PRSN.
Our newest product: a human-only social network built to keep out bots and AI slop. Live now on the App Store.
01 · The idea
Proof of person.
PRSN (pronounced "person") is a human-only social network built to keep out bots and AI slop. Instead of CAPTCHAs, every member proves they're human with a quick physical challenge: sway your phone in time with a haptic cue. Powered by a sensor-driven verification system on iOS, engineered to resist automation, emulators, and instrumentation.
02 · How it verifies
No CAPTCHAs. A handshake.
-
Physical Human Verification
No CAPTCHAs. Members sway or tap their phone in time with a haptic cue to prove they're real.
-
Sensor-Driven Trust
Device motion and haptic sensors confirm a real person is holding a real phone.
-
Automation-Resistant
Engineered to resist automation, emulators, and instrumentation.
-
Tested in the Open
A public bounty program rewards anyone who can bypass the verification system. The app is stress-tested in the wild, not behind closed doors.
03 · The network
Humans, in their own words.
