LearnPath is a free alternative to Coursera, Udemy, and Skillshare. Built for self-taught learners who want course-quality structure without paying $49 to $79 a month or $200 per course. I built it because YouTube already has the best content for almost any skill. The problem is structure....

As answered by people managing CheckIO and LearnwithPath.com.
LearnwithPath.com's answer:
YouTube has the best content for almost any skill, but no structure. Coursera and Udemy have structure but cost $49 to $79 a month or $200 a course. LearnPath gives you the structure of a paid course on top of free YouTube videos, and the path adapts based on how you score on quizzes. The free tier is fully usable, not crippled. Knowledge actually sticks because spaced repetition is built in.
LearnwithPath.com's answer:
It's free for the core experience and the paths actually adapt to you. Coursera locks fixed curricula behind a paywall. Udemy buries you in 40 hour video dumps with no quiz logic. Skillshare is project-based, not skill-based. LearnPath builds a path from real videos, generates quizzes from the actual transcripts of those videos, and reshapes the path based on your performance. Spaced repetition reviews are scheduled automatically so what you learn sticks. No setup. No API keys. Sign up and start in under a minute.
LearnwithPath.com's answer:
Self-taught learners. Career switchers ramping up on a new tech stack. Students preparing for technical interviews. Developers picking up a new language or framework. Designers learning a new tool. Anyone who has tried piecing together a YouTube playlist and wished it had structure, quizzes, and progress tracking. Mostly people who would rather learn for free than pay $49 a month for Coursera.
LearnwithPath.com's answer:
I taught myself programming, development, and most of what I know from YouTube. There is an enormous amount of high-quality material on the platform but no structure and no real way to know if you are actually learning. After years of stitching together my own playlists, I built LearnPath to fix that for everyone else. An AI takes any topic, assembles a personalized course from the best YouTube videos, and adds quizzes and spaced repetition so the knowledge actually sticks. The best part is that it's free.
LearnwithPath.com's answer:
Frontend is Next.js 14 with React, TypeScript, and Tailwind CSS. Backend is Python with FastAPI. Database, auth, and realtime are on Supabase with row level security. AI is Google Gemini for video curation, quiz generation, and the adaptive branching logic. Video data comes from YouTube Data API and youtube-transcript-api. Payments are on Airwallex. Errors and analytics are on Sentry and PostHog.
