AI Interview Assistant Pricing: Credits vs Minutes vs Subscriptions
Learn how credits, minutes, sessions, subscriptions, unlimited passes and taxes change the real cost of an AI interview assistant.

AI interview tools often use prices that look comparable but measure different things. One credit may mean a minute, half an hour, or one session. “$25/month” may require a full-year payment. The only fair comparison converts every offer into a tax-inclusive cost for your expected usage.
The five common models
Minute wallet
You buy a fixed number of minutes. Check the minimum billing block, extension behavior, and whether unused time expires. InterviewGPT currently uses wallet minutes for credit packs.
Session credits
A session token covers a fixed block, often 30 or 60 minutes. Short tests can waste value if a minimum fraction is deducted at start. Parakeet publicly explains credits through 30-minute blocks; verify its current rules before purchase.
Monthly subscription
You receive recurring access or an allowance. It fits a predictable active job-search month, but unused value may disappear and auto-renewal matters.
Annual-effective monthly price
The page displays a monthly equivalent but bills a year upfront. Always write “₹/$X per month, billed ₹/$Y annually.” Never compare it to a truly monthly offer without the commitment.
Time-limited unlimited pass
Usage is not deducted during a purchased validity window, but fair-use, block, or concurrency rules may still apply. InterviewGPT offers unlimited passes separately from its minute wallet.
A reusable calculator
Estimate:
I= number of interviewsD= expected duration per interviewP= practice/setup minutesB= minimum billed block or expected wasteT= tax and fees
Then:
needed minutes = (I × D) + P + B
effective cost per hour = (checkout price + T) ÷ (usable minutes ÷ 60)
Example: four 45-minute interviews plus 60 minutes of testing require 240 minutes before waste. A two-hour pack is insufficient even though it sounds close; a six-hour pack or short unlimited pass may be more predictable.
Hidden value and hidden cost
Non-expiring credits are valuable for interviews spread across months. A subscription may be better for a concentrated schedule. A broad suite can be worthwhile if you use mock interviews, reports, and resume tools—but poor value if you only need 90 live minutes.

- Whether practice consumes the same balance as a real session.
How to compare “free”
A free practice tool, a short live trial, a daily allowance, and a free browser are four different offers. InterviewGPT's Invisible Browser is the free manual feature; live AI sessions have a configured allowance. LockedIn, Parakeet, Chiku, Verve, Sensei, and other products publish their own credit/session trials. Convert each to the specific task you can test rather than adding unlike minutes together.
Choosing InterviewGPT access
Start with the current free allowance to test audio and answer fit. Use the Invisible Browser if a manual embedded browser solves the task. Choose non-expiring credit minutes for occasional interviews; compare an unlimited pass for a dense interview period. Recalculate from the live pricing page, because the values are configurable.
