About HintForge
Your AI-powered companion for mastering data structures and algorithms
Our Mission
HintForge is designed to help aspiring software engineers master data structures and algorithms through intelligent, progressive guidance—not solution dumping.
We believe the best way to learn is by thinking through problems yourself with just enough guidance to keep you on track. Our AI tutor provides hints that progressively guide your thinking process, helping you develop problem-solving intuition that will serve you throughout your career.
What Makes HintForge Different?
Progressive Hint System
Unlike other platforms that give you the full solution, HintForge provides 5 levels of increasingly detailed hints. Start with conceptual questions, work up to pseudocode structures, and only get specific implementation details when you need them.
AI-Powered Pattern Recognition
Our AI automatically identifies algorithmic patterns in problems (Two Pointers, Dynamic Programming, Sliding Window, etc.) and tracks which patterns you need more practice with.
Detailed Code Analysis
Submit your solution and get comprehensive feedback on correctness, time/space complexity, potential bugs, edge cases, and optimization suggestions—all without judgment.
Progress Tracking
Keep track of all problems you've solved, see which patterns you're strong in, and identify areas that need improvement. Your learning journey is saved and always accessible.
100% Free
No subscriptions, no hidden costs, no premium tiers. HintForge is completely free to use for everyone. We believe quality education should be accessible to all.

Our Philosophy
Learning by thinking, not by copying. We designed HintForge to prevent "solution dumping" where students just copy answers without understanding. Our progressive hint system forces you to engage with the problem at each step.
Pattern recognition over memorization. The key to acing coding interviews isn't memorizing 1000 problems—it's recognizing the 20-30 common patterns and knowing when to apply them. HintForge helps you build this pattern recognition skill.
Personalized learning path. Everyone has different strengths and weaknesses. Our progress tracking identifies which patterns you struggle with so you can focus your practice where it matters most.
Open Source & Free Forever
HintForge is free to use and will always remain free. We built this tool because we believe everyone deserves access to quality technical interview preparation, regardless of their financial situation.
Built with ❤️ by developer, for developers.
