# hcalls

> hcalls is a real-time AI interview assistant and live copilot that streams structured, resume-matched talking points during live job interviews on Zoom, Google Meet, Microsoft Teams, and AI screening workflows when permitted.

hcalls listens to live interview audio and generates context-aware guidance in under 2 seconds. The product offers two delivery modes so you can keep coaching completely off the surface you share.

## Delivery Modes
- **Chrome Extension**: Captures Meet, Zoom, or Teams tab audio directly in your browser. [Guide](https://hcalls.com/chrome-extension)
- **Desktop App**: Native overlay. Install Windows from the [Microsoft Store](https://apps.microsoft.com/store/detail/XP9MNCPT2766RK). Win32 Display Affinity (`WDA_EXCLUDEFROMCAPTURE`) keeps the overlay out of supported screen-sharing tools.

- Needing structured STAR/CAR talking points tailored to your specific resume projects and metrics.
