# Cracko — AI Interview Copilot > Cracko is a private desktop AI interview copilot for Windows and macOS. It transcribes live audio in real-time, maintains deep session context across interview rounds, and streams structured, latency-optimized answers into a floating answer window that is hidden from meeting screen shares on Zoom, Google Meet, Microsoft Teams, and Webex. Cracko operates locally on the desktop rather than as a visible browser tab or extension. It acts as an interactive coaching window to help software engineers, engineering managers, and technical professionals answer algorithmic, system design, and behavioral questions with clarity and structured thinking. ## Core Capabilities - **Real-Time Speech-to-Text Transcription:** Uses advanced low-latency speech recognition to transcribe incoming interviewer questions from system audio streams. - **Context-Aware Streaming Answers:** Maintains conversation context across the entire session, generating tailored answers based on role, target stack, and custom prompt rules. - **Screen-Capture Protected Answer Window:** Built with native OS window display affinity flags (WDA_EXCLUDEFROMCAPTURE / CGWindow sharing) so the floating answer window is excluded from screen shares and recordings. - **Coding & System Design Analysis:** Provides syntax, algorithmic complexity (Big-O time and space), architecture blueprints, trade-off comparisons, and edge-case handling. - **Customizable Session Briefs:** Users configure job role, seniority level, tech stack (e.g., Python, Go, React, Kubernetes), and answer brevity before joining the call. - **Cross-Platform Desktop Native:** Dedicated native desktop clients built for Windows and macOS. ## Use Cases - **Technical Coding Interviews:** Data structures and algorithms (LeetCode-style problems), debugging, language syntax, and complexity trade-offs. - **System Design Rounds:** High-level architecture, database trade-offs (SQL vs NoSQL), caching, microservices, load balancing, and distributed systems. - **Behavioral & Leadership Rounds:** Structuring answers using the STAR method (Situation, Task, Action, Result), leadership principles, and conflict resolution. - **Mock Interviews & Interview Practice:** Self-study coaching tool to practice answering impromptu technical questions. ## Supported Conferencing Platforms Cracko captures audio played through system audio output and works seamlessly with: - Zoom - Google Meet - Microsoft Teams - Cisco Webex - Slack Huddles - Chime and browser-based call platforms ## Product & Technology Details - **Application Type:** Native Desktop Application (Windows 10/11, macOS 12+). - **Audio Capture:** WASAPI loopback capture on Windows, CoreAudio capture on macOS. - **Security & Privacy:** Sessions are private to authenticated users. Audio processing remains isolated to the user's active session and is never injected into conferencing applications. - **Official Website:** https://cracko.in/ ## Key Resources & Documentation - [Home](https://cracko.in/): Overview of the Cracko AI interview copilot desktop application. - [Pricing & Plans](https://cracko.in/pricing): Access passes including Quick Prep Pass, Monthly Pro, and Lifetime Access. - [Frequently Asked Questions](https://cracko.in/faq): Detailed explanations of privacy, screen capture exclusion, supported platforms, and setup. - [Contact Support](https://cracko.in/contact): Support email and team inquiries. - [Privacy Policy](https://cracko.in/privacy): Audio streaming privacy, session data security, and account protection. - [Terms of Service](https://cracko.in/terms): Acceptable use policy and fair-use interview coaching guidelines.
