FOR LEETCODE

The AI copilot built for LeetCode-style interviews

You screenshot the problem. Interview Helpers streams the solution with commented C++11, Python, or Java code, complexity analysis, and an explanation of why it works — from a stealth overlay hidden from screen share. It runs on top of your IDE with click-through transparency so it never blocks the terminal.

Hotkey screenshot

Ctrl+1 captures your current screen, attaches it to the AI prompt, and streams an answer. No Alt-Tab, no paste, no upload delay.

Full solutions in seconds

Get a one-paragraph summary, chosen data structure, correctness explanation, fully commented C++11 / Python / Java code, and time + space complexity — all in one response.

Multi-screenshot batching

Take 2, 3, or 5 screenshots of a long problem in quick succession — they auto-batch into one turn and the AI addresses each in order.

Follow-ups keep context

Prior screenshots persist in the session. Ask "explain step 3 of Screenshot 2" and the AI still sees the image.

Choose your model

Switch between GPT-5.6 Terra (fast), GPT-5.6 Sol (premium), Claude Sonnet 5, or Claude Opus 5 in one click depending on how tricky the problem is.

Stealth by default

Hidden from Windows taskbar. Hidden from Zoom, Google Meet, and Teams screen share. Click-through transparency so the overlay never blocks your IDE.

How the LeetCode flow works

  1. Install the Windows app: 30-second NSIS installer, no admin required. Grab the .exe.
  2. Sign in with the same account you signed up with here. The trial gives you 10 free messages and 5 minutes of speaker mode.
  3. Open the LeetCode problem in your browser next to your IDE.
  4. Hit Ctrl+1 — the whole visible screen is captured and streamed to the AI. The user bubble appears in the overlay immediately with a thumbnail; the answer streams in below.
  5. Ask a follow-up in the input box — "show me a two-pointer version" or "what if the array is sorted" — and the AI still has the screenshot in context.
  6. Snap another screenshot mid-answer if you missed a part of the problem — the in-flight answer is cancelled and merged with the new capture into one fresh answer covering both.

Common LeetCode question types it handles

• Arrays & hashing (Two Sum, Group Anagrams, Longest Consecutive)

• Two pointers (Container With Most Water, 3Sum)

• Sliding window (Longest Substring Without Repeating)

• Stack & queue (Valid Parentheses, Daily Temperatures)

• Binary search (Search in Rotated Sorted Array)

• Linked list (Reverse, Merge Two Sorted, Cycle Detection)

• Trees (BFS, DFS, LCA, Serialize / Deserialize)

• Tries (Word Search II, Autocomplete)

• Heap / priority queue (Top K, Merge K Sorted)

• Backtracking (Combination Sum, Word Break, N-Queens)

• Graphs (Number of Islands, Course Schedule, Dijkstra)

• Dynamic programming (1D, 2D, state machine)

• Greedy (Jump Game, Gas Station)

• Intervals (Merge Intervals, Meeting Rooms)

• Bit manipulation, math, and everything else
