Live Object Verification
Know it's real.
Before you commit.
Buying or selling, sharing a photo isn't proof. ProofLens verifies that an item was captured live, not reposted, edited, or faked.
Photo
The Problem
If anything can be faked, what counts as proof?
A listing photo tells you nothing about who took it, or when. Reposts and edits are hard to spot.
AI Generated
Real
How It Works
Beyond photos.
Beyond screenshots.
A short guided capture combines multiple real-world signals from the device to confirm live presence. It filters out replays, screen recordings, and static images. Only genuine live captures pass.

What people are saying
Based on feedback from trading communities.
“Authenticity is a huge issue in trading subs, so seeing liveness detection for it is great.”
“Especially useful for higher-value listings.”
“I like that it’s designed to be quick and simple for the user.”
“As someone who was inundated with fake verifications, I approve of this idea.”
“We need more tools like this. AI is just going to keep getting better at fooling us.”
“I think of ProofLens as a standard that anyone can ask for, in addition to photos via DM.”
Frequently asked questions
-
ProofLens is a verification app that helps prove an item is physically present with the seller at the time of capture. It works anywhere people buy and sell: Reddit, eBay, Facebook Marketplace, Depop, and other platforms. Unlike a regular photo or handwritten timestamp, a ProofLens proof is designed to stop reused images, screen replays, and AI-generated or edited content from passing as real.
-
You describe what you want verified and receive a secure capture code. Share that code with the seller, and they open it in the app to complete a short guided capture. Once finished, you can review the captured footage and the system's decision directly on your phone. The proof is either accepted or rejected.
-
Open the app, point your phone at the item, and follow the guided capture. It takes about 20 seconds. When it is complete, you get a shareable proof link that you can add to your listing or send to interested buyers. Anyone can open the proof in a browser without installing anything. Instead of having each buyer ask you for extra photos or timestamps, you create one proof and share it with anyone who asks.
-
During the guided capture, ProofLens analyzes real device signals, including the camera, motion, and other capture integrity checks, to verify that the item was recorded live and in person. It is designed to block common attempts such as screen recordings, photos of a screen, saved media, and AI-generated imagery. Each proof is evaluated by the system and marked as either accepted or rejected.
-
More photos are just files you have to trust, and modern editing tools make convincing fakes easy to create. A video can be pre-recorded, replayed from another screen, or edited. A video call is a reasonable option, but as a seller you would need to schedule one with every interested buyer instead of sharing proof once. And as a buyer, you can review a ProofLens proof, including the captured footage and the system's decision, on your own time, without coordinating a call. ProofLens provides a structured capture process that checks whether the item was actually captured live.
-
No. ProofLens works without requiring an account, email, or sign-up. There is no registration step to use it. We do not ask for identity information to create or view a proof. When sharing a specific proof, you can optionally include a reference code, like your Reddit username or listing ID, so the other party can confirm who the proof is from.
Get Started
Does it really work?
Curiosity welcome. Capture something real and watch it pass. Then try to fool it. For example, point the camera at a photo on a screen and see what happens.
