Ever accidentally seen your old solution and lost the chance to truly re-solve a problem? Tired of wondering how much focused time you're actually spending on coding practice?
CodeBlur is a Chrome Extension (Manifest V3) designed to protect your coding practice from unintentional spoilers and help you measure your real effort. Whether you're tackling a LeetCode challenge or GeeksforGeeks challenge, CodeBlur keeps solved solutions hidden until you choose to reveal them, tracks how long you actively spend on the site, and counts how many times you hit Run or Submit.
Why Install CodeBlur?
- Prevent Spoilers. Have you ever revisited a problem only to accidentally see the old solution and lose the chance to solve it again? CodeBlur automatically blurs your previously solved code so you can reattempt problems with a fresh mind.
- Measure Real Focus. CodeBlur tracks your total active time spent on LeetCode—not just time the tab is open, but time when you're actually active. This helps you understand how much focused effort you're putting in across sessions.
- Track Your Workflow. Curious how often you click "Run" or "Submit" before getting it right? CodeBlur logs every Run and Submit click so you can reflect on your problem-solving process and iterations.
Key Features:
1. Auto‑Blur Solved Code
- Detects when a problem is solved on LeetCode or GeeksforGeeks.
- Automatically blurs the solution area to prevent spoiling yourself.
2. Focus Timer
- Tracks total time you are actively engaged on the LeetCode platform.
- Helps identify productive coding hours.
3. Run/Submit Counter
- Increments each time you press "Run" or "Submit."
- Reveals how many iterations it takes you to solve problems.
4. Total Effort Tracker
- Displays total active time you've spent across LeetCode sessions.
- Great for weekly or monthly progress tracking.
5. Privacy‑First
- All data stays local in your browser—no external servers, no tracking, no account needed.
Usage Example:
Imagine you're practicing on LeetCode. CodeBlur starts tracking your active time as soon as you engage with the site. You press "Run" four times and "Submit" twice—CodeBlur records those. After solving the problem, your solution is automatically blurred to prevent spoiling future practice. You can now revisit the problem later and truly test your recall and logic.
How It Works:
- Blur Logic: Injects CSS overlays to hide solved code sections.
- Timer: Tracks active browser engagement, not just open tabs.
- Counters: Listens for Run and Submit button clicks and updates local stats.
- Lightweight & Efficient: Built using Chrome Manifest V3 for security and performance.
- Compatible with: LeetCode and GeeksforGeeks coding problem pages.
Get Started:
1. Install CodeBlur from the Chrome Web Store.
2. Open any LeetCode or GFG problem page.
3. Solve problems as usual—blurred answers, timer tracking, and button counts happen in the background.
4. Revisit old problems without getting spoiled and track your growth over time.
Key Questions to Ask:
- Are you solving the problem, or just remembering the answer?
- How much focused time are you really putting into coding?
- What if you could measure your real effort without changing your workflow?
If these matter to you, install CodeBlur today and start building better coding habits.
