One tool. Four modalities.
Our DETECT-3B Omni model, free for everyone.
This free site runs the same detection models we deploy in production for fraud, voice verification, and content moderation at scale. Upgrade to the API when you're ready.
More than a detector.
A full trust layer for AI media.
HIBP for breaches. VirusTotal for malware. detectdeepfakes.com is the trust utility for synthetic media — free tools for the world, powered by the same stack Resemble AI deploys to banks, telcos, and newsrooms.
Paste any URL — we extract the text and images, run every asset through our detectors, and return one unified risk report.
Check any audio, image, or video for Resemble's multimodal watermark. C2PA and SynthID layering in development.
Upload a voicemail. We flag AI-generated voice and map it against 20 known scam scripts — the engine banks and telcos use in production.
Every major deepfake incident on record, documented with cited sources. Free to cite for journalists and researchers.
Public, reproducible benchmark across 14 commercial detectors. Pre-registered methodology. Q4 2026 inaugural publication.
Drop our detector into your own site or newsroom. One script tag. Free for non-commercial use.
Built for people who need to be right.
Newsrooms
Verify a viral voice note before it hits publication. Paste the file URL, read the reasoning, cite the detector in your piece. No login.
Banks & call centers
Catch synthetic callers attempting account takeover. The free tool is the consumer surface of the same DETECT-3B model running in production at telcos and financial institutions.
Trust & safety
Screen user-uploaded content at scale via the API. Multimodal: one call, one verdict across audio, image, and video.
But we did.
Synthetic media has outpaced the tools most teams have to detect it. The volume and quality of AI-generated voices, faces, and video jumped an order of magnitude in the last 18 months — and it's still accelerating.
We build the whole generative AI security stack.
From day one we built voice AI with provenance and detection in mind. We're the only platform that generates, verifies, and detects across voice, image, and video — and this free detector is one surface of that stack.
Get complete generative AI security.
When you're ready to run detection in your own product, the Resemble AI API ships the same models with sub-300ms latency, PerTh watermarking, and on-prem options. 50 free scans/month, no credit card. SOC 2 · GDPR · HIPAA.
