Show HN: ReviLearn – Remember what you read online

A few years ago, I took the popular "Learning How to Learn" course, which introduced me to spaced repetition and active recall. It completely changed how I approached mastering technical concepts and coding problems.

But I struggled to apply it consistently: I could save LeetCode problems, articles, and docs in bookmarks, but I rarely reviewed them at the right time — and ended up forgetting most of them.

So I built ReviLearn, a free Chrome extension that lets you:

- Save any web page or coding problem - Rate its difficulty (1–4), so it knows when to remind you - See a calendar of upcoming revisions - View an analytics dashboard with streaks and mastery breakdown - Get daily notifications to keep up your routine - Categorize topics (e.g., "DP", "System Design", "JavaScript") - Export everything to CSV if needed

I just redesigned the UI to make it much more modern and motivating. I kept it completely free — no paywalls.

I’d love feedback from the HN community: What features would help you actually stick to reviewing? How do you currently manage your learning revisions?
