The first Human Presence
Protocol for the Internet.
Old CAPTCHAs ask “is this browser probably human?”, a question AI now answers for free. Manav asks a harder one: is a real human present right now? A browser session, a trusted device, and one real-time tap. No puzzles, no account, nothing biometric stored.
Show the request
A site shows a QR for the action that needs a human.
Scan & tap
The person scans with their phone and taps once to confirm presence.
Verified in ~1s
The browser instantly confirms a present, continuous human.
Three ways to prove a human
The same signup form, three drop-in human checks. Pick the one that fits your product, each one unlocks the same “Create account” flow.
Scan with phone
Tick “I’m human,” scan the QR with a phone, and tap once. Real-time presence on a second device, hardest for bot farms.
Try it Face checkQuick face check
A fast on-device face scan proves a live, present person. Your photo is never stored, only a private match.
Try it Press & holdPress & hold
Hold the control for a moment. A sustained, trusted human touch, zero friction, nothing stored on the device.
Try it Mouse movementJust move your mouse
No click, no hold. Natural cursor motion, curves, changing speed, tiny corrections, verifies a human as you move over the box.
Try it Swipe gestureSwipe across
Follow a prompted direction, sweep the cursor left→right or right→left across the box. A deliberate, directed human gesture.
Try it Tap in orderTap the numbers
Shuffled tiles, tap them 1 → 2 → 3 → 4. The order changes every load, so a recorded replay won’t pass.
Try it Slide to fitMatch the colour
A box that’s green or red at random, as you drag it near a border, the borders change colour. Drop it on the one that matches. Positions change every load.
Try it Hidden spotFind the hidden spot
The answer is never in the page. The server hides a spot on the track and only says warmer or colder as you slide, then verifies your drop and your search server-side.
Try it Press & rotatePress, hold & rotate
Hold the dial and turn it one full circle. The server re-measures your motion, a hand’s wobble passes, a script’s perfect circle doesn’t.
Try it Follow the dotFollow the dot
Keep your cursor on a moving target for about a second. Smooth human pursuit fills the bar; a jumpy cursor can’t.
Try it Reaction tapTap when green
Wait for the box to turn green, then tap. Too early, or inhumanly fast, doesn’t count.
