Plans

• All LeetCode pattern lessons, with tested Go code and visualizers
• The 150-problem roadmap with a hint ladder and a Go solution for every problem
• "Which pattern?" drills, flowchart, spaced review and mock interviews

A paid tier is being considered. These are ideas, not promises: nothing here has a date or a price, and the free content above will stay free.

• More AI feedback. A larger daily allowance for feedback on your reasoning in the pattern drills.
• Progress sync. Pick up your progress on another device without exporting a backup.
• Guided system design practice. Work through a design step by step and get AI review of your answer.
• Exportable study plans. Take your roadmap plan with you as a document, beyond the calendar download.
