Our pick for the best free AI interview assistant on Windows going into 2027 is CoPilot Interview, which we make: it runs on Windows 10 and 11, comes from the Microsoft Store or a direct download, and gives 15 minutes a day with no card. The setting that decides whether any tool works on Windows is the audio output, so that is what most of this page covers. Compare it with paid Windows options in the Windows comparison, and with everything else in our full comparison for 2027.

The audio setting that decides everything
A desktop assistant hears the sound Windows is playing. If your meeting app is sending audio to one device and the assistant is reading another, the captions stay empty. Windows sound settings for interview apps covers this in full. In short: pick one output device, such as your headset, in Windows and in the meeting app. Avoid enhancements and virtual devices you do not need. Bluetooth headsets can switch to a low-quality mode when the microphone is in use, so a wired headset is more reliable if you have one.
A ten-minute check on your machine
- Install from the Microsoft Store or the official download page.
- Open your meeting app and join a test call.
- Play a video with speech through the same headset and check that captions appear.
- Say a sentence and check that your microphone is picked up separately.
- Run one mock interview so you know how the window behaves.
- Check that Windows updates will not restart your machine during the interview, using active hours.
- Close anything that uses a lot of memory.
If you are on Windows 10
Windows 10 is out of mainstream support, but it still runs our app, and the Windows 10 guide covers what that means. Some tools no longer support it, so check before you pay anyone. On a work laptop, policies may block installation or audio access. If so, use a personal computer, or practice in the browser at /try. Do not try to work around your employer's restrictions.
