We're not a courtroom expert witness, and we can occasionally lag a brand-new generator by a few days — we publish accuracy benchmarks rather than hide that. Read the full picture ↓

Verdict scale

Three signals. One verdict.

Face-artifact analysis

Catches the visual tells fake video leaves behind — unnatural blinks are one example. Detection updates as the generators change.

Voice-splice detection

Flags the seams where cloned or spliced voice audio doesn’t hold together — a missing breath pattern is one tell. Cross-checked against your voiceprint if you’ve enrolled.

Metadata and provenance

Reads the file’s own history for signs it was re-encoded to hide edits. Where the file carries C2PA provenance, we report it — we never fabricate a signal.

Four-band verdict

Real / Probably real / Probably fake / Fake. Four plain bands, each mapping to an action — because a lone percentage gets misread.

Verdict explanation

Each verdict carries a short, plain-language explanation of which signals contributed — useful when you have to defend the decision to a colleague.

Source attestation under Executive

Executive customers can run verdicts against their own enrolled voiceprint and verified-profile baseline — a personalised ‘is this really me?’ attestation.

The wire-transfer scenario, set in 2026

Deepfake-CEO wire fraud is real — the intervention point is 90 seconds before the transfer, when someone runs the clip through a check.

A clip arrives in your finance team’s inbox. It looks like a video call recording with the CEO. The CEO is asking for a $4.2 million wire to close an acquisition before the EU window shuts. Voice matches. Face matches. The urgency matches the CEO’s actual schedule. Send the wire today, the CEO says, we’ll do the paperwork tomorrow.

This is the playbook that settled $25 million out of an Arup engineering office in Hong Kong in 2024. The synthetic-media tooling has gotten cheaper and faster every quarter since. The intervention point isn’t the wire-approval workflow. It’s ninety seconds before that. Someone on the finance team drops the file into a deepfake check and waits for a verdict.

That is what this product is.

What we actually look at

Three signals — face artifacts, voice splices, and metadata — feed one four-band verdict, each band tied to a clear action.

Three pipelines run in parallel on every upload: face-artifact analysis, voice-splice detection, and metadata-and-provenance checks. Each looks for the tells its layer leaves behind. See the trust ledger for the forensic detail and our published benchmarks.

The three feed a verdict in one of four bands, each tied to an action. Real means trust the source. Probably real means trust but verify out of band. Probably fake means don’t act on this. Fake means escalate.

What we are honest about

We are not a courtroom expert witness. We will sometimes be late against a generator that ships the same week we run the verdict. The model arms race is real. So we publish accuracy benchmarks against current commodity generators in the trust ledger rather than hand-wave at it. The verdict is a 90-second editorial sanity check. It catches the large majority of current deepfake content, with very low false-positive rates against the probably-fake and fake bands. For litigation, we refer you to qualified forensic vendors with the right chain-of-custody discipline.

Personalisation under Executive

On Executive, verdicts run against your enrolled voiceprint — answering not just “is this fake?” but “is this really you?”

A generic deepfake verdict says “this voice was probably spliced.” When the speaker is an enrolled customer, an Executive verdict adds “and it does not match your enrolled voiceprint.” That second answer is the one that matters. The question is whether your CEO actually made the call. See Executive Identity Defense and Voiceprint Protection for the enrolment and consent detail.

Who uses it

CFOs and finance teams handling wire-transfer requests

Deepfake-CEO wire fraud is real — the 2024 Arup case lost ~US$25M to a deepfaked video call. Run the video first.

Journalists and fact-checkers

A verdict on a viral clip before you embed it. Not a courtroom finding — a same-day sanity check that catches what the eye misses.

Family members verifying voice-clone scam calls

A relative gets a panicked voice call asking for money. Record the next call, upload it, get a voice-splice verdict against Voiceprint Protection.

HR and security teams responding to impersonation incidents

A clip surfaces purporting to be a senior executive. Run the verdict before comms responds. Executive runs against an enrolled baseline; Pro runs generic signals.

Frequently asked questions

What's your false-positive and false-negative rate? #
It depends on the underlying generator. Against current commodity face-swap models, our published benchmarks show a low single-digit false-positive rate at the probably-fake / fake threshold. Against bleeding-edge generators released the same week, we can be late — that’s why the verdict has four bands and an explanation. It’s a 90-second second opinion, not a courtroom expert.
Why a four-band verdict instead of a confidence percentage? #
Because non-specialists misread a number like 73% as either definitely real or definitely fake, depending on which way they’re leaning. Four bands with an explanation map cleanly to a decision: real, probably real, probably fake, fake. Confidence percentages are still there in the verdict detail for users who want them.
Do you store my uploaded file? #
No. The source file is deleted after analysis completes. The verdict (the four-band result, the explanation, and contributing signal summary) is retained in your dashboard for 90 days for your records. If you need longer retention, you can download the verdict PDF or opt into extended file retention from your dashboard settings.
Can I use this in court? #
Not directly. A KnytX verdict is a same-day editorial sanity check; courtroom-grade deepfake forensics require an expert witness, chain-of-custody documentation, and specialist tooling. We will refer you to qualified forensic vendors if your situation is moving toward litigation.
What's different on Executive? #
Two things: unlimited verdicts versus ten a month on Pro, and the ability to run a verdict against your own enrolled voiceprint and verified-profile baseline. The Executive verdict is personalised — ‘is this really me?’ — not generic. See Executive Identity Defense.
What file formats and platforms are supported? #
MP4, MOV, MKV, AVI, WAV, MP3, M4A, FLAC, and the common variants. URLs from YouTube, Vimeo, X (Twitter), Instagram, TikTok, LinkedIn, Telegram, and WhatsApp media links are accepted — paste the link, we fetch and analyse. Live calls are out of scope; record the call and upload the recording.

When the CEO's video asks for a transfer, run the clip first.

Ten checks a month on Pro. Unlimited on Executive. Drop the file, get the verdict, decide.
