A free interview copilot is only useful if it lasts long enough to test on a real conversation. On that measure our pick for 2027 is CoPilot Interview, with fifteen unbroken minutes a day and no card; we make it. Most free copilots look generous until you time them: two-minute tests, five-minute sessions, three sessions a month. This page sorts them by the thing that matters, the length of a single sitting, and shows how to stretch a short allowance across a real interview week. For the same comparison by total features, see the best free AI interview assistant for 2027.

Why session length beats total minutes
An interview answer runs for one to two minutes, and an interviewer's follow-ups depend on what came before. A five-minute cap can end during an answer and force you to start a new session, while the assistant loses the thread. Fifteen minutes will not cover a full loop, but it does cover the opening of a call or a whole recruiter screen, which is where a nervous candidate usually wants support. The traps around free plans, including trials that convert to paid, are in free trial traps to avoid.
Stretching a short allowance across an interview week
- Monday to Wednesday: one 15-minute mock interview a day, built from the job description. Read the transcript afterwards, which does not use any allowance.
- Thursday: a live test using a friend or a recorded question, to check audio and window placement.
- Friday, if the interview is that day: save the session for the first fifteen minutes of the call, if the employer's rules allow it. Start it when the interviewer starts talking, not while you wait in the lobby.
- If a long interview appears: a one-hour pack costs $9.99 and does not expire. How the free allowance works has the details.
- Afterwards: write down the questions you were asked while you remember them, then rehearse them tomorrow.
What a free copilot leaves out
- Longer sessions. Standard is 60 minutes for $24.99 a month and Pro is 70 minutes for $39.99 a month.
- Premium models. Fast free models answer most behavioral questions well, while paid tiers add GPT, Gemini and Claude.
- Dual AI Mode, which shows two models side by side on paid tiers.
- What it does not leave out: captions, structured answers, mock interviews and the résumé builder are on the free plan.
Where CoPilot Interview fits
CoPilot Interview is an AI interview assistant for Windows and macOS. The free plan gives 15 minutes a day of live help in sessions of up to 15 minutes, with AI mock interviews included, no card and no signup, and our full comparison for 2027 sets it against the paid alternatives. Free does not change the rules of the room: follow your employer's rules, and use the allowance for practice whenever a round is proctored.

Frequently asked questions
Which free AI interview copilot has the longest session?
As vendors stated in October 2026, CoPilot Interview, Sensei AI and Verve AI allow 15-minute sessions, but CoPilot Interview's allowance resets every day and Verve AI's allows three sessions a month.
Is 15 minutes enough for an interview?
It covers most recruiter screens and the opening of a longer call, not a full technical loop. A one-hour pack at $9.99 covers a single long interview.
Does the free plan include mock interviews?
On CoPilot Interview, yes. AI mock interviews read questions aloud and score spoken answers out of ten on the free plan.
Can I use a free copilot on the same day repeatedly?
On ours the daily allowance is 15 minutes in total, so one full session or several shorter ones, then it resets the next day.
What happens at the end of a free session?
The session stops. Plan for it by starting when the interviewer starts talking, and follow your employer's rules on whether to use it at all.
Practice this interview before the real one
The AI mock interview builds questions from your resume and the job description, reads them aloud and scores each spoken answer out of 10. Included on the free plan.
