You solved 200 problems.
You remember maybe 30.
Chrome extension that replaces your solved counter with what actually matters.
Self-assessment after every problem → S/A/B/C/D tier grades
Spaced repetition → review what you're forgetting, skip what you know
Interview Readiness Score → one number 0–100 instead of "I think I'm ready?"

How it works
Three steps. No setup, no config, no manual logging.
Pick a list
Blind 75, NeetCode 150, Grind 169, or Combined 212. Everything revolves around your chosen list.
Solve problems
Auto-timer starts when you hit Solve. After Accepted — quick self-assessment survey. You get a tier grade: S, A, B, C, or D.
Track what matters
Interview Readiness Score 0–100, spaced repetition schedule, weak spots by topic. One dashboard, no guessing.
You forget problems.
We bring them back.
D-tier problem? Review tomorrow. S-tier? See you in two months. The system schedules reviews based on how well you actually know each problem — not how many times you've seen it.
New problems — from your chosen list, haven't attempted yet
Due today — scheduled for review right now
Scheduled — coming up, no action needed yet
Quality component — tier distribution by topic, 30% of your score
One number instead of
"I think I'm ready"
Interview Readiness Score. 0 to 100. Calculated from five real signals — not just how many problems you've solved.
Measures list completion readiness, not a guarantee of interview results.
Solve speed (improving or stalling?)
Topic coverage (are you skipping Graphs?)
Solution quality (tier grades across problems)
Consistency (grinding daily or once a month?)
Self-assessment accuracy (do you know what you know?)
Share progress, not just screenshots
Post to Twitter, drop in Discord, or send to your study group.
Stay accountable — people who share progress are more likely to keep going.

What's included
Without HashTry
- Forget solutions after 2 weeks. Solve same problems over and over.
- No idea what to review or when. Just pick random problems and hope.
- Can't tell if you're weak in Graphs or DP. Waste time grinding Arrays again.
- Walk into interview with "I think I'm ready". Spoiler: you're not sure.
With HashTry
- Tier grade after every problem. You know exactly where you stand.
- D-tier? Review tomorrow. S-tier? See you in 2 months. Automatic.
- Score shows you're weak in Graphs — so you fix Graphs, not grind Arrays again.
- Interview Readiness Score says 82. You go in confident, not hoping.

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.
Does this violate LeetCode's Terms of Service?
NO. 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.
Can I use HashTry for free?
Yes. 14 days, all features, no credit card. After that — $6 for 30 days, $11 for 60, $15 for 90. One-time purchase, not a subscription. When time runs out — read-only mode, your data stays.
What data do you collect?
Your LeetCode solving history:
• Code solutions and submission status (Accepted or Failed)
• Problem details (title, difficulty, tags)
• Programming language, time spent, date of submission
• Your survey answers
Nothing else. No browsing history, no other users' data. Never sold.
What lists are supported?
Blind 75, NeetCode 150, Grind 75, Grind 169, and Combined 212. You pick one, everything revolves around it — progress tracking, spaced repetition, Interview Readiness Score.
How does automatic attempt tracking work?
Extension watches your LeetCode submissions in real-time. Every time you submit code, it captures your solution, timing, and outcome. No manual logging.
What is spaced repetition?
You solved a problem. The system decides when you should see it again based on your tier grade. D-tier — review tomorrow. S-tier — see you in two months. You don't manage the schedule, it manages itself.
What is Interview Readiness Score?
A number from 0 to 100 based on five signals: solution quality, topic coverage, solve speed, self-assessment accuracy, and consistency. It measures your list completion readiness — not a guarantee of interview outcome.
Can I share my progress?
Yes. Three types of Share Cards — Weekly (overall progress), Daily (today's session), and Problem (single problem history). Each in two formats: 16:9 for Twitter/LinkedIn and 1:1 for Reddit/Instagram. One click to copy or download.
Does this work with all LeetCode problems?
Yes. All difficulty levels (Easy, Medium, Hard), every programming language LeetCode supports.
Is my code and data secure?
HTTPS everywhere, encrypted storage. Your code and solutions are private to your account only. We don't share or sell anything.
