Our pick for the best free AI assistant alongside a Microsoft Teams interview in 2027 is CoPilot Interview, which we make: it runs in its own window, does not join the meeting, and gives 15 minutes a day with no card. Teams interviews have some quirks: you will usually join as a guest, you may wait in a lobby, and the desktop and browser versions behave differently. Check these the day before. More is in our Teams page and the Teams assistant guide.

Guest-join checks for the day before
- Open the invitation link and see whether it offers the browser. Joining Teams as a guest covers each path.
- Sign out of any work account, so you do not join the interview under your employer's name.
- Check the name shown when you join, and use your full name.
- Allow the microphone and camera in the browser.
- Pick one output device, and test it with the assistant running.
- Expect a lobby, and keep the assistant's window ready rather than starting your free session early.
- Keep the interviewer's email to hand in case the link fails.
Microsoft Copilot in the meeting
The employer's Teams setup may include Microsoft's own Copilot, recording or transcription. Those belong to the organizer and may be used by them. You may see a notice. That does not change what you are allowed to do; if you are told that outside tools are not allowed, follow that. If you are asked whether you are using anything, answer honestly.
On the day
- Join ten minutes early, since a guest may wait in a lobby.
- Keep the interviewer's email to hand in case the link fails.
- If the desktop app misbehaves, switch to the browser rather than reinstalling.
- If you lose the call, rejoin first and explain afterwards, as a dropped call is common and rarely held against you.
Where CoPilot Interview fits
CoPilot Interview is an AI interview assistant that runs in its own window beside Teams on Windows and macOS and never joins the meeting. The free plan gives 15 minutes a day of live help in sessions of up to 15 minutes, with AI mock interviews included. Whatever tool you choose, follow your employer's rules, and use it for practice in any round that forbids outside help.
Disclosure: CoPilot Interview is our product, so weigh what we say about it accordingly.
Frequently asked questions
What is the best free AI assistant for Teams interviews?
Our pick is CoPilot Interview, which we make, with 15 minutes a day and no card. It runs beside Teams and does not join the meeting.
Should I use the Teams app or the browser?
If you do not have an account, the browser is often easiest. Test whichever you choose the day before.
Do I need a Microsoft account?
Not usually for a guest. Follow the link and choose to continue in the browser if it offers that.
Why does it not hear Teams?
Check that Teams or your browser plays through the same device your assistant is reading.
When should I start my free session?
When the interviewer starts talking, not while you wait in the lobby, since sessions are limited to 15 minutes.
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.
