●Viral content
Check it before you share it.
Viral clips, screenshots and photos that look a little too perfect. Find out if they are real in seconds.
●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 → AI-generated<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 spreads fastest.
Flagged at the point of submission, before it reaches a reviewer.
01
Fake news footage
Generated events and disasters.
02
Celebrity fakes
Face swaps and cloned voices of public figures.
03
Too-perfect photos
Images that look polished because they were generated.
04
Fake screenshots
Edited chats and posts.
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 Real, AI-generated or Skip, with the likelihood, signals and audit ID behind it.
One answer●In your feed
One click.
Scan any image with the Chrome extension.
Drop the file into Witness to check it.
See the result and heatmap first.
●How it works
Three steps. One result.
Find it
Spot a clip or image that feels off.
Check it
Upload it or scan in Chrome.
Share or skip
Use the result and reasons to decide.
●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://…/viral_clip_frame.jpg"}' → 200 OK · 412ms result: ai_generated · 0.94
●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.
