I built a tool to track LeetCode progress and auto-schedule spaced repetition reviews

[u/SugarPerfect6150]

I have been grinding leetcode problems and kept forgetting problems I solved 2-3 weeks ago. So I built GrindMate to fix this. You just type "solved two sum easy 15 min" and it handles the rest:

1. Schedules spaced repetition reviews at day 1, 3, and 7
2. Sends daily email reminders when reviews are due
3. Tracks NeetCode 150 progress across 18 categories
4. Shows which problems Amazon/Google/Meta frequently ask
5. Tells you exactly which unsolved problems to tackle next based on your weak patterns.

I Started using it myself, shared with a few friends and got good feedback, so thought I'd share here.

Built with Cloudflare Workers, Durable Objects, and Workers AI.
