For any service advertised as VR, look for explicit documentation naming your headset and explaining how it runs: a native application, a desktop connection or a browser experience. Check controller support, required hardware, supported operating systems and whether a separate subscription or application purchase is needed. A generic VR label is not a compatibility list.
For a screen-based avatar, check microphone permissions, voice-minute allowances and whether the feature works on your intended mobile or desktop browser. A subscription price cannot establish rendering quality, response delay or audio handling, and a voice flag does not tell you how long a call can last.
