Who is Gladia best for?

developersA strong fit for developers who need real-time or batch transcription plus multilingual audio enrichment through APIs.

enterpriseEnterprise teams get options for custom hosting, zero data retention, dedicated infrastructure, and support SLAs.
contact-center teamsContact-center builders can use live transcription and enriched transcript data for agent and call workflows.
Not for
  • Teams looking primarily for text-to-speech or full speech-to-speech voice-agent APIs should evaluate a broader voice platform.
  • Users who want a consumer transcription app rather than developer APIs, SDKs, and integration workflows may find Gladia too technical.
