🏋️ PromptUps

Prompt Claude. Drop and give me ten.

Every time you prompt Claude Code, your webcam turns into a rep counter — squats and desk push-ups counted out loud by a trash-talking coach — and a chime tells you the second your code is ready. The AI gets smarter. Now you get stronger.

PromptUps demo: submitting a Claude Code prompt turns the scoreboard orange, the webcam counts squats as the coach calls each rep, and a chime marks Claude's reply — Hit enter. The scoreboard goes orange and the coach starts counting.

Why

A real Claude Code prompt takes thirty seconds to five minutes. Multiply by every prompt in a vibe-coding session and you're sitting on an hour of dead time a day — currently donated to your X feed.

PromptUps claims it back, with zero workflow change.

⌨️ You hit enter The scoreboard goes orange and the coach says go.
🎥 The camera counts MediaPipe pose landmarks, hysteresis thresholds, no honor system. Half reps don't count.
🗣️ The coach talks Every rep counted out loud, trash talk at milestones, a roast if you just stand there.
🔔 Claude replies Chime, rep summary, back to your diff.
📈 Stats accrue Today, all time, best set, prompts survived.

How it works

you hit enter ──► UserPromptSubmit hook ──► POST /promptups/start ──► camera counts reps
Claude replies ──► Stop hook             ──► POST /promptups/stop  ──► chime + set summary

init writes three hooks into ~/.claude/settings.json — it shows them to you, asks first, and backs up the file:

Claude Code event	What PromptUps does
`UserPromptSubmit`	Starts a set. Scoreboard orange, coach says go.
`Stop`	Ends the set. Chime, summary, back to work.
`Notification`	"CLAUDE NEEDS YOU" — amber alert, back to the keyboard.

Each hook is a curl with a one-second timeout that ignores failure, so Claude Code behaves identically whether PromptUps is running or not. The page listens on a server-sent-events stream and does everything else itself.

The camera is honest

Exercise	Counted from	Thresholds
Squats	knee angle (hip–knee–ankle)	down < 110°, up > 155°
Desk push-ups	elbow angle (shoulder–elbow–wrist)	down < 105°, up > 150°

Both run through a hysteresis state machine with smoothing and a minimum down-phase, so landmark jitter and quick bounces can't inflate your numbers.

The coach

The coach counts every rep through the Web Speech API and has opinions:

"Twenty-five seconds. Zero reps. The camera sees everything."

Default mode uses built-in line banks and works offline. Start with --ai-coach and end-of-set lines come from a claude -p Haiku call instead — one short generation per set, with the line bank as fallback. Mute it with the voice button; your household has opinions too.

Privacy

Every camera frame is processed by MediaPipe inside your browser tab and discarded. No camera frame is recorded or uploaded — no pixel of you reaches a server. The page pulls the MediaPipe runtime and pose model from CDNs on first load (~8.5 MB, cached after) plus two Google webfonts — none of those origins receive camera data. In default mode everything else is localhost; with --ai-coach the server also makes one claude -p call per set to Anthropic under your own account. Session totals — exercise, reps, timestamps — live in ~/.promptups/sessions.json.

Quick start

git clone https://github.com/Tatendaz/promptups && cd promptups
node bin/promptups.js init    # shows the hooks, asks first, backs up settings.json
node bin/promptups.js         # starts the server, opens http://localhost:7887

Allow camera access, pick your exercise, then go prompt Claude in your terminal — the page reacts on its own from there. No dependencies to install: the server is Node's http module. Not ready to wire the hooks? Hit test drive in the header at localhost:7887 to fake a prompt.

FAQ

Which cameras work?

Any the browser can see. The built-in webcam handles squats and desk push-ups. An iPhone via Continuity Camera shows up automatically on macOS — prop it against a wall and the floor comes into frame, which is what real push-ups and sit-ups need. USB webcams work too.

What's next?

Seated arm exercises (v0.2), standing exercises for the 1 m × 1 m box in front of your desk with squats counted from head movement (v0.3), then AirPods head-motion tracking so the camera becomes optional (v0.4) — then calories, streaks, and Apple Watch. The full plan is in ROADMAP.md.

How do I add an exercise?

It's the easiest PR: one entry in EXERCISES in public/reps.js — a joint triple per side, two angle thresholds, and a framing cue — plus a button in public/index.html and a case in tests/reps.test.js. Run npm test (57 tests, node:test, no dependencies) and open a PR. Coach lines live in public/coach.js; funny beats polite.

How do I uninstall it?

node bin/promptups.js uninstall removes only its own hooks and backs up settings.json first. rm -rf ~/.promptups if you also want your stats gone.
