Resemble AI is Built for the Generative AI Era

Gen AI Deepfake Detection

Our DETECT-3B Omni model identifies synthetic content from 1,320+ generative AI models including ElevenLabs, OpenAI, Pika, and Runway. 95% accuracy, 6x faster than realtime.

3-Second Enrollment

Using few-shot learning, users can enroll with just 3 seconds of speech. No scripted phrases, no repetition required. Drastically reduces friction and abandonment.

Language Agnostic

Our 1 billion parameter Resemblyzer model is trained on massive multilingual datasets. A speaker’s identity vector remains consistent across Japanese, English, Spanish, and 40+ languages.

Explainable AI with Intelligence

Resemble Intelligence provides natural language forensic reports explaining why content was flagged. Essential for regulatory audits and dispute resolution in financial services.

Privacy by Design

Audio is processed in RAM/VRAM only—never stored to disk. Streaming protocol enables continuous analysis without creating persistent copies. Full data sovereignty.

On-Premise & Air-Gapped

Deploy behind your firewall with complete data sovereignty. Docker/Kubernetes native, no external dependencies. Meets the strictest compliance requirements globally.
