Hi Codeforces!

Are you struggling with practicing effectively? Maybe you are having issues with using key insights from previous problems you solved in new problems? (Note: multiple top problem solvers like Geothermal (CF international grandmaster, top 0.02%) recommend reflecting on key ideas/observations 💡 after solving problems in order to be able to tackle new problems.)

Thus, I have created this platform called 🌠 Starlight Problem Solving to help people improve:

• 🙋 You can share and view a summary of insights (thanks to AI) on over 20,000 problems (Codeforces, AtCoder, DMOJ, etc). This allows you to see new important insights you may be missing on finding.
• 🔍 You can also view similar problems based on insights (thanks to AI) so if you couldn't solve a problem, you can now find similar problems to allow you to master the insight(s) you struggled with.
• 🤔 You can also see hints to spend more time with hands on problem solving.
• 🏗 In the future, we hope to create an AI to predict key insights problems (including ones with no insights in this database) and use AI to summarize the key insights needed to achieve a certain level (e.g. USA computing olympiad gold, codeforces rating 1900) since problem solving skills in addition to algorithms is needed.

If this sounds like it would be useful, please consider joining the website. Let as many people know as possible (links of text to copy in share the message) as we likely NEED data on MANY TYPES of problems. Use the JOURNAL FEATURE which stores all the insights of problems you solved!

We are working to add the feature to help import your spreadsheets of insights for your practice to the journal to make it more convenient!

30 day problem solving challenge (win up to $100)

We're doing a 30 day problem solving challenge where one lucky winner will get an Amazon gift card worth up to $100. The prize depends on participation, so please share this challenge. To qualify, you must solve at least 15 problems and post at least one insight/hint for each. More information here: https://starlightps.org/about/challenge/.

We are working to add the feature to help import your spreadsheets of insights for your practice, so we may extend the deadline.
