AI Coach · Always On Top
A solo coding practice coach that floats over your screen while you work LeetCode and HackerRank problems — nudging your thinking, flagging bugs before you hit run, and explaining what went wrong when you do.
Free 14-day trial · No credit card required · Windows coming soon
How It Works
01
Paste in any LeetCode or HackerRank problem. CodeWhisper reads it and gets ready to coach.
02
Ask for a hint, or just start coding — CodeWhisper flags likely bugs and edge cases as you go, and nudges your thinking with questions and patterns.
03
When you run into an error, CodeWhisper explains what went wrong in plain language. Walk away knowing why the solution works, not just what it is.
Features
Nudge → pattern → code skeleton → near-complete solution. Clicks the same level twice? Goes deeper, not in circles.
CodeWhisper watches your code as you write it and flags likely bugs and unhandled edge cases before you hit run.
When your code fails, CodeWhisper reads the output and explains what went wrong — no more parsing stack traces alone.
Click ✓ Solved when LeetCode accepts your answer. Saved to history with a green check so you can track your wins.
Floats over your browser while you code. No alt-tabbing, no distractions — just guidance when you need it.
Session history highlights which problem types and bug patterns you keep hitting, so you know exactly what to drill next.
Every problem you've worked through is saved. Reload any session and pick up exactly where you left off, hint level and all.
10 built-in patterns with templates — sliding window, two pointers, BFS/DFS, dynamic programming, and more.

FAQ
No — CodeWhisper is built for solo practice only. It's not designed for, and shouldn't be used during, any real, proctored, or interviewer-observed session.
No. Screen capture and OCR happen entirely on your device. Nothing is sent to our servers except your coaching messages.
Any text-based problem — LeetCode, HackerRank, Codewars, or plain text. Just paste it in or use Screen OCR to capture it automatically.
You keep access until the end of your billing period. No questions asked.
