Real Dashboard Visualizations
These are actual components from your dashboard — same visuals, demo data for showcase. All widgets below are also live from the extension.
Everything You Need to Dominate Coding Interviews
From automatic attempt tracking to spaced repetition, our Chrome extension gives you the tools to transform random grinding into the strategic mastery that gets you hired at companies you actually want to work for.
Science-Backed Spaced Repetition
Never waste time on problems you've already mastered. Our intelligent scheduling system tracks every solution and automatically resurfaces problems at the perfect moment for long-term retention.
Problems are organized into three clear queues:
- NEW PROBLEMS - Fresh challenges you haven't attempted yet
- DUE TODAY - Problems scheduled for reinforcement right now
- SCHEDULED - Future reviews planned for optimal retention
Stop grinding blindly. Start building lasting mastery.

And That's Not All
Beyond visual progress tracking and spaced repetition, we've packed even more tools to accelerate your interview prep:
Automatic Attempt Tracking
Every LeetCode submission automatically saved with full context: your code, timing, and outcome. Never lose progress again.
Analytics Dashboard
Deep insights into your coding patterns. Track progress across difficulty levels, topics, and time. Visualize your growth with beautiful charts.
Smart Tagging & Lists
LeetCode's built-in tags automatically tracked. Pre-loaded curated lists (Blind 75, NeetCode 150) to focus your grinding.
Time Tracking
Accurate time measurement for each problem. Understand how long you actually spend, identify time sinks, improve efficiency.
Notes & Surveys
Capture insights after every solve. Quick surveys help track confidence, identify weak spots, and guide your learning path.
From Random Grinding to Strategic Mastery
LeetCode grinding without tracking is like running in the dark. You solve hundreds of problems but forget most within weeks. No way to identify weak spots, no system for retention, just endless repetition hoping something sticks.
HashTry changes everything. Every attempt is captured automatically. Spaced repetition ensures you review problems exactly when you need them. Deep analytics reveal your true weak spots. Transform your LeetCode journey from random grinding into a strategic mastery system.
Without HashTry
- Forget solutions after 2 weeks, solve same problems multiple times
- No idea what to review or when - just random grinding
- Can't identify weak spots, waste time on wrong problems
- Walk into interview hoping you remember enough
With HashTry
- Every solution automatically saved - review exactly when needed
- Spaced repetition schedules reviews for maximum retention
- Analytics reveal true weak spots - focus where it matters
- Walk into interview knowing exactly what you've mastered

Frequently Asked Questions
Everything you need to know about HashTry and how it helps you master LeetCode.
Do you unlock LeetCode Premium features for free?
NO. We do NOT provide LeetCode Premium features for free.
We don't unlock premium-only problems, company tags, or video solutions. We don't bypass LeetCode's paywall in any way.
What we DO: Track YOUR attempts on problems you can already access. Add spaced repetition and analytics for YOUR progress.
HashTry complements LeetCode, we don't replace it.
Does this violate LeetCode's Terms of Service?
NO. We do NOT violate LeetCode's ToS.
We only read what's already loaded in your browser as you solve problems. Everything happens client-side - no server scraping, no API requests to LeetCode.
Personal tracker for YOUR data only.
What data do you collect?
Your LeetCode solving history:
• Your code solutions and submission status (Accepted or Failed)
• Problem details (title, difficulty, LeetCode's tags)
• Programming language used
• Time spent solving
• Date and time of submission
• Your survey answers (11 questions including notes)
Nothing else. No browsing history, no other users' data. Stored securely, never sold.
Can I use HashTry for free?
Yes! Get full access to all PRO features free for 14 days. No credit card required. After the trial, continue with PRO for $6/month or keep using in read-only mode to view your existing data.
How does automatic attempt tracking work?
The Chrome extension monitors your LeetCode submissions in real-time. Every time you submit code, we automatically capture your solution, timing, and outcome (Accepted/Wrong Answer/etc). No manual logging required.
What is spaced repetition and why does it matter?
Spaced repetition is a scientifically proven learning technique where you review material at increasing intervals. Our system schedules problem reviews exactly when you need them to build long-term retention, not just short-term recall.
Does this work with all LeetCode problems?
Absolutely. HashTry tracks all problem types on LeetCode - Easy, Medium, and Hard. It works with every programming language LeetCode supports.
Is my code and data secure?
Your data is stored securely with industry-standard encryption practices. All connections use HTTPS. Your code and solutions are private to your account only.
