What it does

Automated spaced repetition queue for LeetCode, Codeforces, GFG, HackerRank, and CodeChef. Never forget what you solved. Recall brings old problems back at the right time, helping you turn daily problem solving into long-term retention.

Automated spaced repetition queue for LeetCode, Codeforces, and DSA. Revisit questions right before you forget them, so you remember patterns in your interviews.

You solve a problem today and forget it next week. Recall reminds you to revisit questions right before you forget them, so you remember patterns in your interviews. 2 to 3 problems, automatically selected by your spaced repetition queue. Rate your confidence in one click, and Recall recalibrates the interval so you retain patterns effortlessly. Add any problem from LeetCode, Codeforces, GFG, HackerRank, or CodeChef. Title, difficulty, and topic fill in automatically. Recall assigns your first revision in 3 days. After that: 7, 14, 30. The interval adapts to your recall confidence. Open Daily Revision. Mark each problem Clean, Shaky, or Struggled. The algorithm adjusts. Your streak builds.…from recallx.tech

    I've been working on Recall for a while now, it had some initial traction in the beginning which has since died down now. I am facing the inevitable question of whether to continue with the project. I just put out a new release and it would be helpful to get advice from the community on what they think of the idea and my implementation.

    As you solve LeetCode questions, you can mark them as hard, medium, or easy. The tool will then recommend questions you should review based on (1) how hard the question was for you and (2) how much time has passed since you last reviewed it. I'd recommend normally attempting LeetCode problems and just marking them as hard, medium, or easy for you at first so the tool knows which problems to recommend you review!

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
