Muay Thai shadowboxing with the camera counting every strike
Shadowboxing blind gets old fast. Nak Muay Cam detects jabs, crosses, hooks, elbows, knees and kicks in real time and closes the round with a scoreboard, combos and pace — free, in the browser, no sign-up. No video ever leaves your device.
How it works
From zero to your first round in under a minute.
Prop your phone, open the app
2–3 meters back, whole body in frame, at a slight angle to the camera. A chair does the job.
Allow the camera and throw
Pose detection runs on your device and counts strike by strike, splitting left and right like red and blue corners.
Finish the round, read the summary
Rounds with a bell, combos landed, strikes per minute and a pace chart to track progress session by session.
Strikes it detects
The classic weapons of Muay Thai, each with its own movement signature — and its original name.
Jab
หมัดตรง · Mat TrongThe lead-hand straight. Fast, right at the face — the metronome of your shadow work.
Cross
หมัดตรง · Mat TrongThe rear-hand straight with hip rotation. The app splits left and right on the scoreboard.
Hook
หมัดเหวี่ยง · Mat WiangThe bent-arm circular punch. Caps the classic 1-2-3, which the app recognizes as a combo.
Elbow
ศอก · SokMuay Thai's short-range weapon. Detected by the elbow leading the motion with a folded arm.
Knee
เข่า · KhaoKnee rising to hip line with the foot below — the clinch classic, counted per leg.
Kick
เตะ · TeThe Thai round kick, extended leg cutting at waist height. Each side on its own scoreboard.
No video ever leaves your device
Pose detection runs inside your browser (WebAssembly) — there's no server receiving footage, no account to create, no upload happening. Close the tab and it's gone.
Frequently asked questions
Does it work on my phone?
Yes. Open it in a current Chrome or Safari, prop your phone 2–3 meters away and keep your whole body in frame, at a slight angle to the camera. The scoreboard is designed to be read from a distance.
Do I need to install anything?
No. It runs straight in the browser — no app store, no download, no updates.
Is it really free?
Yes — 100% free, no sign-up, no ads, no paid-plan catch.
Does it work offline?
You need internet to load the page. After that, detection runs entirely on your device — your video is never uploaded anywhere.
Do I need any gear?
No. About 2×2 m of clear space and a propped-up phone is all it takes. Wraps are optional — it's shadowboxing, no impact.
How does it detect strikes?
A computer-vision model estimates 33 body landmarks every frame, and speed/extension heuristics classify each strike. More on the blog.
