Question 1

Does it work on Mac and Windows?

Accepted Answer

Yes. GhostApp by TsarChat.com is built natively for ultimate performance and low overhead. We offer dedicated, fully optimized binaries for macOS (Apple Silicon M1/M2/M3 and Intel) as well as Windows 11+.

Question 2

Which AI models do you support, and can I switch between them mid-session?

Accepted Answer

You get access to the full frontier: Claude (Opus, Sonnet, Haiku), OpenAI GPT, Google Gemini (Pro, Flash, Flash Lite), Groq, and Grok. You can switch models in real time during a meeting without reloading — use Claude Sonnet for tricky coding logic, GPT for polished behavioral answers, and Groq when you need a response in under 100 milliseconds. We update to the latest frontier models within 48 hours of release to maintain elite performance and reliability.

Question 3

How fast are the responses in real time?

Accepted Answer

Most queries exhibit latency under 100 milliseconds. Because GhostApp by TsarChat.com is a highly optimized native application (not an Electron app or a browser extension), there is no Chromium overhead between your input and the model. For lightning-fast follow-ups where every second counts, the Groq pathway delivers answers faster than you can finish reading the question.

Question 4

Does it work alongside common video conferencing apps?

Accepted Answer

Yes. GhostApp by TsarChat.com operates as a process running at the operating system layer rather than a browser extension, so it operates independently of major video conferencing apps. You are responsible for ensuring your use of any third-party platform complies with that platform’s Terms of Service, your employer or institution’s policies, and any applicable recording-consent laws.

Question 5

Will it trigger my corporate VPN or Antivirus?

Accepted Answer

GhostApp by TsarChat.com features robust stealth capabilities designed to remain completely unobserved by standard screen-capture and recording tools, and it operates with a minimal system footprint. Behavior on any specific corporate VPN, endpoint-management agent, or antivirus product depends on that product’s configuration and is outside our control. Use of GhostApp by TsarChat.com on a managed device is your responsibility under your employer’s acceptable use policy; we do not warrant that the application is, or will remain, undetectable by any specific third-party monitoring tool.

Question 6

Is my screen or audio data stored on your servers?

Accepted Answer

No. Screen captures and audio are processed locally on your device and sent directly to your chosen LLM provider for inference — they never touch our servers. All sensitive data on-disk is encrypted. We don’t log, track, or retain the content of your sessions.

Question 7

Can I use my own OpenAI or Anthropic API keys?

Accepted Answer

Yes. We fully support Bring Your Own Key (BYOK). You can easily plug in your own API keys for OpenAI, Anthropic, or other supported models. Your keys are encrypted and stored locally on your machine — we never log, track, or store your credentials on our servers.

Question 8

How long is the free trial, and what’s limited?

Accepted Answer

Every signup gets a 14-day free trial — no credit card required. The trial is a demo, not a free tier: stealth mode drops randomly, sessions are capped at 15 minutes, and you get ~30 AI credits. It’s designed to let you verify the product, not to carry you through a real meeting. For actual interview use, upgrade to a paid plan.

Question 9

How many devices can I use with one subscription?

Accepted Answer

Two devices by default (e.g. your laptop + a backup machine). Higher device counts are available on specific plans. If you try to sign in on a third device, you’ll get a prompt to remove an existing device from your Settings dashboard first. Devices that go inactive for 7+ days are auto cleaned so you rarely have to manage this manually.

Question 10

What payment methods do you accept?

Accepted Answer

All major credit and debit cards (Visa, Mastercard, Amex, Discover), plus Apple Pay and Google Pay — all processed through Stripe. We never see or store your full card number; only the last 4 digits, brand, and expiry are kept for receipts and billing.

Question 11

Can I cancel anytime? What’s your refund policy?

Accepted Answer

Yes — cancel anytime with one click from your Settings page. Your access continues through the end of the period you already paid for; there’s no long-term lock-in. Each plan is a fixed-duration one-time purchase (1/3/6 months, no auto renewal). To move to a different plan, let your current one run out (or cancel it now) and buy the new plan fresh from the pricing page. If something’s wrong, email support — we’ll take care of it.
