Parakeet AI is reported to sell access as packs of credit hours drawn down by how long a session stays open, so the meter runs on wall-clock time: the lobby, your own answers and the silent half of a coding round all cost you. OfferPilot AI meters listening time only, so the clock advances just while interviewer audio is arriving. Across the same fourteen interviews that is 13.4 billable hours against 1.9. Architecture is the second decision, because a browser tab and a native overlay behave very differently in a live coding round.
What a credit-hour actually buys
Hourly credit is easy to understand, which is why people like it. It is also unforgiving about a fact nobody plans for: an interview occupies far more session time than it contains speech. Two burn figures first.
- A booked 45-minute screen fills about 50 minutes of open session. You join early, they join late, it runs over while they answer your last question.
- A booked 60-minute technical fills about 65 minutes, same reasons plus the five where somebody gets an editor working.
Now the speech side. In a behavioural screen the interviewer speaks for around 11 of those 50 minutes: an intro, six questions, context between them, their own pitch at the end. In a technical round it collapses to about 5, because they read the problem out, clarify constraints, then go quiet while you work.
Three job-search loads, costed out
Two rounds is one company. Six is an onsite loop plus a couple of screens. Fourteen is a real search, four companies taken to the end, split evenly between conversational and technical.
| Load | Wall-clock hours a credit meter bills | Hours a listening clock bills | Ratio |
|---|---|---|---|
| 2 rounds (1 screen, 1 technical) | 1.92 h | 0.27 h (16 min) | 7.2× |
| 6 rounds (3 screens, 3 technical) | 5.75 h | 0.80 h (48 min) | 7.2× |
| 14 rounds (7 screens, 7 technical) | 13.42 h | 1.87 h (112 min) | 7.2× |
The arithmetic is open, so check it: 50 and 65 minutes for the wall-clock column, 11 and 5 for the listening one. If your interviewers talk more than mine, raise the 11 and the ratio narrows. It never inverts, because your own talking time is free on one clock and billed on the other.
Turning that into money
Pack prices move, so use the formula rather than a figure that will be stale by the time you read it. Divide a pack price by its hours for a rate per credit-hour, call it C. A mixed round averages 0.96 credit-hours under the burn figures above, so cost per interview is roughly 0.96 × C, and that number is flat: two rounds or twenty, you pay the same each.
A daily allowance does the opposite, falling the more you interview. At $39 a month for three hours of listening a day: $19.50 per interview across two rounds in a month, $6.50 across six, $2.79 across fourteen. The crossover sits at 39 / (0.96 × C) rounds a month, about 40.6 / C.
| If a pack works out at | Cost per interview on the pack | $39 monthly plan is cheaper from |
|---|---|---|
| $5 per credit-hour | $4.80 | 9 rounds a month |
| $10 per credit-hour | $9.60 | 5 rounds a month |
| $15 per credit-hour | $14.40 | 3 rounds a month |
One number matters more than all of that. The whole fourteen-round load bills 1.87 hours, which fits inside a single day of the three-hour allowance. So the real question is not what a month costs, it is whether your heaviest day fits. Tiers are on the pricing page.
Where the wall-clock meter quietly leaks
The lobby
You open the tool at 13:57 for a 14:00 call. They join at 14:06 after a prior meeting overran. Nine minutes of credit on an empty waiting room, and a listening clock counts none of it.
Your own thirty minutes
In a good behavioural round you do most of the talking, so on a wall-clock meter your best answers are the most expensive part of the day. On a listening clock they cost nothing, and holding M pauses the mic.
The silent coding stretch
They read a problem in ninety seconds, then watch you type for thirty-five minutes. A credit meter charges the full round; a listening clock charges the ninety seconds. That is why leaving it running through a long pairing session stops being a decision you weigh up.
Browser tab or native overlay, in a live coding round
This is the row people skip and then regret. Parakeet AI is reported to run as a web app, so verify that before buying: architecture decides what a tool can hear and where you look while it answers.
| Browser-based copilot (general behaviour) | OfferPilot | |
|---|---|---|
| What it can hear | Generally needs the call in a browser tab with tab audio shared, so a desktop Zoom or Teams client may be inaudible | System playback loopback, so it hears whatever the machine plays, desktop clients included, and works with headphones |
| Where transcription happens | Sent onward for processing, normal for a web app. Ask where it lands. | On-device with Whisper |
| Where you read the answer | A second tab, window, monitor or phone | An overlay over whatever is already on screen |
| Focus and tab events | Reading it means moving focus. HackerRank and Codility log tab and window changes on many configurations. | No focus change needed, though the platform's rules still govern whether assistance is permitted |
| If you share your whole screen | The tab is part of your screen and captured with it | Excluded from capture at OS level, on every plan including free |
| A problem spanning several scrolls | Copy and paste, or manual screenshots into an upload box | Ctrl+Alt+S, drag a box, about 3 seconds to scroll, drag again, repeat, Enter sends every shot together |
| Platform | Anything with a browser, macOS included | Windows 10 and 11 only. No macOS, Linux, mobile or extension. |
Multi-shot capture matters more than it sounds. A problem with a long constraint block and three worked examples rarely fits one screen, and a tool that takes one image gets half the question and solves the wrong one. Code Copilot stitches the shots and returns intuition, a dry run and Big-O.
When a credit pack is the better purchase
- You interview rarely. One round a quarter against a monthly subscription is a bad trade, and hours sitting in an account do not need cancelling. Check the expiry terms, because packs of this sort often expire.
- You need a predictable number. Hours bought is hours owned. A listening clock cannot promise a per-interview figure in advance, because billed minutes depend on how talkative a stranger turns out to be. A panel of four who each spend six minutes on background burns far more than one terse staff engineer.
- You are on a Mac. OfferPilot AI has no macOS build and no web app standing in for one, since the capture exclusion is built against Windows compositing behaviour. That ends the comparison rather than footnoting it.
Two further limits. A daily allowance is daily, so six hours a day is not a pool you can bank for one brutal Thursday, and the free tier is five minutes a day, a latency test rather than a free interview. The same billing-unit question is worked through against a per-session competitor on the LockedIn AI comparison.
What the hidden overlay does and does not cover
Capture exclusion means the overlay is composited out of screen sharing and recording at operating system level. Zoom, Teams, Meet, OBS and a plain screenshot all show your desktop without it, while it stays visible on your own monitor. That is the whole claim. It does not defeat a webcam, a lockdown browser on a proctored assessment, an in-person invigilator, eye tracking, or a phone filming you from the side of the room. Where a process forbids outside help, no overlay makes it permitted, and those limits apply to every product here, browser-based ones included.
Run your own numbers
Time one mock round and count how long the other person actually speaks. That measurement settles which pricing model suits you better than any table, this one included. Then download for Windows and check the maths on a real round.
