Draw a line. Count who crosses
it — in versus out.
Aim a camera at a doorway, drag the line across it, and on-device AI counts each person crossing as an entry or an exit — with a live occupancy total. The video is analyzed on your device and never uploaded.
Free demo: 5 sessions a day, 5 minutes each. Pro unlocks continuous counting (no time limits, run as long as your browser is open) and saves every session to a foot-traffic dashboard — entries, exits, and occupancy over time, with CSV export.
Go ProA line at the door, counted both ways.
Draw the tripwire, pick your direction, and let it tally entries, exits, and live occupancy — free in short sessions, saved for Pro.
01 / Place it
Draw the line
Drag a tripwire across the doorway — vertical or horizontal — and fine-tune either endpoint.
02 / Direction
In vs out
Each person is counted as an entry or an exit by which way they cross. Tap Swap if your inside and outside are reversed.
03 / Live
Occupancy in real time
Inside = entries minus exits, updated as people cross — so you always know how many are in the room.
04 / Honest
One at a time counts cleanest
A normal single-file doorway is the sweet spot; crowds and overlap reduce accuracy, and Undo fixes a miscount.
05 / Private
Video stays on your device
Detection runs in your browser and the video is never uploaded or recorded — only the counts save, and only on Pro.
06 / Pro
Foot-traffic dashboard
Pro saves each session and charts your entries and exits over time, with a full history and CSV export.Before you point the camera.
Q.01 How does the entry/exit counter work?
Your camera feed is analyzed in your browser with on-device AI that detects people and follows each one frame to frame. You draw a line across a doorway; when a tracked person crosses it, they are counted as an entry or an exit depending on which way they crossed. Occupancy is simply entries minus exits. The video is never uploaded.
Q.02 What camera do I use? Can I connect a security/IP camera?
This version uses the camera on the device running it — a phone, tablet, or a laptop/desktop webcam. Prop the phone at the doorway, or point a webcam-equipped laptop at it. It does not connect to a standalone Wi-Fi/IP security camera: browsers cannot read those camera streams directly, so those need extra server software we do not run here.
Q.03 Is anything uploaded — the video, or the counts?
The video is never uploaded. All detection happens in your browser; the video is never sent to our servers, recorded, or stored — close the tab and it is gone. The counts are different: on the free plan nothing leaves your device at all. With Pro, when a session ends we save just the numbers — entries, exits, peak occupancy, and duration, never the video or any image — to your account, so you can track foot traffic over time on your dashboard.
Q.04 How accurate is it?
Best case is a normal doorway with people crossing roughly one at a time — that counts reliably. Accuracy drops when several people cross abreast, when they overlap or block each other, or in a wide, busy entrance, because the AI can lose track of who is who. Treat busy-scene totals as an estimate, and use the Undo button to fix a miscount.
Q.05 Does it keep counting if I switch apps or the screen turns off?
No — and nothing can. A web page cannot watch a doorway in the background: browsers pause the camera when the tab is hidden or the screen sleeps. The counter keeps your screen awake during a session, but it only counts while this page is open and in front.
Q.06 What do I get with Pro?
The free demo gives you a few short sessions a day, five minutes each. Pro unlocks continuous counting — run as long as your browser is open, no time limits — and saves each finished session to a foot-traffic dashboard: your entries and exits charted over the last two weeks, a full session history, and CSV export. Only the counts are saved — never the video.
