DSA Interview AI Solver: Screenshot Any LeetCode Problem for Instant Code

The Coding Round Problem

You're 10 minutes into a coding interview. You see a dynamic programming problem. Your mind goes blank. The timer is running.

This is exactly where Ghostly AI's screen analysis changes the outcome.

How Screen Capture Analysis Works

1. Press the screenshot hotkey (configurable, default: Ctrl+Shift+S)
2. Draw a selection around the coding problem on your screen
3. Ghostly sends the image to your chosen AI model (Gemini, GPT-4o, Claude)
4. Within 3–5 seconds, you get a full structured response

The AI Response Format

For every coding problem, Ghostly AI returns:

🧠 Approach: "Use sliding window technique. Maintain a window of size k, subtract the element leaving and add the one entering..."

⏱ Complexity:

• Time: O(n)
• Space: O(1)

🔍 Edge Cases:

• Empty array
• k larger than array size
• All negative numbers

💻 Clean Code:

def maxSumSubarray(nums, k):
    window_sum = sum(nums[:k])
    max_sum = window_sum
    for i in range(k, len(nums)):
        window_sum += nums[i] - nums[i-k]
        max_sum = max(max_sum, window_sum)
    return max_sum

What Problem Types It Handles

Pro Tips for Better Results

Include the full problem: Ensure your screenshot captures the complete problem statement, constraints, and examples.

Add context in chat: After the initial response, use the chat panel: "Now optimize it further, the input can be up to 10^7 elements."

Ask for the simplest solution first: Explicitly ask "give me the brute force first, then the optimal" so you can explain progression naturally.
