Interview copilots and AI interview platforms charge mid-size companies in four ways: per interviewer seat, per interview conducted, per hire, or a platform fee with usage tiers. At 50 to 500 hires a year the bill is driven less by the headline price than by how many people interview, how many rounds each candidate has, and whether you pay for candidates who never advance. This page compares the four models without quoting other vendors' prices, which change often, and gives you the questions that make a quote comparable.
The four pricing models
| Model | You pay for | Favours you when | Watch out for |
|---|---|---|---|
| Per interviewer seat | Each person who runs interviews | Few interviewers, many interviews | Occasional panelists who need a seat for one loop a quarter |
| Per interview | Each scored conversation | Many interviewers, few interviews | Multi-round loops multiply the count |
| Per hire | Each accepted offer | Low offer rates | Rising unit price as you scale |
| Platform fee plus tiers | A base fee and usage bands | Predictable budgeting | Paying for a band you do not fill |
The question that decides between seat and per-interview pricing is simple: divide your annual interviews by your active interviewers. Above roughly thirty interviews per interviewer a year, seats are usually cheaper.
What drives the bill at 50 to 500 hires
- Interviews per hire. A four-round loop with a 20% offer rate means twenty scored interviews per hire. Per-interview pricing punishes long loops.
- Panel size. Two panelists on each round doubles seats or interviews depending on the model.
- Occasional interviewers. Engineers who interview once a month need access without a full seat; ask how the vendor handles them.
- Integration and SSO. Often gated behind a higher tier; decide whether you need them in year one.
- Candidate volume you never interview. AI-interviewer platforms that screen every applicant charge for that volume; copilots for human-run interviews do not.
Questions that make quotes comparable
- What exactly is a unit: a seat, a scored interview, a hire, or a month?
- How are occasional interviewers priced?
- Which features sit behind a higher tier: SSO, templates per role, a central evaluation view, data export?
- What is the data retention default, and can we shorten it?
- Is there a free tier or pilot we can run on one requisition before signing?
- What happens to our reports if we leave?
Our explainer on employer versus candidate AI interview tools helps separate quotes for human-run interview copilots from quotes for AI-conducted interviewing platforms, which are different products with different cost curves.
A worked example
A 300-person company hires 80 people a year through a three-round loop with a 25% offer rate: 960 scored interviews across about 40 interviewers, or 24 interviews per interviewer. Per-interview pricing bills 960 units; seat pricing bills 40 seats, a third of whom interview fewer than ten times. Here a hybrid is often best: seats for the recruiting team and the busiest hiring managers, and a per-interview or free option for everyone else. The cheapest line in the budget is a copilot whose base version is free and whose team plan is priced by volume, which is how CoPilot Interview is set up; our cost guide covers the candidate-side plans.
Where CoPilot Interview fits
CoPilot Interview's Interviewer Mode is included in the free desktop app that candidates use as an AI interview assistant, so individual interviewers can start at no cost. For mid-size teams, team and enterprise plans add volume licensing, centralized billing, SSO/SAML, custom question templates per role and a centralized evaluation dashboard, priced for groups rather than individual sign-ups. Compare any quote on the questions above, and follow your employer's rules on procurement and candidate notice.
Disclosure: CoPilot Interview is our product, so weigh what we say about it accordingly.
Frequently asked questions
How are AI interview copilots priced for mid-size businesses?
Per interviewer seat, per scored interview, per hire, or a platform fee with usage tiers. The right model depends on interviews per interviewer and the length of your loop.
Is per-seat or per-interview pricing cheaper?
Divide annual interviews by active interviewers. Above about thirty interviews per interviewer a year, seats are usually cheaper; below that, per-interview pricing or a free base tier often wins.
Does CoPilot Interview charge per interview?
No. Interviewer Mode is free in the desktop app for individual interviewers, and team plans use volume licensing with centralized billing. Contact details are on the enterprise page.
What features are usually behind higher tiers?
SSO, templates per role, a central evaluation view, data export and integrations. Decide whether you need them in year one before comparing prices.
What should a pilot look like before signing?
One requisition, three to five candidates, the tool disclosed to each, and a debrief judged on whether it was shorter and more evidence-based.
