The integrations directory names Twilio, GoHighLevel, HubSpot, Salesforce, Zapier, Make, n8n and Google Workspace. The homepage lists HIPAA, SOC 2 Type II, GDPR and ISO 27001 compliance, along with SSO, personal information redaction and module-level role permissions.

SoundHound is a mobile app for identifying music nearby and finding songs with voice control. Users can also sing or hum a tune to identify it. Saying “Hey SoundHound…” can navigate the app, start music discovery, and control playback hands-free. LiveLyrics displays moving lyrics in real time. The app connects Apple Music or Spotify accounts and includes a built-in YouTube player. Discoveries can sync across devices and be shared through Facebook, Twitter, messaging services, or email. Its Apple Watch app identifies music and displays LiveLyrics; a cellular-enabled watch can be used without an iPhone connection. SoundHound is available on Android and iOS, and keeps an identification history, but does not identify music offline. The free app includes advertising. SoundHound∞ is an ad-free upgrade listed at $6.99 as a one-time purchase, with no monthly fees. Personalized playlists through Apple Music or Spotify require a SoundHound account and a music subscription; voice playback of Spotify playlists also requires a Spotify account and registration. The company identifies itself as SoundHound AI Inc., headquartered in Santa Clara, California.
