●Trust & safety · Platforms
Screen uploads for AI-generated media at scale.
Flag generated profile photos, synthetic listings and manipulated uploads at the point of upload, and route them to review with the signals attached.
●Platform
Detect it. Explain it. Act on it.
Every scan returns the same three things: a result, the signals that produced it, and a decision you can route on.
01
Detect
Every file is scanned by independent models for images, video and faces, in the web tool, the extension or by API.
3 / 4 signals corroborateCalibrated likelihood
02
Explain
See which signals fired and how strongly. No single model decides; every result comes with its reasons.
Rule: likelihood ≥ 0.85 → Queue<3s
03
Route
Branch your workflow on the result. Clean items pass, flags go to review with a full audit trail.
●What we catch
What gets through today.
Flagged at the point of submission, before it reaches a reviewer.
01
Generated profile photos
Fake faces behind bot networks, scams and fake reviews.
02
Synthetic listings
Generated product, rental and property photos that don’t exist.
03
Manipulated uploads
Edited or face-swapped images used for harassment or impersonation.
04
Reused images
The same image across many accounts, caught by perceptual hashing.
The pipeline
A detector for each kind of media.
Image, video and voice each have their own detector. Their findings come back as one clear answer you can act on.
Image
Diffusion, GAN and face-swap images from Midjourney, DALL·E, Stable Diffusion, Flux and Firefly.
LiveVideo
Face swaps across 32 frames and fully generated video from Runway, Kling, Veo and Pika.
LiveVoice
Cloned and synthesised speech in calls, notes and recordings.
LiveWhat you get
Each file is marked Allow, Queue or Review, with the likelihood, signals and audit ID behind it.
One answer●Where it runs
One check, every upload surface.
Score avatars and verification photos at account creation.
Screen product and property photos before they go live.
Give moderators the signals behind every flag.
●How it works
Three steps. One result.
Send media
POST each upload to the API, synchronously or in batch.
Branch on the result
Allow, queue or block on likelihood or individual signals.
Review with context
Moderators see the heatmap, signals and audit ID.
●Integration
Three ways in.
Start with the web app.
Scan in the web app or Chrome extension today. The REST API and MCP server for your AI agents are coming soon. Same detectors, same result, same audit trail.
Web app
AvailableUpload in the web app. Images, video and voice, up to 50 MB. Full results in seconds.
Chrome extension
AvailableScan any image or video from inside the tools your team already uses. No download, no upload.
API
SoonSingle scans, batch jobs and webhooks. Structured JSON with result, likelihood, signals and audit ID.
curl -X POST https://witness.vision/api/v1/detect \ -H "Authorization: Bearer $WITNESS_KEY" \ -H "Content-Type: application/json" \ -d '{"media_url": "https://…/profile_upload_99812.jpg"}' → 200 OK · 412ms result: ai_generated · 0.92
●Why Witness
Built to be checked.
We say what the system does, what it returns and where its limits are.
Detection built per signal
Specialized models per signal, so you get more coverage and fewer false positives than one classifier.
Reasons, not just a score
Every result shows the signals behind it and where in the file they fired.
Analysed, then gone
Media is never stored, shared or used for training.
Provenance, when it exists
Reads Content Credentials from capture device to current file.

●Explore
One engine. Every surface.
The same detection, result and audit trail across every team that handles media.
Detection
AI image detector
Find out if an image was made by AI.
Explore →Detection
Face swap detection
Find out if the face in a photo or video has been replaced, reenacted or lip-synced.
Explore →Detection
C2PA checker
Read the Content Credentials inside an image or video: who signed it, what captured it, and every edit since.
Explore →Detection
AI video detector
Find out if a video was generated by AI or contains a face swap.
Explore →Product
Chrome extension
Scan media on any site, social feeds, news, claims portals, case files, and get a result in the side panel..
Explore →Can it run on every upload?
Yes. The API handles synchronous checks and batch jobs. It is coming soon, talk to us about volume.
Do you store our users’ media?
No. Media is analysed and discarded.
Can we set our own thresholds?
Yes. Every response includes the likelihood and per-signal scores so you can write your own rules.
