The only desktop AI assistant built from the kernel up to stay 100% invisible to Zoom, Teams, and proctored browser tests. Hear questions, see problems, and get spoken-ready solutions streamed to you in seconds.
class Solution:
def trapRainWater(self, height: List[int]) -> int:
# [Zoom Screen Share Active — Capture Affinity Excluded]
# Target constraints: O(N) time complexity, O(1) auxiliary space
left, right = 0, len(height) - 1
left_max, right_max = 0, 0
water_trapped = 0
while left < right:
if height[left] < height[right]:
if height[left] >= left_max:
left_max = height[left]
else:
water += left_max - height[left]
left += 1
else: ..."First, I initialize two pointers at the boundaries. Because the amount of trapped water is bounded by the shorter bar, we can greedily process from the side with the smaller height, updating max boundaries as we advance inward."

Hardware & Architecture
Generic chatbots and web overlays get you flagged in the first five minutes. Crackround AI was architected from the Windows kernel to operate undetected under high-stakes technical scrutiny.
The Problem:
Other tools trigger red flags on Zoom, Google Meet, Teams, or browser tab-sharing because they show up on screen recordings, window trackers, and proctored canvas snapshots.
Our USP:
Built with native Windows Display Affinity (WDA_EXCLUDEFROMCAPTURE). Share your entire desktop screen, and Crackround AI remains completely invisible to the capture buffer.
Key Perks:
> VS Code - Active
> Terminal: git status
> Clean desktop render
✓ Zero capture artifacts detected
def findMedianSortedArrays(nums1, nums2):
"Binary search on the smaller array for O(log(min(m,n)))"
✓ Crystal-clear live assistive readout
Captures direct digital PCM from Zoom/Teams without microphone echo
Auto-separates your voice to prevent AI from responding to yourself
The Problem:
Manually typing out questions while maintaining natural eye contact is impossible, awkward, and a dead giveaway on webcam.
Our USP:
Dual-channel WASAPI capture listens directly to your system sound output and microphone simultaneously, separating interviewer speech from your remarks with surgical precision.
Key Perks:
The Problem:
HackerRank, Codility, Karat, and LeetCode disable clipboard copy-pasting, and system design diagrams can't be explained via audio transcription alone.
Our USP:
Press Alt+C to drag-select or full-capture any problem statement, code snippet, or complex system design architectural diagram instantly.
Key Perks:
Problem: Minimum Window Substring
Given two strings s and t of lengths m and n respectively, return the minimum window substring of s such that every character in t is included in the window...
Time: O(m + n) · Space: O(m + n) · All edge cases covered
Tailored Response Tuning:
Every code and system design solution is strictly synthesized using the company's designated technology stack, avoiding generic pseudocode or outdated framework iterations.
The Problem:
Generic AI models output generic code in whatever random language or framework they default to, which immediately signals a lack of domain expertise for senior roles.
Our USP:
Upload any massive Job Description (PDF, DOCX, TXT) with zero character limits. Crackround extracts seniority level, architectural requirements, and dialect quirks.
Key Perks:
The Problem:
Standard AI outputs robotic essays, disclaimers, or excessive conversational fluff that you cannot read out loud naturally in real-time without sounding artificial.
Our USP:
Strict interview formatting engineered for live conversation. You receive production-grade optimal code first, followed immediately by a line-by-line conversational script to speak aloud.
Key Perks:
def maxProfit(prices):
min_price, max_profit = float('inf'), 0
for price in prices:
min_price = min(min_price, price)
max_profit = max(max_profit, price - min_price)
return max_profit🗣️ "Here's how I think about this: We maintain a running tracking variable of the lowest buying price seen so far."
🗣️ "In a single pass: We calculate potential profit against that minimum price and update our global max profit, giving us clean O(N) time and O(1) space."

Proven In Production
Rahul K.
L5 Software Engineer @ Google
"I froze during my last system design round. With Crackround AI running in the background, the dual-channel loopback caught the architecture bottlenecks before I even started speaking. Google offer secured."
Priya S.
Senior PM @ Microsoft
"The spoken-ready format is the killer feature. Standard ChatGPT gives huge paragraphs you can't read out loud. Crackround AI gives you natural, conversational STAR points instantly."
Arjun M.
Staff Backend Engineer @ Meta
"WDA_EXCLUDEFROMCAPTURE works flawlessly. I shared my entire secondary screen on a 90-minute live coding round on BlueJeans/Chime. Not a single trace of the overlay. Total stealth."
