Your data never leaves your machine
No signup. No login. No account. No cloud database. Everything stays on your laptop — we literally cannot access your data even if we wanted to.
Zero Signup, Zero Login
No email address. No password. No account creation. Pay via Razorpay, get your license key instantly on screen, paste it in — done. We never ask who you are.
No Server-Side Database
We don't store your prompts, answers, transcriptions, or interview data on any server. There is no user database. Our backend only validates license keys — nothing else.
API Keys Stay on YOUR Machine
Your Gemini API key, Deepgram API key, and any AI credentials are saved in a local .env file on your hard drive. They are sent directly from your machine to Google/Deepgram — our servers never see them.
Resume & Context Stay Local
Your resume text, custom Q&A cheat sheets, and all interview context files live in your local app directory. They are injected into AI prompts client-side — never uploaded, synced, or stored remotely.
Zero Telemetry & Analytics
No Google Analytics. No Mixpanel. No Sentry. No crash reporters. No usage tracking of any kind. GhostCanvas makes zero outbound connections except your chosen AI APIs and optional update checks.
Bring Your Own AI Keys
Use your own free-tier API keys from Google AI Studio and Deepgram. You control the AI providers, billing, and rate limits. No middleman, no proxy, no markup. Direct client-to-provider communication.
The privacy promise: we can't see your data — by design
GhostCanvas has no user accounts, no cloud storage, and no data pipeline. Your API keys, resume, cheat sheets, interview transcriptions, and AI answers exist only on your local hard drive. Even if our servers were compromised, there is nothing to leak — because we never had your data in the first place.
Built for real interview scenarios
From technical coding rounds to system design and behavioral screens — GhostCanvas adapts to any interview type.
Technical Coding Interviews
GhostCanvas captures your screen in real time and reads coding problems as they appear. Gemini AI generates step-by-step solutions — including optimal code, time complexity, and edge cases — so you walk through your answer confidently.
Behavioral and HR Interviews
Upload your resume and custom Q&A cheat sheets. GhostCanvas transcribes the interviewer's voice, then matches each question against your prepared answers so you respond naturally, every time.
System Design Rounds
GhostCanvas reads diagrams and whiteboard content from your screen, then feeds you relevant talking points — distributed systems patterns, database trade-offs, and API design recommendations — in real time.
Mock Interview Practice
Use GhostCanvas during mock interviews to build confidence. Voice AI transcribes questions, the AI generates suggested answers — like having an invisible coach whispering tips in real time.
Frequently asked questions
Everything you need to know about GhostCanvas.
What is GhostCanvas?
GhostCanvas is an AI interview assistant for Windows. It uses real-time screen capture, voice transcription (Deepgram Nova-3 / Whisper), and Google Gemini AI to generate contextual answers during live interviews. It runs invisibly — no one but you knows it's there.
Is GhostCanvas free?
GhostCanvas is ₹499 for a lifetime license — a one-time payment. No monthly subscriptions, no hidden fees, no signup or account creation required. You get your license key instantly after payment and use it forever.
What happens after payment?
Immediately after payment, your license key appears on-screen and is also sent to your email. Activate it in the app, and you have lifetime access — including all future updates.
Can I get a refund?
Yes. We offer a 7-day no-questions refund policy. If GhostCanvas doesn't work for you within 7 days of purchase, contact us via the support link and we'll refund in full — no questions asked.
How does the invisible mode work?
GhostCanvas disguises itself as a system process — no dock icon, no console window. A floating overlay shows AI answers visible only to you. Press Alt+V to toggle visibility instantly.
Is my data safe and private?
Absolutely. GhostCanvas has zero signup — no email, no account, no login. Your API keys (Gemini, Deepgram), resume, and Q&A cheat sheets are stored exclusively on your local machine and never transmitted to our servers. We have no database of user data. With Whisper (local mode), no audio leaves your device at all. Deepgram streams audio securely and does not store it. There is zero telemetry, zero analytics, and zero tracking of any kind.
What are the system requirements?
Windows 10 or 11 (64-bit), 4 GB RAM, 500 MB disk space, and an internet connection for Gemini AI. For local Whisper transcription, Python 3.9+ is also required.
