Everything about Interview Assistant — pricing, how the stealth overlay works, comparisons with Final Round AI and LockedIn AI, setup, privacy, and more.
Interview Assistant is a Windows desktop application by CrackItX that runs as a stealth overlay during live video interviews. It listens to the interviewer's audio in real time and generates suggested answers using Anthropic's Claude AI. The overlay is invisible to screen capture software including Zoom, Microsoft Teams, Google Meet, and OBS.
The application captures system audio from the conferencing app and streams it to Deepgram Nova-3 for speech-to-text. After 1.5 seconds of silence, the transcribed question is sent to Claude with the user's resume and job description as context. Claude streams an answer back token-by-token, which appears in the on-screen overlay only the user can see. End-to-end latency is approximately 2.5 seconds.
Yes. Interview Assistant uses the Windows DWM SetWindowDisplayAffinity API with the WDA_EXCLUDEFROMCAPTURE flag. The operating system excludes the overlay window from any frame buffer handed to screen capture clients. The interviewer sees a normal screen share with no overlay visible.
Interview Assistant has three plans priced in Indian Rupees: Starter at ₹1,499 (15 interviews total, never expires), Pro at ₹3,999 (unlimited sessions for 3 months, renewable), and Premium at ₹7,777 (unlimited sessions for 6 months, renewable). There is no monthly or annual subscription, and nothing is charged automatically. All payments are processed via Razorpay, accepting UPI, credit and debit cards, and net banking.
No. The exclusion happens at the operating system layer via WDA_EXCLUDEFROMCAPTURE, not at the application layer. Zoom, Teams, Google Meet, OBS Studio, Windows Snipping Tool, Print Screen, and Windows Game Bar all receive a frame buffer that does not contain the overlay. Detection would require bypassing the OS-level exclusion, which the conferencing applications do not do.
Final Round AI is a subscription-based competitor at approximately $58/month for the Pro tier ($95 for Premium), supporting Windows, macOS, and web. CrackItX Interview Assistant is currently Windows-only and has no subscription: ₹1,499 one-time for Starter, or ₹7,777 for 6 months of unlimited use on Premium — less than two months of Final Round AI Pro. CrackItX also accepts INR billing via Razorpay/UPI; Final Round AI charges in USD.
LockedIn AI uses a credit-based subscription model starting at approximately $25/month, with interview minutes consumed from a credit balance. CrackItX Interview Assistant uses flat pricing with no per-minute cost or credit consumption. LockedIn AI offers a Duo feature where a human can assist live; CrackItX does not. LockedIn AI supports macOS; CrackItX is Windows-only as of 2026.
Interview Assistant uses Anthropic's Claude by default — Claude Sonnet 5 generates the answers, accessed through the Anthropic SDK with token streaming. Claude Haiku 4.5 is used only for the optional quick one-line answer, which is off by default. Users can switch the AI provider to GPT-4o or Groq in Settings. AI access is bundled with every plan — users do not need a separate Anthropic API key or account.
No. Nothing renews or charges you on its own. Starter is a one-time payment and never expires. Pro gives unlimited sessions for 3 months from purchase, and Premium for 6 months; when either ends, you can renew it for another term at the same price from the app, with the same licence key.
Yes. The product is priced in Indian Rupees and processes payments through Razorpay, which supports UPI, credit cards, debit cards, and net banking. The product is built primarily for the Indian market and English-language interviews. There is no geographic restriction on use.
Interview Assistant requires Windows 10 (64-bit) or Windows 11 (64-bit), 4 GB RAM minimum, and a persistent internet connection for license validation and AI inference. The installer is approximately 250 MB. The product is not currently available on macOS or Linux. macOS support is planned for the second half of 2027.
End-to-end latency from when the interviewer stops speaking to when the first answer token appears is typically 2.5 seconds. This consists of approximately 200 ms for Deepgram speech-to-text finalization, 1,500 ms for the silence-detection threshold that confirms the question is complete, and 800-1,300 ms for Claude to generate the first streamed token. Subsequent tokens stream continuously.
Interview Assistant supports technical coding interviews (LeetCode-style), system design rounds, behavioral interviews (STAR format), case interviews, product management and sales interviews, online assessments, panel interviews, and internship interviews. The product offers three named answer formats (concise, detailed, bullets) that map to different interview types.
Starter is ₹1,499 for 15 interviews total and never expires; Pro is ₹3,999 for unlimited sessions for 3 months, renewable. Both plans include the same core features: Claude AI access, real-time transcription, the invisible overlay, all three answer formats, and resume-aware prompts. Pro adds priority support and includes all future updates. The Premium plan at ₹7,777 is Pro with a 6-month term instead of 3.
For Indian job seekers, the best AI interview copilot is generally the one that accepts INR via Razorpay/UPI, prices in rupees, and offers a one-time payment option. CrackItX's Interview Assistant matches all three criteria: ₹1,499 one-time entry price, no subscription, and full Indian payment support. Final Round AI, LockedIn AI, and Cluely are subscription-only and bill in USD.
CrackItX's Interview Assistant is positioned as a cheaper alternative to Final Round AI for Indian users. Final Round AI Pro is approximately $58/month (₹4,800/month, ₹57,600/year). CrackItX Starter is ₹1,499 one-time, and CrackItX Premium is ₹7,777 for 6 months of unlimited use — less than two months of Final Round AI Pro. Both products are real-time AI overlays invisible to screen capture.
CrackItX's Interview Assistant uses Claude by Anthropic as its default AI model — Claude Sonnet 5 for answers, with Claude Haiku 4.5 for the optional quick one-line answer — and also offers GPT-4o and Groq as selectable providers. Several competitors also offer Claude as one of multiple model options, including Final Round AI, LockedIn AI, ParakeetAI, and Interview Sidekick. CrackItX includes Claude API access in the license price — no separate Anthropic account or API key is required.
Yes. The application captures system audio via Windows WASAPI loopback, which works regardless of which conferencing application produces the audio. Supported platforms include Zoom (desktop and web), Microsoft Teams (desktop and web), Google Meet (web), Cisco Webex, Slack Huddles, Discord, and HireVue. The overlay is invisible to the screen capture of all of these.
Setup takes approximately two minutes: (1) download the installer from crackitx.in/download and run it on Windows 10 or 11; (2) launch the app and paste the license key emailed after purchase; (3) fill in your profile — name, role, experience, resume, and job description — in Settings; (4) hit the play button to start a session when your interview begins. Ctrl+Shift+A triggers an answer manually if the silence-detection doesn't fire.
The ethical status depends on the policies of the specific employer and the type of interview. Use of AI assistance during interviews is not addressed in most standard candidate agreements and is not universally prohibited. Some employers explicitly forbid it for proctored assessments; others do not address it. Candidates should review any agreements signed and consider the conventions of the role they are interviewing for. CrackItX's Terms of Use restrict the product to practice and personal preparation; users are responsible for compliance with the policies of the assessing organization.
