Forgetting LeetCode solutions after days — auto SRS recall with zero-card work

Forgetting LeetCode solutions after days — auto SRS recall with zero-card work targets a $2.6B = 26M software developers x $100/year average subscription total addressable market with medium saturation and a year-over-year growth rate of 12% — steady growth in coding bootcamps, online interview prep and dev upskilling.

Key trends driving demand: LLMs for code -- better automatic summarization and synthesis enables auto-generated recall cues and tests.; Remote hiring growth -- more candidates preparing remotely increases demand for efficient prep tools.; Spaced-repetition adoption -- learners are adopting evidence-backed methods (SRS + microlearning) for durable retention.; Browser-extension + OAuth ecosystems -- easier capture of user activity from platforms like LeetCode and GitHub..
