Organize coding problems across platforms into Google Sheets. Auto-populates difficulty and normalized tags. Transform your coding practice with CodeQuest 🚀 — the ultimate problem solving companion that saves, organizes, and tracks problems from coding platforms — directly into your personal Google Sheet. ❓Why CodeQuest? Stop copying URLs and juggling bookmarks. CodeQuest captures each problem with consistent metadata so you can focus on solving and improving. ⚡ Key benefits: — One-click save with auto-populated metadata: Title, URL, platform, difficulty, and suggested tags are filled automatically. — Google Sheets integration: Problems sync to your personal sheet immediately so you can sort, filter, and build practice queues. — Tag normalization: Equivalent tags (e.g., “bfs”, “BFS”, “breadth-first search”) map to one canonical tag for consistent organization. — Custom difficulty mapping: Set your own easy/medium/hard thresholds (for Codeforces and CodeChef). — Fast and lightweight: Save problems without note/explanation in under 3 seconds. — Privacy-first: No tracking; all data is stored only in your Google Sheet. 🛠 How it works (2 minutes): — Install CodeQuest from the Chrome Web Store. — Connect your Google Sheet once from the Options page. — On any supported coding site, click the CodeQuest icon → Save Problem. The problem is logged automatically. 💡 Pro Tips: — Enable chip-style dropdowns in Google Sheets: Data → Data validation → Choose range (e.g., F2:F1000) → Display style: “Chip” → Allow multiple selections. — Use sheet filters and sorting to create custom practice queues (e.g., by pattern, tag or difficulty). 🔒 Privacy & Security: — Zero data collection or tracking — All information stored in your personal Google Sheet — No premium subscriptions or hidden costs
Codeforces Rating-Based Heatmap
This Chrome extension enhances Codeforces user profiles by adding a rating-based heatmap that visually represents problem-solving activity. Unlike the default heatmap, which only counts the number of problems solved per day, this extension highlights each day based on the difficulty of the hardest problem solved. KEY FEATURES: 🔹Accurate Rating Heatmap: The heatmap color on a given day represents the maximum rating of a problem solved that day. 🔹Quick Insights: Hovering over any day in the heatmap shows a tooltip displaying detailed information about the problems solved on that day. The tooltip includes: • Problem Name • Problem Rating • Direct Link to the Problem • Indicator if the problem is a duplicate 🔹 Multi-Year Support: Users can analyze their performance across multiple years, allowing for a comprehensive view of their progress over time.
CF-Predictor

But if you are stuck with any problem then you can view the tags by clicking on Show All Tags button. The extension also includes a shortcut to go to the Contest Standings directly. This extension is very helpful while practicing problems on Codeforces as it helps you to know the rating of the problem without explicitly knowing the tags associated with it. How to use : 1. Install the extension. 2. Turn off [ Show tags for unsolved problems ] option in the Problemset page of codeforces. 3. Open any Codeforces problem and it will show the problem rating. *NOTE* The extension does not work when the Codeforces API is down. *NOTE* The extension does not work with problems that do not have a problem rating. [ Screenshots for all the cases are attached ] UPDATE 1.0.1 Now you will be able to visit the Contest Standings from the problem page itself with the click of a button. UPDATE 1.0.3 Fixed issues with problem parsing. UPDATE 1.0.4 New feature to Show All Tags for a problem.
CF Analytics
CF Analytics Chrome extension improves the Codeforces profile webpage to include statistics of problems solved by the user. The ‘Problem Rating’ graph is a bar chart showing problems solved for each problem rating. The ‘Tags Solved’ graph is a doughnut chart displaying tags solved across any problem and also lists a count for each tag. The ‘Unsolved Problems’ shows a count of all problems attempted with not correct verdict and also lists them. The extension communicates only with the Codeforces API and runs entirely on the browser.
