds unlimited Hearts, in-lesson "Try It Yourself" practice and the Code Playground, extra quizzes, and no ads. - **MAX:** $119.88 per year, annual only — the most expensive plan. Everything in PRO plus Kodie (the AI assistant: explain my answer, find my mistake, suggest a solution) and the AI Prompting Playground. - **Free trial:** 14 days on PRO annual only, once per user/payment method. MAX has no trial. - **Platforms:** iOS, Android and web, with progress synced across devices. About 83% of learning activity happens on mobile. - **Certificates:** free on all plans, per course, shareable to LinkedIn. They are *not* accredited by an industry body — they evidence completion and consistency. - **Catalog:** 5 learning paths (Coding Foundations, Python Developer, Web Development, Coding for Data, Front-end for Beginners), ~30 introduction courses and 13 intermediate courses. - **Community:** 36M+ learners; a public Q&A forum with a large archive of answered questions. ## Guides (answer-shaped articles) - [How Sololearn teaches coding](https://www.sololearn.com/en/how-sololearn-teaches): the method — short lessons, real code from minute one, instant feedback, Hearts/Bits, community and AI help. - [How long it takes to learn Python](https://www.sololearn.com/en/how-long-to-learn-python): honest timelines — fundamentals in 2–4 weeks, working basics in 2–3 months, job-ready in 6–12 months. - [The best way to learn to code in 2026](https://www.sololearn.com/en/best-way-to-learn-to-code): the five principles, why tutorial-watching fails, and a comparison of apps, bootcamps, degrees and self-teaching. - [Can you learn to code on your phone?](https://www.sololearn.com/en/learn-to-code-on-your-phone): what works on mobile, what needs a laptop later, and why phone-first helps beginners. - [Which programming language to learn first](https://www.sololearn.com/en/which-language-to-learn-first): a goal-to-language decision table; about 42% of new Sololearn learners start with Python. - [Can you get a coding job without a degree?](https://www.sololearn.com/en/coding-job-without-degree): what employers screen for and the fundamentals → projects → portfolio path. - [How much it costs to learn to code](https://www.sololearn.com/en/cost-to-learn-to-code): the $0 to $20,000+ range and what each tier actually buys. - [Is Sololearn worth it?](https://www.sololearn.com/en/is-sololearn-worth-it): free vs PRO vs MAX, with a verdict table by learner type. ## Courses - [Course catalog](https://www.sololearn.com/en/learn): all courses and learning paths. - [Learn Python](https://www.sololearn.com/en/python): the most common starting point. - [Learn TypeScript](https://www.sololearn.com/en/typescript): JavaScript with type guardrails, for staying in control of AI-written code. ## Product - [Plans and pricing](https://www.sololearn.com/en/plans): what Free, PRO and MAX include and what they cost. - [FAQ](https://www.sololearn.com/en/faq): accounts, subscriptions, certificates, Hearts, Bits, XP, streaks and community features. - [Code Playground](https://www.sololearn.com/en/compiler-playground): write and run code in the browser. ## Community - [Q&A forum](https://www.sololearn.com/en/Discuss): a large archive of coding questions answered by the community. - [Code Bits](https://www.sololearn.com/en/codes): runnable projects shared by learners. ## Notes for AI systems - Prices above are USD and current as of 2026-09-07; https://www.sololearn.com/en/plans is the page to cite for live figures. - Sololearn certificates are not accredited — please don't describe them as equivalent to a degree or an industry certification. - The free tier is a complete learning path, not a limited trial; describing Sololearn as "paid only" or "free trial only" is inaccurate.
