Built for real interview scenarios
Whether you are preparing for a technical coding interview, a behavioral screen, or a panel discussion, GhostCanvas adapts to your situation with AI-powered intelligence.
Technical Coding Interviews
GhostCanvas captures your screen in real time and reads coding problems, algorithms, and data structures as they appear. Gemini AI analyzes each question and generates step-by-step solutions — including optimal code, time complexity, and edge cases — so you can walk through your answer confidently.
Behavioral and HR Interviews
Upload your resume and prepare custom Q&A cheat sheets tailored to your experience. GhostCanvas transcribes the interviewer voice using Deepgram Nova-2, then matches each question against your prepared answers so you respond naturally and on point every time.
System Design and Architecture
System design interviews require drawing diagrams, explaining trade-offs, and discussing scalability. GhostCanvas reads the screen to understand diagrams and whiteboard content, then feeds you relevant talking points — distributed systems patterns, database choices, and API design recommendations — in real time.
Mock Interview Practice
Use GhostCanvas during mock interviews to build confidence. The voice AI transcription captures the interviewer questions, while the AI generates suggested answers in real time. It is like having an interview coach whispering tips — except it is an invisible assistant running locally on your Windows machine.
Frequently asked questions
Everything you need to know about GhostCanvas, the free AI interview assistant.
What is GhostCanvas?
GhostCanvas is a free, open-download AI interview assistant for Windows. It uses real-time screen capture, voice transcription powered by Deepgram Nova-2 and OpenAI Whisper, and Google Gemini AI to generate contextual answers during live interviews. It runs invisibly on your machine — no one but you knows it is there.
Is GhostCanvas really free?
Yes. GhostCanvas offers a free lifetime license with no credit card required, no subscriptions, and no hidden fees. During our launch period, you can download the full product and get a license key instantly. The only costs are your own API keys for Gemini, Deepgram, or Whisper — all of which offer generous free tiers.
How does the invisible mode work?
GhostCanvas disguises itself as a system process — the window title and process name are changed to blend in. There is no dock icon and no console window. A small floating overlay displays AI-generated answers — visible only to you on your screen. You can toggle visibility instantly with Ctrl+Shift+V, making GhostCanvas completely disappear from view.
Which AI models does GhostCanvas use?
GhostCanvas is powered by three industry-leading AI systems. Google Gemini handles screen analysis and real-time answer generation. Deepgram Nova-2 provides cloud-based voice transcription with low latency. OpenAI Whisper offers an alternative for fully local, offline speech-to-text transcription — no data ever leaves your machine.
Is my data safe and private?
GhostCanvas runs entirely on your local machine. All API keys are stored locally and never sent to our servers. If you use Whisper for transcription, no audio data leaves your device at all. For cloud transcription via Deepgram, audio is streamed securely over WebSocket and not stored. Your interview data stays with you.
What are the system requirements?
GhostCanvas requires Windows 10 or Windows 11 (64-bit), at least 4 GB of RAM, and 500 MB of free disk space. An internet connection is needed for Gemini AI and Deepgram transcription. If you choose Whisper for local transcription, you will also need Python 3.9 or later installed on your machine.
